Toolkit: Derelict Fishing Gear Retrieval, Implementing your project, Monitoring DFG

This activity only refers to the monitoring of the collected DFG, with the objective of learning more about the problem of DFG in the intervention area. It does not refer to monitoring of the overall project implementation, which is covered under Project monitoring and evaluation.

To allow monitoring the DFG collected by your project, organisations or fishermen involved in retrieval operations will have to report on:

  • Date and time of retrieval of DFG
  • Location of DFG
    • General description: distance from landmarks and/or common place names
    • Chart location (latitude and longitude of location, to the nearest second) or GPS coordinates (to five decimal places)
    • Water depth.
    • Habitat type (e.g. soft bottom, rocky).
  • Nature of DFG retrieved
    • Type of gear: Nets (monofilament gillnet, trawl etc.), Pots/Traps (round or square for crab or shrimp, singular or multiple), Ropes/Lines, Floats, Trawl Doors or other
    • Origin: fisheries (mesh size can be used to attribute gear to a fishery)
    • Number, volume, weight, length of nets and other gear retrieved
    • Condition of gear (frayed nets, damaged gill net panels, bio-fouled etc.)
    • Shape: balled, draped, floating, roped, etc.
    • Cause: abandoned or lost
    • Estimated age of lost gear.
  • Retrieval method employed:
    • Type of retrieval: mechanical and/or with support of qualified divers.
    • Equipment used (vessels, hooks, hand tools etc.).
    • Problems encountered.
    • Suggestions for improvement in method.
  • Environmental impacts:
    • Number and types of invertebrates, fish, birds, mammals entangled or dead in the gear.
    • Degree of incorporation of the gear into the environment.
    • Perceived level of threat of the gear to humans, surface vessels, animals.
    • Environmental impact of removal.
  • Location, type, volume and condition of any DFG that was not retrieved.

The information can also be used to monitor and to evaluate your project and to build raising awareness campaigns about the DFG problem and your project, and to attract support for your project. Establishing a monitoring scheme will help you to more efficiently manage your project in the future. For example, you will be able to make better assumptions on how much gear you can retrieve in the next years. The information gathered could also be useful to policy makers, who may use the information in developing policy measures, and to research institutes, who may wish to use the information to further develop the understanding of the DFG problem.
