The Sape Strait Cephalopod Resource and Its Response to Climate Variability
Abstract: Of seven cephalopod
species occurring in the Sape Strait, four species of squid constitute 90% of
the annual cephalopod catches. The squid fishery is described, with emphasis on
its fluctuating catches due to the combined effects of fishing and climate
variability. Two most important fishing gears, ‘Bagan Prahu’ (boat raft net)
and ‘Jala Oras’ (light lured payang) were used and standardized in catch and fishing effort analysis. The southern
oscillation index (SOI) was used to represent the climate variability
component. A model was then developed by means of incorporating the SOI,
fishing effort and squid catch. Average annual values of these three components
were used to construct the model. The model can be a useful tool for predicting
the squid catches. Its use for forecasting and managing the fishery requires
regular monitoring the catch, fishing effort and the SOI, preferably monthly.
Research and management implication of this finding is discussed.
