The present research was designed to study the effect of light exposure and shelter on Mystus cavasius. Fingerlings were stocked in each tank for the evaluation of growth and survival, continued for six weeks. The fingerlings were reared in three treatments with three replications, first was normal open tank, second was provided with shelter for hiding and third was completely covered with polythene sheet to provide dark environment for six weeks. Specific growth rate, feed conversion ratio, protein efficiency ratio and survival rate were observed at every fifteen days interval. At the end of the experiment result showed that maximum weight was observed in tanks which were provided with hiding space however the length of fish after six weeks of experiment were not varying much.
