Feeding trail experiments were conducted with Seven Experimental diets including One Control, Probiotics added and Five Bioflocs developed with different external Carbon sources for a period of 60 days with L. vannamei . Due to the addition of combinations of both Probiotics and Bioflocs, maintain rigorous control of all the Water quality parameters and provide protection and resistance to the Candidate species of culture i.e. all the Water quality parameters were ideally maintained. Intense mechanical aeration also favours degradation of toxic nitrogen and other compounds by the microbial community that additionally serve as a food supplement for shrimp, thereby Productivity rates were substantially increased. Therefore, BFT is an efficient alternative against pathogens, maintenance of water quality at optimum levels and enhances survival and growth of shrimp L. vannamei . The combined use of both Probiotics and Bioflocs in the present study not only maintains a good Water quality parameters and also Growth performance in L. vannamei .","PeriodicalId":14048,"journal":{"name":"International Journal of Fisheries and Aquatic Studies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139304221","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}

Ten samples of each species were collected from the study dams and they were subjected to single nucleotide polymorphic genotyping. Four SNPs primers, which consist of growth hormone and early growth response gene were utilized to amplified the DNA. Bands were generated from all the samples from the study dams in all the primers used for the amplification, which gives strong indications that, all the samples been genotyped are rich in both growth hormone and early growth response gene. Further-more, two samples from each species from the study dams were sequenced, then subjected to Bio-edit software to draw the evolutionary relationship tree. The samples were grouped into two main branches by the dendrogram in Bio edit software that draws the evolutionary relationship tree, the first branch are made up of all the C. gariepinus samples and the second branch comprises of all the H. bidosalis samples from the three dams, the two main groups show by the dendrogram reveals that both species are evolutionarily not very close to each other and this also give the reassurance of the two species belonging to different species and genera.","PeriodicalId":14048,"journal":{"name":"International Journal of Fisheries and Aquatic Studies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139293545","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}

However, this development is correlated with a variety of health problems observed in the most cultured fish in Senegal (tilapia and catfish). The objective of this study is to describe the clinical cases and lesions observed in tilapia (Oreochromis niloticus) and catfish (Clarias gariepinus), reared in fish farms in the Saint-Louis region. The study started with surveys followed by the description of clinical signs and macroscopic lesions observed on sick or freshly dead fish and then by bacteriological and histopathological examinations. Results from the investigations have highlighted, firstly, the risks of chemical or microbiological contamination related to the proximity of habitations to fish farms (environmental contamination), and secondly, the fluctuations of physico-chemical parameters and the degradation of water quality, feed quality and its storage conditions. The results showed that clinical cases are associated with lesions either localized on different parts of the body (fins, gills, eyes), or generalized to external and internal organs. Cases of malformations and swollen masses were also noted. Bacteriological analysis revealed the presence of Aeromonas hydrophila, in co-infection with Vibrio sp. Histology confirmed multiple necrotic, hemorrhagic and cystic lesions on skin and in other organs. The observed clinical cases are associated with the poor conditions of fish farming and of the local environment in the study area.","PeriodicalId":14048,"journal":{"name":"International Journal of Fisheries and Aquatic Studies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135638639","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}

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":null,"pages":null},"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}

This study consisted of evaluating the growth performance of Oreochromis niloticus juveniles fed with diets containing maggot flour. It was conducted at Burkina Faso from April to June 2022. 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. These diets were used to feed 3 batches of juveniles (5 g) in duplicate group for 60 days. Each batch consisted of 15 fish per happa of 1m 2 . After 60 days, results on zootechnical performances showed that juveniles of Oreochromis niloticus fed with diet 3 (36.70±9.32 g) had high growth performance compared to those fed with other diets (21.38 g±4.11 for diet 1 and 26.04 g±5.31 for diet 2).
