Abstract Digital image analysis is a practical, non‐invasive, and relatively low‐cost tool that may assist in the evaluation of body traits Nile tilapia, being particularly useful for assessing difficult‐to‐measure variables, such as areas. In this study, we aimed to estimate variance components genetic parameters areas tilapia obtained by digital images. The data set comprised weight (BW) records 1,917 pond‐reared fish at 366 days age. Of total, 656 animals were photographed subjected trunk...
Although the tambaqui (Colossoma macropomum) is most cultivated native fish species in Brazil, estimated breeding values for growth traits are rarely used selection of superior individuals commercial fingerling production. This study aimed to estimate (co)variance components traits. Body weight, length and width 2500 were determined at tagging 6 12 months after a programme Brazil. Heritability estimates low measured (0.10 0.19) moderate high (0.23 0.81). Common full-sib effects (>73%),...
With the growing concern to obtain quality food, allied aquaculture sector, which has been increasingly important in relation technology, animal welfare focused on fish is a point that needs be linked and integrated. The slaughter several steps precede, all of them influence final product. These are harvest, fasting, transportation stunning, can occur by different methods, affect positively or negatively. Among practices used for slaughter, it includes those cause less suffering better meat,...
Variance components and heritabilities for daily weight gain (DWG) were estimated Nile tilapia farmed in cages across nine generations (G1-G9) of selection a breeding program Brazil. DWG was measured 16,272 accumulated tagged animals representing 535 full- half-sib families under cage farming. The additive genetic variance showed slight variation (0.051-0.066), heritability estimates ranged from 0.20 to 0.33. common environmental effect accounted higher proportion the total DWG, especially...
The homeopathy has been practiced for many years, mainly using rodent as a research model. Zebrafish have used an animal model in different scientific areas and may represent important studies with this therapy. This paper aimed to evaluate the action of Homeopatila 100 ® on growth, liver reproduction zebrafish. study was carried out 192 six months old animals. experimental period three months, being evaluated hepatosomatic viscerosomatic indexes, number hepatocytes per area percentage...
O objetivo com o presente trabalho foi a elaboração de uma revisão que compilasse os principais pontos importantes sobre marcadores microssatélites variabilidade genética Tambaqui (Colossoma macropomum), abordando tópicos relativos ao cenário da aquicultura e à tecnología reprodução peixes nativos. tambaqui é um dos nativos mais consumidos no Brasil e, consequentemente produzidos em cativeiro mesma categoría. Para produção larga escala, conhecer hábitos reprodutivos estratégias manejo se...
Jewel tetra (Hyphessobrycon eques) is a freshwater fish found in several rivers and basins South America. The present study the first to create panel of microsatellite markers for detecting genetic diversity H. eques evaluating application these Serrapinnus notomelas. In total, 44 individuals were genotyped from natural (WIL, n = 20) stock captivity (CAP, 24) population. Moreover, 19 obtained, which only 8 loci presented high degree polymorphism. 45 alleles detected, ranging 126 bp (Hype2G2)...
With the rise of world fish farming, national scenario is favorable for using native intensive farming. Among catfish, Amazonian Jundiá (Leiarius marmoratus) a robust candidate, easy to grow and with good organoleptic characteristics in its flesh. For productive success captivity, it necessary consider some questions about species, such as genetic variability, which must have an acceptable level breeding stock, order maintain diversity; this reduces losses due inbreeding low diversity....
