Analyses sanguines de turbots d'elevage immatures (Scophthalmus maximus L.)

A study of cultured healthy turbot haemochemistry is based on blood data of 107 twelve- to fifteen-month-old fish. Six successive samplings were carried out in the Centre Oceanologique de Bretagne (COB) and in two aquaculture experimental stations in Brittany. Turbot were not fed 36 h before sampling.Thirteen parameters were studied: in the blood, haematocrit and haemoglobin, and in the plasma, glucose, total protein, total cholesterol, triglycerides, phospholipids, sodium, potassium, chloride ion, calcium, magnesium and mineral phosphorus. Moreover, electrophoresis of plasma proteins was systematically carried out. Indicative haemochemistry standards are proposed from these results.A parallel is drawn between the present results and previously known haemochemistry data in turbot and other flat-fish.
