Feeding habits of Kammal thryssa Thryssa kammalensis (Bleeker, 1849) in the coastal waters of Gadeok-do, Korea

다국어 초록 (Multilingual Abstract)

The feeding habits of Thryssa kammalensis was studied using 430 specimens collected from October 2010 toSeptember 2011 in the coastal waters of Gadeok-do, Korea. T. kammalensis in the coastal waters of Gadeok-dowas carnivorous predator and planktonic feeder with a wide variety of prey items such as arrowworm,copepods, crab larvae, shrimp larvae, and fish eggs. In addition, T. kammalensis consumed mainly arrowworm,copepods, crab larvae, shrimp larvae, fish eggs, and the diet also included small quantities of cladocerans,amphipods, bivalve larvae, mysids, and euphausiids. On the other hand, the body length (BL) of T. kammalensisspecimens ranged from 5.9 to 15.1 cm. Size-related variations in dietary composition of T. kammalensis werenot significant that overlap indexes of each major food items that showed very high values in all size classes,representing more than 0.80. Arrowworms were the dominant prey item in all sizes, and copepods were thenext most frequent prey item consumed in all size classes. Seasonal changes in dietary composition ofT. kammalensis were significant. However, overlap indexes of each major food items in some season showedvery high values of 0.80 (between spring and winter) and 0.85 (between summer and autumn). Copepods weremost frequently eaten in the spring and winter. Moreover, arrowworm were the dominant prey item in summerand autumn. Mean numbers of prey per stomach (mN/ST) changed significantly with size groups (P < 0.05),but mean wet weight of preys per stomach (mW/ST) showed an opposite tendency (P > 0.05).
