| 摘要: |
| 本文根据大银鱼在道观河水库移植后的生长资料，计算出其生长指标，相对生长率和平均丰满度，对大银鱼在道观河水库的生长规律进行了分析，得出其体长体重关系为W＝1．2120×10-6L3．1820和VonBertalanffy生长方程的各项参数值：L∞＝193．03mm，W∞＝22．72g，K＝0．3328，由此得出大银鱼在该地区水域能移植驯化的科学依据．并据此为道现河水库大银鱼的最佳捕捞时间提出了初步的意见。 |

| Abstract: |
| Based on the growth information for Protosalanx hyalocranius transplanting in Daoguanhe Reservoir, Hubei Province,the growth index,the growth rate and the other indexes were calculated. The regrssion relationship of the body length and the body weight were gained： W=1. 2120X10-6L3.1820 and Von Bertalaffy growth equation： Lt = 193. 03[ 1-e-0.3050(1-3328)] Wt = 22. 72[l-e-0.3050(l-0.3328)]3. This paper stated in detail the growth character of Protosalanx hyalocranius transplanted in Daoguanhe Reservoir, divided the growth into four stages and compared it with those in other reservoirs.It was concluded that Protosalanx hyalocranius had both biological effect and production benefit as well in the waters of Hubei Province. |
