The activity of alpha-amylase, glucoamylase, maltase, trehalase, glycogen phosphorylase and trehalose phosphorylase was measured in extracts from larval and adult Hysterothylacium aduncum (Rudolphi, 1802), parasitic nematode of marine fish. The content of glycogen and trehalose in the worm's body was also determined. Both the hydrolytic and phosphorolytic paths of sugar decomposition are present in H. aduncum. In the larvae glycogen was utilised mainly via the hydrolytic path. In the adults the activities of phosphorolytic enzymes were higher than in the larvae. In both stages the activity of trehalose phosphorylase is present. In adult nematodes it is uncommonly high. The dominating sugars in the adults were glucose and glycogen, while in the larvae it was trehalose.

The content of glycogen, glucose and trehalose was measured in larvae and adults of Cystidicola farionis, the parasite isolated from the swim bladder of Osmerus eperlanus from Vistula Lagoon. Activity of glycogen phosphorylase, alpha-amylase, glucoamylase, maltase, trehalase, and trehalose phosphorylase were measured. The highest activity was recorded for alpha-amylase 10.07 +/- 0.97 mu/mg and 7.47 +/- 0.24 mu/mg, next maltase 1.34 +/- 0.63 micromol/mg and 2.06 +/- 1.65 micronol/mg respectively for larvae and adults. The activity of glucoamylase was nearly the same for adults and larvae (about 0.20 micromol/mg). The trehalase activity was higher at adults (0.49 +/- 0.42 micromol/mg) than at larvae (0.18 +/- 0.12 micromol/mg). The activity of glycogen phosphorylase was much higher at larvae (3.58 +/- 1.49 micromol/mg) than at adults parasite (0.10 +/- 0.02 micromol/mg). The trehalose phosphorylase was present in both stages of parasite, but its activity was low. The content of glycogen and glucose was two-times higher in the adults' body than in larvae.
