Abstract:

The purposes are to enrich the variety of comprehensive rice-fishery cultivation, make full use of paddy resources, expand market supply and provide an important basis for the steady development of rice fishery comprehensive farming industry in mountainous areas. The comparative analysis on ecological comprehensive rice-fishery cultivation of Allogynogenetic gibel carp ‘CAS Ⅲ’ and Cipangopaludina cahayensis was conducted in Wuyishan City. The results showed that after 139 days of cultivation, the total yield of ‘rice+crucian carp+snail’ model reached 9937.5 kg/hm2, 7.72% higher than ‘rice+crucian carp’ model, but 7.67% lower than ‘rice+snail’ model. The total profit of ‘rice+crucian carp+snail’ was higher than that of ‘rice+crucian carp’ and ‘rice+snail’ model by 25.83% and 77.91% respectively; the comparative benefits of output-input ratio, cost profit and sales profit rate were significantly higher than those of the ‘rice+snail’ model. The ecological farming model of ‘rice+crucian carp+snail’ could effectively improve the comprehensive farming effect of paddy field, but it is also necessary to optimize the key technologies and the mixed proportion of aquatic animal stocking in order to further improve the comparative benefits of rice-fishery cultivation in paddy field.

Key words: ecological comprehensive rice-fishery cultivation, Cipangopaludina cahayensis, Allogynogenetic gibel carp ‘CAS Ⅲ’, culture effect, comprehensive benifit
