Journal ArticleDOI
Hydrodynamic interactions on net panel and aquaculture fish cages: A review
TL;DR: The present status of flow hydrodynamics within and around sea-cages is reviewed, providing a framework for understanding the spatial and temporal variability of key environmental parameters within and outside sea-Cages.
Journal ArticleDOI
Experimental investigation of forces and geometry of a net cage in uniform flow
Pål Lader,Birger Enerhaug +1 more
TL;DR: In this article, a scale model of a flexible circular net with different weights attached to the bottom was tested in a flume tank and global forces and net deformation were measured for different steady current velocities.
Journal ArticleDOI
Review of cage and containment tank designs for offshore fish farming
TL;DR: The definition of offshore for fish farming is defined based on unified viewpoint and different types of cage designs are compared with the view to guide feasibility of offshore fish farming to address challenges faced by going offshore.
Journal ArticleDOI
Current induced net deformations in full-scale sea-cages for Atlantic salmon (Salmo salar)
TL;DR: In this article, the authors measured acoustic current meters at two full-scale commercial Atlantic salmon farms (Varaldsoy, Norway, Hestur, Faroe Islands) and found that the most critical current/deformation combination was 0.13 −m −1 and an estimated 20% cage volume reduction, while current speeds of 0.35 −m−s −1 caused a corresponding 40% volume reduction.
Journal ArticleDOI
Dynamic properties of a flexible net sheet in waves and current—A numerical approach
Pål Lader,Arne Fredheim +1 more
TL;DR: In this article, the dynamic properties of a flexible net sheet exposed to waves and current were investigated by using a numerical model, where the net was modelled by dividing it into super elements, and the structural and hydrodynamic forces were calculated for each element.
