The study was conducted in four sampling stations. Four enumerators were hired mainly to collect data from 142 fishermen-respondents daily. Researchers also conducted actual monthly fishing in the four stations. There were 13 commercially important mollusks inhabiting the four stations. These were Loligo spp. (pusit), Octopus spp. (Kurita), Asprella (Kalauit), Ostre spp. (tirem), Gari costulata (onnok), Nocula nucleva (bennek), Tagelus plebelus (Kawa-kawayon), Scapharca inequivulvis (sombaboy), clams (sungotan), Pharus legumen (Kasim), Berthalinia chloris (ping-pinggan), Ammenssium japonicum (Kampis), and and Auger turritela (dawdaw). Among the four stations, station 3 had the most number of species of mollusk collected. Peak season for mollusks occur from Feb-April and lean month is Nov. In terms of volume of catch, oysters ranked first during the conduct of the study with an average volume of harvest of 66.74 kg or 87.07% of the total mollusks catch. On the other hand, Pharus legumen, got the least catch with an average catch of 50 kg or only 0.07% of the total mollusks catch
