Cytogenotoxicity biomarkers in fat snook Centropomus parallelus from Cananéia and São Vicente estuaries, SP, Brazil
The aquatic environment receives many contaminants that can induce damages at the molecular, biochemical, cellular and physiological levels. Centropomus parallelus, an important food resource for local populations, is a predator fish that feeds on small fishes and benthic invertebrates, thus being vulnerable to the bioconcentration and biomagnification processes. This study aimed to evaluate cy...
متن کاملEarly development of fat snook, Centropomus parallelus (Poey 1860) (Teleostei, Centropomidae) from Southeastern Brazil.
Early development of fat snook, Centropomus parallelus (Poey 1860), is described based on embryos. and larvae obtained from rearing experiments and from specimens caught in the field, in Cananéia, southeastern Brazil, during December 1999-January 2000. Larvae of common snook, C. undecimalis, were also collected to compare the pigmentation pattern and body shape. Eggs of C. parallelus were relat...
متن کاملThe effect of salinity on osmoregulation and development of the juvenile fat snook, Centropomus parallelus (POEY).
Eurihaline fish support waters with different salt concentration. However, numerous studies have shown that salinity can affect fish development. Thus, the effect of salinity change from 20 to 5 and 35 on survival, weight, length, gill chloride cell ultrastructure and gill Na+, K+ ATPase activity was evaluated in Centropomus parallelus following short-term (6, 24 and 96 hours) and long-term exp...
متن کاملEffect of dietary (n-3) highly unsaturated fatty acids on growth and survival of fat snook (Centropomus parallelus, Pisces: Centropomidae) larvae during first feeding.
The effect of rotifers, Brachionus rotundiformis (S-type), fed three different diets: A (rotifer fed Nannochloropsis oculata), B (rotifer fed N. oculata and baker's yeast, 1:1), and C (rotifer fed N. oculata and baker's yeast, 1:1, and enriched with Selcoregister mark or target), was evaluated based on the survival, growth and swim bladder inflation rate of fat snook larvae. Rotifers of treatme...
متن کاملTiming of embryonic quiescence determines viability of embryos from the calanoid copepod, Acartia tonsa (Dana)
Like 41 other calanoid copepods, Acartia tonsa, are capable of inducing embryonic quiescence when experiencing unfavorable environmental conditions. The ecdysone-signaling cascade is known to have a key function in developmental processes like embryogenesis and molting of arthropods, including copepods. We examined the role of ecdysteroid-phosphate phosphatase (EPPase), ecdysone receptor (EcR),...
