摘要

This paper focuses on the fish ponds phytoplankton structure and its evolution during a vegetative season in three Romanian cyprinids farms which grow out table fish in poly-culture. The technical differences among the studied fish farms are represented by the source of ponds water supply and the size of the ponds. To establish the structure and the dynamics of the phytoplankton, there were collected two sets of biological samples, at the beginning and at the end of vegetative season, from 6 sampling stations in each fish pond. The vegetal plankton was analysed from a qualitative (the number of individuals and species) and quantitative (the relative taxa density and the numerical abundance) points of view. The phytoplankton was representative in all sampling stations during the entire vegetative season. The number of taxa and exemplars from the same algal species identified in the structure of phytoplankton emphasises a small trophic level of the pond, which is cumulated with a reduced phytoplankton biodiversity during the studied period.
