抄録: The effect of light condition on size preference for prey clam (Ruditapes philippinarum) and foraging site of Japanese spiny lobster Punulirus japonicus was studied in the laboratory. Light condition was controlled by whether a black curtain was covered over experimental tank or not. Lobsters (60-91mm in carapace length) preferred small clams (>15mm in shell length), and no effect of light condition was detected on the prey size preference. However, lobsters seemed to forage around feeding spot under dark condition while they did around shelter under light condition, suggesting that predation pressure for lobsters might vary with light level in the field.
