Gill-oxygen limitation theory

WebFeb 27, 2024 · The Gill Oxygen Limitation Theory (GOLT) posits that a mismatch in oxygen supply and demand stemming from geometric constraints on gill surface area limits metabolic rate and energy available for biological processes. This theory has been suggested to explain numerous phenomena observed with warming yet is based upon a … WebSep 22, 2024 · In contrast, the Gill‐Oxygen Limitation Theory (GOLT) postulates that (a) fish growth slows because as they grow, their two‐dimensional ability to extract oxygen from the water diminishes relative to their three‐dimensional weight gain, and (b) they can only invest energy for maturation if oxygen supply at their size at first maturity (Q ...
