Abstract
Stimulation of ovarian growth was accomplished by administration of leucine -enkephalin in the fresh water field crab Oziotelphusa senex senex. The ova rian index was significantly increased in the crab after leucine-enkephalin injection, but the oocyte diameters were not significantly altered, indica ting that leucine-enkephalin stimulated more oocytes to mature. In contrast , injection of methionine-enkephalin significantly decreased the ovarian in dex and oocyte diameters.
