内容記述 | LH-RH cholesterol pellet formulated for a long delivery was administered to female Ayu, Plecoglossus altivelis which were maintained at ovarian maturation-suppressive condition of the long photoperiod (15L: 9D). Two types of hormone such as native LH-RH and des-Gly10 [D-Ala6]-LH-RH ethylamide (LH-RH ethylamide) were used in this study. In experiment I (native LH-RH), the initial control fish with an early phase of yolky oocytes showed an atrophy of ovary at the end of experiment, whereas the fish treated with LH-RH at a level of 100 µg showed acceleration of ovarian maturation and ovulation in some fish. All the fish received LH-RH 200 µg overcame against the ovarian maturation-suppressive condition and ovulated within 32 days. In experiment II (LH-RH ethylamide), the initial control fish with non-yolky oocyte showed a slight increase of GSI, whereas the fish treated with LH-RH ethylamide at a level of 50 or 100 µg ovulated within 53 days. Furthermore, LH-RH ethylamide was more potent in inducing maturation and ovulation of Ayu than native LH-RH. Consequently, LH-RH cholesterol pellet was demonstrated a longly active effect for yolk formation, final maturation and ovulation of fish held under the ovarian maturation-suppressive condition. | |||||||||
