Summary

Equations have been derived interrelating length, weight and oxygen consumption inChanos chanos. The uses which these equations can be put to in the study of the transport of live fish have been discussed in detail.

The need has been pointed out for taking into account the size (especially the weight) effect in interpreting the data on the respiration of fish. While a mere grouping of fish in terms of their length-ranges or number in a given volume of water is not directly helpful in interpreting the experimental results, the factor, ml. (initial) oxygen per gm. fish, can be used with advantage to measure the influence of size on the respiration of the fish and to compare the viability of the fish under different environmental conditions. On the basis of this factor, mortality ofChanos fry in hard tap water is seen to be relatively less than in sea-water; while, under conditions of asphyxiation, the median survival time of the fry does not appear to be affected to any significant extent by the salinity of the medium.
