Abstract:

   Method of evaluation of phytomass production of aquatic vegetation as well as other bio-resources, production of which depends on the level of vegetation development by the visually assessed characteristics of a man-made water body, namely its type, stage of succession (primary-lake, actuallylake, ultimately-lake) and the level of overgrowing is suggested. Using of presented tables and obtained evaluations of plant production also allow us to calculate the potential productivity of bio-ameliorative fish species.

Keywords: man-made water bodies, eutrophic-lake condition ,eutrophic-swamp condition, production of higher aquatic vegetation, natural fish productivity.
