Abstract

The effect of size and maturity on food conversion efficiency of the spiny lobster, Pur~rrlirrrsh onrcrrirs was studied using clam meat as feed. Rates of feeding. assiniilation, metabolism and conversion showed negative correlation with increase in size. Maximurii feeding rate of 254.87 j/ g/day was recorded in the smallest size group (l3.17g). Net energy conversion efficiency, excluding exuvia, was highest - 15.4% - in the smallest size group and decreased to 6.6% in the biggest size group (256.668). Considerable quantity of converted energy was lost as exuvia and the loss showed a positive correlation with increase in size. Total energy budget has been estimated for different size groups. Onset of maturity induces definitechanges in feeding, conversion and metabolic rates in P. homarus.
