The trial was laid out in a complete randomized design with eight feeding periods (0, 7, 14, 21, 28, 35, 42, and 49 days) and four replicates. A total of 240 fish (3.4 ± 0.3 g) were distributed into four aquariums and fed with the diet containing 32% crude protein, 15 MJ kg-1 gross energy, and 2.5% of CLA. Feeding CLA diet for 49 days resulted in the higher deposition of CLA, CLA isomers, and docosahexaenoic acid (DHA). The isomer c9,t11 was highly deposited than the t10,c12. Polyunsaturated fatty acids (PUFA), n-3, and n-6 increased with feeding period, whereas saturated (SFA), monounsaturated, and medium-chain fatty acids decreased. PUFA/SFA ratio, DHA/EPA, EPA+DHA, and thrombogenicity index increased linearly. Whereas atherogenicity index reduced, hypocholesterolemic/hypercholesterolemic ratio increased in quadratic effects over feeding time. No difference was observed for the n-6/n-3 ratio. Feeding A. altiparanae with 2.5% of CLA for a minimum of 35 days improves the fatty acid profile and provides a commercial product with good nutritional quality and functional benefits.","PeriodicalId":9062,"journal":{"name":"Boletim do Instituto de Pesca","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2021-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86767419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this residue is frequently discarded inappropriately. The possibility to obtain byproducts of higher added value is a reality. Inside this view attention must be given to processes for the recovery and extraction of target molecules. However, the high cost of processing these residues is one of the obstacles to their reuse; techniques that facilitate their handling and make the process cheaper are desirable, such as extraction in a two-phase aqueous system. Thus, the aim of this study was to extract collagenolytic enzymes from common snook (Centropomus undecimalis) using a two-phase aqueous system (polyethylene glycol/citrate), according to the 24 factorial design, using as variables: molar mass of PEG (MPEG), PEG concentration (CPEG), citrate concentration (CCIT), pH, still, considering purification factor (FP), partition coefficient (K), and yield (Y).

The oil of O. basilicum shows no antimicrobial activity, so its application would be ineffective; for such reason the subsequent tests were not performed. However, the essential oil of O. vulgare produced inhibition halo diameters ranging from 24.6 to 34.1 mm, on average, and the MBC ranging from 3.9% to 15.6%.

The food composition was studied related to the sex, size of the predator and seasonality. Of 359 stomachs sampled, 54 were empty due to regurgitation and presented a vacuity coefficient (Cv%) of 15.04%. In the analysis of diets between the sexes, it was possible to identify a greater participation of fish (30.43%) and Crabs (26.10%) for females, Shrimp (36.23%) and Organic Matter Not Identified (OMNI) (18.84%) in males. The diet showed spatial differences in length distributions.

This study analyzed the variation of fishery production against the seasonality of the water level of the Guaporé River (a tributary of the Madeira River) using information contained in the records of fishery landings in the area under study. In addition, two periods pre (2000 to 2008) and post (2009 to 2019) installation of the Jirau and Santo Antônio dams in the Madeira River were considered. Fish production in the period prior to damming indicated linearity (r2 = 0.41) which was inversely proportional to the water levels of the Guaporé River, with low fish production in the flood and high production during the low water phases. However, for the period after damming, these variables showed low correlation (r2 = 0.14). Among the fish species exploited, 35.13% presented significant differences (p <0.05) between the production values for the periods before and after installation of the dams. Therefore, the results showed significant differences between the values of fishery production by species and phases of the hydrological cycle of the Guaporé River, which occurred in the periods pre and post damming of the Madeira River, which indicates that the hydroelectric dams have negatively impacted the fish stocks of this region. The information contained in this study is useful and serves as a basis for coherent decision-making, since it aids in the sustainable management and monitoring of fish stocks in the Madeira River Basin.","PeriodicalId":9062,"journal":{"name":"Boletim do Instituto de Pesca","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75178995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
