| 摘要: |
| 本研究探讨了在封闭循环水养殖模式下大西洋鲑（Salmo salar）的生长发育模式，对封闭循环水系统养殖的大西洋鲑重要生长数量性状进行生物学测量，并跟踪性腺发育状况。本研究自2012年1月通过封闭循环水系统进行大西洋鲑养殖，经过周年养殖，体质量平均达到1194.42 g，体长平均达到417.00 mm，体高平均达到100.58 mm，体宽平均达到53.52 mm，少数个体在养殖10个月后性腺发育较快，性腺质量达到9.76 g，性腺指数达到1.31%。本研究的研究结果为建立大西洋鲑标准化循环水养殖系统积累资料。 |

| Abstract: |
| During Salmo salar aquatic culture, the gonad development speed was quicker than wild, and lack of basic information. In this study, the biological measurements of important growth traits of Atlantic salmon cultured in recirculating water systems were tested, including an examination of its gonadal development, growth, and development patterns in a closed-loop aquaculture model. The salmons were cultured in a recirculating water system in January 2012, water temperature:12-15℃, dissolved oxygen:8 L/mg-12 L/mg, ammonia nitrogen <0.5 L/mg, density:8 kg/m3-15 kg/m3, feeding rate:1%-2%, feeding times:3-6 times a day, daily addition of new water:20%, cycle range:15-18 times a day. After one year of culture, the average weight reached 1 194.42 grams (g), body length averaged 417 millimeters (mm), body height averaged 100.58 mm, and body width averaged 53.52 mm. After 10 months, for a few salmons, the gonads developed rapidly:gonad weight reached 9.76 g, and the gonad index reached 1.31%. These results provided useful information for the establishment of a standardized aquaculture system for Atlantic salmon. |
