영문 초록

This study was conducted to develop the effective seeding production of Korean aucha perch, Coreoperca herzi. Time need for hatching and survival rate of fertilized eggs, growth and survival rate of the larvae and juveniles reared at different water temperatures(18.0±0.5℃, 21.0±0.5℃, 24.0±0.5℃) and rearing densities (300, 600, 900 ind./160ℓ) were investigated. And also, growth and survival rate of Korean aucha perch juveniles fed experimental diet(compound meal+Artemia nauplius+Daphnia sp.; Artemia nauplius+Daphnia sp.; compound meal) were determined. The required time for hatching and hatching rate of eggs after insemination in different water temperatures were 400~412 hours(98.5%) at 18.0±0.5℃, 288~296 hours(95.4%) at 21.0±0.5℃, 218~237 hours(87.4%) at 24.0±0.5℃, respectively. The fastest growth of fingerings reared at different water temperature were obtained at 24.0±0.5℃ followed by 21.0±0.5℃, 18.0±0.5℃ and the highest survival rates were 82.5%, 70.2% and 60.5%, respectively. The growth and survival rates of larvae for 100 days were 50.5±1.0㎜, 90.5% at 300 ind./160ℓ group, 43.5±1.0㎜, 75.5% at 600 ind./160ℓ group and 41.3±1.0㎜, 63.2% at 900 ind./160ℓ group, respectively. In the groups of Korean aucha perch, Coreoperca herzi fed the experimental diet, the highest growth and survival rate was shown in mixture of compound meal, Artemia nauplius and Daphnia sp. feeding trial group.
