The effects of water temperature and hormone treatments on circulating LH and ovulation in tench (Tinca tinca)

Popis výsledku v původním jazyce

The effectiveness of three hormone treatments commonly used for artificial reproduction of tench was evaluated under three thermal regimes, with focus on the need for dopamine antagonist. Mature females were divided into nine groups (n = 8) and graduallyexposed, over a 24 h period, to three temperature regimes: cold (18.1 +/- 0.02 degrees C), optimal (22.05 +/- 0.03 degrees C), and warm (26.3 +/- 0.01 degrees C). Each temperature regime comprised three experimental groups injected with one of three hormone treatments: carp pituitary extract (CPE; 3 mg kg(-1)); [D-Arg(6), Pro(9), NEt]-sGnRH (10 mu g kg(-1)); and [D-Arg(6), Pro(9), NEt]-sGnRH (10 mu g kg(-1)) + metoclopramide (20 mg kg(-1)) (combined treatment). No differences were found between ovulation induction (ovulation rate }= 75 %) with sGnRHa alone and with the combined treatment; whereas CPE at cold and warm water temperatures was significantly less effective (P { 0.05) than above mentioned treatments. Administration of sGnRHa
