Electrophoretic expression of 20 enzymes coded by a minimum of 30 gene loci is reported for sea lamprey. ADA, ADH. AGP, AAT, CPK, G6PDH, GAPDH, LDH. MDH, PEP, 6PCD, PGI, PGK, PGM, PK, PMI, and SDH yielded gel resolution satisfactory for use in future population studies. Six loci, AGP, !LZDH-1, PGI-I, PGI-2, PGi%f-l, and PlMI were polymorphic. Enzyme expresion did not vary between life stages (ammocoete vs. adult) or collection method (fresh frozen vs. TFM killed). Statistically significant genetic differences occurred between lamprey fronm Lake Superior, Oneida Lake, Lake Champlain, and Bay of Fundy drainages at one or more of the polymorphic loci.
