Difference in reproduction energy content in muscles on fish from reservoirs in Paraná State, Brazil

Abstract: The variation in energy in the muscles of the most representative fish species from three Neotropical Reservoirs was investigated to determine the effect of the reproductive process on the amount of energy allocated and a possible relationship between the general welfare of the species and their caloric content. Significant differences were detected between the sexes and among the stages of gonad maturity. In general, the variation in energy in the muscles indicate to be a function of the reproductive cycle.

“…For iteroparous organisms, optimal energy allocation is in response to the trade‐off between current reproductive development and somatic growth, and towards future reproductive development (David & Marschall, 2003). This energy allocation process in fish can be influenced by the tropic category, food quality, habitat conditions and specific reproductive strategy (dos Santos et al ., 2010; Espínola et al ., 2014). Therefore, knowledge of energy metabolism in fish is an indispensable tool for the preparation of suitable artificial diets during the prespawning period (Orlando et al ., 2017).…”
