  • The present study reports mysids on sandy beaches along the eastern coast of Korea. Samples were collected with a dip net or a sled net in sandy shores in April 1995 and November 2006. 9 species representing five genera were identified from the present study. Of these, the genus Nipponomysis including N. lingvura, N. ornata, and N. imparis, and Acanthomysis nakazatoi were newly recorded from the Korean waters. Morphological descriptions and taxonomic key to species were given. The present study reports that 45 species belonging to 15 genera from the Korean waters have been recorded.

  • A mysid, Neomysis awatschensis(Brandt), which distributes abundantly in brackish lakes, estuaries and salt marshes along the southern and western coast of Korea, from Kimhae to Inchon is described and recorded as new to Korea. The world distribution of the species are also revised with short discussion.

  • In crustacea the molting cycle is the most important physiological process affecting growth, behaviour, reproduction and population dynamics through their life span. Particularly molt cycle is closely related to reproductive cycle, and it is important to determine the successive stages of molt cycle to understand reproductive phenomena including ovarian cycle and the development of the embryos in the marsupium.

  • Ovarian cycle, marsupial development and molt cycle of Archaeomysis kokuboi were studied to understand these processes as a whole event. Based on morphological characters the marsupial development is divided into 3 stages, Embryonic stage (duration time of 4 days), Nauplioid stage (5 days) and Postnauplioid stage (4 days). Morphological description was ma de for the 3 stages, and each stage was examined in relation to the corresponding stages of ovarian cycle and molt cycle.

  • The diet of the walleye pollock Gadus chalcogrammus, was studied by examining the stomach contents of 864 individuals. Using gill nets, samples were collected monthly from January to December 2017 in Jugwang, Sokcho, Yangyang, Uljin, Ganggu, and Gampo, Korea. The specimens ranged in total length (TL) from 16.6 to 75.2 cm. G. chalcogrammus fed mainly on Euphausia pacifica (Euphausiacea) and less on Cephalopoda, Pisces, Mysidacea, and Macrura. The results indicated that G. chalcogrammus is a specialist feeder, feeding mainly Euphausiacea. With growth, however, its diet shifted from Euphausiacea to Cephalopoda, Macrura and Pisces. Smaller individuals (<40.0 cm TL) consumed mainly Euphausiacea. The proportion of Euphausiacea decreased with increasing body size, whereas the consumption of Cephalopoda and Macrura increased gradually.

  • Stomach contents of hairtail, Trichiurus lepturus collected in the Nakdong River Estuary were examined quantitatively. T. lepturus was a carnivore which consumed mainly fishes, crustaceans (such as copepods, euphausiids and shrimps) and chaetognaths. Its diets included small quantities of small squids. T. lepturus showed ontogenetic progression of three feeding stages : an initial feeding stage was a planktivorous stage in which copepods were the major food item, followed by a mixed feeding stage in which euphausiids, mysids, shrimps, chaetognaths and fishes were the major food items, and finally a piscivorous stage in which fishes were the major food item. Especially anchovies were heavily selected by large T. lepturus.
