| Abstract: | The experiment was done in a 5. 6square meter--cement pool. We put 41200 young fish in this pool,and after a period of time,We get more than 28564 young fish, the weight of each one is 3. 2g. The total weight is 91. 41kg. The sarvival rate is 69. 33%. In one cable meter,the density of the young fish is 7912. 5;the total weight is 25. 32kg;the feed coefficient is 1. 28;the feed efficiency is 81. 62 %. This paper describes the variaties of the technical datum of rearing salmon at high demsity. |
