| 中文摘要: |
| 以吉富罗非鱼（Oreochromis，GIFT）为研究对象，探讨了鱼腥草（Houttuynia cordata Thunb.）-
罗非鱼的鱼菜精养模式、鱼腥草- 罗非鱼- 黄颡鱼（Pelteobagrus fulvidraco）的鱼菜混养模式和罗非鱼传
统精养模式等3 种养殖模式对罗非鱼生长和消化酶活性的影响。研究结果显示，在宏观水平的生长指标方
面，鱼菜精养模式下罗非鱼肝体比系数低；样本鱼体重均重和肥满度在3 种养殖模式间差异不显著。比较
消化酶活力发现，传统精养模式胃蛋白酶在多数月份显著低于鱼菜精养和鱼菜混养模式，鱼菜精养模式肝
蛋白酶活性最高，鱼菜混养模式在多数月份肠蛋白酶活性最高；7、10 月份鱼菜精养模式肝胰脏脂肪酶和肠
脂肪酶活性最高。鱼菜精养模式肠淀粉酶活性最高，肝胰脏淀粉酶在8 月份最低，9 月份显著高于传统精养
模式，其他均未达到显著性差异。鱼腥草生态浮床对水环境的改善使鱼菜精养模式下的吉富罗非鱼表现出
较高的消化能力；鱼菜混养模式下鱼的放养密度过大造成拥挤胁迫最终影响罗非鱼的生长状态。 |
| 英文摘要: |
| GIFT tilapia（ Oreochromis niloticus） was used as animal model，and three aquaculture modes，
including herba houttuyniae（ Houttuynia cordata Thunb.）-tilapia intensive aquaponics mode（ IAM），herba
houttuynia-tilapia-yellow catfish（ Pelteobagrus fulvidraco） polyculture aquaponics mode（ PAM） and conventional
intensive aquaculture mode（ CIAM），were selected to investigate the effects of aquaponics on growth and digestive
enzyme activities of GIFT tilapia. Results showed that on the level of growth performances，the hepatosomatic index
of tilapia in IAM was the lowest. However，there was no significant difference on average weight and relative fatness indices among the tilapia under three modes. For digestive enzyme activities，the stomach protease activity of tilapia
in CIAM was significantly lower than that in other two modes. While the protease activity of tilapia hepatopancreas
in IAM and protease activity of tilapia foregut in PAM were the highest，respectively，during most of experimental
months. Moreover，both in July and October，the lipase activity of tilapia hepatopancreas and foregut in IAM were the
highest. The amylase activity of tilapia foregut in IAM was the highest. The lowest amylase activity of hepatopancreas
was observed in IAM in August，and the amylase activity of hepatopancreas in IAM was significantly higher than that
in CIAM in September，while the other groups showed no significant difference. Herba houttuynia ecological floating
flats can improve the water quality for aquacultural environment，thus，intensive aquaponics mode showed higher
digestive ability. The stocking density of fish in polyculture aquaponics mode was too intensive，which led to the
crowding stress，damaged the growth and health of tilapia. |
