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

open access: yesJ 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]

open access: yesScientificWorldJournal, 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 ...

A meta‐analytic review of monoterpene for fish anaesthesia

open access: yesFish 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

open access: yesEnvironmental 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

open access: yesJournal 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 ...

Genomic selection signatures in farmed Colossoma macropomum from tropical and subtropical regions in South America

open access: yesEvolutionary Applications, Volume 15, Issue 4, Page 679-693, April 2022., 2022
Abstract Tambaqui or cachama (Colossoma macropomum) is one of the most important neotropical freshwater fish used for aquaculture in South America, and its production is concentrated at low latitudes (close to the Equator, 0°), where the water temperature is warm.

Novel universal primers for metabarcoding environmental DNA surveys of marine mammals and other marine vertebrates

open access: yesEnvironmental DNA, Volume 2, Issue 4, Page 460-476, October 2020., 2020
Several barcode loci targeting teleost fish and elasmobranchs have previously been developed, but to date primer sets focusing on other marine megafauna, such as marine mammals, have received less attention. Similarly, there have been few attempts to identify potentially “universal” barcode loci which may be informative across multiple marine ...

Organoleptic and nutritional characteristics of fillets of pirapitinga fed different protein sources in a biofloc system [PDF]

open access: yesPesquisa Agropecuária Brasileira, 2020
Abstract: The objective of this work was to assess the organoleptic and nutritional quality of fillets of cultured pirapitinga (Piaractus brachypomus), fed diets with either partial or total substitution of fishmeal, and to determine the nutritional quality of the biofloc meal.
