FIELD: pisciculture.
SUBSTANCE: one should perform annual sporing the carriers with laminaria zoospores to place them on horizontal ropes of suspension sea plantations, cultivate laminaria being the collector for sea urchin larvae sedimentation followed by their sedimentation onto the bottom under plantation and at achieving armor's diameter of 40-45 mm in greater part of sea urchin's colony, sea urchin's feeding due to 2-fold deepening the carriers with cultivated laminaria into sea urchin's habitat at interval of 30-50 d, at quantity being not less than 9 kg/5 sq. m during the first feeding and not less than 18 kg/5 sq. m during the second feeding followed by collecting commercial laminaria and commercial sea urchin. The innovation enables to increase population of sea urchin and improve its marketable quality.
EFFECT: higher efficiency of combined cultivation.
