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,

Morphometric Evaluations and Yields from Commercial Cuts of Black Pacu Colossoma macropomum (Cuvier, 1818) in Different Body Weights. [PDF]

ScientificWorldJournal, 2021
For the Amazon, it is important to encourage the production of native fish, since there are several species of zootechnical interest. For this, it is necessary to know the species since its acquisition, production, processing, and marketing. Therefore, the aim of this study was to analyze the yield, correlations, and profitability of different cuts of ...

Production of cachama reciprocal hybrids in earth ponds [PDF]

Ciência Rural, 2019
: The growth of cachama hybrids, cachamoto (Colossoma macropomum ♀ x Piaractus brachypomus ♂) and cachamay (P. brachypomus ♀ x C. macropomum ♂) was compared for 154 days to determine which showed the better productivity.

A meta‐analytic review of monoterpene for fish anaesthesia

Fish and Fisheries, Volume 24, Issue 3, Page 367-380, May 2023., 2023
Abstract The use of anaesthetic agents has been increasing to address the welfare needs of different fish species in scientific and aquaculture practices. MS‐222 is the most used synthetic anaesthetic but some limitations and side effects have been reported.

Short‐term temporal variation of coastal marine eDNA

Environmental DNA, Volume 4, Issue 4, Page 747-762, July 2022., 2022
Short‐term temporal variation in eDNA has been largely unexplored. We here show that fish and eukaryote communities at a coastal site change throughout the day, reflecting known biology of the species in question. These findings are important to consider regarding experimental design for future studies Abstract Temporal variation in eDNA signals is ...

Growth, red blood cells, and gill alterations of red pacu (Piaractus brachypomus) fingerlings by chronic exposure to different total suspended solids in biofloc

Journal of the World Aquaculture Society, Volume 53, Issue 3, Page 652-668, June 2022., 2022
Abstract Chronic exposure to high biofloc total suspended solids (TSS) could affect growth, red blood cells, and generate gill alterations in fish. Red pacu, Piaractus brachypomus, fry (2.7 ± 0.5 g weight) were exposed to different biofloc TSS concentrations with low (T1: 200–300), and medium (T2: 400–600 mg/L) levels and compared to a treatment ...
