The proposed invention relates to the field of ecology and aquaculture, and in particular to artificial reefs, which stimulates an increase bio-productivity of bottom waters, and can be used to create the underwater habitat and spawning areas, recovery of underwater ecological communities, increasing their productivity, biodiversity conservation of the underwater world, a natural biological treatment water, creating places with guaranteed coolest for sea fishing, aquaculture and mariculture, increasing commercial fish stocks and other seafood, fisheries reclamation, compensation measures to address the environmental damage, the creation of new underwater attractions for the development of diving and tourism, advertising on the seabed, protecting bottom areas from erosion as one of the elements of the coastal protection, etc. The inventive structural element to create an artificial reef formed in a rod shape and having a central longitudinal portion, at least partially coated with a layer of concrete, wherein the central longitudinal portion is made of fiberglass or basalt. Thus, the claimed utility model is a structural element of artificial reef construction which achieves the technical result consisting in increasing its service life, reducing weight, providing the possibility of installing a soft and muddy bottoms liquid, simplifying installation and reducing cost.Предлагаемая полезная модель относится к области экологии и аквакультуры, в частности к искусственным рифам, стимулирующим повышение биопродуктивности площади дна акватории, и может быть использована для создания подводных местообитаний и нерестилищ, восстановления подводных биоценозов, повышения их продуктивности, сохранения биоразнообразия подводного мира, естественной биологической очистки воды, создания мест с гарантированным клевом для морской рыбалки, аквакультуры и марикультуры, увеличения промысловых запасов рыбы и других морепродуктов, рыбохозяйственной мелиорации, компенсационных мероприятий п
