  A study was conducted for a 12-month period, from June 2008 to May 2009 based on the catch data to determine the catch composition of Set Bag Net (SBN) that is a type of fishing net laid down to catch Acetes shrimps that move along the estuary of Merbok River in the state of Kedah, Peninsular Malaysia. Bag net is a static traditional gear with a cod end mesh size measuring 0.5 cm. The results showed that total catches of the bag net over a year period were constituted of three major catch groups viz. Acetes shrimps (89%), juvenile fishes (9%) and other non-Acetes shrimps (2%). The annual mean percentage composition of sergestid shrimps comprised of A. japonicus, A. vulgaris and A. indicus were found to be 89, 7 and 4%, respectively. The gear is very selective and besides Acetes there was also a small proportion of fish juvenile being caught. Seven species of juvenile fishes were recorded throughout the catch period however; their mean total abundance was very low (9%). Penaeid shrimp was the only group of non-Acetes shrimp been recorded. Based on the analyzed catch composition data, it could be concluded that SBN is Acetes-selective and not causing significant great damage to the juvenile fish population inhabiting the study area.

  The study on food and feeding habits of planktonic shrimp Acetes japonicus were done by examining the stomach contents of 164 specimens between June 2008 and May 2009. Samples were obtained from the bag net that was set along the bank of Tanjung Dawai estuary. Diet compositions of A. japonicus were grouped into eight major categories: phytoplankton, zooplankton, algae, appendages of crustacean, plant matter, debris, unidentifiable items and sand and mud. Analysis on the percentage of numerical abundance (Ci) showed that plant matter (28.18%) and crustacean appendages (18.70%) as the two highest values amongst the eight categories of food items. In addition, percentage frequency of occurrence (Fpi) values of phytoplankton, zooplankton, algae, plant matter, appendages of crustacean, debris, unidentified items and sand and mud were 3.54, 7.05, 5.07, 27.44, 17.42, 15.80, 8.94 and 19.81%, respectively. On the basis of food composition found in the stomach, it can be concluded that A. japonicus is omnivorous in feeding habit.
