Abstract: The main objective of the present work is to check the applicability of a new technique for suspended fish farms and investigate the technique?s behavior under static loadings. The proposed system consists of a set of fish bags hanging from a net of pre-stressed convex cable beams hanging from guyed tower at ends. The static analysis involved in the study was carried out using a FORTRAN-coded-program based on the minimizing the Total potential energy (TPE) using the conjugate gradient (CG) technique taking into considerations the geometric nonlinearity of the structure. Many parameters were studied to investigate the structural response of the system, for instance, the net span, the cable beams stiffness, net curvature and the supporting boundary stiffness. Results show that the system may be an efficient and well-suited alternative for large-span fish farms over typical solutions.
