Diamondback squid (Tysanoteuthis rhombus) exploration in the South China Sea, Area III: Western Philippines

Abstract

The diamondback squid (Tysanoteuthis rhombus) is a potential resource popularized mainly for the export market in the Central Philippines and the positive results from other experimental activities. Exploratory fishing for the species using the giant squid jig was conducted on board MV SEAFDEC and MV Maya-Maya in the South China Sea (Western Philippines) to determine its occurrence, abundance and distribution in these areas. The gear employed is basically used in small boats hence, its operation on bigger vessels was very difficult. The result was discouraging with only one diamondback squid caught out of the 175 jigs set. The description and fishing operations of the gear are presented with comparison from other research and fishing results conducted in Camotes Sea, Calauag Bay, and Ormoc Bay which are considered potential areas.
