Result of one-way analysis of similarity (ANOSIM) between the biomass of ecological catch parameters and vessel size group is statistically significant level : p<0.05; p<0.001.
The highest contribution (gray shade) is defined as a characteristic species (fish group) in each cantrang size group.
GT, gross tons; TL, trophic levels.
