Criteria for selection and design of cage structures adapted to the environment

The use of cage structures due to the advantages of increasing production capacity with the size of the sea, the ability to self-purify in marine environments, water ventilation, lack of oxygenation, reduction of depreciation costs, repair and maintenance and the use of natural environment has provided good conditions for aquaculture. The performance and production of cage-based structures depend on a variety of factors, such as the type of design, size and material used in structures, environmental diversity including relatively protected and closed locations, open or exposed areas, and types The cage includes floating and immersed cages. Therefore, the necessity of designing the structure in accordance with the environment is of special importance and the present article, in line with the above objectives, examines the considerations of choosing and designing cage structures. The goal is to determine the parameters such as effective wave height, wind velocity, wave motion and wave pattern, cage, in accordance with the climatic conditions of each region. It is also possible to predict the amount of force on the structure caused by the abovementioned factors. Therefore, by identifying undesirable consequences and choosing the type and method of deployment of the cage structure in accordance with the region conditions, destructive effects can be minimized and a significant improvement in the performance of cage structures. The results of the research showed that the force generated by the flow of waves in comparison to other factors predominates and plays a decisive role in the design of the cage
