METHOD OF FISH CULTURE IN POLYCULTURE IN POND Russian patent published in 2008 - IPC A01K61/00 

FIELD: agriculture, fishing industry.

SUBSTANCE: invention relates to fish culture, particularly to cage culture of fish and can be used for cultivating planting materials, fish for sale and for producers of different species of fish in polyculture in the pond. The method includes culturing one or several valuable species of fish in single pondage of the large pond by means of its extensional isolation or dividing from each other. The method is carried out by stocking valuable species - sturgeons, salmon, sheatfishes - in one or several additional smaller ponds placed into the main large pond that is stocked with one or several additional species of herbivorous fishes: silver carps, bigheads, grass carps or species of whitefishes, mullets depending on species and technological norms for raising of the main species. The bottom of the pond is placed on the bed, if the depth of basin is less than 5-7 m a cloth made of polymer material is layed on the bottom of the pond to collect remnants of feed-stuff and excrements of cultivated fishes.

EFFECT: transformation of feed stuff remnants and waste products of the main species into the additional fish production ensures efficient use or recourses, at the same time the organic contamination of the pond decreases, feed costs per unit of the product also decrease, fish capacity and usage efficiency of production facilities increase.
