Metabolic demand and growth of juveniles of Centropomus parallelus as function of salinity
Journal of Experimental Marine Biology and Ecology, 2005The effect of salinity and time of exposure on metabolism and growth of juveniles of fat snook, Centropomus parallelus, were investigated. Food conversion efficiency (FCE), specific growth rate (SGR), oxygen consumption, ammonia excretion rate and O:N (oxygen/nitrogen) ratio were assessed on groups of fat-snook (mean weight 2 g) acclimated for 15- and ...

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 ...

Anesthesia and transport of fat snook Centropomus parallelus with the essential oil of Nectandra megapotamica(Spreng.) Mez [PDF]
Neotropical Ichthyology, 2013 This study analyzed the chemical composition and anesthetic potential of essential oil (EO) of Nectandra megapotamica in fat snook (Centropomus parallelus). For the extraction of EO by hydrodistillation, leaves were separated in young (EO-Y) or old (EO-O), and the chemical composition of the EOs was determined by CG-MS.

Energy budget of juvenile fat snook Centropomus parallelus fed live food
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2006The fat snook Centropomus parallelus is a tropical estuarine species with importance for recreational and commercial fisheries and further aquaculture potential. Considering ingested energy (C) is channeled into growth (P), metabolic expenditure (R), excretion (U) and feces (F), a balanced energy budget was established for isolated and grouped juvenile

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.

Early weaning of fat snook (Centropomus parallelus Poey 1864) larvae
Aquaculture, 2006Abstract Feeding trials were conducted with fat snook larvae in an attempt to decrease the period of weaning without compromising larval growth and survival. Fat snook larvae of 30 days post-hatch (DPH; initial mean standard length = 9.6 ± 1.4 mm) were assigned to five feeding trials in which larvae received Artemia for 5, 10 and 15 days (co-fed ...

The use of anesthetic in fish farming is a traditional practice which aims to reduce the stress caused by transport and handling. However, anesthesia-induction protocols are commonly established and implemented without proper physiological/behavioral evaluation.

Sixty Centropomus parallelus juveniles were collected in March 2013 in two locations (Tromomó and Guaraguaçu) inside the Paranaguá estuarine complex, southern Brazil. The habitat residency and movement patterns of the individuals were inferred from Sr:Ca ratios and age recorded in the otoliths.
