The research results showed that the best dosage to induce spawning in transgenic G4 mutiara catfish was found in treatment B (0.5 ml ovaprim/kg female and male broodstock weight and 0.5 ml HCG/kg male broodstock weight). After spawning, the broodstock pairs in treatment B showed the best results with an average relative fecundity of 85,103 eggs/kg broodstock, fertilization rate (FR) reaching 88.150%, hatching rate (HR) reaching 90.056%, and survival rate (SR) reaching 88.034%.","PeriodicalId":14048,"journal":{"name":"International Journal of Fisheries and Aquatic Studies","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79271184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, there has been a growing need to develop auto-feeder technologies that not only optimize feed utilization but also reduce labor costs and environmental impact. This abstract explores the various types of auto-feeder technologies that contribute to achieving feed independence in fish farming. The paper delves into three primary categories of auto-feeders: demand-based feeders, time-based feeders, and sensor-based feeders. Demand-based feeders employ advanced algorithms to dispense feed based on the fish's appetite, ensuring optimal feeding rates and minimizing wastage. Time-based feeders provide feed at pre-determined intervals, offering a more straightforward approach but requiring careful calibration. Sensor-based feeders utilize real-time data from environmental sensors, such as water quality parameters and fish behavior, to adjust feeding schedules and quantities accordingly. The abstract highlights the advantages and limitations of each auto-feeder type, considering factors such as feed conversion efficiency, growth performance","PeriodicalId":14048,"journal":{"name":"International Journal of Fisheries and Aquatic Studies","volume":"195 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75000648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data were collected from 600 fishermen (Paba, 200; Mohonpur, 200 and Durgapur, 200) through questionnaire interview and Focus Group Discussion (FGD). It was covered the main fishing communities in Rajshahi area. For data collection, three methods were used such as, personal interview, direct observations and use of PRA (Participatory Rural Appraisal) & FGD (focus groups discussion) tools regarding the fishermen information. Livelihood condition of fishermen were presented in terms of categories of fishermen, types of fishermen, age structure, educational status, family size, status of school going children, religion and marital status, housing condition, occupation, annual income, source of drinking water, sanitary conditions and credit access. It was found that 66-73% professional fishermen, 31-34% can signature, 49-57.50% small family (1-4), 87-92% Muslim and the rest were Hindus and others. Among the occupations of fishermen, only fishing was contributed 48-56.5%. The housing condition was Kacha 57.5-71% and annual income (<1) 1 lac (40.5-52.5%). Most of the fishermen used drinking water mainly Tube well (72.5-77.5%). Most of the fishermen depends on NGO for credit access. They face various problems such as low income, limited alternative income opportunities, inadequate credit system and lack of adequate medical services.","PeriodicalId":14048,"journal":{"name":"International Journal of Fisheries and Aquatic Studies","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76563820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
