Bio-Physico-Chemical and socioeconomic assessment of Sarnap Lake in relation to its fishery productivity

Abstract

The main concern of the study was to assess the bio-physico-chemical and socioeconomic factors affecting the productivity of Sarnap Lake as bases for the formulation of policies on optimum lake utilization. Baseline data on selected bio-physico-chemical characteristics of the lake gathered and analyzed from November 1987 to April 1988. Trends observed were compared with those of other lakes in the country, particularly those found in Luzon. Apparent similarities were noted. Socioeconomic data on the fishing households in the study area along the levels of fish production for open fishing in the lake, were also established. Aggregate fish production during the study period was 6,287.6 kilos, with gill net giving the biggest share (31.3percent) of the catch. It was followed by fish shelter (28percent), pole and lines (23.2percent), and fish traps (17.5percent). The productivity of selected fishing gears was determined, as well as the bio-physico-chemical changes and the socioeconomic factors, which affect productivity. Simple cost and returns analyses of the different fishing gears revealed that they were economically profitable, except "as-asad.". Recommendations on how to develop and manage the lake's resources were formulated based on the findings.
