Abstract: ABSTRACT Tambaqui, Colossoma macropomum, is one of the most produced species in Brazilian fish farming, which has boosted the development of new technologies to increase its productivity. The aim of this study was to evaluate production performance in two second-generation tambaqui stocks selectively bred for weight gain in a semi-intensive rearing system and assess its influence on total production cost. We analyzed 300 fish (initial mean weight and standard length of 160 g and 17 cm, respectively) of… Show more

“…The increase in fish production and consumption is directly linked to the need to enable technologies for the reuse of residues generated by the aquaculture industry (Hussein & Mansour, 2018). The organic material originating from fish processing is an economically viable source of high quality proteins, oils, vitamins and minerals (Silva et al, 2020), in addition to containing nutrients that contribute to ecological biodiversity, such as: nitrogen, phosphorus, carbon and potassium (Ghaly et al, 2015). Some processing units in Rondônia state silage residues as an alternative for proper disposal (Cavali et al, 2020).…”

“…This study also estimated parameters for a new trait of interest for industrial fish processing, loin eye area (LEA), with h 2 = 0.39. These outcomes show significant potential for selective breeding programmes to yield large genetic gains and improved performance 219,220. Attempts to develop genetically superior strains for farming purposes have been implemented221 ; however, the advances in understanding of quantitative genetics have not markedly affected commercial tambaqui production, which still relies on non-selectively bred, captively propagated broodstock.…”
