We evaluated vulnerability of pelagic larvae and early settled juveniles in Manila clam Ruditapes philippinarum to various invertebrate predators. Predation trials in laboratory revealed that moon jellyfish Aurelia sp. and oyster Crassostrea gigas prey upon the pelagic larvae of clam. We also found that grass shrimp Palaemon serrifer, Xanthidae crab Leptodius exaratus, subtropical pebble crab Gaetice depressus, sea cucumber Apostichopus japonicus and hermit crab Pagurus minutus feed on clam juveniles, and that P. serrifer and P. minutus consume > 90 clam juveniles within 24 h. Manila clam in the early life stage are thus highly vulnerable to various predators.
