The proportions (weight) of the species composition and average size of species caught were compared by tide type tide. T-Test was used to check whether there are differences in CPUE's and medium sizes depending on the tides of three species, Thryssa vitrirostris, Sillago sihama and Sardinella albella. Results show that there are significant differences in catch... |
