Catch Per Unit Effort of Estuarine Push Net with Emphasis on Occurrence and Abundance of Acetes Shrimps in the Coastal Waters of Malacca, Peninsular Malaysia

Catch per unit effort (CPUE) of estuarine push net (EPN) and abundance of Aeetes shrimps in the coastal waters of Klebang Besar, Malacca were investigated based on the catch data from April 2006 to March 2007. The average monthly CPUE of the EPN observed was 3.53 (± 3.99) kg/fisherman/hour. The total catch comprised of three major categories namely: Aeetes shrimps (90%), fish juveniles (9%) and other shrimps (1%). Amongst the Aeetes shrimps, three species (A. indieus, 87%, A. japonieus, 12% and A. intermedius, 1%) were recorded from the investigated area. The peak catches were observed during the months of September, November and December. There was no significant correlation (p 0.05) between monthly catches and environmental parameters (temperature, dissolved oxygen, salinity and pH).
