A total of one hundred and thirty four (134) samples of fish species were sampled monthly from artisanal fishers’ catches at exactly 6:00am at the lake’s landing site. The specimens comprises of 69 and 65 male and female respectively. The major fishing methods employed by fisher folks for collecting the specimens were cast netting and set netting. The results from this study indicated a negative allometric growth pattern for LWRs, LLRs and LFRs with highest exponent, b value of 1.157 for the females, and 1.090 in LLRs and 0.965 in LFRs all for the males. All LWRs, LLRs and LFRs were significant (p< 0.05) with most R2 values > 0.8 whereas the mean condition factor, K, for all sexes was ranged from 0.75 to 0.88 which indicated that the fish species exhibited compromised well-being within the examined lake. Therefore, this present research was crucial in addressing the information void and supplying data for the effective management and conservation of the studied species within the lake system and also suggested the need for additional investigation to compare the periods of the year characterized by wet and dry seasons.","PeriodicalId":14048,"journal":{"name":"International Journal of Fisheries and Aquatic Studies","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135389025","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}

To test the effect of maggot flour on the growth of O. niloticus , 3 diets noted as R1, R2 and R3 were made of 100% fishmeal, 50% fishmeal + 50% maggot meal and 100% maggot meal respectively.

Bangladesh is producing more catfish since they are exceptionally resilient and can tolerate harsh weather conditions and unstable habitats. The aims of the research were to assess fish farmers' knowledge of using artificial feed for catfish culture and to identify the variables affecting their knowledge level. Thus, the research was conducted in three villages of Gauripur upazila (sub-district) of Mymensingh district. In-person interviews were conducted with 80 randomly chosen catfish farmers. According to the findings, the vast majority of respondents (63%) had medium-level and 32% had high and 5% of farmers found which have a low level of knowledge on using artificial feed for catfish culture. Formal education, fish farming experience, farm size, annual income, social mobility, communication exposure and training received were positively and significantly correlated with the knowledge of the respondents. Multiple linear regression analysis confirmed that formal education, communication exposure, and training received significantly influenced fish farmers’ knowledge. High cost of fish feed, inaccessibility of good quality fish feed and lack of proper training were identified as the major problems faced by the fish farmers. In connection to these difficulties, development agencies such as Department of Fisheries, Ministry of Fisheries and Livestock, Bangladesh Fisheries Research Institute, relevant non-government and private organizations should take appropriate action like regular need based training, method demonstration, result demonstration, field day, other extension activities to increase the fish farmers’ knowledge on using artificial feed for catfish culture.","PeriodicalId":14048,"journal":{"name":"International Journal of Fisheries and Aquatic Studies","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135588969","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 has been observed that the family size of 59% of fishers was medium, consisting of 5-6 members. Most of the fishermen belongs to the age group 31-40 years old, represented by 83% Muslim. About half of the fishermen are illiterate and only sign their names. Most of the fishers (55%) have house made of mud walls with tin roofing, connected to electricity supply. The sanitation condition of the study is not up to the mark, as 63% of fisher communities are dependent on non-MBBS village doctors. The majority of them have medium to low income.
