| 中文摘要: |
| 通过分析定期施用发酵猪粪和不施肥两种养殖模式麦瑞加拉鲮鱼（Cirrhina mrigola）的生长、
水质及胃肠道饵料生物结构，探索发酵粪肥在鲮鱼高密度养殖中的应用价值。结果表明，适量的发酵粪肥
投入池塘可以促进鲮鱼生长，肠道充塞度指标增加；投喂发酵粪肥可有效降低池塘水体氨态氮浓度，表明
粪肥可以作为一种有机碳源补充，调节池塘水体碳氮平衡，促进异养细菌繁殖，但投喂粪肥池塘的悬浮固
体物总量显著升高；投入粪肥池塘浮游动物枝角类数量显著性多于未投入粪肥的池塘，浮游植物藻类的数
量也显著增加；投喂粪肥池塘的鲮鱼肠道内容物含量较未投喂粪肥的池塘呈现显著增加，鲮鱼肠道轮虫和
原生动物数量在投入粪肥的池塘显著高于未投粪肥的池塘。 |
| 英文摘要: |
| Mud carp（Cirrhina mrigola）is one of major economic fishes in south of China because of its
high commercial value for mandarin fish（Siniperca chuatsi）farming. In this study，we investigated the growth，
water quality and biological structures of gastrointestinal food of mud carp two farming modes，to consider the value
of manure fermentation in high-density culture of mud carp. The results showed that moderate manure fermentation
can promote the growth of fish and make intestinal stuffed index increased. Feeding fermented manure can effectively
reduce the water ammonia nitrogen concentration，suggesting that manure can be used as an organic carbon source
regulating carbon/nitrogen balance and promoting heterotrophic bacteria growth. However，the total amount of
suspended solids in pond increased significantly. The zooplankton Cladocera amount in treatment pond was significant higher than that in control pond. The number of phytoplankton algae also increased significantly. In manure pond，
fish's intestinal contents showed a significant increase，fish intestinal protozoa and rotifers were significantly higher
than that in control pond. |
