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.

Weight-Length Ratio of Piranhas <i>Serrasalmus</i> (Characiformes, Serrasalmidae) in Bolivia: Relationships to Molecular Divergence and Maximum Size? [PDF]

Ecol Evol
This study presents WLRs of nine piranha or palometa fish species of genus Serrasalmus present in the Amazon and La Plata basins of Bolivia and compares differences with genetic divergence (mtDNA COI locus) and the observed maximum size. All species showed an exponential (power type) growth pattern, and all WLRs were significantly different among all ...
