Abstract

In an earlier paper read before the Academy, data were given on the comparative ratio of oxygen consumption in certain fishes and other marine forms. These figures were obtained by analysis of samples of water in which the animals had been kept, using the chemical method devised by Winkler. As is customary in such work, the figures of consumption were reduced to the volumetric basis at uniform pressure and temperature and were expressed in cubic centimeters per gram of body weight per hour. There resulted from these studies an interesting comparison in metabolic rate in the different fishes, being greatest in active fishes like the mackerel (ave. 0.726 cc. per gram per hr.) and the butterfish (ave. 0.301 cc. per gram per hr.) and grading down in the more sluggish forms like the flounder, tantog and sea-bass to a figure (ave. 0.070 cc. per gram per hr.).
