Changes in environmental quality in the lake found the highest riparia Pinang Luar Lake indicated by a decrease in the plant canopy, increasing water temperature, a decrease in oxygen content and pH of the water, as well as the lowest of fish species diversity, the spread of the fish tends to uneven compared to two other lakes.
