The change in the degree of unsaturation of body fats during acclimation of goldfish (Carassius auratus) to high temperature. Hunter, John Gerald

Abstract

An attempt has been made to follow some of the metabolic changes occuring during acclimation of goldfish (Carassius auratus) to temperature. The goldfish were acclimated to certain temperatures and then reacclimated to different temperatures. The change in the unsaturation of their body fats was found using Wij's iodine value determinations. The fats of goldfish fully acclimated to different temperatures show different iodine values. In general the fats are more saturated at higher temperatures. Changes in the amount of unsaturation during the acclimation process have been followed. It has been found upon increase in temperature there is a decrease in the amount of unsaturation.
