Drug Research Information Bulletin - Efficacy of cGnRH IIa to Induce Spawning in Female Channel Catfish Ictalurus punctatus

The use of hormones to induce spawning in fish is critical to the success of many fisheries and aquaculture programs. A wide variety of programs are dependent upon hormone treatment to complete final gamete maturation and ensure successful spawning. Spawning is a stressful period for all fish species. The handling required during the spawning of fish for artificial propagation complicates an already delicate situation. During normal spawning operations at a hatchery, it may be necessary to handle and examine individual fish weekly over a 6 – 8-week period. Such procedures can be extremely stressful to valuable broodstock broodstock
