In turbot larvae, Scophthalmus maximus , deprived of food for 24 h there was a significant increase in the specific surface of the epithelium and the corresponding microvillous border of the foregut accompanied by slight cellular degeneration. Following 48 h starvation Sarvae showed severe tissue degeneration in the foregut mucosa, progressing to extensive mucosal desquamation and cellular sloughing. Intracellular vacuolation of the epithelium and loss of microvilli was also extensive and the ability of the gut to absorb food must be severely impaired, with further starvation probably resulting in larval death. There was no evidence of parasitic infection in any of the larvae sampled and all observed alterations are attributable to food deprivation.
