Going in the water again: 'Jaws' boat clone supports sharks

Jul. 21, 2020 4:36 PM EDT

The Orca is headed back to the waters of New England, but this time, its mission isn't to hunt sharks. It's to help save them. A group of ocean advocates and movie buffs is turning an old lobster fishing vessel into a replica of the Orca, the boat captained by the grizzled shark hunter Quint in...

Conservation study shows lemurs, whales nearing extinction

4 great white sharks detected near Rhode Island shore

Jul. 8, 2020 12:13 PM EDT

PROVIDENCE, R.I. (AP) — Researchers at the Atlantic Shark Institute detected four great white sharks Wednesday in the waters near Block Island, Rhode Island.

In this Aug. 4, 2019 photo provided by Taylor Williams, a new species of seaweed covers dead a coral reef at Pearl and Hermes Atoll in the remote Northwestern Hawaiian Islands. Researchers say the recently discovered species of seaweed is killing large patches of coral on once-pristine reefs and is rapidly spreading across one of the most remote and protected ocean environments on earth. A study from the University of Hawaii and others says the seaweed is spreading more rapidly than anything they've seen in the Northwestern Hawaiian Islands, a nature reserve that stretches more than 1,300 miles north of the main Hawaiian Islands. The algae easily breaks off and rolls across the ocean floor like tumbleweed, scientists say, covering nearby reefs in thick vegetation that out-competes coral for space, sunlight and nutrients.

To capture catfish forced to the surface by a low-frequency electric current, researchers in a fast chase boat swoop in with dip nets to scoop them up before they get away, Wednesday, June 10, 2020 near Leon, W.Va. (John McCoy/Charleston Gazette-Mail via AP)

Researchers use 'shocking' method to capture catfish

Jul. 4, 2020 10:01 AM EDT

LEON, W.Va. (AP) — With its two spider-like electrodes dangling into the water, the big boat idled along slowly. “There!” one of the men on the boat yelled, pointing toward a spot 20 yards away where a catfish skittered across the surface. A smaller boat zoomed toward the fish, and a man in...

This 2014 microscope photo provided by Dr. F. Dahlke shows 1.5 mm diameter eggs of Atlantic cod (Gadus morhua). Global warming looks like it will be a far bigger problem for the world’s fish species than scientists first thought, since a study led by Dahlke released on Thursday, July 2, 2020 shows that when fish are spawning or are embryos they are far more vulnerable to hotter water.

Fish more vulnerable to warming water than first thought

Jul. 2, 2020 2:05 PM EDT

Global warming looks like it will be a bigger problem for the world’s fish species than scientists first thought: A new study shows that when fish are spawning or are embryos they are more vulnerable to hotter water. With medium-level human-caused climate change expected by the end of the century, the...
