Abstract

Manual sexing of redclaw crayfish Cherar quadricurinatus was undertaken to evaluate the feasibility of monosex culture and to establish growth and yield characteristics of single sex populations. Although the all-male population exhibited greater mean weight after 10 mo of growout, all-female and mixed sex populations achieved greater total yields due to significant juvenile recruitment. Commercial cultivation of all-male populations would be advantageous as in-pond reproduction is greatly abated, growth is superior and marketable yield is higher. Apparent sexual lability of juveniles combined with the laborious nature of manual sexing may render manual sexing unsuitable for commercial applications.
