Percentages of male averaged 75% in hormone-treated fish and 95% in YY male group over the sampling periods and at final harvest. The effect of sex on weight and length was statistically significant (P less than 0.001). The model used to analyse weight and length included experimental group and sex in each culture period as the fixed effects, and replicate cages as the random effect. Over the culture period of 141 days, there were no statistical differences (P>0.05) in body weight and length between mixed sex, hormonally treated and progeny of YY males. There were also no significant differences in level of variability in harvest weight between three groups of fish when the data were classified into five categories (= less than100, 100 to less than150, 150 to less than200, 200 to less than250 and ≥250 g). It is concluded that monosex culture of all male tilapia would be of no advantage over mixed sex culture for the GIFT strain under conditions of cages suspended in earthen ponds.]]> Tue 16 Oct 2018 12:17:20 AEST ]]> Turning Blokes into Sheilas: how will it help sustain the aquaculture industry of lobsters? http://research.usc.edu.au/vital/access/manager/Repository/usc:10498 Tue 16 Oct 2018 11:47:26 AEST ]]> An investigation of sexual reproduction and development in the giant tiger prawn, Penaeus monodon http://research.usc.edu.au/vital/access/manager/Repository/usc:29260 Mon 05 Aug 2019 13:02:43 AEST ]]>
