| Abstract | ||||
| This study aimed to identify the species composition, assess the relative abundance, determine the catch per unit effort and the diversity index of the species caught by the bottom set gillnet in Caba, La Union, Philippines. Descriptive method of research was used in the study. Data were gathered through field research and collection of samples and analyzed using percentages and presented in tables and graphs. Results revealed that 43 species belonging to 10 orders and 23 families were identified from the total of 1,324 individuals collected. Gazza minuta is the most abundant species in the area with 30.89% of the total sample population. The highest catch per unit effort was recorded in October 2024 with 0.0100 (kg/hr/unit of gear) and lowest in March 2025 with 0.0055 (kg/hr/unit of gear), with an average of 0.0076 (kg/hr/unit of gear) which means low value. Diversity index was 2.63 indicating that species in the area are moderately diverse. These results emphasizes the efficiency and gear selectivity of bottom set gillnet in relation to species abundance and diversity in the area, which also influence the catch of the fisherfolk. | ||||
