This study was carried out to investigate the environmental quality and the growth of transplanted pen shell, Atrinna pectinata japonica. Followings are the results of growth of transplanted pen shell with respect to the shell size groups from the natural habitat (Usando) in May 1995, and cultivated upto November in the transplantated area (Soomoonri).
The water depth of transplantated area and natural habitat were 3 m, 20~25 m, respectively. The seawater temperature of the two culturing farms were ranged of 10.9~27.8℃, 8.5~30.0℃, respectively at the lowest in November and the highest in July. The seawater salinity of the two areas were ranged of 29.54~35.26‰, 28.75~36.31‰, respectively at the lowest in July and the highest in November. The phosphoric acid (PO₄-P) of the two areas were 0.09~1.14 ㎍-at/ℓ, 0.23~1.33 ㎍-at/ℓ, respectively at the lowest in June and the highest in September. The bottom type of the two areas was a silty mud, 85.23% (82.17~87.26%) in natural habitat and 92.12% (90.76~92.94%) in transplanted area. In this study area, phytoplankton were composed of 19 species. Of these 19 species, Skeletonema costatum was dominant species in seawater between natural habitat and transplantatied area, and 157 cells/㎖, 165 cells/㎖ at August respectively. Stock of phytoplankton in transplantated area were more than those of natural habitat except June and November.
The growth of shell length, shell height, total weight, soft part weight and posterior adductor muscle weight of pen shell on different size groups(SL 10, 10~15, 15~20, 20 cm) were excellent in shell length of 10 cm group, and 99.32%, 107.66%, 871.09%, 951.26% and 1,223. 76%, respectively. The survival rate of pen shell was 98.10% in the shell length of 10 cm groups, 90.35~94.76% in the others groups.
The growth of shell length, total weight, soft part weight and posterior adductor muscle weight of pen shell in transplantated area were more 1.3, 2.6, 2.7 and 4.5 times than those of natural habitat.
