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.
