Where do sardines lay eggs?
The edges of the scales on the belly of these fish are rough. These species lay their eggs on the seabed; Atlantic herrings usually lay their eggs at depths of 40–200 m and in some cases intertidally on gravel and small stones and the Pacific herring spawns on seaweed between tidemarks.
What is the life cycle of a sardines?
The life span is divided into seven stages/age classes for anchovy (embryo, early larva, late larva, juvenile, adult age-1 to age-3) and eight stages for sardine (with an additional adult age class: adult age-1 to age-4) (Table 1).
How do sardines mate?
The main breeding area for the Pacific sardines in North America is located off the coast of southern California. The fish reproduce multiple times in a breeding season. Fertilization is external. The eggs and sperm are released into shallow water, where they join.
What predators do sardines have?
