Illegal fishing is becoming unveiled for general public as two environmental activist groups have built the first global surveillance system that can track large fishing vessels anywhere in the world with the support of satellite information from SpaceQuest and the technology of Google.
The prototype of this latest tool to fight illegal fishing, the Global Fishing Watch system, was announced today at the IUCN World Parks Congress in Sydney.
The project was led by marine conservation advocacy group Oceana and the software was developed by SkyTruth, a small non-profit that specializes in using remote sensing technologies to map environmentally sensitive activities.
Oceana estimated that dark fleet activity costs between USD 10 billion and USD 23 billion in global losses every year, The Verge points out.
The Global Fishing Watch allows anybody with an Internet connection to check, at no cost, the live tracks of more than 140,000 ships and see where they have been for the last year.
“Then you'll actually be able to see someone out there fishing within hours to days,” Jackie Savitz, Oceana’s VP for U.S. oceans told Wired. This is fast enough to act if the fishing is happening illegally, such as in a marine protected area.
The system uses data from the automatic identification system (AIS) that is applied to ships of more than 300 gross tonnes. AIS broadcasts information on a vessel's identity, type, location, course and speed every two to 20 seconds and every three to six minutes while at anchor.
It is illegal for a ship to turn AIS off or use a false identity.
The group says that has figured out a "behavioural algorithm" that allows it to add ships to the list that "are behaving like fishing vessels despite how they identify themselves".
The new system can spot when the AIS is illegally switched off because there are blanks in the ship's tracks.
Paul Woods of SkyTruth notes that the system does pick up some non-fishing activity as false positives.
Nevertheless, some say that the false negatives are the most important. Global Fishing Watch still misses most of the activity of the so-called dark fleet: smaller fishing boats that are not required to use AIS and rogue fishers who turn their radios off before they enter restricted zones.
However, the model is able to detect erratic AIS transmissions. Savitz said. “If we see pings from a vessel every hour for a month, then it goes silent, but suddenly comes back on weeks later, we can pick that up and possibly trigger enforcement against them for not transmitting as they are supposed to.”
It can also be used to identify intermittent activity in the about 6600 no-take marine protected areas or reserves around the world.
"Besides providing a nearly real-time window on the worldwide activities of the world's commercial fishing fleets, Global Fishing Watch will also empower citizens to help identify illegal fishing vessels," Oceana highlights.

Balai Besar Penelitian dan Pengembangan Pengolahan Produk Kelautan dan Perikanan (Research and Development Center for Marine and Fisheries Product Processing and Biotechnology, BBP4KP) is the research center belonging government to make a product from fisheries and marine material. Many research is doing there include food product and nonfood product.
The term fish processing refers to the processes associated with fish and fish products between the time fish are caught or harvested, and the time the final product is delivered to the customer. Although the term refers specifically to fish, in practice it is extended to cover any aquatic organisms harvested for commercial purposes, whether caught in wild fisheries or harvested from aquaculture or fish farming.
Fish processing can be subdivided into fish handling, which is the preliminary processing of raw fish, and the manufacture of fish products. Another natural subdivision is into primary processing involved in the filleting and freezing of fresh fish for onward distribution to fresh fish retail and catering outlets, and the secondary processing that produces chilled, frozen and canned products for the retail and catering trades.
