  • Balssaxius habereri (Balss, 1903) has been newly reported in Korean waters. This species was previously known from the Pacific coast of northern Japan, Korea Strait, Yellow Sea, and Japanese coast of the East Sea. Specimens were collected from western Jeju Island using otter trawls at depths of 65-85 m. Regarding Korean axiid shrimps, a single species, Boasaxius princeps (Boas, 1880), previously known as Axiopsis princeps in Korea, has been recorded. B. habereri is easily distinguished from B. princeps as it does not have tufts of setae on its body and males do not have the first pleopod. Morphological descriptions and color photos of the specimens are provided.

  • This study was performed to investigate the antimicrobial effects of hetero-chitosans and their oligosaccharides on the halophilic bacterium, Vibrio parahaemolyticus. Nine classes of hetero-chitosan oligosaccharides were prepared based on their molecular weights, using an ultrafiltration membrane reactor system with chitosanase and celluase, from partially different deacetylated chitosans, 90%, 75%, and 50% deacetylated chitosan, respectively. Thirty-two strains of V. parahaemolyticus were isolated from various marine organisms such as shellfish, shrimps, octopus, and seabirds. Seventy-five percent deacetylated chitosan showed the highest antimicrobial acitivity. The minimal inhibitory concentration (MIC) was 0.5 mg/ml on 14 strains of V. parahaemolyticus, and MIC of the rest strains (18 strains) was 1.0 mg/ml. In addition, MIC of most hetero-chitosan oligosaccharides was 8.0 mg/ml. The results revealed that the antimicrobial effects of hetero-chitosans and their oligosaccharides against V. parahaemolyticus depend on the degree of deacetylation, their molecular weights, and strains tested.

  • The southern rough shrimp, Trachysalambria curvirostris (Stimpson 1860) (formerly known as Trachypenaeus curvirostris) occur in the East China Sea, Korea and Japan to China(Kubo, 1949; Paulinose, 1982), and is locally abundant species in the coastal areas of Korea(Kim, 1997). The main investigations into diets of shrimps have been on the Penaeidae(Chong & Sasekumar, 1991; Wassenberg & Hill, 1993), Crangonidae(Pihl & Rosenberg, 1984; Allen, 1966; Boddeke et at., 1986).

  • The palaemonid shrimp Exopazaemon modestus inhabits the freshwater of the Indo-West Pacific, Siberia, Manchuira, Korea, China, Taiwan (Holthuis, 1980) and is abundant in the fresh water areas of southwest of Korea. Palaemonid shrimps are adapted to a variety of habitats in freshwater, brackish and marine environments. They play important role in the ecosystem of fresh, brackish and marine waters, acting as predators feeding on algae, detritus, crustaceans and meiofauna (Bell and Coull, 1978) and in turn, as preys for fishes and other predators (Anderson, 1985).

  • Many people living in Asia countries, particularly Korea, Japan and China, have consumed very widely fresh seafood products, such as shrimps, oysters, mussels and other marine invertebrates and fishes, without any heating or cooking. A variety of Vibrio spp., including V. parahaemolyticus, V. cholera. V. vulnificus, and V. fluvialis, lives in these seafoods and cause great problems associated with human disease. A strong antimicrobial agent to effectively inhibit the growth of these pathogenic bacteria in in vivo or in vitro is urgently need for preventing fish and human diseases. (omitted)

  • Fourteen species of the family Penaeidae have been previously reported from the Korean waters (Kim, 1977: Cha et al., 2001). Recent collections from the coastal waters of Korea revealed the presence of two penaeid species, Metapenaeopsis lata Kubo, 1949 and Parapenaeopsis cultrirostris Alcock, 1906. These two species have been reported from Japan, East China Sea and Sou China Sea, and the Indo-West Pacific low South China Sea. We present brief notes of these species as two new members of the Korean fauna. (omitted)

  • The feeding ecology of Doederleinia berycoides from the southern sea of Korea was examined. Specimens were caught monthly from January 2007 to June 2008. The size of the specimens ranged from 6.8 to 39.8cm in total length (TL). The primary prey items of D. berycoides included fishes and shrimps. In autumn, feeding mainly crustacea and fishes feeding mainly in winter. The individuals of smallest size class (less than 15 cm TL) fed mainly on crustacea. The proportion of crustacea decreased as body size increased, whereas the consumption of fishes increased. Fishes accounted for almost (86%) stomach contents of larger individuals (more than 35 cm TL).

  • We examined the sex ratio, and insemination rate of Parapenaeus fissuroides and Parapenaeus lanceolatus using samples collected near Cheju Island, Korea, in January 2005. Females were more numerous than males in both species, and based on the gonad color pattern, sex ratio, and insemination rate, the spawning period of these shrimps was determined to be during winter.

  • A taxonomic study for clarifying the decapod fauna of Gejedo Island, Korea was performed. Seventy nine species in 28 families were identified through the present investigation and of which 9 species of shrimps, 7 species of anomurans, and 39 species of crabs are newly added to the decapod fauna of this area. With the previously known 40 species, a total of 93 decapod species from this island and its adjacent islets are listed, and Pugettia quadridens intermedia Sakai, 1939 is redescribed with illustrations. The zoogeographical aspects of Geojedo Island are also discussed based on the composition of geographical forms of brachyuran decapods.
