속성장 육종 넙치(selected line of olive flounder cultured, SF)의 수정란의 부화율 및 기형률, 자치어의 성장을 일반 넙치(unselected line of olive flounder cultured, UF)와 비교하였다. 동일한 날에 획득한 SF구 및 UF구 수정란의 부화율은 SF구가 96.21.7%, UF구는 90.42.1%로 SF구가 높았으며, 기형률은 UF가 유의하게 높았다. 이들 수정란으로부터 부화한 자어를 8
Hatching rate, larval deformation and growth rate of selected olive flounder (Paralichthys olivaceus) for rapid growth were compared to those of the unselected fish. Fish were spawned on the same day and cultured under the similar conditions. The selected fish had a significantly higher eggs hatching rate, and lower larval deformation. The selected fish grew significantly faster, and at the end of the experiment (8 weeks after hatching) averaged 50.492.67 mm in total length, 16.300.08 mm in body height, and 1.0360.118 g in weight, compared to 40.553.13 mm, 13.500.96 mm, and 0.5570.073 g for unselected fish, respectively. The selected fish had a significantly higher body shape index, however lower condition factor than the unselected fish. The results of the present study demonstrate that the selected fish of the olive flounder for rapid growth had superior growth and improved body shape.
