Breeding Season

They mate sometime between midsummer and the month of December. This is the best time for the herrings to spawn. Herring fish become sexually mature when they are around four to nine years old.

Breeding

The eggs are deposited on rocks or seaweed. It generally takes about fourteen days to hatch. The young ones normally reach adulthood in about four years. Herrings travel towards the shore to spawn between the months of December and July. The female deposits as many as forty thousand eggs on seaweed and rocks.

Fertilization is external. Female Herrings releases eggs and male herrings release lots of milt at the same time. The Herrings become fat prior to spawning, because they feed on the spring blooms of plankton offered up by temperate waters of the Gulf. Mature eggs make up most of the portion of the female’s body mass. The fertilized eggs hatch into larvae in seven to ten days depending on the temperature of the water.

Lifecycle

The larva swims towards the surface. Herrings become sexually mature when they reach the age of two to three years. Baby Herrings gain diet from autumn coastal blooms. They are often hastily snatched away from the sea by diving birds like guillemots.

The larvae are about 5 to 6 millimeters long at hatching, with a small yolk sac which gets absorbed by the time the larva reaches 10 millimeters. The eyes are well pigmented. The rest of the body is almost see-through, close to invisible under water and natural luminance conditions.

Lifespan

They have a life expectancy of 12 to 16 years.

Conservation Status

Atlantic Herring is listed as Least Concern by the IUCN. They are one of the fishes which are abundantly found.
