Turbot

Scophthalmus maximus

  • Family: Turbots – Scophthalmidae
  • Similar species: brill, dab, flounder, plaice
  • Size: 25–40 cm, 0.5–2 kg, occasionally even larger.
  • Appearance: Differs from the flounder in that its eyes are normally on the left side of the head. Body shape also differs, the turbot being almost round but, with fins erect, appears somewhat square. The mouth is much larger than that of other Finnish flatfish and contains sharp teeth. The flatfish closest in appearance to the turbot is the brill, which was first recorded in Finnish waters in 2008. However, brill are not as square in body shape. Turbot are best distinguished from brill by the numerous sharp bony tubercles on the upper (eye) side, these being absent from brill.
  • Colouring: Underside always whitish, upper side dark brown with darker blotches and spots.
  • Reproduction: Spawns around midsummer. The eggs float provided the water has a salinity of at least 0.6-0.7%, spawning thus being restricted to the SW archipelago and south of the Åland islands. The larvae are found close to the surface drifting with the current, and this may have helped turbot to spread to Finnish waters. After metamorphosing they migrate to the bottom, where they remain. In summer turbot inhabit water just a few metres deep among vegetation on a sandy or muddy bottom. They migrate to deeper water (20-30 m) in winter.
  • Food: Bottom-dwelling invertebrates and small fish including Baltic herring, sandeels and gobies.
  • Distribution and habitat: A true seafish, the turbot does not tolerate low salinity as well as the flounder. Found mainly off the SW coast, where it accounts for just 10% of flatfish. Occasionally turns up in the northern Gulf of Botnia and eastern Gulf of Finland.
