Study reinforces link between gill size and oxygen uptake in fish

A widely debated topic in biology and fisheries sciences is the role of oxygen in the growth of fish and other water-breathing animals. According to new research, developmental changes in individual fish and experimental errors are the causes of inconsistencies that have erroneously been linked to the Gill Oxygen Limitation Theory (GOLT), a theory that was developed to explain the influence of oxygen uptake on fish growth.
