The results of breeding the seaside scallop in a bottom aviary combining bottom and suspended methods of cultivation

Abstract

The cultivation of bivalves is currently one of the most promising areas of mariculture worldwide. The article discusses the advantages and disadvantages of traditional methods of cultivating scallop seaside, where the suspended method is considered more promising than the bottom. The specific productivity of cage cultivation is calculated, in which a little more than 10 ha (2.5-3.0 t/ha) is required to obtain 25-30 tons of marketable products. With the bottom method, 4-6 sites of 1 ha (2.5-5.0 t/ha) will be needed for growing 10-30 tons. The latter value even exceeds the indicators of cage cultivation, although it has always been considered as more reliable and productive. In order to minimize or avoid some of the disadvantages of traditional breeding methods, a new method of growing scallops was applied at the mariculture site in Kozmina Bay: in an aviary. The essence of the method is that before the release of the yearlings, the site is fenced with a fence from Delhi, which protects the mollusks from many predators and prevents the scallops from moving outside the site.
