The IMCS Network Library is a curated collection of resources that support those working in fisheries MCS, compliance and enforcement. It brings together practitioner international instruments, guides, technical papers, reports and reference materials. 

The Library provides easy access to trusted, practical information designed to strengthen capacity, improve coordination and inform decision-making across our global community.
 

The IMCS Network, in collaboration with TMT, has developed a series of MCS Practitioner Guides designed to strengthen operational understanding across major industrial fishing, support vessel and gear types. 

These guides provide practical, field-ready information to assist those working directly in MCS and compliance. They serve as valuable reference tools for operational staff, helping to build technical capacity and promote consistent approaches across jurisdictions. 

Beyond frontline practitioners, the guides also support trainers, analysts and partners across the broader fisheries MCS community and contributing to more effective, informed and coordinated compliance efforts worldwide.

Combined Regional Authorised Vessels Tool

The CRAVT automatically combines vessel-related data and information from several RFMOs and RFBs. The CRAVT can be used to search for specific vessels or browse groups of vessels including by flag, vessel type or RFMO or RFB. The CRAVT identifies where differences exist between RFMO or RFB records for a specific vessel. Users may also search Vessel Contacts (vessel companies and vessel masters) for a specific vessel.

Triton explores the connections between industrial fishing vessels at sea and the companies that ultimately control them. This tool is free to use and lets users visualise network graphs and identifiers from companies and individuals that are connected to fishing vessels. If networks do not appear fully built out or you require primary documentation please reach out to C4ADS.

Skylight

Skylight is a tool for surfacing suspicious events in the maritime domain. Skylight is focused on addressing IUU fishing but can be applied to many types of maritime crimes. Skylight was developed to identify suspicious vessel behavior and alert authorities who can investigate and take compliance action when necessary. Skylight strives to help analysts focus their time on the most suspicious activities in their domain rather than analyzing all vessels and vessel tracks.

Combined IUU Vessel List

The Combined IUU Vessel List provides the best available, up to date information on all fishing vessels that appear on the IUU vessels lists published by RFMOs and related organisations. The Combined IUU Fishing Vessel List merges all available RFMO IUU vessel list sources into one list, that provides a single reference point to identify whether a vessel has been IUU listed. Vessels that have been IUU-listed in the past and subsequently delisted (for example as a result of a change in ownership, or because the vessel is no longer in service) are retained on the site, so that it contains a full historic record of IUU-listed fishing vessels.

 Carrier Vessel Portal

The Global Fishing Watch Carrier Vessel Portal can help compliance, MCS and enforcement officers analyse the activities of carrier vessels that transship catch from commercial fishing vessels and land this catch into ports around the globe for processing and further trade. The portal can be used to verify transshipment activities and identify when such activities are not being adequately reported.

Global Fishing Watch Map

The Global Fishing Watch map was the first open-access online platform that provided visualisation of fishing activity at scale. It supports dynamic filtering and different ways of interacting with the billions of data points it displays (both AIS and VMS data for specific areas). It summarizes data in dot density maps and vessel track maps. Dot density maps use shapes to show the presence of vessels and can be used to examine vessel density and movement. Vessel track maps use lines to represent the tracks of vessels and can be used to analyze the activities of specific vessels.

Marine Traffic

Marine Traffic gathers data from more than 18,000 AIS equipped volunteer contributors in over 140 countries around the world. Information provided by the volunteer AIS equipment includes vessel unique identification, position, course, and speed. This information is displayed on the website in real time. Marine Traffic also displays vessel photos that are submitted by registered users and are included in the Marine Traffic Photo Directory.
