distribution
The thin-lipped mullet can be found in the north-eastern Atlantic from Norway , the North and western Baltic Seas to West Africa in the Senegal area and around the Cape Verde and Canary Islands . It also lives in the Mediterranean and the Black Sea .
Way of life
Mullets live as pronounced schooling fish in the coastal area, where they occasionally invade lagoons and estuaries. In summer, they are mainly found in the surface area and graze on algae and invertebrates near the ground. In winter, they retreat to deeper layers in northern areas and largely stop eating.
The spawning season falls in the Mediterranean from October to December and in more northern areas from March to April. The eggs are released into the open water and float in the surface water due to stored oil droplets. The age of this species can be up to 9 years.
Importance to humans
Mullets are popular food fish that are caught in the open sea and also kept in aquaculture .
