“Fishermen Want Humpback Whales Off Endangered List” from NPR (link no longer active)

Check out this interesting article about a group of Hawaii fishermen asking the federal government to remove northern Pacific humpback whales from the endangered species list. The group says they no longer need the protection because their population has steadily increased since the start of international ban on commercial whaling. Although removing humpbacks from the endangered species list wouldn’t allow this group to start hunting them (they are still protected by the whaling ban) they feel that too many species are added to the list and not enough are taken off.

Malice and grief in Southern waters” from World Fishing and Aquaculture

Fishing can be a dangerous occupation. That is true worldwide, but in areas where there is political controversy, pirates or illegal fishing, it can be much worse. Check out this interesting article about the dangers fishermen face in southern waters.

Scientists map global routes of ship-borne invasive species” from BBC

Scientists have recently developed the first global model that analyzes the movement of invasive species in the ocean. By studying the movements of cargo ships (where many invasive species can catch a ride in the ballast water) the researchers were able to identify hotspots where the invasive species might thrive. Hotspots include Singapore, Hong Kong, and the Panama and Suez canals. The longer the trip, and the colder the destination, the less likely it is that invasive species will thrive.

Sturgeon search” from U Del

Due to overfishing, Atlantic sturgeon (fish sought for its caviar) are now endangered. It is estimated that there are fewer than 300 adults left. Researchers are now trying to learn more about sturgeon migration patterns by using satellites, acoustic transmitters and underwater robots. Hopefully, this knowledge will help fishermen avoid spots where they may unintentionally catch them.

Time to Serve Up Antarctic Marine Reserves, Not Chilean Sea Bass” from Pew Environment

Check out this interesting post about Antarctic toothfish, better known as Chilean sea bass, which is caught in the Ross Sea. Hopefully, the Ross Sea will become the world’s largest marine reserve this summer, but right now it is being dangerously overfished.
