The sea remains calm, but little fishing is done since the fish are spawning.

His letter shows that fish will spawn under most conditions.

The fish spawns several times in a season, sometimes daily for a long period of time.

This may be more frequent when the fish are spawning.

These fish spawn when the water temperature reaches 20 degrees or higher.

The fish loved the change in water conditions and spawned again almost immediately.

For two days nothing happened, but on the third morning I checked the tank and found that the fish had spawned.

These fish only spawn once in a spawning season and produce around 75,000 eggs.

However, it is yet to be seen if the fish will spawn.

These fish spawn in the spring and early summer, from May through August.
