This study was conducted to assess the status of fisheries and productivity in Lake Pulangui in Bukidnon. Twelve percent (40) of the total fishermen in different age brackets were considered as respondents/key-informants to gather information on the lake′s status. Results revealed that there was a gradual decreased in the total number of fishermen (n=326) in this study as compared to the retrieved data from the years 2011 (n=379) and 2005 (n=390). Gill-nets, cast-nets, and fish-pots were the commonly used fishing gears. However, 6 illegal fishing gears were occasionally reported in the area. On the other hand, the average Catch Per Unit Effort (CPUE) is 6 kilograms indicating that the lake has a fish production of 713,940kilograms in a year which is 35.76% lesser as compared to the year 2011. Among the species recorded, Oreochromis niloticus and Cyprinus carpio were commonly harvested and sold with a price of USD 0.50-1.20/kg. The average kilogram of fish sold per day/person is 3 kilograms with a price of USD 0.70/kg, thus, revealing the total annual revenue of USD 249,879. The results indicate that there was a significant decrease in fish production due to the alteration of the lake′s physical property.
