[2] Temperature plays a key role in the timing of spawning and larvae settlement of the Yesso scallop.

It was found that the timing for the commencement of spawning is shifted to a later date when the surface temperature of the water remains below 0°C for a prolonged period.

In addition, lower temperatures throughout April could potentially influence the onset timing of scallop spawning.

The commencement of the Yesso Scallop larvae settlement is typically between June 4 to July 5 over the period of 15 days.

Consequently, it was established that the Japanese scallop Mizuhopecten yessoensis experiences the lowest mortality rate between the age of 2 and 5.

[5]The main predators of the Yesso scallops are the sea stars Asterias amurensis and Distolasterias nipon.
