Confronting the boundaries: A Bio-physical Economic Assessment of Lake Buhi, Camarines Sur
Type of Session
Full Presentation Panel
Abstract
Lake Buhi, Camarines Sur, Philippines is famous as the home of the world's smallest commercially available fish locally known as "sinarapan" (Mistichthys luzonensis). Unfortunately, intensive aquaculture and agricultural practices in the Lake Buhi watershed has caused the deterioration of the lake's water quality. To assist the community come up with a sustainable management plan for the lake, a two-year assessment was conducted in conjunction with the local Lake Development Office. The results of the study are shared through this proposed panel.

Assessment of the fish abundance and distribution of Lake Buhi
The study focuses on the identification, abundance and distribution of Lake Buhi's fish species. Assessment of the lake's fish species showed that fish abundance and distribution is affected by both water and land use adjacent or near areas where they are collected.

The study focuses on identifying plankton species and determining the lake's productivity. The results showed that the lake is dominated by pollution tolerant species which is an indication of the lake's deteriorating water quality.

The study studies 3 local beliefs of the community as to the reason for fish kills. These are: 1) sulphor upwelling, 2) unsutainable fish farming practices, and 3) nutrient run-off from nearby agricultural lands. The study confirmed that both unsustainable fish farming and agricultural practices contribute to the near annual fish kills.
4) By: Alyana Rodriguez; co-authors: A. Guzman & C.K. Gotangco
The study simulated and modeled various rain events to determine and demonstrate the path of nutrient run-off from different land uses to the lake itself. The study showed that even low intensity rains transport nutrients from the agricultural lands and is discharged to the lake.
