spawning

Chinook make their way up the Klamath River every year, but fewer and fewer arrive in the spring.

Various concerned groups have been petitioning NOAA Fisheries to list spring-run Chinook salmon in Oregon and Northern California for over a decade.

By growing mountainous star corals in the lab and outplanting them to dying reefs, we were able to grow sexually mature corals that could help reef recovery.

Novel technologies establish a new paradigm for global coral reef restoration, with in situ spawning of mature, environmentally resilient corals in five years instead of decades.

Our novel technique involves planting several small fragments of slow-growing corals onto dead coral heads. The fragments eventually fuse, forming a large colony in a fraction of the time that it takes wild corals to build reefs.

The fish continue to spawn over a large area despite a drop in their numbers, a study finds.

Stony coral tissue loss disease has already affected 80 percent of Florida’s coastal reef system. Now, a huge team of responders is working to slow its spread and prepare for future restoration efforts.

Researchers recovered audio recordings of the fish’s mating calls in the eye of the storm.

Researchers document the loudest sound ever recorded in fish.

Chemical cues dispersed by mussel eggs may attract sperm that are their perfect match.
