As a result of this study, the optimum conditions of larval rearing were as follows. The optimum range of water temperature is 20℃ to 24℃, the optimum salinity is 30 psu, the optimum rearing density is 5 ind./ml and the supply of mixed feed organism for larva rearing such as Isochrysis galbana, Chaetoceros simplex and Tetraselmis suecica is 10×104 cells/ml. The results of this study suggest that the optimum conditions of environmental factors in larval rearing of Tresus keenae contribute to productivity improvement through rapid growth and high survival. 강한승,김철원 (사)한국해양생명과학회 상세보기 Cochlodinium polykrikoides 자연체와 배양체의 북방전복과 말쥐치에 대한 유해성 비교 Laboratory exposure tests are helpful for specific clues between harmful algae and marine animals, but have a subject to be answered. That is if the cultured strains are as potent as the wild ones in nature. We tested damage potentials of cultured and wild strains of Cochlodinium polykrikoides to two aquaculture species, abalones Haliotis discus hannai and black scrapers Thamnaconus modestus at 26℃ for 24 hours in culture chamber (80 L) carrying each strain (50 L each) at around 2,000 cells mL-1 and two references, alga-free seawater and Tetraselmis suecica at 10 × 104 cells mL-1. The toxicities were species-specific. They were harmless to the abalone as were two controls. But both were acute to the fish with bigger potential of cultured one. In cultured strain, the fish reached mortality 40% at hour 0.25 and then total mortality at hour 2. The wild one was also damageable but less than cultured one with first and total mortalities at hour 2. All the findings were significant at least at P < 0.05. In the theory of allelochemical dynamics, dinoflagellate toxicity becomes more potent in nutritionally unfavorable waters. In our study, a conspicuous difference between the two strains was length of majority chain, 2-4 cells for cultured one and 8-16 cells for wild one. The shorter chain of cultured strain was reminiscent of the algal growth in less favorable nutrition and of higher production of allelochemicals, and thus might make it more toxic. Our estimation might be worth interpretation in exposure test of harmful dinoflagellates to marine animals. 이상준,한지도,전미애,임창용,손문호,조규태 한국패류학회 상세보기 왕우럭 (Tresus keenae) 치패의 생존 및 성장에 미치는 수온, 사육밀도 및 먹이공급 등의 요인의 영향 This study was conducted to investigate the influence of environmental factors such as water temperature, rearing density, food organism and feeding amount on the growth and survival of spat in surf clam, Tresus keenae. As a result of this study, the optimum conditions of spat rearing were as follows. The optimum range of water temperature is 22℃ to 25℃, the optimum rearing density is 500 ind./cm2 and the supply of mixed feed organism for spat rearing such as Isochrysis galbana, Chaetoceros simplex and Tetraselmis suecica is 50 × 104 cells/ml-100 × 104 cells/ml. The results of this study suggest that the optimum conditions of environmental factors in spat rearing of Tresus keenae contribute to productivity improvement through rapid growth and high survival. 김철원,이영미,전하정,김희린,강한승 한국패류학회 상세보기 코끼리조개 치패의 먹이섭식에 미치는 수온과 먹이생물의 영향 This study was performed to determine the effect of marine algae and water temperature on dietary feeding of juvenile geoduck (Panopea japonica) There was a significant difference on daily feeding efficiency of geoduck depend on temperature. In particular, it was shown that an ingested algal concentration was higher at 10, 15, and 20℃ than 5 and 25℃ for 24 hours. Clearance rate and ingestion rate of geoduck was relatively high at 15℃, showing 30.19 ± 1.06 L/hr/g, 21.83 ± 2.04 × 105 cells/mL, respectively. When two marine algae, Isochrysis galbana and Tetraselmis suecica, were provided to geoduck, there were no significant differences on clearance rate (CR), absorption rate (AR), absorption efficiency (AE) (p > 0.05) However, filtration rate (FR) was high when feeding on T. suecica compare to I. galbana. In conclusion, this study suggests that feeding activity of geoduck is considered to be high at 15℃. In addition, both I. galbana and T. suecica are necessary for geoduck though there was no difference between feeding efficiencies except filtration rate. 손새봄,김기태,남명모,이채성,임현정 한국패류학회 상세보기 -
