surveillance, using a variety of sensors, monitors freighters, tankers, bulk carriers and container ships as well as fishing vessels. Canada intends to provide, in real time, VMS data, correlated with other sensors and database information, to patrol vessels and aircraft. Electronic logs, two-way communication with fishing vessels, issuing orders, and possibly placing video and other sensors on fishing. Chile Chile has VMS aboard approximately 500 vessels, each vessel being associated with one fishery. Marimsys built the Chilean VMS, but that system was replaced in 2007 with a new one provided by CLS. Chile went from a government-specified VMS to a type-approval system for VMS units in an open market, which drove down costs. Monitored industrial fishing boats limit fishing activities to—generally— from the coast of Chile. This leaves the 5 nm zone for "artisanal" or smaller fishing boats and limits excessive fishing effort being applied to inshore waters. Chile also pioneered in the emission of reports at short intervals. Prior systems had focussed on "where is the vessel" with the provision of hourly reporting. The Chilean system, by dropping the minimum report interval to 8 minutes is capable of determining "what" the vessel is doing. When you see a series of circular positions, they are all at speeds of below and reflect the drift of the current—there is no question, that vessel was purse seining, and the printout of the chart can be shown to the court to demonstrate the fact. Chile is currently the world's largest producer of farmed salmon and has a burgeoning mussel culture industry that is supplying a growing world market. Other fisheries of interest include alfonsino, anchovies, cod, cuttlefish, hake, mackerel, ray, sardines, sea bream, squid, and swordfish. The system is also used to monitor foreign vessels entering and leaving both the EEZ and Chilean ports. Taiwan Taiwan has national and provincial VMS programs, the most active being for Taiwan. It uses both Inmarsat-C and Argos to monitor up to 1200 vessels. Croatia Croatia has implemented its VMS on 256 vessels in 2007. The BlueTraker VMS devices, supplied by EMA, enable utilization of both satellite and GPRS communication channels. VMS software solution is developed and supported by GDI GISDATA, a Croatian company. Croatian Fisheries department uses it to identify and track the country's large fishing vessels. This information can be used for monitoring boat activity and as evidence for law enforcement.
