THE INFLUENCE OF ECOLOGICAL FACTORS ON THE PRODUCTIVITY OF POND BIOCENOSE
Keywords:
biocenosis, intensive method, phytoplankton, biomass, zooplankton, pond water, ecological factorAbstract
Annotation: In this article, the species composition of the pond biocenosis and the ecological factors affecting their productivity were studied in the fishery farm belonging to "Ziya-Nemat Rivoji" LLC, Kuva District, Fergana Region. The productivity of carp and white carp, which are cultivated in the pond biocenosis, were analyzed in the autumn and spring seasons. According to the results of observation, the maximum period of development of fish fry, i.e. intensive growth, was observed in June, July and August. The development of pond fish is influenced by factors such as types of algae, physical properties of water, chemical composition, temperature, water clarity, amount of oxygen dissolved in water, and nutrition. Improvement of hydrobiological and hydrochemical conditions, enrichment of fish feed resources are important factors in increasing the productivity of pond biocenosis.
