Hakiki kila swali8 maswali

Majibu na maelezo huonekana unapojibu maswali.

  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
