Fishing Vessels as Ships of Opportunity
The IMOS Fishing Vessels as Ships of Opportunity sub-Facility works with the fishing industry to collect near real-time subsurface sea temperature measurements by installing equipment on fishing gear deployed by a network of commercial fishing vessels.
Every day, fishing vessels operate broadly across coastal, shelf and offshore waters within Australia’s Exclusive Economic Zone. Fishing Vessels as Ships of Opportunity utilises this opportunity to cost-effectively fill data gaps and increase the spatial and temporal resolution of subsurface sea temperature observations in Australia’s marine estate.


How it works
Compact, calibrated, low-cost sea temperature sensors are attached to a range of commercial fishing gear (including fish trawl nets, scallop dredges, demersal and pelagic longlines, gillnets, prawn trawl nets, traps and squid jig gear), which collect highly accurate sea temperature at depth measurements.
The sensors operate with minimal human intervention and communicate directly to a solar powered deck box, transmitting data in near real-time.
Data collection
Time, position, depth and sea temperature data are recorded when fishing gear is deployed. These data are then transferred via Bluetooth to a solar-powered deck box installed on the vessel, and forwarded to the IMOS sub-Facility for data processing. The data are then quality checked with any identifying vessel information removed, before being transferred to the IMOS Australian Ocean Data Network (AODN) in near real-time for uptake.
A report summarising the data collected on a vessel is emailed back to the participating fisher for their own information, usually within 24 hours, enabling skippers to relate their catch to temperature-at-depth information.

Why it’s important
The data strategically fill an important gap in the observing system and will assist in standardising catch rates in fisheries stock assessment models, support safe and efficient maritime operations, sustainable management of marine resources, and improve understanding of drivers of ecosystem change.
In the long term, the data will help our understanding of the changing marine environment and its impact on fish distribution and abundance, as well as provide oceanographers with quality-controlled data on an unprecedented scale for ground-truthing coastal models and to improve analysis and forecasts of oceanic conditions.
