Hemolymph Ecdysone Concentration as a Function of Sexual Maturity in the Male Snow Crab ( Chionoecetes opilio )
Ecdysone concentrations in the hemolymph of juvenile and morphometrically mature male snow crab (Chionoecetes opilio) were determined by radioimmunoassay. A logarithmic transformation of the allometric relationship of the dry weight of the chelae versus the carapace width was used to identify morpho...
