Effect of Sea Surface Temperature and Chlorophyll-A on the Total Catches of Lift Net Fishery in the Padang Pariaman Regency, Indonesia

The  West Sumatera Waters has the potential to be developed for capture fisheries. This potential is utilized through the application of local knowledge for better fishing operations. Fishermen in West Sumatera in determining fishing ground still use the traditional method, namely using previous experience even though on vessels of  > 40 GT and it has been assisted by the fish finder. This study aims to analyze the distribution of sea surface temperature (SST) and chlorophyll-a through Aqua Modis satellite imagery interpretation and analyze its effect on boat lift catch from December 2019 to March 2020. The remote sensing technique via satellite is an efficient method to determine the distribution of sea surface temperature and the distribution of chlorophyll-a. Data from satellites is very helpful in determining temperature and chlorophyll-a. The results obtained are in December 2019 to March 2020 SST distribution ranged from 27 to 30.9°C with dominant SST fluctuating every month and chlorophyll-a concentration ranging from 0.13 to 4 mg m³ with dominant chlorophyll-a concentration fluctuating every month. Sea surface temperature (SST)  and chlorophyll-a simultaneously did not affect the catch.
