Abstract

For the aquaculture industrialization of surf clam (Tresus keenae), it is important to basic data on the marine environment of the habitat of surf clam (T. keenae). In this study, we investigated the marine environment of habitat of surf clam (T. keenae) and sought to basic data for the preparation of surf clam (T. keenae) for artificial seed production. The water temperature of the habitat of surf clam (T. keenae) was the lowest in winter and appeared high in summer. The salt concentration showed it range from 31.2 to 33.9 psu. The pH showed it range from 7.69 to 8.70, with high pH in winter and low pH in summer. The dissolved oxygen(DO) was showed it range from 6.20 to 10.24 mg / L and the autumn was relatively higher than the spring and winter. The species composition of phytoplankton was about 30 to 40 species, and most of them were diatoms. The abundance of seasonal phytoplankton showed it range from 23.5 to 61.3 cells / ml, showing seasonal differences. The expression of dominant species also showed a difference depending on the season. As for the particle size composition of the sediment, sandy silt was the most distributed. Flow velocities appeared at 50-80 cm / s in the southeast direction at ebb tide and at 60-100 cm / s in the northwest direction at flood tide. The results of this study can be used as basic data for providing knowledge about the habitat and marine environment of surf clam (T. keenae) and for studying shellfish that inhabit the sedimentary layer.

왕우럭조개 양식산업화를 위해서는 왕우럭조개 서식지의 해양환경에 관한 기초자료 확보가 중요하다. 본 연구는 왕우럭조개 서식지 해양환경을 조사하여 인공종자생산을 위한 왕우럭조개 모패의 준비에 대한 기초자료를 확보하고자 하였다. 왕우럭조개 서식지의 수온은 겨울철에 가장 낮았으며, 여름철에 높게 나타났다. 염분은 31.2 ~ 33.9 psu로 조사시기에 따라 큰 차이가 없었다. pH는 7.69 ~ 8.70으로 겨울철에 높고, 여름철에 낮았다. 용존산소는 6.20 ~ 10.24 mg/L의 범위로 가을철이 봄철 및 겨울철에 비해 상대적으로 높게 나타났다. 식물 플랑크톤의 종 조성은 계절에 따라 약 30 ~ 40종 정도로 규조류가 대부분이었다. 계절별 식물플랑크톤 현존량은 23.5 ~ 61.3 cells/ml로 계절마다 차이를 보였다. 또한 우점종의 출현도 계절마다 차이를 보였다. 퇴적물 입도 조성은 모래 실트(sandy silt)이었다. 조류의 유향과 유속은 낙조시 남동방향으로 50 ~ 80 cm/s 나타났으며 창조시에는 북서방향으로 60 ~ 100 cm/s로 나타났다. 본 연구의 결과는 왕우럭조개의 서식지 해양환경에 대한 지식의 제공 및 잠입 서식하는 패류의 연구에 기초자료로 활용이 가능하다 사료된다.
