•From VOA Learning English, this is the Environment and Science Report.

•Experts estimate that one out of every five fish sold was caught illegally. They say the illegal fishing market is worth $23.5 billion a year. It threatens food security and hurts the environment.

•Officials are using new observational technology to fight illegal fishing.

•"Hello to everybody. Thank you for taking the time to join us here in Harwell (UK) in the Operations Center to what we call ‘Project Eyes on the Seas,'" Long said.

•That is Tony Long. He leads the Ending Illegal Fishing program for Pew Charitable Trusts. The group created Project Eyes on the Seas. Large three-dimensional images of a globe can be seen on a video that plays behind him.

•"It looks different from what you might expect because this globe only shows you the vessels (boats) that are coming into this system from a live automated information system or AIS," Long said.

•The screen shows there are 120,000 fishing boats that have AIS. They are required to have the technology. But those who are fishing illegally often turn it off. The technology does not tell observers when that happens. Project Eyes on the Seas combines satellite information with secret government records on every ship's past activities.

•"The same system the fishing vessels use to predict where the fish are going to be, we can bring that environmental source into this data," Long said.

•Mr. Long says that permits investigators to understand exactly where the fishing boats are operating.

•The Pew team gives the information it gathers to port officials to help them decide if they should take action against a ship.

•The Pacific island nation of Palau was an early user of the technology. Palau has one of the richest fishing areas in the world, and wants to protect it. Last year, it announced a plan to ban commercial fishing in a 630,000 square kilometer area.

•K.B. Sakuma is a special adviser to the president of Palau. He says Palau is trying to deal with a recent increase in illegal, unsupervised and unreported fishing.

•"And it's come to a head in the last year or two, where [from] our southern island in the evening you can see on the horizon just dotted lights of these illegal fishermen that come into our waters, fill their holds with our fish, our resources, our food security..." Sakuma said.

•Mr. Sakuma hopes the information from the project will help Palau fight fishing piracy.

•And that's the VOA Learning English Environment and Science Report.
