Is growth inhibition in redclaw crayfish cfterax quadricarinatus regulated by chemical cdmrnunkation?

Abstract

Due to nigh consumer demand for freshwater crustaceans, rearing technology is evolving towards: intensive aojuaculture High stocking densities in such cultures result in close prgxirnity gl individuals In H trialj ive studied chemical communication and growth inhibition in order to clarify whether large males inhibit the growth of fuvenlles in Redclaw crayfish (Cfterax quadritarinatus). No growth inhibition was observed ir (uvenlles grown In the rearing water ol adults. The experimental design can be-modified to test behavioural and visual cues that may also interfere with juvenile growth.
