| Summary: | The technology of collection of Patinopecten yessoensis larvae on mesh collectors, designed in Japan, requires transplantation of juveniles into cages. However, this transplantation is labor-intensive and dangerous to the species being cultivated. In cultivation ofthe oysterCrassostrea gigas, a lot of time is spent to increase the distance between scallop valves after larval settlement on them and to remove excess juveniles from them. at the same time, the use of the realized niche, instead of the fundamental one, in selecting the area and the depth to install the collectors and improving their design, provides an opportunity to grow these bivalves without transplanting them to other constructions. This not only facilitates the cultivation process, but also increases the growth rate and the survival rate of the species cultivated, because being exposed to air and various technological operations pose a strong stress to it.
