The effects of subchronic exposure to copper in fat snook (Centropomus parallelus)

Aquatic Toxicology, 2016
Anthropogenic 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, 2018
AbstractOxidative 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.

Hematological parameters and phagocytic activity in fat snook (Centropomus parallelus) bred in captivity

Fish & 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

Cytochemical, immunocytochemical and ultrastructural observations on leukocytes and thrombocytes of fat snook (Centropomus parallelus)

Fish & 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 ...

Morphocytochemical, immunohistochemical and ultrastructural characterization of the head kidney of fat snook Centropomus parallelus

Journal of Fish Biology, 2011
This study characterized the structure and the morphocytochemical, immunohistochemical and ultrastructural aspects of the head kidney (HK) of the fat snook Centropomus parallelus. The HK is enclosed by a thin capsule of connective tissue, from which fine trabeculae originate and branch into the interior of organ. In the parenchyma, there are aggregates

Benzocaine-induced stress in the euryhaline teleost, Centropomus parallelus and its implications for anesthesia protocols

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2018
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.

Habitat residency and movement patterns of Centropomus parallelus juveniles in a subtropical estuarine complex

Journal of Fish Biology, 2016
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.

Metabolic demand and growth of juveniles of Centropomus parallelus as function of salinity

Journal of Experimental Marine Biology and Ecology, 2005
The 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 ...

A review of spawning induction, larviculture, and juvenile rearing of the fat snook, Centropomus parallelus

Fish Physiology and Biochemistry, 2008
The fat snook, Centropomus parallelus, is a commercially valuable marine fish species with potential for aquaculture. This paper describes the development of technology for mass production of fat snook juveniles at the Experimental Fish Hatchery of the Universidade Federal de Santa Catarina, focusing on research about reproduction, larviculture, and ...

Multiple spawning of the fat snook Centropomus parallelus using different dosages of LHRH

2008
The present experiment studied the effect of different LHRHa doses and multiple inductions to obtain consecutive spawnings in one reproductive season of the female fat snook Centropomus parallelus. The LHRHa hormone was administered in cholesterol pellets. Five induction cycles were carried out, with 16 females and 32 males induced per cycle.
