Chloride ion regulation in an eyestalk-ablated Prawn Penaeus indicus H. Milne Edwards

Abstract

The removal of ihje \ eyestalks caused a substantial increase in the haemolymph- cihloride level in batches of prawns, Penaeus indicus, kept in laboratory and, when the eyestalk exitract was injected into them, the chloride level decreased again and reverted back | tp normal. The findings are deemed as a pointer to the possible role of eyestalk endocrines in ionic regulation.
