AI in Commercial Fishing Fleets Quiz

Answers and explanations appear as you take the quiz.

1. Which information does AIS contribute to a fishing-vessel movement analysis?
   • An underwater count of every fish
   • A direct record of each net's contents
   • Vessel position and movement messages
   • An assay of water salinity
2. In NOAA's EcoCast example, how can modeled species probabilities support bycatch reduction?
   • By comparing potential target-catch areas with modeled protected-species risk
   • By guaranteeing that no protected species can be caught
   • By certifying every vessel's catch as legal
   • By identifying every individual fish underwater
3. What can camera-based electronic monitoring contribute to a fisheries program?
   • A universal replacement for every observer duty
   • A direct measurement of fish population size everywhere
   • An automatic legal certificate for every trip
   • Recorded imagery that supports catch documentation and review
4. Why is an AIS reception gap insufficient evidence that a fishing vessel intentionally hid illegal activity?
   • Every gap proves the vessel reached port
   • Coverage and signal interference can also explain missing received messages
   • AIS gaps show exact catch quantities
   • No vessel ever intentionally disables AIS
5. Which data combination does NOAA describe for its EcoCast fishing-risk maps?
   • Species observations together with environmental information
   • Only vessel purchase prices
   • Only the number of registered crew members
   • Only a list of harbor street names
6. What does a Global Fishing Watch apparent encounter between vessels establish?
   • Confirmed cargo transfer in every case
   • Proof that both vessels violated fishing law
   • A movement-pattern event that may need further investigation
   • An exact count of transferred fish
7. Why can satellite synthetic aperture radar complement AIS-based fishing-fleet monitoring?
   • It obtains a legal authorization directly from every vessel
   • It can detect vessels without requiring an AIS message from them
   • It identifies the exact species in every hold
   • It only works when each detected ship transmits AIS
8. A fishing vessel matches a public authorization list. What does that match fail to prove on its own?
   • That an authorization record exists
   • That the vessel has been linked to a record
   • That there is information to examine
   • Compliance with all species and catch-quantity restrictions
