Utilization of biofloc pond water as a substitute for nutrition in the pak choi hydroponic system

Increased fish consumption needs can be overcome by high stocking density in fish farming. Stocking density and high feeding rise the problem of increasing organic waste which can reduce water quality. Biofloc technology is one alternative that can overcome this problem by adding the amount of organic carbon in the pond, thereby increasing the C / N ratio of water that will grow heterotrophic bacteria. The basic principle of biofloc technology is the assimilation of inorganic nitrogen by heterotrophic microbial communities in cultivation media which can then be utilized by aquatic organisms as a food source. The government through the Ministry of Marine Affairs and Fisheries promotes freshwater fish farming with biofloc technology. The objective of this research was to assessing the effect of biofloc pond water on pak choi growth. The research was conducted for two months, planting the pak choi in pipe line using rockwool as its growth media. The cultivation used two treatments, biofloc pond water and ab mix as its nutrition. The result showed that pak choi growth with biofloc pond water was lower than ab mix nutrition.

Exploring institutional arrangements for local fish product labelling in Tuscany (Italy): a convention theory perspective

Increasing fish consumption along with rising competition in the global seafood market has brought fisheries and aquaculture producers to adopt several differentiation and marketing strategies. Labelling schemes were thus introduced to respond to a growing demand for traceable and sustainable products. However, the proliferation of quality labels brought to general confusion, calling for collective and public fish labels to ease decision-making. In our case study region (Tuscany, Italy), a number of policy-driven efforts were deployed for establishing regional labelling schemes for fisheries products with no observable impact on the market. Meanwhile, local companies have implemented a number of successful private and regional labels. The purpose of this research is to contribute to potential options for collective regional labelling schemes of fisheries and aquaculture products, through a case study analysis, building on agro-food value-chain and management approaches. Our empirical results highlight key issues and perspectives on labelling policies for local fisheries and aquaculture products.

REUSE OF COLLAGEN AND HYDROXYAPATITE FROM THE WASTE PROCESSING OF FISH TO PRODUCE POLYETHYLENE COMPOSITES

In recent years, the increase in the generation of waste (e.g., bones and skin) from the processing of fish-based food related to the increase in fish consumption and the accumulation of synthetic polymers in the environment are causing major environmental concerns. Hydroxyapatite (HA) extracted from the bones and collagen from the skin of fish processing residues can be combined with synthetic polymers to maximize the use of waste material derived from fish while simultaneously reducing the use of synthetic polymers. Hence, in this study, collagen and HA were extracted from the carcasses of Lophiosilurus alexandri, and the obtained materials were reused to prepare low-density polyethylene (LDPE) blends and composites. The integrity of the triple helix structure of collagen was confirmed by FTIR and DSC showing that there was no collagen denaturation during its extraction and sample processing. The results indicated that the material produced by the incorporation of collagen into LDPE compatibilized with polyethylene-graft-maleic anhydride exhibits good mechanical and surface properties for use as a support material for ornamental articles, among other applications.

Assisting sustainable food consumption: The effects of quality signals stemming from consumers and stores in online and physical grocery retailing

Increased fish consumption can contribute to a more sustainable food system. This paper explores how signaling affects consumer choices in fresh fish purchasing situations, both in traditional and online retail settings. We examined two different types of market signals; quality signals stemming from consumers as a social proof and authority signals coming from stores. Study 1 showed that quality signals from other consumers (product rating) had the highest importance score in an online setting when compared to traditional attributes in a conjoint experiment. Study 2 again confirmed the prominence of quality signals from consumers by extending the research over to brick and mortar retailing and top-selling items. Study 3 followed up with in-store experiments, using fresh cod fillets as the target product and fresh ground beef as a comparison. The experiments showed increased sales from both types of signaling, with an overall 41.5% increase for fish in our study.

Pysicochemical Characterization of Nano Calcium phosphate from Milkfish's (Chanos - Chanos Forks) Bone Flour in Duration of Autoclaving and Boiling Time Different

According to the Food and Agriculture Organization in 2018, milkfish 1,188,000 tons (2016) or 2% of the world's total fish (2016) (The State of World Fisheries and Agriculture, 2018). South Sulawesi milkfish production is the highest in Indonesia. Milkfish production in 2016, to 127,434.1 tons (Anonymous, 2018). Milkfish is a fishery commodity in Pangkep Regency, in 2016 has increased by 28,759 tons (Anonymous, 2018), an increase in fish consumption it will also increase of milkfish bone waste. The use of milkfish bone waste as a source of calcium is an alternative provide a calcium-rich food source. The purpose of this research is to study the physicochemical of milkfish bone calcium phosphate with in duration of autoclaving and boiling time differently. The treatment are in duration of autoclaving (A) A1 = 1,5 , A2 = 2, and A3 = 2,5 hours, and boiling time (B) B1 = 30 , B2 = 60 and B3 = 90 minute. The design used is complete randomized design with two factors, consist of three level. Each treatment was repeated three times. The data analysis by variance analysis using SPSS V. 21 software. The parameters measured are yield, water, ash, protein, fat, calcium and phosphorus. Milkfish bone in this study contained the highest calcium 41.87% and phosphorus 25.86% obtained from a combination of 2.5 hours autoclaving and boiling length 90 minutes. Yield 36.59%, moisture 5.22%, ash 77.87%, protein 25.13%, and fat content 4.01%.

GRANGER CAUSALITY POLA KONSUMSI IKAN DI ACEH TENGAH MENGGUNAKAN ANALISISI VECTOR ERROR CORRECTION MODEL (VECM)

Development of human resources is very important in promoting economic growth, because humans are not only objects in development but also play a role as a subject. Stunting is a major problem that inhibits the quality of human resources, to reduce the amount of human development that lives by stunting is to increase the consumption of protein contained in fish. This study aimed to determine the pattern of fish consumption in Central Aceh and the variables that affect fish consumption. The analytical model used is the granger causality analysis, through the Vector Error Correction Model (VECM) analysis model. The results of this study indicate that the pattern of fish consumption in Central Aceh was not only influenced by income, but also influenced by the amount of chicken meat and egg consumption Increased income does not have a positive effect on increasing fish consumption but affects the amount of chicken meat and egg consumption. To increase the amount of fish consumption in Central Aceh, efforts to increase the amount of fish supply through local fish farming activities and the socialization of fish eating.

How do dietary choices affect the environment? The nitrogen footprint of the European Union and other dietary options

There is a growing interest in diets with respect to health and fitness. However, food production and consumption have been identified as major sources of environmental impacts. In this study, the maximum nitrogen (N) footprint of the European Union has been used as an indicator to describe the reactive nitrogen losses using food consumption and production data. The maximum N footprint for the European Union food supply was 23.8 kg N/capita/year and the main food categories contributing to this footprint were dairy, pork, and cereals. Additionally, the N footprint was calculated for five dietary patterns: vegan, lacto-ovo vegetarian, pesco-vegetarian, semi-vegetarian and non-vegetarian. Dietary preferences towards a vegan and a lacto-ovo vegetarian diet showed a reduction in the total N footprint of 25% and 24%, respectively, with respect to the non-vegetarian diet. The pesco-vegetarian and semi-vegetarian diet presented also a reduction in the amount of N released, 17% and 15%, respectively. Although the semi-vegetarian diet includes the consumption of meat and meat production is less N-efficient than fish production, a tradeoff is observed by the increase in fish consumption resulting in similar N footprints. Assessing different dietary patterns and analyzing possible changes in food consumption can lead to significant improvements in the N footprint. This study can serve as the starting point to consider food consumption as a way of influencing to some extent the environmental impacts produced by N release.

Does Fresh Air make the Difference; a Comparative Study in Vitamin D Status among College Adolescent Females from Giza and Red Sea Governorates

The level of air pollution is negatively associated with the amount of solar ultra-violet ray B (UVB) that reaches earth surface. So, more pollutant areas lead to less UVB passage and consequently, 25 (OH) vitamin D cutaneous syntheses reduces. The research was carried out to study the effect of some biological, behavioral, and environmental factors on vitamin D level among college adolescent females from Red Sea and Giza governorates. A convenient sample consisted of 151 first grade university female youth was selected. Written consent was an initial basic step. Vitamin D intake was assessed and serum calcium, phosphorus, alkaline phosphatase, 25-hydroxyvitamin D [25(OH) D], and parathyroid hormone (PTH), were measured. Food intake was compared to the recommended dietary allowances. Results revealed that majority of respondents (92.0%) were veiled and exposed to sun at noon time and 61.0 % mentioned that sun- exposure took more than an hour. Waist circumference (WC) and waist to height ratio (WC to Ht) in Giza sample and increased fish consumption per week in Red Sea sample showed a positive effect on vitamin D status. Spring season had a negative influential effect on Giza participants. This study concluded that lack of sun exposure as the main cause of vitamin D deficiency in college female, there is also limited awareness of the association between sun exposure and vitamin D synthesis. Fresh air and good food practices could aid in solving health problems with such an influence as hypovitaminosis D. This study emphasized the need for further vitamin D assessment and intervention by supplementation or fortification of a staple food item. There is also an urgent need for public education to improve vitamin D- related practice and to minimize health hazards of improper exposure to UV B rays.

Pengembangan potensi lokal ikan menjadi nugget dan abon ikan untuk meningkatkan kesejahteraan masyarakat dan menurunkan angka kejadian stunting di Kanigoro, Saptosari, Gunungkidul

Kanigoro Village is blessed abundantly with great potential for fish resources development. Its strategic location by the seashore also poses an opportunity for Kanigoro to become a center for local home-based culinary industries focusing on local fish, such as fish nuggets and floss (shredded meat), which are rich sources of animal protein. Despite the plentiful local protein sources, a high prevalence of stunting continues to plague Kanigoro Village, reaching up to 48.2%. Developing fish-based culinary industries may become a means to reduce the stunting rates as well as to improve the economic status of the villagers. This project aimed to develop the fish-based local food processing into nuggets and floss to improve family economies and nutritional status in Kanigoro Village through a community-based approach. It began with the sharing of the project plan to gain support from the community. The team collaborated with local Kanigoro organizations, namely posyandu cadres and women's group. The training was given to the women's group on marketing, such as providing nutritional information on the packages, developing attractive packaging, and introducing marketing niches. Posyandu cadres were trained to motivate the villagers to increase fish consumption. After the training, the groups conducted meetings with the local women under the supervision of the team. In the meeting sessions, they encouraged villagers to eat more fish. Through the training, the local women acquired new knowledge on product enhancement, starting from improved processing hygiene, upgraded packaging, provision of nutritional information, and innovative marketing ventures. In the gatherings, posyandu cadres were able to deliver motivation to augment fish consumption. They could measure the height and weight of children under five correctly, enabling them to identify children with stunting. The knowledge and skills acquired from this project will equip the local villagers to prevent and reduce stunting prevalence in Kanigoro Village.

The Contribution of Fish to Food and Nutrition Security in Eastern Africa: Emerging Trends and Future Outlooks

：Approximately 200 million people in Africa derive high-quality and low-cost proteins from fish. However, the consumption of fish is not fully exploited to combat the “triple burden” of malnutrition—obesity, undernutrition, and micronutrient deficiencies which are the leading causes of poor health in the region. There is still limited knowledge on quantitative information to guide policy makers in developing evidence-based actions that can improve the availability of and access to nutritious food for healthy and sustained diets among children and care givers. In this paper, we review the available literature with the aim of assessing and quantifying the extent to which fish contributes towards fighting food and nutrition insecurity in the Eastern Africa subregion. Key results reveal the region is characterized by fish supply deficits, and hence, low levels of fish consumed per person. Nonetheless, the increase in fish imports, and the growing supply of fish from aquaculture are likely to improve the per-capita fish intake. Fish trade is generally bidirectional, with exports exceeding imports in value terms, while significant challenges still hinder domestic and intra-regional fish trade. The Eastern Africa region is projected to realize increased fish consumption from 4.80 kg in 2013 to 5.49 kg by 2022. Rising population growth and income levels imply that the region will need 2.49 million tonnes of fish to fill the demand–supply gaps. We recommend that food security and nutritional programmes should recognize the potential of fish in providing essential micronutrients from the aspects of improved dietary quality, nutritional status, and general wellbeing of the region’s fast growing population.

Konsumsi Ikan dan Potensi Anisakiasis: Aspek Komunikasi Kesehatan Masyarakat Suatu Program Pemerintah

Communication in the health sector plays an important role in the context of educating people and the society. Theemphasis is rely primarily on promoting health so that behavior changes occur. One of the example is a governmentprogram “GEMARIKAN” which was designated to increase fish consumption in the community. Unfortunately, thetriumph upon this programme is overshadowed by the potential transmission of zoonotic infections of the nematodeworm named Anisakis spp. This worm can caused a potentially fatal and deadly disease called anisakiasis. This risk canbe reduced by re-conducting numerous education in the community regarding these parasites, their life cycles, its hostbehaviors and lifestyles that can facilitate transmission such as eating fish in raw conditions and the need of goodhandling practices of fish to avoid transmission to occur.

The potential of insect meal in improving food security in Malawi: an alternative of soybean and fishmeal in livestock feed

It is reported that fish contribute 70% of the animal protein intake in Malawi. This may be currently lower, as per capita fish consumption is reported to have declined by 58% from 14 kg/person/year in the 1970s to 8.12 kg/person/year in 2014. The situation poses a serious national nutrition problem, if not put under control. The Malawi Government and other stakeholders were therefore prompted to promote fish farming to supplement the fish that are provided from capture fisheries on the market. Currently, Malawi Development Cooperation (MALDECO) Aquaculture is a prominent commercial aquaculture company in Malawi, with just above 6,000 small-scale farmers. Feed is a challenge due to the high prices of soybean and imported fishmeal. Most small-scale fish farmers use maize bran to feed their fish, but this is nonviable as it results in low yield and abandonment of fish farming by most farmers. This study seeks to provide information in search of a solution to address feed challenges in the fish sector. A literature review was conducted on approaches being used by fish farmers and current efforts to resolve these challenges, and the information gained was used to outline a roadmap for solving livestock feed challenges at household level in Malawi. It was observed that using waste from the farmyard, farmers could culture insects which have high protein content than soybean and highly digestible than fish meal. Insects can deal with environmental pollution by utilising waste. Incorporation of insect meal in fish feed can replace soybean and fish meal, hence turning the fish industry around in Malawi by making it more productive. The goal of making fish products adequately available on the market may rely on the potential of incorporating insect meal in fish feed. Insect inclusion in fish feed has a potential for increasing fish consumption per capita in Malawi, hence improving food security. However, challenges to be resolved are food acceptance, food safety issues and legislation, which can be dealt with by the coordination of government, industry and academia.

The UN and Its Agencies in the Development of Regulations on Management and Conservation of Fisheries: A Plurality of Initiatives but Questionable Coherence

Although various organizations have been established for the management and conservation of fisheries and these have contributed to the establishment of common regulations pertaining to the management of fisheries on a global or regional level, current measures for the management and conservation of fish resources do not appear to be very effective. This article attempts to clarify the current problems involved in the management and conservation of fisheries and what kinds of regulations are necessary to manage sustainable fisheries effectively in an era of increasing fish consumption.

Simultaneous double cationic and anionic molecule separation from herring milt hydrolysate and impact on resulting fraction bioactivities

Abstract The increase in fish consumption, over the last twenty years, is linked to by-product production, rich in valuable compounds such as proteins, vitamins, minerals or lipids (omega-3). Milt herring hydrolysate, containing different molecules, has been fractionated by electrodialysis with ultrafiltration membrane (EDUF) in a new configuration using four ultrafiltration membranes, allowing a simultaneous and double fractionation of anionic and cationic molecules. Four fractions were recovered, each were concentrated in compounds of low molecular weight (

Effects of methylmercury and retinol palmitate co-administration in rats during pregnancy and breastfeeding: Metabolic and redox parameters in dams and their offspring

Ubiquitous low-dose methylmercury (MeHg) exposure through an increased fish consumption represents a global public health problem, especially among pregnant women. A plethora of micronutrients presented in fish affects MeHg uptake/distribution, but limited data is available. Vitamin A (VitA), another fish micronutrient is used in nutritional supplementation, especially during pregnancy. However, there is no information about the health effects arising from their combined exposure. Therefore, the present study aimed to examine the effects of both MeHg and retinyl palmitate administered on pregnant and lactating rats in metabolic and redox parameters from dams and their offspring. Thirty Wistar female rats were orally supplemented with MeHg (0,5 mg/kg/day) and retinyl palmitate (7500 µg RAE/kg/day) via gavage, either individually or in combination from the gestational day 0 to weaning. For dams (150 days old) and their offspring (31 days old), glycogen accumulation (hepatic and cardiac) and retinoid contents (plasma and liver) were analyzed. Hg deposition in liver tissue was quantified. Redox parameters (liver, kidney, and heart) were evaluated for both animals. Cytogenetic damage was analyzed with micronucleus test. Our results showed no general toxic or metabolic alterations in dams and their offspring by MeHg-VitA co-administration during pregnancy and lactation. However, increased lipoperoxidation in maternal liver and a disrupted pro-oxidant response in the heart of male pups was encountered, with apparently no particular effects in the antioxidant response in female offspring. GST activity in dam kidney was altered leading to possible redox disruption of this tissue with no alterations in offspring. Finally, the genomic damage was exacerbated in both male and female pups. In conclusion, low-dose MeHg exposure and retinyl palmitate supplementation during gestation and lactation produced a potentiated pro-oxidant effect, which was tissue-specific. Although this is a pre-clinical approach, we recommend precaution for pregnant women regarding food consumption, and we encourage more epidemiological studies to assess possible modulations effects of MeHg-VitA co-administration at safe or inadvertently used doses in humans, which may be related to specific pathologies in mothers and their children.

Exploring solutions for healthy, safe, and sustainable fatty acids (EPA and DHA) consumption in The Netherlands

Advisory bodies such as the World Health Organization and the Dutch Health Council (DHC) recommend including fatty fish in one’s diet, based on the health benefits of their content of n − 3 poly unsaturated fatty acids (eicosapentaenoic acid—EPA and docosahexaenoic acid—DHA) being, i.e., the reduction of the risk of fatal cardio vascular disease and stroke. These dietary advices on these fatty acids’ (e.g., fatty fish) consumption are only based on the expected health benefits. But what would a dietary advice look like when the health benefits were weighed up against relevant sustainability and food safety considerations? The aim of the current study was to explore the consequences for safety, health, and sustainability of solutions to meet the DHC’s recommendation on EPA/DHA consumption. To this end, first, the health, food safety, and sustainability perspectives of the current fish production and consumption, being the main source of EPA/DHA, were identified. Second, alternative diet scenarios, meeting the daily advised intake of EPA/DHA, were collected and subsequently judged on their health, safety and (environmental) sustainability characteristics. To enable structuring the process of finding solutions for such complex problems, a specific framework was applied: solution-focused sustainability assessment. Based on stakeholder consultation, three scenarios were assessed: higher production and consumption of fatty fish (here: farmed salmon); increased human use of by-catch and discards; and increased consumption of alternative EPA/DHA sources (here: walnuts). It appeared that only in the scenario of increased use of by-catch and discards, the effects on human health and the environment and resources coincide, whereas in the other two scenarios, the positive health effects are expected to result in one or more negative effects on the environment. Besides, increased fish consumption causes more food safety problems; however, if one changes his/her diet and replaces meat by fish, this will lead to a net higher food safety. The analysis shows the sustainability limits of increased production and consumption of fatty fish and alternative EPA/DHA sources. This can support policy makers in setting goals and deciding on measures to encourage healthy and environmentally sustainable fish (i.e., EPA/DHA) consumption. Furthermore, this study shows in general the impact a policy initiative focusing on health aspects only can have on other aspects, such as environment and food safety. It emphasizes the added value of integrative assessments, which cover multiple effects when designing new sustainable policies.

Aquaculture, fish resources and rural livelihoods: a village CGE analysis from Namibia’s Zambezi Region

Aquaculture is widely recognised as a way to reduce malnutrition and poverty. So far, research has mainly focused on Asia, and the few studies available from sub-Saharan Africa are predominantly ex-post partial analyses. By constructing a village computable general equilibrium (CGE) model, we aim to investigate whether aquaculture improves local livelihoods and simultaneously has the potential to counteract local overfishing. We apply this to a rural case study region in Namibia where malnutrition, poverty and fish resource overexploitation are current problems. Our village CGE model shows that aquaculture would be a viable livelihood activity improving household incomes and utility through labour reallocations. Furthermore, aquaculture can counteract malnutrition through increased fish consumption. Higher opportunity costs lead to households leaving the fisheries and switching to aquaculture. These substitution effects offer the possibility of reducing the pressure on local freshwater fish stocks. Policy makers can use the results to introduce aquaculture interventions in rural areas. Our findings indicate that such interventions should take particular account of the poorest households, which are most dependent on fisheries. The derived opportunity costs provide information about payments that are necessary to make policy interventions acceptable for different household groups.

Changes in Fish Consumption Desire and Its Factors: A Comparison between the United Kingdom and Singapore

It is widely known that rapid population growth and income improvement in some developing countries, and growing health consciousness in some developed countries, are the main factors that have contributed to the global increase in the consumption of fishery products in the past few decades. While a detailed analysis of fish consumption behavior is being conducted in several countries, there are other countries where changes in fish consumption desire and their social and psychological factors are not fully clarified. This study investigates the changes in fish consumption desire and its associated factors in the United Kingdom (UK) and Singapore. Primary data were gathered from 1200 participants through a web questionnaire survey in the UK and Singapore. The results show that approximately five times as many respondents stated that the desire to purchase fish had increased in both the UK and Singapore compared to those that believed it had not 10 years ago. Second, the increase in fish consumption in the UK is positively associated with younger age, cheaper price, the health benefits of fish, concern over the health of meat, and religion. Third, the increase in fish consumption in Singapore is positively associated with cheaper prices and is negatively associated with concerns over sustainability.

Iodine and Pregnancy-A Qualitative Study Focusing on Dietary Guidance and Information.

Iodine is essential for thyroid hormones synthesis and normal neurodevelopment; however, ~60% of pregnant women do not meet the WHO (World Health Organization) recommended intake. Using a qualitative design, we explored the perceptions, awareness, and experiences of pregnancy nutrition, focusing on iodine. Women in the perinatal period (n = 48) were interviewed and filled in a food frequency questionnaire for iodine. Almost all participants achieved the recommended 150 μg/day intake for non-pregnant adults (99%), but only 81% met the increased demands of pregnancy (250 μg/day). Most were unaware of the importance, sources of iodine, and recommendations for iodine intake. Attitudes toward dairy products consumption were positive (e.g., helps with heartburn; easy to increase). Increased fish consumption was considered less achievable, with barriers around taste, smell, heartburn, and morning sickness. Community midwives were the main recognised provider of dietary advice. The dietary advice received focused most often on multivitamin supplements rather than food sources. Analysis highlighted a clear theme of commitment to change behaviour, motivated by pregnancy, with a desired focus on user-friendly documentation and continued involvement of the health services. The study highlights the importance of redirecting advice on dietary requirements in pregnancy and offers practical suggestions from women in the perinatal period as the main stakeholder group.

Association between fish consumption and risk of dementia: a new study from China and a systematic literature review and meta-analysis.

To assess the association of fish consumption with risk of dementia and its dose-response relationship, and investigate variations in the association among low-, middle- and high-income countries. A new community-based cross-sectional study and a systematic literature review.SettingsUrban and rural communities in China; population-based studies systematically searched from worldwide literature. Chinese adults aged ≥60 years in six provinces (n 6981) took part in a household health survey of dementia prevalence and risk factors. In addition, 33 964 participants from eleven published and eligible studies were included in the systematic review and meta-analysis. In the new study in China, 326 participants were diagnosed with dementia (4·7 %); those who consumed any amount of fish in the past two years v. those who consumed no fish had reduced risk of dementia (adjusted OR=0·73, 95 % CI 0·64, 0·99), but the dose-response relationship was not statistically significant. The meta-analysis of available data from the literature and the new study showed relative risk (RR) of dementia of 0·80 (95 % CI 0·74, 0·87) for people with fish consumption; the impact was similar among countries with different levels of income. Pooled dose-response data revealed RR (95 % CI) of 0·84 (0·72, 0·98), 0·78 (0·68, 0·90) and 0·77 (0·61, 0·98) in people with low, middle and high consumption of fish, respectively. Corresponding figures for Alzheimer's disease were 0·88 (0·74, 1·04), 0·79 (0·65, 0·96) and 0·67 (0·58, 0·78), respectively. Greater consumption of fish is associated with a lower risk of dementia. Increasing fish consumption may help prevent dementia worldwide regardless of income level.
