Abstract

Today, cage aquaculture in the open sea is a new approach and is one of the most important reasons for the success of communities in the aquaculture industry. This approach provides the basis for increasing production capacity due to the vastness of the seas and, due to the lack of need for aeration, reduces the costs of supply and maintenance and, consequently, suitable breeding conditions. In order to achieve the above goals, it is necessary to focus more on the technical aspects in order to pave the way for the development and commercialization of this technology. In this research, scientific points and findings in the design and implementation of cage structures have been presented. These tips include the basics of site selection, building materials, and finally estimating the size and number of cages.

Examining the experimental data samples, the relationship between cage net size, biomass weight, and fish weight was presented. The results also showed that with increasing the cultivated area, the number of required cages has almost linear growth, so that with 5 times the area, the number of required cages will increase by a factor of 1.2. Regarding the material of cages, the results indicate that the material of cages suitable for breeding in the Caspian Sea and Persian Gulf waters is polyethylene, but the volume of cages in the Caspian Sea is about 2.25 times larger than the waters of the Persian Gulf.
