Abstract
This study was undertaken using Principal Component Analysis to describe the trends and variations of fish production in the Philippines. The Philippine fisheries production is mainly accounted for by seven (7) sources by sector, namely: commercial, municipal fisheries, marine municipal, and inland fisheries. By Principal Component analysis, the seven (7) original variables (volume and value per sector) were reduced to only two (2), namely, the volume and value of commercial fisheries. Consequently, the fisheries production of the country is summarily described by the commercial fisheries production. Patterns in fisheries production are similarly dictated only by these two variables. The country's total fish production was extracted from the Philippine Statistics Authority (PSA) from 2015-2017. Results have shown that the production of fish in the country has decreased significantly over the years from 2015 to 2017. This decline was mainly due to the lower commercial production of fisheries. However, the 3-year data on fish production disclosed that commercial fishing had made a significant contribution to the overall production of fish in the country.
