Abstract
Groups of laboratory-reared, juvenile lobsters (Homarus gammarus, 40–50 g wet weight) were given different types of food (shrimp, mixed invertebrates and pellets, bivalves, starved) for a period of 22 wk. Haemocyanin concentration was measured weekly, moult stage and moultings noted. Haemocyanin concentration decreased rapidly in the starved group (from 0.8–0.6 to 0.2 mM). The group fed with bivalves showed a small decline with time, to 0.5–0.3 mM at the end of the period, indicating a deficient diet. The haemocyanin in the other groups did not change significantly during the experiment. Moultings decreased in frequency and the intermoult period was prolonged when the quality of food was decreased, and in the starved group moulting ceased completely after 1.5 months. Haemocyanin concentration was lowest immediately after moult and increased gradually through stages C and D. Lobsters that were starved or maintained on the bivalve diet did not reach the same premoult haemocyanin levels as those fed with shrimps and mixed food.
