Estimation of marine fishing capacity of China
Abstrak
By using PTP and DEA methods, the study of marine fishing capacity in China revealed that it's more accurate to consider the input index as total power rather than the number of ships. The analysis clarified that the main issue with marine fishing capacity in China is the excess total power of fishing ships. The study suggested reducing the number of ships by 35.2%, the gross tonnage by 29.8%, and the total power by 37.3% to align with the catch levels of 1999. It also proposed the idea of supplementing peak years. The PTP methodology was found to be suitable for longitudinal analysis over time, while the DEA approach is better for comparing fishing capacity across different regions at the same time. Additionally, the study indicated that practical fishing capacity tends to be underestimated, so actual reductions in capacity are usually larger than calculated values.
