Acceptance of farmed African catfish in Egypt: addressing consumer concerns and marketing challenges

African catfish farmers used animal waste as feed to reduce production costs, a practice that raised concerns among consumers, causing them to avoid it. Consequently, this study aimed to explore factors that influenced the acceptance of farmed African catfish. The data survey involving 2294 participants from Egypt was analyzed using descriptive statistics and the chi-square test. The results indicated that 67% of participants abstained from consuming it, while 2.30% consumed it regularly. The chi-square test revealed significant consumption pattern variations (p < 0.05) based on most demographic factors. Entirely, 43% were uninformed about the nutritional value, market availability, and the potential impact of using aquafeeds on pricing. About 55–57% lacked information on feeding practices, had quality concerns, viewed catfish consumption as a health risk, and were unaware of its prices. Additionally, 68% were worried about pollution, and 76% found the available information insufficient. The main reasons for this challenge lie in consumers’ health, religious, and psychological concerns. To address this, we propose a targeted marketing strategy focusing on improving safety and quality through safe and cost-effective aquafeeds. This involves requiring farmers to obtain quality certifications and adhere to best management practices, adding value to the product, and transparent communication with consumers to provide them with reliable information about cultivation practices and the nutritional value of African catfish. Effective collaboration among key stakeholders in implementation, efficient sector management, establishing an activity licensing system, and prohibiting current feeding practices will enhance sustainable demand and reverse the declining production trend of this promising species.

Characterization of specialist European catfish anglers in southern Germany: Implications for future management

The European catfish (Silurus glanis) is a large apex predator native to Eastern Europe. Increasing populations within and outside the species’ native range in recent years, and its popularity with recreational anglers are fueling discussions about appropriate management. To understand the motivations of anglers and their views on different management strategies, an internet survey was conducted in southern Germany. The results showed that catfish anglers differ in several aspects from those targeting other species. For specialists, catfish fishing is a central part of life, and they invest significant time and money to catch trophy sized fish. Most catfish anglers think that their targeted species has no negative effect on the local fish community and practice catch and release, despite this practice being illegal in Germany. Large catfish are often released under the misapprehension that they are inedible. The findings of this study suggest that new fishery management approaches are needed in order to mitigate the impact of European catfish in southern Germany. A co-production approach actively incorporating anglers’ perspectives will be essential in implementing education and incentives for catfish consumption alongside other aspects of fisheries management.

Increasing Public Awareness of the Importance of "Gemari" (Love to Eat Fish) Through Mentoring Catfish Cultivation and Processing

Catfish is one type of freshwater fish that is much loved by the people of Indonesia. In addition to its delicious taste and easy to process, this type of fish also has a lot of nutrients in it that are good for body health. Catfish farming is a maintenance activity for catfish enlargement from small in size (fry) to consumption size. Catfish farming is one of the efforts to provide food needs as a source of protein. Protein sources from fish are increasing day by day, along with increasing public awareness about the importance of catfish's nutritional content. The method used in this community service activity is by providing counseling, handing over catfish seeds, and assisting catfish processing as a health promotion medium. The results of Community Service activities regarding catfish farming, processing methods, and understanding of the high nutritional content in catfish can increase family interest in catfish consumption through fondness for eating fish.

Environmental Health Risk Analysis of Copper Exposure to Catfish Commonly Consumed By People in Ulak Jermun Village, Ogan Komering Ilir

Catfish cultivated in rivers can be contaminated by heavy metals such as copper (Cu) which come from activities around the river. Copper exposure through the consumption of catfish will be harmful to health. This research aim to analyze the public health risks due to catfish consumption in Ulak Jermun Village, Ogan Komering Ilir. The design of study was cross sectional using the Environmental Health Risk Analysis method. The research respondents were 113 people with 5 samples of catfish taken from the river where the fish were cultivated.

There were no respondents with RQ value &gt; 1 for realtime non-carcinogenic health risks, but 11 people (9.7%) of respondents with RQ value &gt; 1 for non-carcinogenic health risks in a lifetime. Meanwhile, for realtime carcinogenic exposure 34.5% had ECR values &gt; 10-4 and 100% of respondents had ECR values &gt; 10-4 for carcinogenic effects in lifetime. The conclusion was the people of Ulak Jermun are at risk of experiencing carcinogenic diseases due to copper exposure with the largest percentage of people aged&gt; 32 years, female, and weighing ≤ 57 kg.

Application of Dry Probiotic Rabal to Increase Growth Performance of Catfish (Clarias sp.)

Catfish have become an important contributor to fish production in Indonesia. Catfish consumption in Indonesia always increases every year. To meet the demand for catfish consumption, it was carried out with an intensive aquaculture system. However, the high cost of feed has been identified as a significant constraint in catfish farming. Efforts to increase catfish growth are needed to reduce feed costs, one of the efforts is by probiotic supplementation through the feed. This study was carried out to determine the best dose of probiotic rabal dried addition to increasing catfish growth. The experiment used four treatments and three replications. Probiotic rabal dried doses: 0% of feed (A)/feed (control), 5% of feed (B), 10% of feed (C), and (D) 15% of were used as treatment. The feed was given ad-satiation with a frequency of feeding three times a day. Observations were made for 45 days. The results indicated that the B treatment of 5% of feed gave the best absolute weight growth and feed conversion ratio. While catfish fish survival rate was not significantly different on all treatments.

Community Service Program, especially the Appropriate Technology Application Program (PPTTG) in the village of Curug, Gunung Sindur District, Bogor Regency, which involves the community, especially catfish farmers, in an effort to increase community economic empowerment and marketing of catfish farming crops. Since the occurrence of Covid-19 has become a problem and has had an impact on the business activities of catfish farmers in marketing the catfish harvest because the amount of catfish consumption needs has decreased due to the decreasing purchasing power of the people around the village of Curug, the price of catfish feed has tended to rise so this condition has add to the burden of new problems for the community. PPTTG program help catfish farmers in village Curug as partners to be able to market their catfish harvest through direct sales and digital (online) marketing so that economic income increases and is able to buy catfish feed at a reasonable price, provide training and business assistance. catfish. The solutions offered in dealing with partner problems in developing catfish marketing through websites and internet marketing 4.0, making dumplings from catfish, help establish a special cooperative for catfish farmers so that catfish farmers have a formal organization that can assist in capitalizing catfish farmer members, providing tools for catfish production. The results of the PPTTG are the establishment of cooperatives for catfish farmers, diversifying catfish products such as dumplings, online marketing of catfish (marketing strategy 4.0), and owning the copyright and production brand rights so that catfish farmers can run catfish farming more increased. As for the sustainability of this program, it is hoped that catfish farmers in the village of Curug can continue to maintain the potential of catfish business and increase economic income

Food habits of wintering double-crested cormorants in the Mississippi Delta

Given its ubiquity, it is not surprising that agriculture, including finfish aquaculture, contributes to food webs worldwide and is used by numerous wildlife for foraging and meeting other needs. Double-crested Cormorants (Phalacrocorax auritus) impact United States commercial aquaculture and are considered the primary avian predator in catfish (Ictalurus spp.) aquaculture facilities in the Mississippi Delta. Recent changes in aquaculture practices, regulatory policies, and decreased overall hectares in production prompted this study that assessed cormorant consumption of catfish in relation to their night roosts through surveys and diet analysis. Cormorants were collected from night roosts from October through April 2016–2018 (n = 69 collections). On average, catfish constituted 33% of a cormorant's overall diet, which is less than reported in previous studies. There was no statistical difference between consumption of channel (I. punctatus) and hybrid catfish (I. punctatus x I. furcatus) based on biomass estimates, and the greatest consumption of catfish occurred in the months of February and March. The best fit model for predicting catfish consumption was the cubic polynomial function of the area of catfish aquaculture within a 30.6 km forage buffer of a night roost. Our findings will inform wildlife managers about relationships between cormorant night roost locations and consumption of catfish and aid decision making with respect to cormorant management. Despite cormorants having shifted consumption to naturally occurring fish species associated with changes to aquaculture, aquaculture remains an important part of regional food webs.

Susceptibility of Hide Beetle, Dermestes maculatus (De Geer) [Coleoptera: Dermestidae] to Powder and Extract of Two Species of Capsicum Fruits on Smoke-Dried Catfish, Clarias gariepinus (Burchell) [Pisces: Clariidae

Meat consumption is expensive and highly blood pressure prone amongst elderly Nigerians. In lieu of this, smoke-dried catfish consumption becomes a better alternative in reducing cholesterols that cause high blood pressure amongst elders. However, the nutritional values and health benefits of smoke-dried catfish have greatly reduced during postharvest due to hide beetle, Dermestes maculatus infestation. Susceptibility of hide beetle, Dermestes maculatus to Capsicum annum, and Capsicum frutescens fruits onsmoke-dried catfish, claria gariepinns were investigated in the laboratory at mean temperature and relative humidity of 29.6oC and 76.8%, respectively. Capsicum fruits powders were admixed at 2g, 4g, 6g, 8g, and 10g/50g of smoke-dried catfish while extracts were tested at concentrations 2%, 4%, 6%, 8% and 10% for mortality, adult emergence, progeny inhibition, and weight loss effects. Capsicum frutescens powder was more toxic to D. maculatus larvae. It achieved 100% larvae mortality throughout the period of exposure at dose 10.0g. Capsicum frutescens was also found to be more toxic than C. annum to D. maculatus adult that caused 82.50% mortality at concentration 10.0 g within 24 h of application and were significantly different (P < 0.05) from all other treatments within the same period. The two plant powders were able to prevent adult emergence except for the powder of C. annum which recorded 32.50% adult emergence at concentration 2.0 g and was significantly different (P<0.05) from other treatments. A similar trend of results was observed on the toxicity of fruits extracts to D. maculatus larvae and adults. Capsicum frutescens was more lethal to D. maculatus larvae. The plant materials significantly reduced adult emergence and weight loss when compared with the control experiment. Capsicum annum and C. frutescens offered an effective protection against infestation and damage cause by D. maculatus on smoke-dried fish.

PELATIHAN PEMBUATAN PROBIOTIK PADA PETANI PEMBUDIDAYA IKAN DESA PEUNAGA PAYA KECAMATAN MEUREUBO KABUPATEN ACEH BARAT

The Increasing of community needson catfish consumption in West Aceh district is making it more diffucult for catfish farmers tomeet the need. Peunaga Paya Village as one of the catfish producing villages in Meureubo District constrained in meeting the market demand for this product. Not optimal production was one of the causes for that problem.This is due to their knowledge and ability about catfish farming techniques was lacking so their current culture management was still not good. In addition, fish farmers still use conventional technology so they have not understood the importance of adding nutrients in fishfeed to accelerate the harvest period with optimal results. So far, the obstacles they faced are using traditional technology due to lack of partners knowledge and ability, fish susceptible to disease, cultivated fish often experience decreased appetite, poor of water quality, and slow fish growth rate so the harvest time more longerand the cost production increases. In order to solve the problems, it is implemented the community service activities by giving counseling about the proper fish farming techniques and the practice of making probiotics as an additional nutrient to fishfeed withcheap and easy to find ingredients.

Designing of Closed-Loop Supply Chain on Dry Land-Based Catfish Aquabusiness in Gunungkidul: A System Dynamics Approach

Dry land-based catfish fishery is one of the promising rural aquabusiness in Gunungkidul, Yogyakarta. There are several problems in this business, for example, supply-demand balancing, calculation accuracy of production capacity, and equitable profit distribution to each stakeholder. This research aimed to design a closed-loop supply chain of dry-land catfish industrial-fishery model by employing the system dynamics approach. Powesim Studio 7 coupled MINITAB 14 was applied to measure the robustness of the supply chain management system, to predict optimum production capacity, and to balance profit distribution. A financial analysis was also performed to determine business feasibility. Three scenarios of price were created by considering the predicted trend of catfish consumption and formulated three alternative prices by appraising the juvenile fish production, aquaculture practices, local feedstock manufactured by farmers, and fish-by products distributed by small-enterprises. Those consideration units were constructed of four observed models. The highest profit to stakeholder was obtained by scenario III that was directed to increase the juvenile fish price to Rp 240/fish, consumption-sized fish at the price of Rp 18,000/kg, fish-by product at the price of Rp 150,000/kg, and local feed at the price of Rp 9,000/kg. According to financial analysis, the four subsystems in dry land-based catfish aquabusiness were all feasible by BCR&gt;1; PP was 5-9 years, NPV&gt;0, PI&gt;1, and IRR&gt;15%/year. The implementation of the system required synergetic action among policymakers, farmer cooperative, and local innovation centers.

Bacteriological evaluationofraw Catfish (Clariasgariepinus)

Fish is a worldwide distributed food commodity regarded an inexpensive source of protein especially in the developing countries like Egypt; it provides a good balance of protein, vitamins and minerals. In Egypt, catfish consumption is increased especially with its availability with reasonable price after expanding of its intensive farming; however, bacteria occur naturally on the skin, in the gut and in the slime of living fish without causing harm in healthy fish, unfortunately, it may migrate to its musculature associating with improper transportation, storage, and handling rendering it of potential hazards to consumers and wholesome of fish for consumption; therefore this study aimed to bacteriologically evaluatefifty random samples of catfish collected from retail and supermarkets in Benha city, Qalubiya governorate, Egypt. Results revealed that, the mean values of aerobic plate count (APC), total enterobacteriaceae, and total coliforms countswere 9.74×105, 3.25×103, and 2.35×103CFUg, respectively; Escherichia coli (E. coli), Salmonellae, andYarseniaenterocoliticacould be detected in 18, 6, and 10% of examined samples, respectively, which went in further serological identification. The study indicated that the hygienic status of raw catfish is strongly related to source of collection, conditions of storage and handling; and recommended following proper hygienic properties of rearing, transportation, storage and handling.

Status of trace metals in smoked Clarias gariepinus cultured in earthen pond in Lagos state, Nigeria

Catfish consumption has risen over the last 2 decades with its popularity more pronounced in a cosmopolitan, commercial and industrial region like Lagos state. However, there is a need to measure the level of anthropogenic induced impacts on the safety level of fish production within this environment for human consumption. This research determined the level of trace metals bioaccumulation within the three senatorial districts of Lagos state. A total of nine (9) fish farms (three from each senatorial district) operating earthen ponds were randomly selected. Water samples from the farms were also collected and analyzed for heavy metals. Fish samples were smoked before analysis. The trace metals such as chromium, cobalt, iron, lead, aluminum and copper and manganese was analyzed using Atomic Absorption Spectrophotometer. The result of the trace metals were 0.07 – 0.13 mg/kg (lead), 0.01 – 0.02 mg/kg (chromium), 6.75 – 7.77 mg/kg (iron), 3.05 – 3.89 mg/kg (manganese), 0.05 – 0.07 mg/kg (copper), 0.00 – 0.01 mg/kg (cobalt) and 0.00 – 0.01 mg/kg (Aluminum). Statistically, there is no significant difference (P>0.05) among the various locations except for aluminum. The trace metal levels were below the tolerable or allowable level for fish food as recommended by Food and Agricultural Organization or World Health Organization, Median international standard, European Union, United State Environmental Protection Agency and Water Pollution Control Legislation for fish food. The detection of lead above standard in the water suggests the need for frequent monitoring of the water quality and fish food to prevent possible toxicity that could arise from the consumption of the fish food from the study area.

Arsenic, selenium, and metals in a commercial and vulnerable fish from southwestern Atlantic estuaries: distribution in water and tissues and public health risk assessment.

The anadromous catfish Genidens barbus is a vulnerable and economically important species from the Southwestern Atlantic Ocean. Concentrations of As, Co, Fe, Se, and Zn were determined in water and muscle, gill, and liver of catfish from two southwestern Atlantic estuaries (Brazil and Argentina) and health risk via fish consumption was evaluated. High spatial variability was observed in the metals, As, and Se distribution for both estuaries. Considering all tissues, element concentrations (mg/kg, wet weight) were As = 0.41-23.50, Co = 0.01-2.9, Fe = 2.08-773, Se = 0.15-10.7, and Zn = 3.97-2808). Most of the trace elements tended to be higher in Brazil than in Argentina, except for Co, Fe, Se, and Zn in liver and Fe and Co in muscle and gill, respectively. Arsenic accumulation order was muscle > liver ≥ gill. Only As (muscle) was above the maximum recommended by international guidelines at both estuaries. The target hazard quotient ranged from 0.10 to 1.58, suggesting that people may experience significant health risks through catfish consumption. Supposing that the inorganic/toxic As ranged between 1 and 20% of the total, the recommended maximum intakes per capita bases were 6.1-95 and 8.4-138kg/year (wet weight) for Brazil and Argentina, respectively. Carcinogenic risk for As intake was within the acceptable range but close to the recommended limit (> 10-4). These results highlights the importance of quantifying the As species in catfish muscle in order to generate more reliable risk estimates.

Radiological risks assessment of 238U, 232Th and 40K in fish feeds and catfish samples from selected fish farms in Ado – Ekiti, Nigeria

Fish is one of the major sources of protein in the diet of the vast majority of people living in Ekiti State and Nigeria in general. This study was carried out to ascertain the possibilities of radionuclides pollution due to catfish consumption in the study area. The activity concentrations of radionuclides were determined in catfish and fish feeds using gamma spectrometry method. Committed effective doses were inferred for adults and children of age 10 from the activity concentrations of 40K, 238U and 232Th in catfish. The results show that the annual committed effective doses for adults and children were all lower than the recommended 1.0 mSv y−1 limit for memebers of the public. This shows that the radiation dose incurred from the ingestion of the fresh catfish samples pose no significant health risks to the population from a radiological point of view.

PEMANFAATAN AZOLLA SEBAGAI SUMBER PAKAN PADA BUDIDAYA SISTEM GANDA AZOLLA-LELE

&lt;div class="WordSection1"&gt;&lt;p&gt;&lt;em&gt;Catfish farming is strongly influenced by the high price of feed, while azolla is a water fern that has a high nutritional value, can develop quickly and preferably by catfish as feed. The research aims to obtain the most appropriate combination treatment of Azolla inoculum dose and catfish seed size in dual system Azolla - catfish, which is able to provide the highest catfish yield. The experiments were performed in catfish ponds in completely randomized design (CRD) two factors, i,e azolla inoculum doses (250, 500 and 750 gm&lt;sup&gt;-1&lt;/sup&gt;) and head circumference size of catfish seed (3, 4 and 5 cm). Dose of catfish seed is 2,000 head / m&lt;sup&gt;2&lt;/sup&gt;. Variables observed were azolla fresh weight and catfish fresh weight at harvest. Azolla inoculum and catfish seed deployed together in catfish ponds and feeding with concentrate feed for one month. Azolla and catfish harvesting is done on the same day using a sieve. Once drained, Azolla and catfish were weighed separately to determine the severity. Data were analyzed by F test at the level of 95%, followed by Duncan's multiple range test (DMRT) if any significance influence. The results showed that the higher the azolla inoculum number, the higher azolla yield. The larger the size of catfish seed the higher catfish consumption to Azolla. Catfish seed size more than 4 cm will cause an imbalance between the speed of consumption of Azolla by the catfish and the azolla growth rate, so that Azolla be devoured by catfish.&lt;/em&gt;&lt;/p&gt;&lt;/div&gt;

Influence of Processing Parameters on Microbial Load, Sensory Acceptability, and Mineral Contents of Dehydrated Catfish (Clarias gariepinus)

ABSTRACTCatfish was dehydrated to improve handling using Response Surface Methodology for experimental design. Brine concentration (%), brining time (min) and drying temperature (°C) as processing parameters interacted in different combinations. Influence of processing parameters on microbial load, sensory acceptability and mineral contents of dehydrated catfish was investigated. Data analysed using regression, ANOVA and average ranking grade. Low total viable and fungi counts (ranged 1.0x103-3.0x103 CFU/g) with no detection of pathogen indicates safety for consumption. Brine concentration significantly (p < 0.05) influenced the texture of catfish. The model accounted for only 29.36% of the total variation (R2 = 0.2936). The 6% brine, 90 min and 110°C treatment, significantly improved the overall-acceptability. Calcium content (ranged 19.60–52.60 mg/100 g) was significantly higher which could improve the nutrient intake to facilitate development and maintenance of strong bones. Knowledge about safety, acceptability and nutrient content of dehydrated catfish could contribute positively to reshaping decision-making about catfish consumption.

Introduced Flathead Catfish Consumptive Demand on Native Fishes of the Upper Gila River, New Mexico

AbstractPredation by nonnative fish is often cited as a leading cause of declining native fish populations, but quantifying these negative interactions is difficult. Bioenergetics modeling provides a tool to estimate consumptive demand of nonnative species and to identify those that pose the greatest threats to native biota. We used bioenergetics modeling to estimate the consumptive demand of Flathead Catfish Pylodictis olivaris on native fishes in the upper Gila River, New Mexico, across an elevational gradient. Model results were coupled with measured densities and size structure of Flathead Catfish populations, as well as water temperatures, to predict its predatory threat. Potential consumption was highest at lower elevation sites because of higher water temperatures, but actual consumption was highest at mid‐elevation sites because of the prevalence of larger individuals there. Potential annual consumptive demand of Flathead Catfish on native fish across our nine sampling sites ranged from 0.0 to 3.1 g/m2, which exceeded native fish productivity at one site. Our results identify areas within the upper Gila River where introduced Flathead Catfish consumption is likely to negatively impact native fish populations.

Omega-3 and Omega-6 Fatty Acids Potential of Smoked and Boiled Catfish (Clarias Gariepinus)

Boiled and smoked catfish (Claria geriepinus) were evaluated in order to know omega-3 and omega-6 fatty acids potential of these processed fishes. Samples were analyzed for their fatty acids using modified AOAC methods and gas chromatography (gc). Findings shows that linoleic (Ω-6), alpha-linolenic (Ω-3) and gamma-linolenic were significantly higher in boiled catfish and covered respectively 9.0351e-7, 9.56501e-5 and 2.76276e-5 area when subjected to gas chromatography compared to the smoked cat fish. Also, both saturated and unsaturated fatty acids were present in appreciable amount in the processed samples. Therefore, catfish can serve as a potential source of essential fatty acids to human nutrition particularly in Nigeria where cat fish consumption is growing popular.
