Diversity of fish fauna and water quality om upper Batang Baram, Miri Sarawak

A study was carried out to document the diversity of fish fauna and selected water quality parameters at Lio Mato and Long San, Batang Baram, Miri. A total of 6 stations were selected at each of the areas. Fish sampling gears such as monofilament gill nets of different mesh sizes, three-layered ne...

A total of 6 stations were selected at each of the areas. Fish sampling gears such as monofilament gill nets of different mesh sizes, three-layered nets, cast net, electroshocker device and scoop nets were used. A total of 1068 individuals were caught with Cyprinidae as the dominant family (62.84 %), followed by Siluridae (23.22 %) and Balitoridae (5.81 %). The dominant species are Kryplopleros macrocephalus (N= 163), followed by Lobocheilos falcifer (N= 149) and Crossocheilus nigriloba (N= 136). Lio Mato recorded a Shannon-Weiner diversity index of 2.3239, Margalefs richness index of 4.6211 and Pielou's evenness index of 0.6901, whereas Long San recorded diversity index of2.6552, richness index of 5.881 and evenness index of 0.7248.

Temperature ranged from 24.1 to 31.5 °C, pH ranged from 6.81 to 7.57, dissolved oxygen ranged from 6.66 to 8.13 mg/L, turbidity ranged from 0.13 to 504.70 NTU and conductivity with a range of 24 to 97 J.1S/cm.
