Diversidade genética de estoques de reprodutores de Colossoma macropomum
(2009) [Artigo de periódico]Analisou-se a diversidade genética de estoques de reprodutores de Tambaqui (Colossoma macropomum), mediante o uso de marcador RAPD, utilizando-se 10 primers para analisar 30 amostras do estoques de reprodutores das ... -
Functional integrity of Colossoma macropomum (Cuvier, 1816) sperm cryopreserved with enriched extender solutions
(2015) [Artigo de periódico]Cryoprotectant solutions are used to protect the sperm from alterations caused by the low temperature in the cryopreservation process. We evaluated the quality of Colossoma macropomum semen after freezing, using dimethyl ... -
Genetic diversity of tambaqui broodstocks in stock enhancement programs
(2017) [Artigo de periódico]Natural populations of tambaqui (Colossoma macropomum) have significantly decreased in recent decades especially due to human extraction activities. So that the environmental impact may be reduced, the restocking of fish ... -
Growth curve by Gompertz nonlinear regression model in female and males in tambaqui (Colossoma macropomum)
(2015) [Artigo de periódico]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 ... -
Morphological and morphometric analysis of skeletal muscle between male and female young adult Colossoma macropomum (Characiformes: Serrasalmidae)
(2016) [Artigo de periódico]This study aimed to evaluate muscle organization in tambaqui in order to describe the muscle growth process. We analyzed the morphometric pattern of fibers from white muscle of young-adults (300 days) by smaller diameter. ... -
Oocyte quality of tambaqui (Colossoma macropomum) during the reproductive season
(2015) [Artigo de periódico]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 ... -
The germ cell marker dead end reveals alternatively spliced transcripts with dissimilar expression
(2019) [Artigo de periódico]Since the late 19th century, the Amazon species Colossoma macropomum (tambaqui) has been exploited commercially and the climate change has contributed to decline in tambaqui numbers. Although germ cell cryopreservation and ... -
Variabilidade genética em tambaquis (Teleostei: Characidae) de diferentes regiões do Brasil
(2010) [Artigo de periódico]O objetivo deste trabalho foi avaliar a diversidade genética em quatro estoques de tambaquis (Colossoma macropomum) de diferentes regiões do Brasil, por meio de marcador RAPD. Foram utilizados 10 iniciadores para analisar ...
