Anthropogenic Barriers Limit Fish Access to Essential Habitats in the Amazon in the Face of Climate Change. [PDF]

Glob Chang Biol
Rivers across the Amazon Basin are increasingly threatened by climate change and dam construction, which restrict fish movements. We combined climate projections with river‐network connectivity analyses to identify where suitable habitats for frugivorous and socioeconomically important fish are likely to persist and where access may be lost due to ...

Different extenders solutions for tambaqui semen cooling [PDF]

Pesquisa Agropecuária Brasileira, 2016
Abstract: The objective of this work was to evaluate the efficiency of extenders solutions in tambaqui (Colossoma macropomum) semen cooling at 6°C. The treatments consisted of semen dilutions with three extenders - BTS, HBSS, and ACP-104 -, and a control with undiluted semen. Cooled semen was evaluated by 24, 48, 72, 96, and 120 hours.

Phosphorus requirements of tambaqui juveniles

Semina: Ciências Agrárias, 2018
The aim of this study was to determine the requirement of digestible phosphorus in diets for juvenile tambaqui (Colossoma macropomum). 300 juveniles (26.4 ± 0.68 g) were used in a completely randomized design, consisting of six treatments with five replicates and 10 fish per experimental unit. The treatments consisted of six isoprotein, isonitrogenous,

Influência da biomassa inicial sobre o crescimento e a produtividade de peixes em sistema de policultivo Effects of initial biomass on fish growth and fishery productivity in polyculture systems

Ciência e Agrotecnologia, 2006
Analisou-se o crescimento dos peixes, a composição das espécies e a produtividade de quatro policultivos (P75, P78, P87 e P207), visando melhorar o manejo e a produtividade pesqueira dos pequenos açudes (0,1-5,0ha) do Semi-Árido brasileiro. Simulou-se as

Lysine requirement for tambaqui juveniles

Semina: Ciências Agrárias, 2018
The aim of this study was to determine the requirement for lysine in the diet of juvenile tambaqui (Colossoma macropomum). In total, 750 juvenile fish (0.34 ± 0.02g) were distributed in tanks arranged in a randomized block design with six treatments, five replications in two blocks, and 25 fish per unit, for 50 d.

Development of a multi-species SNP array for serrasalmid fish Colossoma macropomum and Piaractus mesopotamicus

Scientific Reports, 2021
Scarce genomic resources have limited the development of breeding programs for serrasalmid fish Colossoma macropomum (tambaqui) and Piaractus mesopotamicus (pacu), the key native freshwater fish species produced in South America.
