Abstract

The effect of exposure to different concentrations of sea water on the initial
mortality of Spratelloides delicatulus, the common tuna-live-bait fish of Lakshadweep,
was experimented. The shock mortality of the fish due to stress of capture
was found to be greatly! reduced by introducing them at once in 50% sea water.
However, the aggregate mortality from the time of capture to the end of the
second day was least among the fish exposed to 75% sea water, being about
three-fourth of the mortality in 100% sea water.
