Intestinal responses in pacu (Piaractus mesopotamicus) exposed to fasting and refeeding nutritional management. [PDF]

Anat Rec (Hoboken)
Abstract Fasting is a practice in the aquaculture industry that aims to reduce feed costs. This practice can affect the gastrointestinal system of fish. The intestine plays a pivotal role in the nutrition and overall health of fishes. The present study sought to evaluate the effects of fasting and refeeding on body weight, intestine somatic index (ISI),

Standardization of Immunohistochemistry Using an Anti-WASLB Antibody in the Skeletal Muscle of Teleost Fish. [PDF]

Curr Protoc
Abstract Immunohistochemistry (IHC) is a widely used technique for the identification, localization, and analysis of protein expression in tissues, playing a critical role in pathological diagnosis and validation of data derived from molecular biology. Despite its well‐established use in mammalian tissues, applying IHC to fish still presents challenges,

Molecular characterization of Serrasalmidae hybrid in the upper Paraná River floodplain using molecular markers. [PDF]

J Fish Biol
Abstract This study reports the molecular identification of a tambacu—a hybrid of Colossoma macropomum and Piaractus mesopotamicus—in the floodplain of the upper Paraná River using molecular markers. The PCR‐GEL method, based on the analysis of COI and TROP fragments, successfully characterized the hybrid, while PCR‐SEQ, employing RAG2 and TROP markers,

Contribution of Amino Acids in Cereal Grain Products to Precision Feed Formulation for Tambaqui (Colossoma macropomum) Using a Digestibility Approach. [PDF]

J Anim Physiol Anim Nutr (Berl)
ABSTRACT Although cereal grain products have low protein content, they can contribute up to 25% of total protein in low‐trophic level/omnivorous fish diets. Thus, understanding the amino acid contribution of these ingredients becomes crucial for meeting the dietary requirements of omnivorous fish.
