Reproductive efficiency of turbot (Scophthalmus maximus L.) females treated with LHRHa
A broodstock of 25 females with different maturity stages were induced to spawn with a single, dosis of 3. pg/Kg .of LHRHa. A response was experienced by 100% of the most advanced females (stages II arid III). The less advanced females (stages 0 and 1) were induced again two weeks later; using the s...
