| 摘 要： | 为评价异育银鲫‘中科5号’稻田养殖效果,在武夷山稻花鱼养殖基地开展异育银鲫‘中科5号’稻田投饵和不投饵养殖方式的试验,测定养殖鱼类的生长性能及产量,分析存活率、特定生长率等生产指标和产出投入比、养殖成本利润等养殖效益。结果显示,经过62天稻田养殖,异育银鲫‘中科5号’稻田投饵养殖模式的产量、成活率、增重率和体质量特定生长率分别是稻田不投饵养殖模式的2.17、1.47、1.98、1.60倍,平均规格和肥满系数显著高于稻田不投饵养殖模式(P＜0.05)。在本试验条件下,稻田投饵养殖模式平均单位利润达到9817.50元/hm2稻田,是不投饵养殖模式的2.23倍。因此,稻田投饵方式养殖异育银鲫‘中科5号’较不投饵养殖方式收入更高,但还应进一步提高饲料利用效率、降低劳动力成本,以提高养殖经济效益。

| 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. |
