Abstract Scarce genomic resources have limited the development of breeding programs for serrasalmid fish Colossoma macropomum (tambaqui) and Piaractus mesopotamicus (pacu), key native freshwater species produced in South America. The main objectives this study were to design a dense SNP array group validate its performance on farmed populations from several locations Using multiple approaches based different tambaqui pacu, final list 29,575 29,612 putative SNPs was selected, respectively,...
Abstract Background Megaleporinus macrocephalus (piauçu) is a Neotropical fish within Characoidei that presents well-established heteromorphic ZZ/ZW sex-determination system and thus, constitutes good model for studying W Z chromosomes in fishes. We used PacBio reads Hi-C to assemble chromosome-level reference genome M. . generated family segregation information construct genetic map, pool-seq of males females characterize its sex system, RNA-seq highlight candidate genes determination....
Computer vision system (CVSs) are effective tools that enable large-scale phenotyping with a low-cost and non-invasive method, which avoids animal stress. Economically important traits, such as rib loin yield, difficult to measure; therefore, the use of CVS is crucial accurately predict several measures allow their inclusion in breeding goals by indirect predictors. Therefore, this study aimed (1) validate deep learning approach automatically morphometric measurements tambaqui (2) estimate...

Tambaqui (Colossoma macropomum) is the main native fish produced in continental aquaculture from South America. However, its production has been negatively affected by significant economic losses due to frequent outbreaks caused parasite Ichthyophthirius multifiliis. Genetic selection for I. multifiliis resistance may represent a sustainable and effective alternative reduce mortality and, therefore, improve of tambaqui. The estimation genetic parameters needed validate whether can be...
Tambaqui or cachama (Colossoma macropomum) is one of the most important neotropical freshwater fish used for aquaculture in South America, and its production concentrated at low latitudes (close to Equator, 0°), where water temperature warm. Therefore, understanding how selection shapes genetic variations structure farmed populations paramount importance evolutionary biology. High-throughput sequencing generate genome-wide data species allows elucidating genomic basis adaptation local...
Nile tilapia is the main farmed fish in Brazilian aquaculture. Streptococcus agalactiae (GBS) responsible for high mortality rates farms. Genetic improvement considered an effective alternative producing resistant animals The objective of this study was to estimate genetic parameters resistance GBS infection a breeding population from Brazil, based on disease challenge using circulating serotype (Ib and ST-NT). Furthermore, correlations between average daily gain (ADG) were estimated...
In South America, Tambaqui (Colossoma macropomum) stands as the primary target for aquaculture, yet breeding programs this Amazon native species are in their early stages. While high-density single nucleotide polymorphism (SNP) arrays pivotal aquaculture breeding, costs can be prohibitive non- or semi-industrial species. To overcome this, a cost-effective approach involves developing low-density SNP followed by genotype imputation to higher densities. study, 1K array tambaqui was created and...
Abstract Background Growth and carcasses yield are economically important traits for the Amazon fish tambaqui ( Colossoma macropomum ). However, has received little attention in breeding programs because it is difficult to measure on many cannot be directly measured candidates. The goal of this study was unravel genetic architecture growth traits, as well identify candidate genes influencing these an experimental population Southeastern Brazil, by using ddRAD-sequencing (double digest...
