Abalone restocking in the peninsula of Baja California, Mexico, has been practiced for more than 2 decades by fishermen cooperatives. We describe the methods used to produce and release abalone larvae and seeds by these organizations, and provide their recent production statistics. From 2005 to 2011, 2.2 million seeds (>15 mm) and 692 million competent larvae were produced by 6 cooperative hatcheries and released in their fishing grounds. Of these, 90.1% of the seeds and 80.7% of the larvae corresponded to Haliotis fulgens, whereas the figures for Haliotis corrugata were 9.9% and 19.3%, respectively. The research conducted in Mexico on the evaluation of the impact of restocking is also addressed. Preliminary results suggest that less than 5% of the seeds stocked are incorporated into commercial catches.
