ABSTRACT
Cephalopods is one of the major fish groups in the Malaysian fisheries which accounts for 5 - 6 % of the total fish landings. Compared to the finfishes, information on their biology, distributions and migration activities are very scarce. The data from the fisheries resource survey carried out by K.K. MANCHONG from September 1997 to November 1998 had been used to study the biology of the cephalopods in Malaysian waters. The study included species composition and distribution, maturity by areas and growth parameters of the dominant squid species, Loligo duvaucelli, Loligo chinensis and Loligo singhalensis. About 17 species from 6 families have been identified in the west coast of Peninsular Malaysia and in the South China Sea; including Sarawak and Sabah waters. Family Loliginidae dominated the catch of the cephalopods which consist of 6 species; Loligo duvaucelli, Loligo chinensis, Loligo singhalensis, Loligo tagoi, Loligo sibogae and Sepioteuthis lessoniana. Oceanic squids from Family Ommastrephidae (Todarodes pacificus and Nototodarus philippinensis) were also found toward the continental slopes off Sarawak and Sabah waters. The squids were more abundant in the west coast areas compared to the east coast with L. duvaucelli dominating the catch while in the east coast (including Sarawak and Sabah waters) L. chinensis was the dominant species. Cuttlefishes (Family Sepiidae) were more diverse in species composition in Sarawak waters, where 6 species have been identified. Distributions of matured and immature squids from 3 common squid species; L. duvuacelli, L. chinensis and L. singhalensis, in the west coast and in the South China Sea were mapped up and length frequency distributions which represent the number of cohorts were also studied.
