RELATED:
[California] [M. californianus] spawned after shock treatment (scraping or byssus puling; found effective in air and under water), being exposed to gametes from crushed gonads (most effective when both male and female gametes present); stimuli more effective when repeated; stimuli more effect when mussels are grouped instead of isolated; temperature stimuli were inconclusive. Wave action, exposure to air, or pull of a starfish hypothesized to stimulate spawning (Young 1945)
Reproduction Time:
[Sea of Japan] Gametes mature in late July to early August. Spawning season started in mid-August and continued until mid-September (Kulikova et al. 2011)
[Korea] spawning season begins in late spring, when the temperature is 20-25ºC (Shen & Teng 2009, cited in Kulikova et al. 2011)
