Accumulation of Microelements in Organs and Tissues of Fishes Differing in Feeding Specialization under Conditions of Cultivation in Fishponds with Heated Water

RESUMO

Accumulation of manganese, zinc, copper, and iron in organs and tissues of three fish species − Cyprinus carpio, Ctenopharyngodon idella, and Salmo gaird-neri − was studied in the course of their cultivation in fishponds. Fishes received food with different proportions of ingredients of plant and animal origin. Fishes with different feeding specialization proved to differ in the level and dynamics of metal accumulation and the ratio of microelements in organs and tissues. Significant changes of metal contents in tissues during the growing season (from June to November) are explained by variation in the intensity of metabolic processes, biological demand for microelements performing different physiological functions, provision of fish organism with these microelements, and their metabolic expenditures.
