摘要

The productivity of the Aral Sea benthic assemblages in 1990 and the dynamics from 1950 to 1990 were estimated. In 1990, the marine macrobenthos was characterized by a high abundance of benthic organisms and high productivity of the benthic assemblages. In the coastal zone of the Small Aral Sea, the average biomass was found to be 2.4 times those in Large Aral Sea and the destruction, production, and ratin were 3 times greater than those in the Large Aral Sea. Over the last 40 years, the average values of abundance, biomass, and production of the benthic organisms of the Aral Sea have increased 4-9 times and, despite a more than twofold reduction in the area,the overall stock of zoobenthos grew almost fivefold. The total macrozoobenthos production increased approximately 2.3 times. The Small Aral Sea, which in 1990 was characterized by a high productivity of benthic communities and relatively stabile hydrological regime, has good prospects for fishery development.
