The bester becomes the popular species of the farming fish because its growth is quick, the adaptdbility is wide, the anti-disease dint is strong, has proceeding farming in national locality,but most is farming in fresh water. The bester is miscellaneous to hand over the interspecific or generic, and there are three kinds among them have most farming value and have expanded farming in our country, they are bectep、BBC and pactp, but the one most has farming potential is bectep. The farming methods of bester are intensive turning following water farming ,pool farming and cage farming ,also can be divided into the fresh and the salt water farming. It is the nessary step to tame the bester in salt water for sea farming. Zhejiang Ocean University graduate school took the experiment of the bester salt water taming in the Shengsi farming factory in 2002 july. The taming turn to sea water through 36 days with 98% survive rate achieved success, evening the road spreading to sea farming. And then from 2003 november a experiment of the bester farming in the offshore cage was taken in the Shengsi Lvhua offshore cage base for four months. With 85% survive rate and 453.0g increment of weight achieves success. And so on, the process of the bester sea farming had completed all, can enter the stage of farming in scale. 目录 中英文摘要…………………………
