Oocyte quality of tambaqui (Colossoma macropomum) during the reproductive season.
The study aimed to analyze the Colossoma macropomum reproductive behavior and quality of the female gametes throughout the reproductive season. The experiment was carried out in Pimenta Bueno - Rondônia State (Northern Brazil) during the reproductive season (2010-2011) using 36 females. Each sampling was performed on a 15 ± 5 days interval. Female gametes were collected by stripping and the fol...
متن کاملTransportation of juvenile tambaqui (Colossoma macropomum) in a closed system.
The objective of this study was to investigate the effect of density, duration and the use of additives to the water during the transportation of juvenile tambaqui (Colossoma macropomum) and use of this data to establish a safe transportation protocol for the species. The tested products and dosages were: salt (1000, 2000 and 3000 mg/L), gypsum (100, 300 and 500 mg/L) and benzocaine (10, 20 and...
متن کاملGrowth curve by Gompertz nonlinear regression model in female and males in tambaqui (Colossoma macropomum).
Was evaluated the pattern of growth among females and males of tambaqui by Gompertz nonlinear regression model. Five traits of economic importance were measured on 145 animals during the three years, totaling 981 morphometric data analyzed. Different curves were adjusted between males and females for body weight, height and head length and only one curve was adjusted to the width and body lengt...
متن کاملCloning andexpression of cDNA encoding growth hormone tambaqui (Colossoma macropomum) in the yeast Pichia pastoris
Genetic studies involving the search, cloning and expression of genes encoding proteins involved in important physiological processes and advantageous features of the economic standpoint have become the biotechnology research increasingly promising. Due to its zootechnical importance, the encoding gene of growth hormone (GH) of various fish species have been isolated, cloned and expressed in he...
متن کاملResponses of an Amazonian teleost, the tambaqui (Colossoma macropomum), to low pH in extremely soft water.
Our goal was to compare the internal physiological responses to acid challenge in an acidophilic tropical teleost endemic to dilute low-pH waters with those in nonacidophilic temperate species such as salmonids, which have been the subjects of most previous investigations. The Amazonian tambaqui (Colossoma macropomum), which migrates between circumneutral water and dilute acidic "blackwater" of...
