Sažetak
The δ−aminolevulinic acid dehydratase (ALA-D) activity was examined in two groups of carp (Cyprinus carpio L.) exposed to sublethal lead concentrations (1.3 and 2.6 ppm) for 60 days. There was no statistically significant change in ALA-D activity at one-month lead exposure. After two months, ALA-D activity was decreased in both experimental groups of fish compared with the control group. The decrease in ALA-D activity reached statistical significance (P<0.05) in the group of fish administered 2.6 ppm lead in feed. ALA-D is probably the best indicator of fish exposure to lead. Feed is an important source of ground-fish lead contamination that can compromise fish health and reduce their productivity.
