A series of experiments was conducted with American lobsters ( Homarus americanus ) and European lobsters ( Homarus gammarus ) to develop methods to reduce cannibalism among communally‐reared juveniles. The primary factors studied were substrate type, stocking density and photoperiod. Other conditions investigated were the effects of different water Temperatures, food type, segregating large individuals and claw immobilization. Preliminary studies also were conducted on the effects of shelter density, feeding level and tank area. These studies showed that by the use of vertical substrates, segregating techniques and immobilization of claws, carrying capacity can be increased considerably.
