WebDec 7, 2024 · The prevailing determinant of maturation in fishes is thought to be a redirection of energy from growth to reproduction. Instead, the Gill Oxygen Limitation Theory predicts that maturation, and thus reproduction, is induced when a fish reaches a critical ratio of oxygen supply to demand (Q m /Q maint). The consistency of this critical … WebThe prevailing determinant of maturation in fishes is thought to be a redirection of energy from growth to reproduction.

WebMay 4, 2024 · This suggests that somatic growth does not require more than a small part of the large surface area of the gills of highly active fish to supply the oxygen needed for somatic growth (as suggested, e.g., by Koch and Wieser 1983), which would align with crucial aspects of the Gill-Oxygen Limitation Theory of Pauly . WebJul 19, 2024 · The Gill Oxygen Limitation Theory proposes that freshwater and marine fish make the juvenile-to-adult transition when they reach a metabolic ratio of oxygen consumption of 1.36. That is, their body-weight-specific oxygen-uptake capacity is about 1.36 times higher than is required for the maintenance of that body and its functions. gsx750f streetfighter https://kungflumask.com
