ARTIFICIAL REEF Russian patent published in 2010 - IPC A01K61/00 

FIELD: agriculture.

SUBSTANCE: invention relates to fishery immediately dealing with design of artificial reefs serving to stimulate bioproductivity of benthal biocenoses; additionally it is to utilised in construction of hydraulic engineering structures. The artificial reef is assembled of structural elements that have a recess in the central part of their upper bases; connected to each other, the elements form shelters for hydrocoles. The innovation consists in the structural element being shaped as an isosceles trapezoid with the wall section increasing by a factor of 1.5-2.0 towards the lower base; the element has two additional recesses arranged in the upper and the lower bases different sides of the centre with the recess height being equal to 1/2 of the element height, the width exceeding the lower base thickness by 10-15 cm; the elements are connected by way of the lower recess of one element being inserted in the upper recess of another one.

EFFECT: improvement of the reef stability, reliability and strength as well as reduction of its assembly process labour intensity.
