AIS is a maritime tracking system that automatically broadcasts vessel position, course, speed, and identity information. This real-time data exchange creates a comprehensive picture of maritime traffic, enabling vessels to navigate safely and operate efficiently.
Operates through land-based receivers with a range of 30-50 nautical miles from shore.
Primary characteristics:
· High accuracy positioning
· Real-time updates
· Cost-effective implementation
· Limited to coastal waters
· Ideal for near-shore fishing operations
Operates through a network of satellites providing global coverage for vessel tracking.
Primary characteristics:
· Worldwide coverage capability
· Essential for offshore operations
· Update intervals of 15-30 minutes
· Higher operational costs
· Required for deep-sea vessels
· Independent of shore-based infrastructure
Operates through vessel-to-vessel signal relay, creating an extended network.
Primary characteristics:
· Enhanced coverage in busy fishing grounds
· Self-improving network effect
· No additional infrastructure needed
· Effectiveness depends on vessel density
· Ideal for popular fishing areas
· Cost-effective supplementary coverage
Modern AIS systems do much more than just show other vessels. Here's what they can do for your fishing operation:
Tracking Good Fishing Spots:
· See where other vessels are making their catches
· Identify productive depths by combining AIS tracks with depth charts
· Learn from historical fishing patterns in your areas
· Find new grounds by analyzing fleet movements
Working Better as a Fleet:
· Know exactly where your other vessels are fishing
· Avoid fishing in areas that were just worked
· Share information about good spots between vessels
· Save fuel by better coordinating vessel movements
When choosing an AIS system for your vessel, ask yourself:
· Where do you fish most often? Near shore or out at sea?
· How many other vessels do you work with?
· What kind of fishing information do you want to track?
· What's your budget for both equipment and monthly fees?
Remember: The cheapest system isn't always the most cost-effective. A good AIS system should pay for itself through better fishing efficiency and fuel savings.
The technology continues to evolve, with improvements in satellite coverage, data analytics, and integration capabilities. These advancements will further enhance the value of AIS for fishing operations.
· AIS provides essential safety and operational benefits
· Different coverage types suit different fishing operations
· Proper system selection is crucial for operational success
· Integration with other technologies maximizes value
· Future developments will enhance system capabilities
