제주도 주변해역에 출현하는 동물플랑크톤의 생물량과 종조성의 시·공간적 변동에 대한 연구를 검토하였다. 동물플랑크톤의 평균 생물량은 근해(50-100㎎/㎥)보다 연안(<50㎎/㎥)이 낮았다. 연안에서 동물플랑크톤의 생물량은 태평양 아열대해역의 생물량과 비슷하였다. 연안의 총 동물플랑크톤(>0.09㎜)에서 몸이 큰 동물플랑크톤(>0.33㎜)이 차지하는 비율이 컸다. 작은 동물플랑크톤(0.09-<0.33㎜)의 생물량은 10-15㎎/㎥이었다. 제주도 연안의 chl.-a농도는우리나라 다른 연안역에 비해 낮았다. Go et al.(1989)이 보고한 것처럼 연안 동물플랑크톤이 높은 생물량에 대한 생산량의 비를 나타낸다면, 저서환경으로부터의 추가적 에너지흐름 경로가 존재할 수 있다. 저서조류기원의 데트리터스는 연안 동물플랑크톤의 중요한영양 공급원이 될 수도 있다고 여겨진다. 또 식물플랑크톤과 데트리터스 소비자로서 연안 동물플랑크톤의 역할을 평가하기 위해서는 몸이 작은 동물플랑크톤과 저서-표영성 동물플랑크톤에 관한 보다 많은 분류 및 생태학적 정보가 필요하다. We reviewed recent studies on estimating the spatio-temporal variability in biomass and species composition of zooplankton around Cheju Island. The average estimated biomass of zooplankton was lower in inshore (〈50 ㎎/㎡), compared to offshore (50-100 ㎎/㎡). The biomass of inshore zooplankton was similar to that of the subtropical Pacific. The large zooplankton (〉 represented a greater portion of total (〉0.09㎜) inshore zooplankton biomass. The average biomass of small zooplankton (0.09-〈0.33㎜) ranged 10-15㎎/㎡. The low concentration of chl. -a appeared in inshore (〈1㎍/1), compared to the other Korean coastal waters (3-6㎍/1). High P/B ratio of inshore zooplankton previously reported by Go et al. (1989) implies the presence of an additional pathway of energy flow from benthic environment. It is assumed that detritus originated from benthic algae may be a significant source of food for inshore zooplankton. In addition, more taxonomical and ecological information on small (0.09-0.33㎜) zooplankton and bentho-pelagic zooplankton is needed to assess the role of inshore zooplankton as consumers of phytoplankton and/or detritus.
Stylocheiron abbreviatum (Euphausiacea, Crustacea): A New Record from the Korean Waters
Suh, Hae-Lip The Korean Society of Fisheries and Aquatic Scienc 2012 Fisheries and Aquatic Sciences Vol.15 No.3
The euphausiid crustacean Stylocheiron abbreviatum G. O. Sars, 1883 has been found in the southern waters of Jeju Island, Korea. This species is the third member of the genus Stylocheiron and the twelfth of the family Euphausiidae identified in Korean waters. Using descriptions of this species, a key to Korean euphausiids is presented.

In February and April 1997, three temporary interruptions of electric power production at the Uljin Nuclear Power Plant in the east coast of Korea were caused by the malfunction of the cool-ing-water supply unit. The clogging of the drum screens inside the unit caused by the surface swarm of the euphausiid Euphausia pacifica Hansen might be responsible for the malfunction. These incidents were of particular interest since such interruption of reactors' operation by krill swarms had not previously been reported. Using samples caught by the drum screens inside the cooling water-supply unit, we investigated the population structure of surface swarms. One occasion of nighttime and three occasions of daytime surface swarms were found in February and April 1997, respectively. The foreguts of more than 60% of E. pacifica in nighttime surface swarm were in full condition. This evidence suggests that E. pacifica aggregates to the surface water at night for feeding. In daytime surface swarms consisting of mature E. pacifica, however, foreguts in full condition were only found in less than 10eio of krill examined, suggesting that daytime surface swarms are closely related to breeding activity. During the study period, the growth rate of mature females was more than twice higher than that of mature males. Analyses of the sex-ratio and length-frequency data show a decrease in the portion of males with increasing size. There was a decline in the number of males of 19 mm in length. Energy loss during spermatophore transfer may result in the death of male E. pacifica, as found in male E. superba.
Morphology of the Gastric Mill of Nyctiphanes australis(Euphausiacea , Crustacea)
Suh, Hae Lip 한국수산학회 1989 한국수산과학회지 Vol.22 No.4
SEM observation revealed that the gastric mill of Nyctiphanes australis consists of paired cluster spines and paired lateral teeth, while the filter-press is absent. The morphology of the gastric mill was extremely constant; the numbers of both setiform processes of cluster spines and serrated spines of lateral teeth increased with increasing body length. The cluster spines of N. australis consisted of a single row of stout setiform processes but the lateral teeth comprised a large projection with small serrated spines. The cluster spines are symmetrical in setiform process distribution, however, the lateral teeth are asymmetrical in number of serrated spines.

Haloptilus caribbeanensis Park, 1970 (Copepoda, Calanoida, Augaptilidae) is redescribed in detail on the basis of an adult female collected from Suruga Bay, Japan. This is the first record of the species from the Indo-Pacific region. Morphology of the Pacific specimen agrees well with that of the Caribbean Sea and Gulf of Mexico specimens, except for the numbers of mandibular teeth. The former has five teeth and the latter six teeth on mandible. The segmentation and segmental aesthetasc numbers of female antennules of H. caribbeanensis are compared with those of five species of Haloptilus (H. angusticeps, H. fons, H. longicornis, H. ornatus and H. spiniceps). These characters show morphological differentiation at the species level. H. caribbeanensis has no aesthetasc on the proximal segments II, IV, and VI of the female antennules.
Phylogenetic Relationships of the Family Metridinidae(Copepoda : Calanoida)
Suh, Hae Lip,Ryu, Ho Young,Susumu Ohtsuka 한국수산학회 1999 Fisheries and Aquatic Sciences Vol.2 No.2
Several differences are revealed in the segmentation and setation of the antennule, maxillule, maxilliped and fifth legs between three genera of the family Metridinidae, Metridia, Pleuromamma, and Gaussia. The phylogenetic relationships are cladistically analyzed on the basis of 10 morphological characters. The cladogram shows that Gaussia and Pleuromamma form a sister group, with Metridia which is the first branch to diverge within the family. The presence of quadritheks on the male antennules of Metridia and Pleuromamma seems to be an important synapomorphy. The loss of quadritheks an Gaussia represents likely evidence of a character reversal into the ancestral condition.

Two species of the poecilostome copepod were recovered in the mantle cavity of the blue mussel, Mytilus galloprovincialis taken from the Yongsan River estuary, Korea. Both species, Pseudomyicola spinosus(Myicolidae) and Modiolicola bifidus(Sabelliphilidae), are new to the Korea fauna.
