Studies on natural populations in England show that sexual maturity is reached at about 4 months (Warren, 1976). However, in other geographical locations, sexual maturity may be reached at 3.5 months (Qian & Chia, 1994). In the laboratory, sexual maturity may be reached between 31 and 48 days after recruitment, depending on temperature (12.6-22 °C) (Tsutsumi & Kikuchi, 1984).
Fecundity has been recorded as 460 eggs per female in Barcelona (Mendez, 1995) to 6-600 eggs per female in USA (Grassle & Grassle, 1974).
Potential longevity ranged from 45 days in Barcelona (Mendez et al., 1997) to 2 years in a population in England (Warren, 1976).
Lopes et al. (2000) found that animals fed on the sea grass Zostera marina had the smallest body size, became sexually mature in the shortest period and had the highest average fecundity. Number of eggs produced from the first spawn was the highest for the individuals fed on the bull kelp Nereocystis luetkeana and the lowest for individuals fed on Zostera marina. Animals fed the green alga Ulva lactuca and the sea grass Zostera marina produced much larger eggs.
