A Brief History of Nets Tasmania

The first Australian Aquaculture net making company – a company built on an enthusiasm for the art of net making, and determination to turn out the best product possible for its fish farm customers.

Inception of commercial scale farming Salmonids

Inception of commercial scale farming Salmonids in Tasmania Commencement of assembly of fish farm nets to meet the needs of many independent small farms licensed to farm in sea water, Saltas joins with partners from Norway under State Government auspices to provide technical & scientific expertise to the developing Aquaculture industry. NETS use industrial sewing machines for joining netting seams. Staff travel internationally to gain understanding of netting applications in all major fish farming areas worldwide. Standard size nets of 40M & 80M circ.

Machine seaming discontinued in favour of traditional hand skills

Machine seaming discontinued in favour of traditional hand skills of net making staff. Circular 120m circ. HDPE fish cages become the standard design for Australia. Innovations in predator nets as separate systems surrounding fish enclosure nets. Overseas experts brought to Tasmania to help in the fight to control seal attacks and damage on fish farms. NETS commences producing wire predator exclusion nets. Shooting of seals by farmers in Tasmania is prohibited by law.

First nets sent to Barramundi farms in Queensland and Lake Argyle

First nets sent to Barramundi farms in Queensland and Lake Argyle. Prawn farms commencing and being supplied with exclusion protection and harvest nets. Small scale fish salmon farmers grouping into larger public companies.

Farming of Tuna on Eyre Peninsula

Farming of Tuna on Eyre Peninsula requires development of sea towing cages and static culture cages specifically for South Australian conditions. Some farms start growing stock salmon in rectangular modular systems similar to those in Norway and Scotland. NETS responds with an innovative type of system farm nets.

Boom time for Orange Roughy fishing in Tasmanian waters, this provides opportunities for expansion of local net making and brings the presence of New Zealand net companies into Tasmania. Netting based system for Abalone farming developed.

All nets up to this time are made up from Nylon knotless netting the size of twines to give seal attack resistance are now beyond manufacturing limits, attempts to use alternatives, super knots to restrict seal rips and Dyneema to improve strength of netting.

First trials of Co Polymer knotless netting production

First trials of Co Polymer knotless netting production leads onto the initiation of Super 20 Mono netting. Dramatic improvements in reducing seal attack by NETS tensioned designs.
