Escapes of fishes from Norwegian sea-cage aquaculture: causes, consequences and prevention.
TL;DR: To pre- vent escapes of juvenile and adult fish as sea-cage aquaculture industries develop, it is recommended that policy-makers implement a 5 component strategy.

Structural analysis of aquaculture net cages in current
TL;DR: A method for structural analysis of aquaculture net cages has been developed and verified for a netting solidity of 0.23, water current velocities from 0.1 to 0.5 m/s and relatively large deformations by comparing the numerical results to tests in a flume tank.

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.

Experimental investigation of wave forces on net structures
TL;DR: In this paper, laboratory measurements of forces on three different net panels exposed to five different regular wave cases are also compared with simulations using three different load numerical models, and the results of laboratory measurements also need to be validated using the results from laboratory measurements.
