영문 초록

A hanging and bottom culture experiment of ark shells, Scapharca broughtonii, one of the edible clams, was carried out in Kamark Bay of southern of Korea to find the state of growth and any problems which influence them from May to December 1999. At sampling station, water temperature, specific gravity, pH, DO, PO₄-P, DIN and COD were 10.2~25.8℃, 1.0200~1.0262, 7.71~8.94㎎/ℓ, 0.001~0.015㎎/ℓ, 0.006~0.074㎎/ℓ and 0.40~2.03㎎/ℓ, respectively. And the habitat sediment was composed of mud. Seed shells at an average length of 2.2mm(1.4~3.1mm), height of 1.2mm(0.7~1.3mm) were planted on bottom and hanging May 1999. The growth rate of seeds in bottom was batter then in hanging. For seven months, an average shell length, shell height, shell breadth, total weight of ark shells cultured in hanging attained to 41.9mm, 32.2mm, 24.5mm and 18.9g, respectively. And an average shell length, shell height, shell breadth, total weight of ark shells cultured in bottom were gained to 63.6mm, 49.6mm, 40.3mm and 67.5g, respectively. It showed that the state of growth was favorable. But the survival rate of seeds in hanging(61.5%) was batter then in bottom(83.7%).
