Nesse sentido, este estudo teve como objetivos apresentar um panorama da distribuição espacial e temporal de ovos e da assembleia de larvas no alto-médio Rio Jequitinhonha e relacioná-las às características dos ambientes existentes nessa área. As amostragens foram realizadas a cada três dias entre outubro/2014 e março/2015, em dois ambientes situados a montante e dois a jusante da barragem de Irapé. Foram coletados 2.916 ovos e 2.709 larvas de peixes, e a maior densidade de ovos e larvas foi capturada no trecho localizado a jusante da barragem, no entanto a fragmentação do Rio Jequitinhonha pelo barramento não influenciou na distribuição da assembleia de larvas de peixes situadas nem a montante nem a jusante do reservatório. Os ambientes situados a jusante da barragem, principalmente o tributário Araçuaí, parecem contribuir de forma importante para o sucesso reprodutivo das espécies de peixes da região.","PeriodicalId":505396,"journal":{"name":"Boletim do Instituto de Pesca","volume":"99 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141683504","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 this end, we used the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior Journal Portal, accessed through the Federated Academic Community, to search for data indexed between 2019 and 2023, in the following databases: Web of Science, Scopus, and CAB Direct. We used Brumadinho as the central keyword and linked to it 25 other secondary keywords, such as environmental disaster, fishermen, fish farmers, and Três Marias dam. To screen and select the results, we used Rayyan software and the Preferred Reporting Items for Systematic reviews and Meta-Analyses methodology. The search resulted in 990 articles, 61 theses, and 251 dissertations. Among them, only 26 articles, 19 theses and 66 dissertations were eligible as contributions to the topic, but very few reported the situation of fishermen and fish farmers. We concluded that there is a lack of information on the damage suffered by these people, and that more scientific studies and attention to this public are needed.","PeriodicalId":505396,"journal":{"name":"Boletim do Instituto de Pesca","volume":"95 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141682611","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}

These treatments also resulted in lower values of toxic nitrogen compounds and total suspended solids, suggesting a positive impact on water quality. Although these rates proved suitable, continuous adjustments are needed owing to variations in the BFT system.

The 28-day larviculture of Nile tilapia was carried out using 16 tanks with capacity of 15 L. The evaluations included water parameters, growth, survival, and gonad histology. The biofloc system displayed higher values for alkalinity, total suspended solids, settling solids, and turbidity compared to the clear water system (p < 0.05). Nevertheless, no difference (p > 0.05) was observed for in final weight, weight gain, feed conversion factor, survival, and growth rate between treatments. Then, tilapia post-larvae can be successfully reared in both biofloc and clear water systems without any negative impact on their zootechnical performance. Nonetheless, such results showed that tilapia can be reared in alternative systems, which can increase the production of this species.","PeriodicalId":505396,"journal":{"name":"Boletim do Instituto de Pesca","volume":"83 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141116449","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}

The parameters analyzed were fish-growth rate, hematological and immunological parameters, and intestinal microbiota. Also, fish were submitted to experimental infection challenge with Aeromonas hydrophila to evaluate the immune response. Nile tilapia juveniles (weight 8.86 ± 3.22 g) were used in the six treatments with four replicates, for 63 days. The treatments were: control basal diet; PAS-TR: basal diet plus 0.04 g·kg-1 of the probiotic (Bacillus cereus and Bacillus subtilis); MOS: basal diet plus 4 g·kg-1 of the prebiotic mannooligosaccharide, 4 g·kg-1 of the prebiotic Kappaphycus alvarezii. Two more diets were formulated by a combination of PAS-TR + MOS (4 +4 g·kg-1), and PAS-TR + KAP (4 +4 g·kg-1). For the challenge experiment, the fish were fed for 21 days, infected via intraperitoneal injection with A. hydrophila (1 x 106 UFC·mL-1), and the mortality rate was registered for 15 days post-infection. Results indicated the capacity of probiotic to remain in the gut for 63 days, and it was inhibited neither by autochthonous microbiota nor by prebiotics used. The feed additives tested for Nile tilapia did not cause a beneficial or adverse effect on growth or hematological variables. However, these treatments protected the fish from A. hydrophyla infection, proved by higher survival rate, and relative protection levels. We concluded that probiotic PAS-TR and prebiotics MOS and KAP, combined or not as symbiotics, may promote immune protection and reduce the mortality rate of A. hydrophyla infection.","PeriodicalId":505396,"journal":{"name":"Boletim do Instituto de Pesca","volume":"46 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140664927","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}
