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 ...

Effects of dietary aflatoxin B1 on accumulation and performance in matrinxã fish (Brycon cephalus). [PDF]

PLoS One, 2018
Aflatoxins (AF) can be cumulative in fish tissues and can influence weight, length, feed intake and survival depending on the species. The aim of this work is to measure performance and aflatoxin levels in tissues of matrinxã (Brycon cephalus) fish chronically exposed to aflatoxin.

Effects of Dietary Aflatoxin B1 on Hybrid Grouper (Epinephelus fuscoguttatus ♀ × Epinephelus lanceolatus ♂) Growth, Intestinal Health, and Muscle Quality. [PDF]

Aquac Nutr
This study investigated the effects of varying doses of dietary aflatoxin B1 (AFB1) on the growth, intestinal health, and muscle quality of hybrid grouper. Four diets with varying AFB1 concentrations (0, 30, 445, and 2,230 μg kg−1) were used. Elevating AFB1 concentrations led to a decline in growth indexes, specifically the weight gain rate and the ...
