Fish and Shellfish Immunology, 2011
The cytochemical, immunocytochemical and ultrastructural characteristics of leukocytes and thrombocytes in the peripheral blood of the fat snook (Centropomus paralellus) - a fish occurring in Brazil - were investigated. The cytochemical methods were performed to demonstrate four enzymatic reactions - o-toluidine-hydrogen peroxide, naphtol AS-MX ...

Fish and Shellfish Immunology, 2012
The objective of this work was to determine the hematological parameters and the phagocytic capacity of peritoneal macrophages of fat snook related to sex, stage of gonadal maturation and seasonal cycle. Blood was collected from 135 animals (78 females and 57 males) and used for determinations of: erythrocyte number, hematocrit, hemoglobin, erythrocyte

Feeding Habits of the Smallscale Fat Snook from East‐Central Florida
Transactions of the American Fisheries Society, 2014AbstractIn general, snook Centropomus spp. are opportunistic carnivores, feeding on fish and crustaceans, as shown by other studies on diets of centropomids in the western Atlantic Ocean. Diet studies for centropomids in Florida refer only to a description of the diet and the ontogenetic shifts in prey preferences of Common Snook C.

The effect of salinity on survival, growth and activity of digestive enzymes was evaluated in the fat snook (Centropomus parallelus). Juveniles of 76 days after hatching (0.35 g) were reared at 5, 15 and 35 ppt, in triplicate, for 50 days, at 0.6 fish/l.

Abstract High-quality live food is essential for reducing the frequent high mortality of newly hatched fat snook ( Centropomus parallelus ) larvae in hatcheries. Copepods, a rich nutrition source, cultivated with the microalgae Chaetoceros muelleri and Isochrysis galbana , were evaluated as food for 0–14-day-old larvae.

Journal of Experimental Marine Biology and Ecology, 2010
The tropical fat snook Centropomus parallelus is a species of recognized ecological importance and with a high economical potential for fisheries and aquaculture. The investigations of digestive tube morphology in association with their feeding abilities are fundamental to improve techniques for aquaculture feeding procedures.

Aquaculture, 2004
Fat snook (Centropomus parallelus) is a candidate species for aquaculture, but little work has been done towards commercialization of this species. A major constraint has been the inability to obtain consistent and predictable larval survival to metamorphosis, a consequence of high mortality during the first-feeding stage.

The objective of this work was to determine hematological parameters and the phagocytic capacity of peritoneal macrophages of the fat snook related to sex, stage of gonadal maturation and seasonal cycle. The hematological results did not show significant differences between males and females.

The effects of subchronic exposure to copper in fat snook (Centropomus parallelus)
Aquatic Toxicology, 2016Anthropogenic processes affect different communities through the release of contaminated effluents into water bodies. Copper can be found in the effluents of most industrial processes and in other effluent types. The fat snook Centropomus parallelus, found from Florida in the United States to southern Brazil, is of great economic importance and is used

Acute toxicity of nitrite in fat snook (Centropomus parallelus)
Marine and Freshwater Behaviour and Physiology, 2018AbstractOxidative stress and hypoxia responses in Centropomus parallelus exposed to three different concentrations of nitrite (0, 0.5, and 10 mg L−1) were evaluated. To determinate toxicity, we used enzymatic analyses and quantifications of oxygen consumption and opercular beats under conditions of normoxia and hypoxia.
