Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Body almost circular. Eye side without scales but with large bony tubercles (Ref. 35388).

Adults live on sandy, rocky or mixed bottoms; rather common in brackish waters. Feed mainly on other bottom-living fishes (sand-eels, gobies, etc.), and also, to a lesser extent, on larger crustaceans and bivalves. Batch spawner (Ref. 51846). Spawning season is between April and August; pelagic eggs. May reach 25 kg (Ref. 9988). Highly esteemed food fish. Utilized fresh or frozen; eaten steamed, pan-fried, broiled, boiled, microwaved and baked (Ref. 9988).

Life cycle and mating behavior Maturities | Fortpflanzung | Spawnings | Egg(s) | Fecundities | Larven

Spawning usually happens between the months of February and April in the Mediterranean and from May to July in the Atlantic. Sequenced spawning every 2-4 days. Eggs have a single fat drop. Larvae are initially symmetric but, at the end of the metamorphosis (day 40-50, 25 mm), the right eye moves to the left side, losing its initial bilateral symmetry. Egg size 0.9 - 1.2 mm, larval length at hatching 2.7-3.1 mm.
