Abstract

We compared the effects of prostaglandin E₂ (PGE₂) in vitro, as reflected by cAMP levels, on ovaries and testes of the giant prawn Macrobrachium rosenbergii (Decapoda, Caridea) and the redclaw crayfish Cherax quadricarinatus (Decapoda, Astacidea). These decapods differ in their reproductive physiology, representing distinct reproductive strategies. In both ovaries and testes of M. rosenbergii, PGE₂ (10 μg/ml) significantly stimulated cAMP synthesis, the reaction being augmented by IBMX. In contrast, in both ovaries and testes of C. quadricarinatus, PGE₂ had no effect on cAMP levels. In muscular tissue, which served as the control for both species, cAMP levels were unaffected by PGE₂. This comparative study suggests a case of different responses to PGE₂ in the gonads of 2 decapod species that have distinctly different reproductive biologies.
