Abstract

The present study aimed to determine the composition of aquatic insects and fish of small stream at Kubah National Park, Sarawak. The drift pattern exhibit by aquatic insects and its association with water parameter also was studied. Aquatic insects samples of the small stream were collected every three hours over twenty-four hour period using Surber sampler for five sampling study. Samples were collected every three hours along with the measurements of water temperature, pH, dissolved oxygen, turbidity, total suspended solids, water velocity and depth of water at the Surber sampler mouth. Members of the Order Diptera dominated the drift, accounting to 28% of the total drift, followed by members of the Orders Plecoptera and Trichoptera were the second and third most abundant groups, respectively. There were 91.75 individuals per 100 m³ of volume water filtered. Total number of insect was significantly, positively correlated with dissolve oxygen and total volume of water filtered by the sampler. The drift of aquatic insects were most active during the mid-morning to mid-afternoon, 0900-1200 hour. Statistical test showed no significant differences between day and night drift densities although drift density is 0.5% higher during the daytime compared to nighttime. A total of 47 individuals of fish were caught comprising of Family Clariidae, Cyprinidae and Belontidae accounting to 45%, 42% and 13% respectively.
