چکیده انگلیسی
A comparison with the eucarid crustaceans Pandalus montagui, Pagurus bernhardus, Cancer pagurus and Euphausia superba showed a similar high level of total proteinase activity in all species. Trypsin, however, varied significantly between species showing lowest activities in Caridea and the highest activity in E. superba. E 64 suppressed total proteinase activity by more than 70% in Crangon species but not in C. pagurus and E. superba. In contrast, the serine proteinase inhibitor AEBSF had only little effect in Caridea but was most effective in P. bernhardus, C. pagurus and E. superba. The results may indicate different traits of food utilization strategies in some eucarid crustaceans. Caridea may express predominantly cysteine proteinase, while in Anomura, Brachyura and Euphausiacea, serine proteinases may prevail.
