In the netting industry, FISA, official name Fibras Industriales SA, is one of the world’s leading fishing net and cage manufactures with over 70 years’ experience.
They are a vertically integrated company that starts their process with the extrusion of polypropylene (PP) or polyethylene (PE) followed by twisting and weaving for the twisted knotted netting, braided knotted netting and twisted knotless shogun netting or knitting for the raschel knotless netting.
After finishing their products with pre-shrinking, heat setting and applying the most adequate bonding, FISA transfer the netting and ropes to their 28,000m2 specialised net loft where the process of rigging nets for purse seiners or cages, for all species of farming, will take place. In FISA’s previous article, from July 2017, they covered the importance of abrasion and UV resistance for fish cages and specified in detail the different benefits of various type of products such as FISA’s Polymax and Polytar ropes.
FISA emphasised the importance of accelerated abrasion and UV tests, thus reflecting the behaviour of the material over time and the effect these forces have over the products. This effect can possibly lead to a situation where a product with a higher initial breaking strength turns out to have a very low UV and/or abrasion resistance and after a short period of time (12-18 months).
On the other hand, what seemed like a lower resistance product retains more of its characteristics and turns into a longer life product. Following, there will be a short description of the differences and potential advantages or disadvantages of the different raw materials available for manufacturing the netting used in aquaculture fish cages.
