Project ID



The mechanism for attaching fish farming nets to floating cages in the current inshore farming environment has been identified as a weak point of the structures in a high energy, offshore farming environment. This project will develop a new, robust methodology, and a marketable product for the CRC.

It will focus on the development of a collar tie replacement, undertaken alongside the collection of sensor data as it is expected that these attachment points will be identified as a weak link in existing systems. A prototype collar tie will be developed to eliminate issues with chafing and wear.

This prototype will be field-tested and refined to develop a commercially viable product ready for manufacture.

Provisional Patent & Prototype Installation

A provisional patent was granted late 2021 followed by installation of the 2nd phase optimised prototype by Tassal in offshore fish pens.
