Aquatic Insect Drift At Rocky Substate Of A Small River In Ranchan Recreational Park, Serian

Population composition of aquatic insects in a small river in Ranchan Recreational Park was studied. Samplings were carried out for 6 times to study the pattern of aquatic insects in the river. The samplings were carried out for 24 hours. Surber sampler was used to collect the samples of aquatic i...
