The marine environment in the State of Qatar is increasingly impacted by illegal, abandoned, or lost fishing nets. Once nets are cast into the ocean, they are extremely difficult to locate again, particularly when they sink or become entangled in coral reefs, marine wildlife including endangered species, or critical offshore infrastructure such as oil and gas platforms, subsea pipelines, and marine cables. These ghost nets continue to cause ecosystem degradation, fish mortality, operational disruption, and rising costs for monitoring and removal.
The scale of the challenge is significant. Individual fishermen typically deploy fishing nets ranging from 2 to 3 kilometres in length, and when aggregated across the fishing community, the total length of nets operating within Qatar’s waters reaches substantial levels. Given this scale, post-loss detection alone is insufficient, and there is a need to focus more upstream on the moment nets are deployed, as well as on reducing the overall duration and impact of lost nets in the marine environment.
Current approaches rely largely on periodic field inspections and reports from Coast and Border Security, QatarEnergy, and sea-goers. These methods do not provide real-time or comprehensive visibility and are constrained by manual processes. Traditional techniques such as visible or night-light buoys have proven ineffective due to theft, damage, and the inability to locate nets once submerged, particularly at depth. Previous trials have also shown limitations arising from inaccurate location tracking caused by water currents, high manpower requirements including the need for divers, the absence of a centralized digital system, and challenges in identifying net ownership in cases of loss or violation.
The challenge therefore seeks effective, scalable solutions that reduce the environmental impact of fishing nets across their full lifecycle. Solutions will be evaluated based on their overall effectiveness in lowering harm to the marine ecosystem rather than adherence to a single technological approach.
The long-term ambition is deployment across Qatar’s full Exclusive Economic Zone. For proof-of-concept validation, solutions should demonstrate feasibility at depths of 15 to 20 metres initially, with a clear and credible pathway to operate at depths of up to 60 metres. Solutions that prove robust in the marine context may also present opportunities for extension into land-based tracking or recovery applications.
Illustrative solution directions (non-exhaustive examples)
- Net tagging and tracking: Attaching physical or digital identifiers to nets to enable location tracking, ownership identification, and detection of lost or abandoned nets once deployed.
- Retrieval-first approaches: Locating and removing lost or abandoned nets efficiently, for example using underwater drones or other autonomous underwater/surface systems to reduce time-in-water and ecosystem damage.
- Impact-limiting net design: Developing nets that degrade, deactivate, or lose fishing effectiveness over time to minimise long-term harm where tracking or retrieval is not feasible.
Note that these are just examples of solution directions. MOECC is open to consider any solution that can effectively help tackle the issue.
