Induced maturation and spawning of domestic and wild striped bass, Morone saxatilis (Walbaum), broodstock with implanted GnRH analogue and injected hCG
Aquaculture and Fisheries Management, 24(3), 389.
TL;DR:
Using the combined mGnRHa implant-hCG injection technique, fry production rates were comparable to those obtained using fully mature wild females taken directly from their spawning grounds.

Abstract. A domestic striped bass. Morone saxatilis (Walbaum), broodstock was established by rearing fish to sexual maturity in ponds. A method was developed to reproduce the domestic females, and also wild females too immature to be successfully induced to spawn with injected human chorionic gonadotropin (hCG). The fish were implanted with pellets containing 100–150μg of a synthetic analogue of mammalian gonadotropin reieasing-hormone, [D-Ala6- Pro9-NEt]-LHRH (mGnRHa), in a matrix of cholesterol (CH) and cellulose. They were implanted with one fast hormone-release (80% CH) pellet and one slow hormone-release (95% CH) pellet and allowed to mature for 1–3 days, until they entered the process of final oocyte maturation and were induced to ovulate or spawn with an hCG injection. The secondary hCG injection was found to be necessary to speed the maturation of the wild fish; they otherwise would succumb to the stresses of capture, handling and confinement before they could be spawned. The total mGnRHa dosages used ranged from 33 to 111μg mGnRHa/kg body weight, and the hCG doses were either 165 or 330 IU hCG/kg body weight. Using the combined mGnRHa implant-hCG injection technique, fry production rates were comparable to those obtained using fully mature wild females taken directly from their spawning grounds.
