The hemolymph of Chasmagnathus granulata Dana, 1851 (Decapoda-Grapsidae) as a target tissue of the crustacean hyperglycemic hormone.
The effect of crustacean hyperglycemic hormone (CHH) was investigated on the hemolymph of Chasmagnathus granulata, a meso-supralittoral crab from southern Brazil. Serum glucose increased significantly (P less than 0.05) after incubation of total hemolymph in the presence of the eyestalk extract of a member of the same species. Also, glucose uptake from blood serum, not affected by eyestalk extract (P greater than 0.05), was observed after incubation of total hemolymph in the presence of glucose. The results suggest that the hemolymph may be a target tissue of CHH and that this hormone may act by mobilizing carbohydrate reserves possibly from hematocytes.
