Abstract

Turbot (Scophthalmus maximus L.) reared in captivity suffer a hepato-renal syndrome, one of the characteristics of which is, on the basis of histological evidence, calcification of the renal tubules. The concentrations of calcium, magnesium and phosphorus were therefore compared in the kidney, the serum, and ultrafiltrates of the serum of wild turbot and of turbot reared in captivity at two separate sites. No differences in renal calcium, magnesium and phosphorus levels were found. Renal calcium levels were normal, being comparable to those found in other marine and freshwater fish. Serum from wild turbot contained significantly higher concentrations of both total and ultrafilterable magnesium than did serum from turbot reared in captivity. Less of the serum calcium of wild turbot was ultrafilterable than was the serum calcium of captive turbot. No other differences in serum levels of these elements were found between wild and captive turbot. The analyses do not suggest any relationship, either causal or indirect, between the hepato-renal syndrome and a disturbance of calcium/magnesium metabolism.
