Replacement of Fish Meal With Poultry Viscera Meal in Diets for Juvenile Arapaima gigas: Growth Performance, Hematological Parameters, Fillet Composition, and Gut and Liver Histology

Aquaculture Research, Volume 2026, Issue 1, 2026.
This study aimed to evaluate the effects of replacing fish meal with poultry viscera meal (PVM) in diets for juvenile Arapaima gigas, assessing growth performance, hematological parameters, fillet composition, and gut and liver histology. Five isonitrogenous (450.20 g kg−1 crude protein [PRO]) and isocaloric (20.02 MJ kg−1 gross energy) diets were ...

Níveis de proteína bruta para juvenis de pirarucu Crude protein levels for juvenile pirarucu

Pesquisa Agropecuária Brasileira, 2005
O objetivo deste trabalho foi avaliar o efeito de quatro níveis de proteína sobre o crescimento de juvenis de pirarucu, Arapaima gigas. O experimento foi conduzido em delineamento inteiramente casualizado, com de quatro tratamentos (32,7%, 39,3%, 43,4% e 48,6% de proteína bruta), três repetições cada. Foram utilizados 120 peixes, com peso médio inicial

Amazonian fish migration as a social–cultural–ecological process

People and Nature, Volume 7, Issue 12, Page 3297-3312, December 2025.
Abstract In this study, we highlight the rich perspectives and explanations of fish migration held by Indigenous groups across the Amazon. We present the aspects of Indigenous cosmological stories, drawing from our exploratory review of cultural ethnographies and grey literature, as well as the authors' own experiences. We ask, how do Amazonian peoples
