Fish larvae behavior is an action or activity carried out by fish larvae to fulfill their life needs. Several factors such as population density, level of food availability, air temperature, air quality, and lighting can affect the behavior of fish larvae. The nutritional needs of larvae are higher than adult fish, because nutrients are needed not only for activity and maintenance, but also for growth. The behavior characteristics of fish larvae towards various types of feed can vary depending on the fish species, developmental stage, and the type and quality of the feed given. The purpose of this article is to understand how the level of food availability has an impact on the destruction of life and growth of fish larvae. This preparation uses a literature review with a narrative literature review method. The results of this article can be seen in the importance of food availability in the life cycle of fish, especially in the early stages of the larvae.","PeriodicalId":14048,"journal":{"name":"International Journal of Fisheries and Aquatic Studies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77486646","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":null,"pages":null},"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}

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.

The study describes the available fishing gears and crafts used in Chalan beel, Bangladesh. The study was carried out in 7 spots under 5 upazilas of 4 districts such as Atrai upazila (Nawgaon), Singra upazila, Gurudaspur upazila (Natore), Chatmohor upazila (Pabna) and Tarash upazila (Sirajganj), respectively. Eye observation and interview method were applied for the data collection. During the study period, 20 different types of fishing gears were observed. Fishing gears including 9 types of net (Ber jal, Khepla jal, Puti jal, Thela jal, Current jal, Moi jal, Veshal jal, Suti jal and Dharma jal); 4 types of trap (Kholson, Doair, Polo and Vair); 3 types of wounding gears (Koach, Ek kata and Angta) and 4 types of hooks and lines (Chip borsi, Nolborsi, Daun borsi and Jiala) were found. Another 2 types of fishing method were also recorded. Among the available nets in the study area it was recorded that maximum length was 363.33±109.70 fit (Ber jal) and minimum length was 15±5 fit (Dharma Jal). It was also recorded that the maximum and minimum breath were 106.67±15.27 fit (Suti jal) and 2.5±0.5 fit (Puti jal), respectively. Mesh size of net varied from 3±0.5cm (Suti jal) to 0.83±0.52cm (Thela jal). Among the traps maximum length was 2.5±0.5 fit (Kholsun) and minimum length was 1.83±0.28 fit (Vair). Small Indigenous Species (SIS) was mostly caught by the trap with few exception and carnivorous fishes are mainly caught by the fishing hooks and lines. When water level becomes low, wounding gears were used for fishing large size fishes during heavy flood. In Chalan beel 5 crafts (Kosa nauka, Bhot nauka, Jaila nauka, Konai dingi and Vela) were observed. Cost benefit ratio of studied fishing crafts was also calculated. The highest Cost Benefit Ratio (CBR) is 1:0.92 (for Vela). Several problems were found which are responsible for the loss of fish diversity of Chalan beel. Among them, over fishing and use of illegal (Current jal), destruction fishing gears, fishing by blocking (Bana) the migration paths of fishes, excess katha fishing and fishermen caught brood and fry fishes indiscriminately.","PeriodicalId":14048,"journal":{"name":"International Journal of Fisheries and Aquatic Studies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81039904","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}
