摘要/Abstract

摘要： 1997年5～9月于山东海阳市黄海集团公司养虾场,用5个实验围隔研究了对虾综合养殖生态系底泥细菌的数量动态.结果表明,底泥细菌数量波动在4.10×10⁸～12.36×10⁸cells·g^-1之间,平均为8.09×10⁸±2.17×10⁸cells·g^-1.随着养殖时间的推移,底泥细菌数量逐渐增加.底泥细菌数量最大值出现在表层1cm之内,2～3cm以下泥层,细菌数量明显减小.

关键词: 对虾综合养殖, 实验围隔, 底泥细菌, 数量动态

Abstract: The numerical dynamics of sediment bacteria was studied from May to September 1997, in the Shrimp Farm of Huanghai Fisheries Group Corporation with five experimental enclosures. It shows that the numbers of sediment bacteria ranged from 4.10×10⁸ to 12.36×10⁸ cells·g^-1,averaged 8.09×10⁸±2.17×10⁸ cells·g^-1,and increased gradually with increasing cultural time.The maximum was in 0～1cm layer,and decreased obviously bellow 2～3cm layer.

Key words: Shrimp polyculture, Experimental enclosure, Sediment bacteria, Numerical dynamics
