Without a Worldwide Unique Vessel Identifier (WUVI) database, the International community has largely relied on data in self-created combined vessel lists for spatiotemporal mappings of fishing presence, effort, and footprint. Projects match fishing vessel registration identifiers to their alleged AIS MMSI numbers using these vessel lists. This study aims to prove that this method has yielded a large number of erroneous ship identification references. Global Fishing Watch, one of the largest vessel identification projects, is crosschecked with the vessel data that the study gathered and found that it suffers from major flaws and biases. Such errors put at risk both the creditability of the GFW and private/independent fisheries monitoring control & surveillance (MCS) initiatives. Not only should projects use more scientific responsibility, but a worldwide database could also help end the data-gathering methods that brought these mistakes about.

This report discusses the rapid expansion of squid fishing in the Indian Ocean Tuna Commission (IOTC) Convention Area. The vessels appear to operate exclusively in the high seas, avoiding exclusive economic zones (EEZs) and therefore falling within an area beyond national jurisdiction (ABNJ).
The area of operation, although physically within the area covered by the regional fisheries management organisation (RFMO), the IOTC, does not fall within its area of competence as only tuna and tuna like species are included within the IOTC mandate. The squid fishery presented in this report, based on analysis of data from January 2015 to April 2017 is therefore unregulated.
Squid are important prey for 12 predatory species including significant species such as bigeye tuna and swordfish. A clear understanding of sustainable yields is needed and management frameworks are required to sustainably manage this fishery.
