영문 초록

Seasonal fluctuation in abundance and species composition of fish in coastal waters off Samcheonpo were investigated using seasonal samples collected by fish pot and gill net in 2018. During the studying period, a total of 734 fishes were sampled and classified into 26 species, 19 families, and 7 orders. The dominant order was Perciformes accounted for 34.6% of the total fishes.

The Richness index was the highest in September (R=3.887) and lowest in December (R=2.048). The evenness index was the highest in September (E=0.922) and lowest in March (E=0.841). The Diversity index was the highest in September (H′=2.851) and lowest in December (H′=2.125) Furthermore, the dominance index was the highest in December (D=0.447) and lowest in September (D=0.176).
