FIELD: agriculture, in particular, poultry or fish farming. SUBSTANCE: method involves exposing specimens to dosed suppressing action of, for instance, carbon dioxide gas, with gas dosage being determined by its effect: for example, when specimens are on their sides - these are males and weakened females; upon termination of suppressing action, stimulating specimens to get out into light and air. Females are normally the first to do it. Later males recover. Method may be used to separate chickens by sex and in fishery to change male-female ratio of young salmon and sturgeon fishes. EFFECT: increased efficiency, wider operational capabilities and simplified method.

Способ разделения особей по полу, заключающийся в том, что особей подвергают дозированному угнетающему воздействию, например, углекислого газа, а дозу определяют по ее воздействию, например, на боку половина особей, которые есть самцы и ослабленные самки. После прекращения угнетающего воздействия, особей стимулируют, например, перемещаться на свет и свежий воздух, что самки и делают. Через некоторое время и самцы приходят в себя. Способ может быть использован в птицеводстве: для разделения цыплят по полу и в рыбоводстве для изменения соотношения самцов и самок у мальков лососевых и осетровых рыб.The method of dividing individuals by sex, namely, that individuals are subjected to a dosed inhibitory effect, for example, carbon dioxide, and the dose is determined by its effect, for example, on the side, half of the individuals, which are males and weakened females. After the cessation of the inhibitory effect, individuals are stimulated, for example, to move to light and fresh air, which females do. After some time, the males come to their senses. The method can be used in poultry: to separate chickens by sex and in fish farming to change the ratio of males and females in fry of salmon and sturgeon.
