The Funil Reservoir receives a large amount of xenobiotics from the Paraíba do Sul River (PSR) from large number of industries and municipalities in the watershed. This study aimed to assess environmental quality along the longitudinal profile of the Paraíba do Sul River-Funil Reservoir system, by using biomarkers and bioindicators in a selected fish species. The raised hypothesis is that Funil...

The effect of biofloc (BFT) and clear water (CW) at low (ls) high-water salinity (hs) in wild juveniles Penaeus setiferus were evaluated. Four treatments implemented: hsBFT, lsBFT, hsCW, lsCW. After 45 days, final weight (FW), gain (WG), hepatosomatic index (HSI), survival rate (SR) Antioxidant activity muscle hepatopancreas measured: superoxide dismutase (SOD), catalase (CAT), glutathione-S tr...

Measuring fish population responses to climate change requires timely ecological information, warranting innovative approaches data collection in fisheries research and management. Fourier transform near-infrared (FT-NIR) spectroscopy is a promising tool efficiently cost-effectively obtain multiple types of including physiological health energetics that can provide indicators stock status envir...

In spite similarity size mass values caught different bays there has been found regularity size: Balaklavskaya Bay > Kruglaya Streletskaya Bay. indexes gills liver Scorpaena po...

Fish diets are important indicators of ecosystem change. This aspect the ichthyofauna coast Argentine Islands has been insufficiently studied in comparison with other regions. article presents results dietary and somatic parameters dominant species Notothenia coriiceps depending on point, depth season catch. The sample was collected between February 2006 2007. In year study, N. coriiceps, Trema...

This study evaluated survival, growth performance, digestive enzyme activities, intestinal histology, and antioxidant activities of the Pacific white shrimp (Litopenaeus vannamei), which were fed with five different diets, containing 0%, 25%, 50%, 75%, 100% fresh black soldier fly larvae (BSFL), respectively, to replace commercial feed at an equal wet weight. The cultured experiment was lasted ...

The European sardine’s condition is reflected in its reproductive potential, and therefore, status as a fishery resource. These values depend on the stock’s distribution resource availability, which highly determined by environmental characteristics. Sardines from productive Gulf of Trieste (in North Adriatic), located northernmost section most septentrional Mediterranean sub-basin sardine expl...

This study evaluates the influence of dietary vitamin A on growth performance, antioxidant capacity, and lipid metabolism Eriocheir sinensis juveniles (3.95 ± 0.12 g) fed different levels. Crabs were with four diets, including normal (7%) devoid (0 IU/kg, NL-VAD), supplement (6000 NL-VAS), high (13%) HL-VAD), HL-VAS) for 8 weeks. The significant interaction between level was found in weight gai...

This study evaluated the status of well-being wild Nandus nandus in Kawadighi Haor through morphometric and gastrointestinal indices local people’s perceptions. Basic macroscopic morphology tract (GIT), viscera somatic index (VSI), hepatosomatic (HSI), condition factor (K), length–weight relationships, gut histology were analyzed from regular commercial catch. The GIT includes a tube-like esoph...

Two feeding trials were conducted to evaluate the influence of dietary curcumin level on fish meal replacement with poultry by-product (PBM) in a largemouth bass (Micropterus salmoides) diet. In trial I, reference diet (R) contained 400 g/kg meal, and PBM replaced 60 80% (P16 P8). II, containing 80 (P8) served as control (C), was added at 5000 10000 mg/kg (C5 C10), respectively. Replacement sig...
