Although shrimps belonging to family Crangonidae are known to be genetically divergent and ecologically important among the various benthos, any of their mitochondrial genome has not been reported yet. We here determined the complete mitochondrial genome sequence of Crangon hakodatei (Rathbun, 1902), which was collected from East China Sea ($124^{\circ}E$ and $34.5^{\circ}N$). Total mitochondrial genome length of C. hakodatei was 16,060 bp, in which 13 proteins, 2 ribosomal RNAs, 22 transfer RNAs and a putative control region were encoded. Secondary structure prediction analysis showed that twenty tRNA genes exhibit the conserved structure but two genes, $tRNA^{Cys}$ and $tRNA^{Ser}$ (AGN), lack T and D arm, respectively. Based on the sequence similarity of the COI region from the currently reported five species belonging to genus Crangonidae, C. hakodatei was most closely related to Crangon crangon. Phylogenetic analysis of full COXI genes belonging to infraorder Caridea showed that only crangonid shrimps were clustered together with those of Dendrobranchiata. Gene order were well conserved from Penaeoidea to Caridea but $tRNA^{Pro}$ and $tRNA^{Thr}$ in Palaemonid shrimp were flipped each other by the recombination. Further study about mitochondrial genome sequences of shrimps belonging to Crangonidae should be made to know better about their evolutional relationships with other those in infraorder Caridea.

The feeding habits of pacific cod (Gadus macrocephalus) were studied by analyses of stomach contents. Specimens of G. macrocephalus (n=407) were collected from the western coastal waters of Korea, monthly from July 2017 to June 2018. The size of G. macrocephalus ranged from 30.4 to 86.0 cm in total length (TL). G. macrocephalus was consumed mainly Pisces (71.5%) and Caridea (24.2%) based on % IRI, whereas other prey items including, Paguroidea, Euphausiacea and Cephalopods showed a low contribution to the diet. The feeding ratio of Caridea decreased with increasing fish size. While this decrease paralleled the increased consumption of fish preys. The feeding ratios of Pisces were the highest during spring, autumn and winter, whereas the proportion of Caridea was higher in summer.

The first zoeal stage of Heptacarpus rectirostris (Stimpson, 1860) is re-described and illustrated in detail from laboratory-hatched material. The first zoea of H. rectirostris is more closely related to that of H. futilirostris than to H. camtschaticus, H. pandaloides, and H. geniculatus by having the pterygostomial spine and two anteroventral denticles on the carapace. The former two species, however, can be readily distinguished by the presence (H. futilirostris) or absence (H. rectirostris) of the posterolateral spine on the abdominal somites 4-5. A provisional key to the first zoeas of Heptacarpus for which larval studies are known from Korea and adjacent waters is provided. A list of larval descriptions within the Hippolytidae from Korea and adjacent waters is also included.

The first zoeal stage of Palaemon ortmanni (Rathbun, 1902) is re-described and illustrated in detail from laboratory-hatched material. The first zoeas of Palaemon are more closely related to those of Palaemonetes than to Macrobrachium, Leptocarpus, Leander, Leanderites, and Brachycarpus by having the endopod of maxillule with terminal seta and the endopod of maxilla with 2+1 setae. A provisional key to the zoeas between three genera Palaemon, Macrobrachium, and Periclimenes known from Korean waters is included.

As a result of taxonomic study on shrimps collected from Korean waters, one species of the snapping shrimp turned out to be new to Korean fauna. Synalpheus neomeris is redescribed and reported for the first time from Korea.

Nine zoeal stages of Lysmata vittata (Stimpson, 1860) are described from laboratory-reared material. The ornamentation of the carapace and the fifth abdominal somite readily distinguish the first zoeas of L. vittata from the two previously known first larvae of Lysmata (L. anchisteus and L. seticaudata). Larval characters of the genus Lysmata are summarized. The setation of 1,2,3(6) on the basis of the second maxilliped indicates that Lysmata is closely related to Exhippolysmata.

The alpheid shrimps collected from Jejudo Island turned out to be a species belonging to the genus Prionalpheus which is an unreported genus from Korean waters. In this paper, Prionalpheus sulu is reported for the first time from Korean waters with description and illustration.
