METHOD-2 - Hoop Net Requirements

This protocol establishes minimum standards for hoop net deployment and monitoring to prevent drowning of captured organisms. The above-waterline positioning and flotation requirements create dual safeguards against trap submersion. Permit holders should avoid deployment when weather conditions could compromise trap security or animal welfare.

Protocol Requirements

Equipment Deployment and Security

  • Condition METHOD-2.1
    Each hoop net shall be secured in a position whereby part of the trap remains above the water line at all times during deployment.
  • Condition METHOD-2.2
    Each hoop net shall be anchored to prevent movement from the deployment location through attachment to a fixed object such as a tree or by securing with t-posts, rebar or PVC pipe driven into the substrate.
  • Condition METHOD-2.3
    Each hoop net shall include a flotation device consisting of pool floats or air-tight plastic bottles that prevents the trap from becoming fully submerged.

Monitoring and Animal Welfare

  • Condition METHOD-2.4
    Each hoop net shall be checked at least once every 24 hours during deployment periods.
  • Condition METHOD-2.5
    All captured organisms shall be removed from hoop nets immediately upon discovery during monitoring checks.

Equipment Identification

  • Condition METHOD-2.6
    Each hoop net shall be tagged with a waterproof tag displaying the researcher's name, contact phone number and Scientific Research Permit number.

Weather and Safety Restrictions

  • Condition METHOD-2.7
    Hoop nets shall not be deployed when high amounts of rainfall are forecasted that could compromise trap security or animal welfare.

Incident Reporting

  • Condition METHOD-2.8
    The permit holder shall notify Texas Parks and Wildlife Department within 24 hours of discovery of any trap-related mortality.
