The effect of a bopyrid isopod Argeia pugettensis, on the growth and reproduction of the Kuro shrimp Argis lar was investigated. A commercial caridean shrimp in the East Sea of Korea, A. lar, was sampled monthly off Pohang with a bottom trawl from July 2009 to June 2011. During the study period, 7,988 individuals were sampled. These shrimp were parasitized by a bopyrid isopod Argeia pugettensis. The overall infection rate was 3.3%, although it declined in the larger size classes. It did not change monthly. The carapace lengths of the host and parasite were positively correlated. There was a significant difference in growth between infested and non-infested shrimp. The infested shrimp also had a lower gonadosomatic index (GSI) and breeding rate. These results suggest that the parasites affected the growth and reproduction of Argis lar.

Bopyrid isopods collected from 35 localities in Korea were examined. Twelve species in 12 genera were identified and classified onto 7 subfamilies, of which following 8 species are new to Korea : Metaboyrus ovalis Shiino, Bopyrissa pyriforma (shiino), Ione cornuta Spence Bate, Parapenaeonella distincta Shiino, Bopyriodes Hippolytes (Kroyer), Pseudostegias dulicilacuum Markham, Athelges takanoshimensis Ishii and Eophrixus shojii Shiino. Athelges japonicus Shiino is found out to be a junior synonym of a.takanoshimensis Ishii. Eight unrecorded scpecies in Korea are descried with figures. Other two species , Apocepon pulcher Nierstrasz et Brender Brandis and Argeia pugettensis Dana. Are provided with figures.
