Orange roughy is an important species in New Zealand deepwater fisheries with current annual landings of about 6500 t. The research plan for orange roughy fisheries includes a programme of acoustic surveys on aggregations of orange roughy during the winter spawning period. This includes a survey on the Mid-East Coast (ORH 2A South, 2B, and 3A) in 2016/17.
Because orange roughy lack a swim bladder and have a low target strength relative to other deepwater species, acoustic survey biomass estimates were historically restricted to aggregations of fish where the species identification of the mark is known to be almost 100% orange roughy. In more recent years, a net-attached Acoustic Optical System (AOS) has been used successfully to survey orange roughy in several areas including the Chatham Rise and Challenger Plateau. The advantage of this system is that the multi-frequency and optical components of the system can be used to significantly improve species identification in orange roughy aggregations.
MPI is looking for credible providers with a proven track record of delivery of similar surveys, including the ability to successfully deploy and use a multi-frequency Acoustic Optical System. Any survey design must be consistent with that recently approved by MPI’s Deepwater Fisheries Assessment Working Group and demonstrate value for money.
This is an opportunity to contribute to the monitoring and management of one of New Zealand’s iconic deepwater fisheries and to demonstrate the benefits of new acoustic technologies.
