1, mussels have the ability to reproduce when they are 3 years old. The spawning season is from May to July. Mussels usually reproduce in the summer, fertilized eggs will develop into larvae in the gill cavity and overwinter, hatching in the spring of the following year. The larvae can be removed by piercing the outer gills with a cottered needle, and then allowed to parasitize the fish for a period of time, the larvae can sink to the bottom of the water to develop and grow.

2. Mature eggs are round and spherical; mature spermatozoa are able to swing their tails and swim when examined microscopically. When the vast majority of eggs in the reproductive nest is mature, the female mussel is ovulated and fertilized. The triangular sail mussel spawns 5 to 8 times a year, with a spawning capacity of 400,000 to 500,000 grains.
