Emerging challenges in maintaining marine food-fish availability and food safety.

The marine finfish and crustaceans contribute immensely to human nutrition. Harvesting marine food-fish to meet the global demand has become a challenge due to reduction of the fishery areas and food safety hazards associated with increased pre-harvest and post-harvest contaminations. The causes of low fish availability and contaminations were reviewed following the published literature from 2000 to 2023. The marine fish yields are stressed due to spread of contaminants triggered by rising sea temperatures, transport of microorganisms by marine vessels across the oceans, anthropogenic activities leading to increase in the toxic microorganisms, and the entry of toxic chemicals and antibiotic residues into the seawater through rivers or directly. Processing adds pyrogenic chemicals to foods. The hazardous materials may accumulate in the food-fish, beyond tolerance limits permitted for human foods. While the research and control measures focus on minimizing the hazards due to pathogenic microorganisms and chemicals in market fish, there is less discussion on the unhealthy changes occurring in the oceans affecting the quantity and quality of food-fish, and the origins of microbial and chemical contaminations. This review examines the factors affecting availability of wild food-fish and increased contaminations. It aims to bridge the knowledge gaps between the spread of hazardous agents in the marine environment, and their effects on the food-fish. Meeting the future human food security and safety through marine fish and fish products may need marine cage farming, introduction of genetically modified high yielding food-fish, and cultured contaminant free finless fish muscles as options.

Assessment of fresh fish value chain stakeholders’ food safety knowledge and pratices at the Medina Coura market in Bamako, Mali

Fish is indeed the most important source of animal protein in the diet of the Malian population. However, in view of the multiple manipulations it undergoes from its capture to its sale, it is subject to multiple cross contaminations which constitute threats to its safety. The study aimed to assessing the level of food safety knowledge and practices among the fish sellers in Medina Coura market at Bamako with the fishermen in four fishing areas (Selingue, Manantali, Markala and Mopti) located along the Niger and Senegal rivers in Mali. A structured face-to-face questionnaire was designed and administered to 247 respondents (117 fishermen and 130 selllers) were interviewed in the value chain between November 2018 and February 2019. Data on demographics, business characteristics, knowledge and practices in food safety was collected by purposive sampling methods, descriptive analyses were done with frequencies and summary statistics. Chi-square statistics were computed to determine significant relationships and the p-value was set at 0.05 significant level. The majority of sellers were female (84.6%) and fishermen were male (100%) with the majority of both being above 40 years of age. Fishermen and sellers at Bambara had primary education (63.3% respective) while fishermen at Bozo had no formal education (78.6%). Spearman's correlation coefficient revealed that knowledge has significantly influenced the fish safety practices of the fishermen (P < 0.05). However, age and duration of service had no effects on the fish safety knowledge of the fishermen (P > 0.05). Fish safety knowledge of the vendors has a significant positive impact on their safety practices. Respondents having received no formal education in food safety. It was more exposed to bad practices at the level of sellers than fishermen. In view of the above, it is, important to put in place a good public health management strategy for food sales services which will give them the knowledge and skills necessary to provide hygienic and safe sales services.

Unseen annihilation: Illegal fishing practices and nautical patrol

A host of regulations should protect fish, a common-pool resource, from overexploitation, but detecting violations of these regulations is challenging, both at sea and in port. We present a novel approach to uncover a supposedly widespread and particularly harmful illegal fishing practice, the use of nets with illegally small mesh size. Our approach relies on readily available data on reported fish landings. We focus on bottom trawling, the world’s most widely used fishing method. We exploit the fact that using illegally small mesh size increases the share of small fish in the catch. Using quasi-random variation in nautical patrol as a source of variation in the incentive to comply, we show that in weeks without patrol the share of small fish in the landed catch is systematically larger than in adjacent weeks with patrol. Our results are in line with widespread use of illegally small mesh. The resulting catch and discard of juvenile fish is many times larger than the gain in the catch of marketable fish. This harm has thus far been largely ignored in estimates of the externalities from fishing.

Small-Scale Marine Fishers’ Possession of Fishing Vessels and Their Impact on Net Income Levels: A Case Study in Takalar District, South Sulawesi Province, Indonesia

Over the last two decades, the growth of the fisheries sector in Indonesia has shown an increasing trend; however, behind the rapid development of this sector, the role of small-scale fisheries as one of the main actors supporting the whole industry is often neglected. They remain poor and continue to conduct fishing activities traditionally. Therefore, this study aims to describe the real situation of small-scale fishers, analyzing the fishers’ ownership of the boat they use, analyzing their income level to reveal their poverty status, and analyzing the factors affecting their income. The regression analysis results indicate that boat category, sea fish catch, fish selling price, fixed costs, and variable costs have significant effects on fishers’ net incomes.

Economic Characteristics of the Fishing Society of Cangkol Village, Cirebon, Indonesia

The welfare of the fishing community in Cirebon City indicates that management and development are not equally distributed. The management and development carried out will not run optimally if there is no in-depth understanding of the characteristics of the regional community. This research aims to map economic characteristics, as well as to analyze the driving and inhibiting factors of the fishing community in Cangkol Village. The research was carried out in April–June 2023. The result showed that the average income of skipper fishermen was Rp. 3,288,195.83, while the average wage for crew members was Rp. 1,183,250.00/month. The fishing community in Cangkol Village are fishermen with a traditional fishing unit with a 3 GT boat, hand line fishing gear, and a one-day fishing system. The types of fish caught are Lutjanus rusellii, Diagramma melanacrum, Lutjanus bitaeniatus Cephalopholis boenack, Scombroides tala, and other fish. The caught fish market is a monopoly. Marketing of catches through two channels, namely through middlemen or directly to consumers with a door-to-door promotion system.

Analysis of Demand for Fish in Urban Malawi

The purpose of this study was to find the drivers of demand for various fish species in urban Malawi. Previous demand studies on the fisheries sector in Malawi have, mainly, treated fish as a homogenous commodity thereby making information regarding households’ general consumption patterns for different fish species scanty. This study, therefore, concentrates on the disaggregated analysis of the demand for the major fish species caught and consumed in Malawi. It focuses on fish from both capture fishery and aquaculture sub-sectors namely; Engraulicypris sardella (usipa), Copadichromis spp (utaka), Lethrinops spp (kambuzi); Clarias gariepinus (mlamba); Rhamphochromis spp (mcheni); Barbus Paludinosus (matemba); and Lake Malawi tilapia (chambo). It employs primary data collected from the households in Blantyre city using a multistage stratified random sampling method. Results show that the demand for usipa is influenced by a household’s location in a high-density area, and has low-income levels. Utaka, on the other hand, is positively influenced by the age of the household head and the number of people employed in the household while chambo is positively influenced by the high education level of the household head, high-income levels, and the household’s location in the high-density areas. The study has also found that mcheni and mlamba are positively influenced by income levels while the demand for matemba is positively the household head’s state of being married but it is negatively influenced by the number of children in the household. Policy implications arising from this study are that in the course of carrying out market segmentation, the fish marketers in Malawi must concentrate on selling usipa to households in high-density areas and focus on households with low-income levels. The selling of utaka while chambo should mainly be sold to households whose heads have high education, have high-income levels, and are located in high-density areas.

First Report of Proteocephalus longicollis (Zeder, 1800) in Alosa fallax lacustris (Fatio, 1890) from Lake Garda (Italy): Morphological and Molecular Study.

Twaite shad (Alosa fallax) includes two subspecies, the anadromous Alosa fallax nilotica, and the landlocked species Alosa fallax lacustris, representing the only Clupeidae inhabiting Lake Garda. Study of the parasitic fauna of this species in this area is still limited. For this reason, the aim of the present study was to evaluate the presence of tapeworms from A. fallax lacustris sampled in Lake Garda. Sixty-six A. fallax lacustris specimens were collected at the Milan fish market (Lombardy, Italy); specifically, an evaluation of the gastrointestinal contents was carried out for the presence of helminths. All parasites found were fixed in 70% ethanol and transferred to the laboratories of the University of Messina for morphological and molecular analysis. Parts of the parasites were stained with Semichon's carmine red technique. Molecular analysis was carried out using LSU rRNA and ITS2 region genes. Eight specimens out of sixty-six (12.1%) were positive for adult cestodes within the pyloric caeca. Morphological and molecular analysis could to identify the parasites found to be Proteocephalus longicollis. This parasite species is not considered a zoonotic agent, representing a low risk of parasitic fish-borne zoonosis for consumers of this appreciated fish from Lake Garda.

ORGANIZATIONAL AND ECONOMIC MECHANISMS OF ATTRACTING INVESTMENTS IN THE AQUACULTURE SECTOR

Topicality. The role of aquaculture in the agricultural structure of Ukraine is difficult to overestimate. During the times of independent Ukraine, the production volume of this industry has been decreasing every year.

Socio-Economic Potential Of Fishermen In Pulau Banyak, Aceh Singkil

Communities in Pulau Banyak District on average work in the fisheries sector as fishers. Pulau Banyak fishers take advantage of the potential of captured fisheries as their main source of income. The living conditions of fishers are often classified as a marginal group close to poverty. This study aims to examine the socio-economic conditions of fishers in the Pulau Banyak District of Aceh Singkil. The method used is to conduct a field survey using a questionnaire (interview). The location of the research was in Pulau Banyak District, Aceh Singkil Regency. The results of the study show that the social conditions of the Pulau Banyak people work as fishers with a low level of education, at most equivalent to elementary school. The economic condition of the fishers on Pulau Banyak is seen based on their main income and also other income sourced from side income and the income of family members who help fishers. The main source of income for fishers is an average of IDR 1,000,000-1,500,000 per month with an average trip of 6 times a week or 24 times a month with catches of 8 types of fish. While the pattern of fish marketing, the average fishers as much as 64 percent choose to sell to bench shops. The government has an important role in monitoring the marketing pattern of fishery products and implementing policies for optimal and sustainable utilization of fishery resources.

Women fish vendors in Kerala, India: an analytical study of access to inputs and services

Women are predominantly engaged in postharvest fisheries and comprise about 75% of those engaged in fish marketing in India. The roles performed by fisherwomen are often not recognized. With the recent penetration of technology, mechanization, and capital orientation in fishing and fish vending, the business atmosphere has further turned against the interests of women. Women have to face competition in accessing fish, availing a prospective selling space, locating customers at their preferred time, and to adjust with the changing consumer preference to provide fish in a ready-to-cook form. With this background, a study was undertaken among women fish vendors of the south Indian state of Kerala, to analyze their access to inputs and services and to collect gender-disaggregated data. A large level of regional variation was observed in terms of the involvement of women in fish vending owing to established cultural norms. There exists skewed access to inputs and services like fish, credit, ice, infrastructure facilities, transportation, and storage facilities for women in the state. Women with poor social and economic networking were less privileged to have an incremental income from their traditional fish vending. There was a clear indication of the influence of financial capabilities such as employment days, volume, and variety of fish handled in determining the daily income of vendors. The inability to invest in fish vending activities was found to influence daily revenue. We recommend the convergent efforts of various organizations to enhance the livelihood status of fisherwomen

Assessment of Food Safety Practices among Smoked Fish Sellers in Ekiti State, Nigeria

This study was carried out to assess the food safety practices among the smoked fish sellers in Ekiti State, Nigeria. It aimed at describing the socio-economic characteristics of the smoked fish sellers; identifying the food safety practices, examining the determinants of using food safety practices, estimating the profitability of smoked fish and ascertaining the constraints to food safety practices among smoked fish sellers in the study area. Data, obtained through a multi-stage sampling technique, were analysed through the use of descriptive statistics and Tobit regression models. Result from socio-economic characteristics of the respondents revealed that smoked fish business was dominated by females (75.8%) who were majorly young people with the mean age of 45.5years. The majority of the respondents were married (59.1%). It was also revealed that most of the respondents were literate with different levels of education with the average family size of 6 persons. The respondents were fairly experienced with 41.7% of them had more than 10 years of involvement in smoked fish enterprise. Most of the respondents used charcoal (53.4%) and half drum kiln (57.5%) in smoking their fish. A larger percentage (33.3%) of the respondents sourced their capital from other sources. Majority (61.7%) of the respondents smoked other species of fish such as hake fish and herring fish etc. The smoked fish sellers (68.3%) had prior knowledge of food safety practices while the respondents (57.5%) had access to useful food safety practices. The majority (73.3%) of the respondents had no access to bank loans. This study revealed that the majority of the smoked fish sellers were food safety compliant. It revealed that the major food safety practices used by the respondents were sweeping of their workspace before and after processing (99.2%) and washing of their hands before and after processing (97.5%) The only place they were lacking was in the covering of their smoked fish, the study revealed only few (32.5%) of the smoked fish sellers covers their smoked fish. On the cost and returns, the study revealed the mean value of total cost to be ₦305,690 and the mean amount of the total income generated by the respondents to be ₦495,850. The total income was greater than the total cost, which implies that the business was profitable. The results of Tobit regression model analysis revealed that age, level of education, family size and access to useful food safety practices were found to significantly influence the number of food safety practices used by the respondents in the study area. On the constraints to the use of food safety practices, the study revealed that the respondents were facing different problems and the most prominent problem was the lack of storage facilities (88.3%).

Assessment of Postharvest Practices of Tuna Sold at the Honiara Fish Market in the Solomon Islands.

The study is aimed at assessing the impacts of postharvest handling practices on the quality and safety of tuna sold at the Honiara Fish Market (HFM), Solomon Islands. Two major approaches were adopted: (1) face-to-face interviews of 60 participants using questionnaires and physical observations of the supply chains and postharvest handling practices and (2) determination of time-temperature, quality index, histamine, and microbial load of tuna and contact surfaces. Sampling was conducted on both the wet season (WS) and dry season (DS), of which 36 samples from both batches of fresh tuna (FT) and brined tuna (BT) were analyzed. Three critical control points (CCPs) were identified in the supply chains of both FT and BT, where samples were obtained for scientific analyses. The average body temperature for WS tuna exposed for 9-10 h with low or no ice after catch was 3°C for FT and 15°C for BT, while DS samples were 26°C and 31°C for FT and BT, respectively. The quality index (QI) for WS showed a significant difference (P < 0.05) at 0 for FT and 8 for BT, while both DS showed a significant increase at 16 for BT and 5 for FT. Histamine levels for all the samples increased across the three CCPs, however with levels <50 mg/L, while microbial load for both seasons and for both samples were within the required specifications. However, contact surfaces for both seasons revealed high levels of microbial contamination. This study reveals that poor handling practices along the tuna supply chains of fish sold at the HFM were observed; however, all the tuna was safe for consumption when cooked properly.

Growth, Survival and Cost-benefit Analyses of Nutrient Rich Small Indigenous Species in Carp Polyculture System under Barind Area in Rajshahi District of Bangladesh

This study was conducted in Tanore upazila (sub district) of Rajshahi district, Bangladesh for a period of six months from July 2019 to December 2019. Investigation was carried into the economics of polyculture of Indian major carps with small indigenous fish species (SIS) Shing (H. fossilis), Magur (C. batrachus), and Pabda (O. pabda). The species composition was carps with shing (T1), carps with Magur (T2), carps with Pabda (T3) and only carps (T4). The economic feasibility of four different combinations was analyzed on the basis of the expenditure incurred and total return from sale price of fish in the local market. The net benefits per hectare from 6 months culture period for T1, T2, T3 and T4 were Bangladesh currency (Taka) as BDT. 635730.42, 805548.25, 580948.95 and 291489.07, respectively which largely reflected the gross fish production levels of 7680.42 ± 6.68, 8324.94 ± 16.64, 7581.13 ± 24.94 and 6344.55 ± 10.30 kg ha-1. However, carp polyculture with Magur (T2) provided highest benefit (BDT. 805548.25 ha-1), followed by carps-shing polyculture (BDT. 635730.42/ha-1), carps-Pabda polyculture (BDT. 580948.95 ha-1) and only carps (BDT. 291489.07 ha-1). BCR (Benefit Cost Ratio) was obtained highest in Carp-Magur polyculture, followed by carp-shing and carp-Pabda polyculture systems. So, Carp-Magur polyculture may be better as it has ensured better production of protein enriched SIS Magur and also economic point of view and this system is encouraging for rural people because they would get Magur regularly for consumption and carps as a cash crop.

Phenotypic, molecular detection and antibiogram analysis of Aeromonas Hydrophila from Oreochromis Niloticus (Nile Tilapia) and Ready-To- eat fish products in selected Rift Valley lakes of Ethiopia

BackgroundAeromonas hydrophila is a zoonotic bacterial pathogen that frequently causes disease and mass mortalities among cultured and feral fishes worldwide. In Ethiopia, A. hydrophila outbreak was reported in Sebeta fish ponds and in Lake Tana fishery. However, there is no to little information on the molecular, and phenotypical characteristics of A. hydrophila in Ethiopian fisheries. Therefore, a cross-sectional study was conducted from November 2020 to May 2021 in selected Ethiopian Rift valley lakes.ResultsA total of 140 samples were collected aseptically from fish (Muscle, Gill, Intestine, Spleen and Kidney) from fish landing sites, market and restaurants with purposive sampling methods. Aeromonas selective media (AMB), morphological and biochemical tests were used to isolate and identify A. hydrophila. Accordingly, the pathogen was isolated from 81 (60.45%) of samples. Among the isolates 92.59% expressed virulence trait through β hemolysis on blood agar media with 5% sheep blood. Moreover, 54 strains (66.67%) were further confirmed with Real-Time PCR (qPCR) using ahaI gene specific primers and optimized protocol. The highest (68.51%) were detected from live fish, (24.07%) were from market fish and the lowest (7.4%%) were from ready-to-eat products. Antibiogram analysis was conducted on ten representative isolates. Accordingly, A. hydrophila isolates were susceptible to ciprofloxacin (100%), chloramphenicol (100%) and ceftriaxone (100%). However, all ten isolates were resistant to Amoxicillin and Penicillin.ConclusionsThe study indicates A. hydrophila strains carrying virulence ahaI gene that were ß-hemolytic and resistant to antibiotics commonly used in human and veterinary medicine are circulating in the fishery. The detection of the pathogen in 140 of the sampled fish population is alarming for potential outbreaks and zoonosis. Therefore, further molecular epidemiology of the disease should be studied to establish potential inter host transmission and antibiotic resistance traits. Therefore, raising the public awareness on risk associated with consuming undercooked or raw fish meat is pertinent.
