Scientists Confirm 53 Fish Species in Water System in Kulen Promtep Wildlife Sanctuary

A total of 1,895 ?sh have been captured, representing 53 species in 17 families from the assemblage structure in seasonal wetlands in the dry dipterocarp forests of Kulen Promtep Wildlife Sanctuary, according to the Cambodian Journal of Natural History.

Dipterocarp forests are common in the northern plains of Cambodia, but little is known about the ?sh that occupy seasonal wetlands in there, it added.

With pressures increasing on Cambodian wetland resources, more information is needed on the value of small wetlands. We describe ?sh assemblages in seasonal wetlands in Kulen Promtep Wildlife Sanctuary based on sampling completed during the early-wet, wet and dry seasons in 2015�2016. A total of 1,895 ?sh were captured, representing 53 species in 17 families, it pointed out.

Fish assemblages were most diverse during the wet season according to the Shannon-Weiner index and species richness. We were not able to identify distinct seasonal assemblages using non metric multi-dimensional scaling, which may have been due to di?erences in sampling e?ort between seasons.

There was no signi?cant correlation between log-transformed wetland area and diversity measures, although correlations between maximum water depth and diversity were signi?cant and positive.

Based on these results indicated that water depth may be important in in?uencing the diversity of ?sh assemblages and presence of common species in seasonal wetlands.

Kulen Promtep Wildlife Sanctuary is the largest protected area in Cambodia. It was set aside to protect the critically endangered, possibly extinct Kouprey. It is located in the northern plains of Cambodia.
