Initial efforts to cultivate abalone were done in Japan (Ino 1952) and a major program to seed juveniles in the ocean was underway by the early 1970s. Buzz Owen and his... associates at the Pacific Mariculture shellfish hatchery at Pigeon Point near San Francisco, was successful in cultivating the red abalone and several hybrid combinations with other...

. Once settled to become postlarvae, young abalone begin to feed on smaller elements of the microflora (including bacteria and smaller pennate diatoms). Development rate and length... of the swimming larval period are markedly influenced by temperature. Larvae of the temperate species, the green abalone, cultured at its optimum 22--24 o C, reach settling maturity... in as few as 3.5 days. The cold water red abalone, at its optimum 14--16 o C, may reach settlement in five days (Leighton 1974).Juvenile green abalone reared at 24--26 o C have...
