The seaweed community and stomach contents of the dominant herbivorous sea urchins Anthocidaris crassispina and Hemicentrotus pulcherrimus were examined from November 2008 to October 2009, in coastal areas of Tongyeong, Korea. Thirty-five seaweeds including two green, nine brown, and 24 red algae, were found over the study period. Seventeen seaweeds (two green, two brown, and 13 red) and two invertebrates were found in the stomachs of A. crassispina. In H. pulcherrimus, stomach contents were two green, one brown, 11 red seaweeds, and two invertebrates. The shell diameter of A. crassispina and H. pulcherrimus ranged from 22.3 to 62.3 mm and 15.3 to 40.1 mm, respectively. Total body weights ranged from 48.5 to 86.7 g for A. crassispina and from 7.7 to 25.9 g for H. pulcherrimus. The total weight of stomach contents were 5.1 to 25.8 g in A. crassispina and 1.7 to 11.8 g in H. pulcherrimus. The range of gonad weight was 3.6 to 17.0 g in A. crassispina and 0.8 to 4.0 g in H. pulcherrimus. The gonad index (GI) for A. crassispina peaked in July and reached a minimum in December, whereas the GI for H. pulcherrimus was highest in February, and lowest in May.

This study was done to research the effects of temperature on biological evaluation of seawater quality using gametes, embryos and early development system of seaurchin species, Hemicentrotus pulcherrimus, Anthocidaris crassispina and Scaphechinus brevis. As the result of performing effects of temperature on early embryo development, the conditions of appropriate temperature on formation of normal pluteus were appropriate at 5-16$^{\circ}C$ for H. pulcherrimus, 8-2$0^{\circ}C$ for A. crassispina, 12-2$0^{\circ}C$ for S. brevis. The conditions of optimum temperature on biological evaluation were 16$^{\circ}C$ for H. pulcherrimus and 2$0^{\circ}C$ for A. crassispina and S. brevis.

1995년 8월부터 1996년 7월까지 제주도 남제주군 대포리 연안에서 채집한 보라성게의 연령형질 (생식판)로서 성장을 규명한 결과는 다음과 같다. 1. 생식판 (madreporite)에 나타나는 윤문은 2세에서 6세군까지 뚜렷하게 관찰되었다. 2. 각장 (test diameter : TD)과 생식판경 (radius : R)과의 관계식은 다음과 같았다. TD= 22.58R-6.01 (r=0.960) 3. 월별 연변성장율 ($MGR\;:\;(R-r_n)/(r_n-r_{n-1})$)조사에서 추정한 윤문형성시기는 3월에서 5월 사이였다. 4. 각장조성의 월별 성장 경향은 12월에서 이듬해 3월 사이가 주 성장기였고, 4월에서 6월 사이는 성장의 휴지기, 그 외의 기간은 아주 완만한 성장을 하였다. 5. Bertalanffy식이 Gompertz식과 Logistic식보다 잔차 평방합이 적었고, 그 성장식은 다음과 같았다. $$L_t=46.65 (1-e^{-0.283(t+9.210)})$$, $$W_t=44.90 (1-e^{-0.283(t+9.210)})^3$$

This study was attempted to carry out the effects of heavy metals when sea urchins (Hemicentrotus pulcherrimus, Anthocidaris crassispina, Scahhechinus brevis) formed early embryos. Results of the experiment for the effects of heavy metals on the development of sea urchins, in most sea urchins, the ranking of heavy metals according to decreasing effects upon fertilization and development of urchin eggs was follows: Hg, Cu, Zn, CA, Ni, Cr, Pb, As,and Fe. In addition, in most heavy metals, the ranking of experimental animals according to decreasing effects upon fertilization and development of urchin eggs in the same concentration of heaw metals was follows: H. pulcherrimus, A. crassispina, and S. brevis.

This study was conducted to evaluate the effects of pH, using gametes, embryos and early development system of three sea urchins species, Hemicentrotus pulcherrimus, Anthocidaris crassispina and Scaphechinus brevis. As the result of performing effects of pH on early embryo development, the conditions of appropriate pH on formation of normal pluteus were pH 7.0-8.0 for H. pulcherrimus, A. crassispina and S. brevis. Otherwise, the conditions of pH 5.0, pH 6.0, pH 9.0 and pH 10.0 damaged the development of early embryos of each testing animal moderately or strongly.

Effects of five polycyclic aromatic hydrocarbon (PAHs) constituents (naphthalene, fluorine, fluoranthene, benzo(a)pyrene, pyrene) on fertilization and early development of sea urchin egg, sperm and fertilized egg were investigated. The eggs, sperm and fertilized eggs were exposed to several concentrations of PAHs (1, 10, 100, 1000 and 10000㎍/L). The rate of fertilization and hatching decreased when the eggs and sperm were exposed to aqueous solution of PAHs. Also, Exposure of fertilized eggs with each PAHs did decrease survival and hatching rate. Concentration-dependent toxic effects on the rate of fertilization, hatching, survival and abnormality in A. crassispina were observed following exposure to PAHs (1, 10, 100, 1000 and 10000㎍/L). These data show that PAHs exposure decreased in fertilization success of sea urchin egg and sperm and producted abnormal embryo. It is plausible to suggest that PAHs had the potential to significantly reduce coastal recruitment of sea urchin.

다시마(Laminaria japonica)를 기능성 식품소재로 활용하기 위한 예비단계로, 다세포의 다시마를 미립자의 single cell detritus(SCD)로 분해하는 해양세균을 해수, 다시마(Laminaria japonica), 미역(Undaria pinnatifida), 성게(Anthocidaris crassispina), 불가사리(Acanthaster planci), 소라(Batillus cornutus)로부터 분리하였다. 분리한 71개의 균주 중 다시마 조체의 연화능과 알긴산 분해활성을 동시에 가지는 균주는 14개이었으며, 균주 No. 34가 가장 강한 다시마 조체의 연화능과 알긴산 분해활성을 나타내었다. 균주 No. 34는 배양 15일 만에 다세포의 다시마를 미립자의 SCD 형태로 분해하였으며, 그 크기는 $5-10{\mu}m$이었다. 균주 No. 34는 vibrio sp.으로 동정되었으며, Vibrio sp. YKW-34로 명명하였다.
