FONTUS Spec

What is FONTUS?

  • FONTUS is an open standard designed for on-demand gear location marking, retrieval, lost gear recovery, and enforcement in the fishing industry.
  • It supports buoyless (ropeless) fishing gear, where traditional marking buoys and endlines are removed to reduce entanglement risks for marine life such as whales.
  • The system integrates three subsystems:
  • Acoustic devices attached to fishing gear on the sea floor.
  • Shipboard systems that communicate with devices and the cloud.
  • A cloud database that stores and shares gear location and status information.

Key Features of FONTUS

  • Real-time gear location sharing: Gear positions are accessible to fishers, enforcement agencies, and regulators, ensuring safe navigation and preventing gear conflict.
  • Automatic deployment and recovery reporting via RFID detection — no manual reporting needed.
  • Accurate localization of gear with a target accuracy of about 25 feet (8 meters) in high-density fishing areas.
  • Lost gear discovery and recovery supported through acoustic communication and cloud notifications.
  • On-demand release mechanism integration for gear retrieval triggered acoustically and securely.
  • Multi-manufacturer compatibility: Ensures devices from different manufacturers can communicate and interoperate.
  • Environmental considerations: Minimizes acoustic noise and battery usage to reduce marine impact.

What Does It Mean to Be Open?

  • Open standard means FONTUS is publicly documented and available for manufacturers, fishers, regulators, and developers.
  • Enables interoperability between different manufacturers’ gear and systems.
  • Facilitates transparent and real-time data sharing for all stakeholders.
  • Encourages industry-wide collaboration and innovation in on-demand fishing technology.
  • Compliance with international regulations and supports cross-border fisheries enforcement.

Why Use FONTUS?

  • Addresses critical marine conservation issues by reducing marine life entanglements.
  • Prevents gear conflict and economic loss by clearly marking gear locations.
  • Provides a scalable and standardized solution for both inshore and offshore fisheries.
  • Supports enforcement and compliance through real-time data access.
  • Improves fishing efficiency and safety with automated location and retrieval functions.

Additional Benefits

  • Designed to work with existing chart plotters and standard marine navigation hardware.
  • Supports cloud-based tracking, allowing for extensive data analytics and long-term gear management.
  • Accommodates both mobile and fixed fishers by adapting gear location data delivery accordingly.
  • Promotes sustainable fishing practices by integrating environmental safeguards.
