The Vital Role of Oxygen in Fish Growth

A hot topic in the realms of biology and fisheries sciences revolves around the critical role of oxygen in the growth of fish and other aquatic creatures. New research is shedding light on how inconsistent findings related to the Gill Oxygen Limitation Theory (GOLT)—which posits that oxygen uptake limits fish growth—stem from developmental changes in individual fish and experimental inaccuracies.

Groundbreaking Research from the Sea Around Us Initiative

In a compelling paper published in the journal *Fishes*, experts from the Sea Around Us initiative at the University of British Columbia and Leiden University analyzed data from 33 diverse fish species. Their findings reinforce the argument that minor fluctuations in oxygen consumption and gill surface area do not undermine the foundational principles of GOLT.
