초록

대하, Fenneropenaeus chinensis의 난소 성숙에 대한 serotonin(5-hydroxytryptamine, 5-HT), ecdysone(20-hydroxyecdysone, 20-E) 그리고 HCG(human chorionic gonadotropin)의 효과를 조사하였다. 대하에 5-HT(체중 g당 ), 20-E(체중g당 ) 그리고 HCG(체중 g당 5 IU, 10 IU)를 5일 간격으로 3회 주사한 후 10일이 더 지난 시점에 채집하

The effects of serotonin (5-hydroxytryptamine, 5-HT), ecdysone (20-hydroxyecdysone, 20-E) and HCG (human chorionic gonadotropin) on the ovarian maturation of the fleshy shrimp, Fenneropenaeus chinensis were investigated. Adult female fleshy shrimps were injected with 5-HT (/g body weight (BW) or /g BW), 20-E (/g BW, /g BW or /g BW) or HCG (5 IU/g BW or 10 IU/g BW) three times at 5-day intervals and were sacrificed 10 days after the last injection. The effects were compared against an intact control group and sham control group which received the injection of sterile saline solution as a vehicle. 20-E and HCG showed no effectiveness on ovarian maturation in fleshy shrimps. However flesh shrimp given 5-HT of /g BW showed significant increase in gonadosomatic index (GSI) in early spring. The results suggest that treatment of 5-HT of /g BW or more is useful approach for the nursery production of the fleshy shrimp, Fenneropenaeus chinensis aquaculture.
