Around 40% of the fish products consumed in the world come from aquaculture. The breeding of fish, molluscs and crustaceans is therefore essential to meet the growing demand for fish products and at the same time plays a key role in protecting the delicate balance of marine and coastal ecosystems through respectful and sustainable techniques and structures.
Here we offer an in-depth look at the wire mesh used in aquaculture and fisheries, particularly in the USA.
Wire cages for crustacean fishing in the sea and shellfish farming
Wire mesh are used in aquaculture for the construction of large rigid cages (creels), mainly for offshore crustacean fishing and mollusc farming, with widespread use in both the USA and Australia.
Pots are widely used in the Atlantic and off the coast of Alaska to catch crustaceans, particularly giant crabs. The pots are rigged with bait fish, lowered to great depths, tied by rope to a surface buoy and then retrieved after several hours.
Metal cages are also used for shellfish farming, i.e. the breeding of mussels, clams and oysters. This type of farming is completely sustainable as these animals feed on the micro-organisms in the water (by filtering it) and do not need any feed. They do, however, require a safe breeding environment to ensure that we do not take in any substances that are harmful to our health through the consumption of these molluscs.
Seaplax: the mesh for aquaculture signed by Cavatorta
Seaplax is a welded wire mesh made from high tensile steel wire, signed by Cavatorta, which is galvanized after welding and then coated with PVC using the Seaplax Process. An exclusive technology that ensures resistance to immersion in salt water and temperature changes. This mesh is ideal for the creation of lobster and crab pots, fish traps and aquaculture.
Seaplax PVC is extremely flexible, cold crack and impact resistant at low temperatures. The marine duty coating is able to withstand continuous immersion in chemical and salt water. Seaplax has superior abrasion resistance, retains its physical properties and colour during exposure to severe weather conditions and has excellent resistance to UV light.
Furthermore Cavatorta has a division dedicated to the design of special mesh that are tailored to the customer’s needs and designed according to their intended function and context of use. We have been working for years in the aquaculture sector and over time have developed solutions and technologies that can offer excellent performance in the field of fish farming.
