ACTION OF BOTTOM SOIL ON PENAEID SHRIMP CULTURE

The present paper is based on the results of experiments on the adsorption of sulfide of bottom soil, which were carried out in 1979-1981, and gives special emphasis on the problem of the occurrence of the harm caused by hydrogen sulfide (H2S) to the shrimps cultured in the high-production earthen pond. The scientific basis of prevention and control of the harm caused by hydrogen sulfide occurring in the pond and a simple effective measure for high, stable production of penaeid shrimp culture are proposed accordingly.     

底质在对虾养殖中作用的研究

近年来,我国对虾养殖进展较快,但就目前养虾池的结构来看,一般都是靠潮汐换水,一时尚难完全实现流水养虾.因此,在高密度放养和大量投饵的条件下,养殖的中期末,容易出现缺氧浮头现象,严重时可因大量死亡而造成欠产.如1977年山东即墨东百里大队和1979年文登小观的高产实验池,就先后出现过这种紧急情况而提前出池.
