초록
This study was performed to examine the influence of water temperature on egg developmental speed for determining the required time and optimum water temperature for hatching of olive flounder Paralichthys olivaceus eggs. The fertilized eggs were collected from the naturally spawned adults in November 2007. The eggs were randomly divided into 6 groups of temperature (5, 10, 15, 20, 25 and 30℃) and transferred in 1ℓ beaker, respectively. The fertilized eggs of the olive flounder did not hatched at 5℃ and 30℃ and hatching rates at 10, 15, 20 and 25℃ were 3, 12, 25 and 50%, respectively. The relationships between the water temperature (T, ℃) and required time (1/t, hour) from egg to each developmental stage were given as follows ; Blastula: 1/t=0.0208T?0.0951 (r2=0.8593)Kupffer's vesicle: 1/t=0.0052T?0.0176 (r2=0.9819)Myotome: 1/t=0.0034T?0.0172 (r2=0.8508)Hatching: 1/t=0.0016T?0.0068 (r2=0.9915) Biological minimum temperature in egg development was calculated to be 4.3℃.
Abstract
This study was performed to examine the influence of water temperature on egg developmental speed for determining the required time and optimum water temperature for hatching of olive flounder Paralichthys olivaceus eggs. The fertilized eggs were collected from the naturally spawned adults in November 2007. The eggs were randomly divided into 6 groups of temperature (5, 10, 15, 20, 25 and 30℃) and transferred in 1ℓ beaker, respectively. The fertilized eggs of the olive flounder did not hatched at 5℃ and 30℃ and hatching rates at 10, 15, 20 and 25℃ were 3, 12, 25 and 50%, respectively. The relationships between the water temperature (T, ℃) and required time (1/t, hour) from egg to each developmental stage were given as follows ; Blastula: 1/t=0.0208T?0.0951 (r2=0.8593)Kupffer's vesicle: 1/t=0.0052T?0.0176 (r2=0.9819)Myotome: 1/t=0.0034T?0.0172 (r2=0.8508)Hatching: 1/t=0.0016T?0.0068 (r2=0.9915) Biological minimum temperature in egg development was calculated to be 4.3℃.
