The four zoeal stages of Alpheus brevicristatus De Haan, 1849 are described and illustrated in detail from larvae roared in the laboratory. The larvae of A. brevicristatus was compared with those of the other Alpheus and a key to the first zoeal larvae of three Korean Alpheus species is provided.

The first larval stage of Neocaridina denticulata sinensis (Kemp, 1918) is described and illustrated in detail. The first larvae of N. d. sinensis are compared with those of four other known congeners of Neocoridina from Asia.

As a result of recent taxonomic study on shrimps collected from Korean waters, one species of the alpheid shrimp turned out to belong to the genus Salmoneus unreported from Korea. Salmoneus gracilipes is redescribed and reported for the first time from Korea.

As a result of recent taxonomic study on shrimps collected from Korean waters, one species turned out to belong to the family Stylodactylidae unreported from Korea. Parastyrodactylus bimuxillaris is redescribed and reported for the first time from Korea.

The first three zoeal stages of fat-handed snapping shrimp Synalpheus tumodomanus (Paulson, 1875) are described and illustrated in detail based on laboratory-reared material. Morphological comparison is made with previous description of S. tumidomanus from Indian waters. Three segmented scale of the antenna and the length of the endopod of antenna readily distinguish the first zoeas of S. tumidomanus from those of S. neomeris, the other known species of the genus Synalpheus from Korea.

Early zoeas of snapping shrimps Alpheus lobidens De Haan,1850 and A. sudara Banner and Banner, 1966 are described and illustrated in detail, based on laboratory-reared materials. A provisional key to the known first alpheid zoeas from Korean coast is provided.

First zoeas of Alpheus albatrossae (Banner, 1953) are described and illustrated for the first time, based on laboratory-hatched zoeas from a female collected in Ulleung-do Island, eastern Korea. The first zoeas of A. albatrossae can be distinguished from those of seven known species of Alpheus (A. brevicristatus, A. digitalis, A. heeia, A. japonicus, A. lobidens, A. richardsoni, and A. sudara) from Korea by having 6-segmented scale of the antenna and the endopod of the first maxilliped with four terminal setae.

The diet of Pacific cod (Gadus macrocephalus) in the East Sea, Yellow Sea and Jinhae Bay was studied by analysis of stomach contents. In total, 518 individuals ranging from 15.5 to 77.0 cm standard length SL were analyzed. Prey organisms of the Pacific cod in the East Sea consistedof Caridea, Cephalopoda and Pisces, whereas In the Yellow Sea, the main food items of Pacific cod were similar to those of East Sea Pacific cod except for Cephalopoda. Interestingly, the stomach contents of Pacific cod in Jinhae Bay is mainly Pisces, which is in contrast to those of the two different coastal areas, the East Sea and the Yellow Sea. Although various species of food were eaten by smaller Pacific cod, both Caridea and Pisces were mainly taken by larger Pacific cod. Consequently, the diet of Pacific cod within acertain size is mainly influenced by prey abundance and prey-size spectrum in its habitat. Higher stomach emptiness of Pacific cod in Jinhae Bay might indicate that fully matured Pacific cod temporally stop feeding during their spawning period.

The diet composition of Tanaka's snailfish, Liparis tanakae were collected by bottom trawl net in the Yellow Sea of Korea during 2022 (April, August, October, and November). The size of the specimens ranged from 3.8 to 52.2 cm in total length. L. tanakae were primary consumed caridea shrimps (Crangon hakodatei, Eualus spathulirostris, etc.) and specialist feeder mainly consumed caridea shirmps (C. hakodatei). The L. tanakae's trophic level is 3.63. Caridea shrimps were the primary prey items for all size groups (<20 cm, 20~30 cm, 30~40 cm, ≥40 cm). The proportion of E. spathulirostris has increased as the body size of L. tanakae increased, whereas the proportion of C. hakodatei decreased gradually. As the body size of L. tanakae increased the mean weight of prey per stomach (mW/ST) tended to increase significantly (One-way ANOVA, P<0.05). The caridea shrimps were the primary prey items throught all seasons. In summer, the main prey items were the C. hakodatei, however, in autumn, the proportion of C. hakodatei decreased while the proportion of E. spathulirostris increased.

The larvae of Palaemon gravieri were reared in the laboratory at three different temperature regimes ($15^{\circ}C,\;20^{\circ}C,\;and\;25^{\circ}C$) with the salinity ranges (28-32 psu) to understand how temperature and body size influence survival rate, and growth components (molt increment and intermolt period). The optimum temperature for the highest survival rate was $25^{\circ}C$. The intermolt periods consistently increased with an increase in size and instar number; however, the molt increments at successive instars generally decreased with an increase in size and instar number. The shortest intermolt period and the highest larval growth rate both occurred at $25^{\circ}C$. Thus, the optimum temperature for larval survival and growth rate was found to be $25^{\circ}C$ which was the temperature at which the larvae actually appear in nature.
