Abstract:

To evaluate the efficacy of allogynogenetic gibel carp ‘CAS V’ in paddy field cultivation, the experiments with feeding and unfeeding cultivation mode were carried out in Wuyishan. The growth performance and production of fish were measured, the survival rate, specific growth rate and production index and input-output ratio were analyzed. The results showed that, after 62 days’ paddy field cultivation, the production, survival rate, weight gain rate and specific growth rate of allogynogenetic gibel carp ‘CAS V’ in the feeding mode were 2.17, 1.47, 1.98 and 1.60 times of those of the unfeeding mode respectively, and the average size and condition factor were significantly higher than those of unfeeding mode (P<0.05). Under the experimental conditions, the unit profit of the feeding mode of paddy field cultivation was 9817.50 yuan/hm2, which was 2.23 times of that of the unfeeding mode. Therefore, the income of allogynogenetic gibel carp ‘CAS V’ of feeding mode is higher than that of unfeeding mode, but more efforts should be done to improve the efficiency of feed utilization and reduce labor cost to raise the economic benefits.

Key words: allogynogenetic gibel carp ‘CAS V’, paddy field cultivation, cultivation mode, growth performance, economic benefits
