Environmental Monitoring Around an Offshore Fish Farm with Copper Alloy Mesh Pens in the Northern Aegean Sea

Environmental Monitoring Around an Offshore Fish Farm with Copper Alloy Mesh Pens in the Northern Aegean Sea

April 10, 2017

In the present study, environmental monitoring was undertaken around an offshore fish farm with copper alloy mesh pens located in the Northern Aegean Sea. From the water velocity results obtained at the farm site, located in the Strait of Canakkale (formerly the Dardanelles) it was recorded that the horizontal water velocity reached 36cms-1 at select times. The average water velocity[...]

Engineering procedures for design and analysis of submersible fishcages with copper netting for exposed marine environment

Engineering procedures for design and analysis of submersible fishcages with copper netting for exposed marine environment

November 30, 2015

Novel design and analysis procedures are needed for engineering of the offshore fish farms utilizing copper alloy netting. Existing technologies developed for fish cages with polymer nets are not directly transferrable to the fish cages with copper netting. In particular, the structural integrity of fishcage/mooring systems, and initial high costs of fish cages with copper netting are two major concerns[...]

EFFECT OF THE BENDING STIFFNESS ON THE VOLUMETRIC STABILITY OF FISH CAGES WITH COPPER ALLOY NETTING

EFFECT OF THE BENDING STIFFNESS ON THE VOLUMETRIC STABILITY OF FISH CAGES WITH COPPER ALLOY NETTING

August 5, 2013

It has been well established that aquaculture will supply an increasing share of the world’s seafood demand in the future. Most finfish are raised in marine fish cages consisting of a floating superstructure, polymer net chamber and a sinker weight(s). These systems are susceptible to large deformations, which can lead to reduction of the cage’s volume and severely impact the[...]
