Cyanide fishing is the practice of capturing fish using a potent, inexpensive poison called sodium cyanide.

As one of the few institutions that creates detailed logs of all video produced with the submersibles, HURL has created and built up a knowledge base that is featured in a photo-guide of all the organisms one might encounter in the deep-sea around Hawai‘i.

“The particular violet coloration might just have evolved by chance, and must not necessarily have a very specific function or reason aside from being a general visual signal for recognition,” said Henrik Freitag, the author of the study that is found in the latest issue of The Raffles Bulletin of Zoology.
CoralVue’s upcoming 4-stage 100 GPD RODI unit
CoralVue has been hard at work putting together a new RODI unit for their product line. As mentioned, this unit is a 100 GPD 4-stage system that comes with an integrated controller and pressure pump.
Picture this: It’s late Saturday night and you hear a noise coming from your fish room. Upon investigation, you find your return pump is buzzing loudly and not pumping water. “Huh? What’s going on here?!”…
If susceptible table and branching species are replaced by mound-shaped corals, it would leave fewer nooks and crannies where fish shelter and feed.
“Coral reefs are sometimes regarded as canaries in the global climate coal mine – but it is now very clear than not all reef species will be affected equally,” explains lead author Professor Terry Hughes, director of the ARC Centre of Excellence for Coral Reef Studies at James Cook University.
New eel species: Peri’s Snake Eel (Myrichthys paleracio)Photo by Mark Atwell.
The new species of snake eel is now know as Peri’s Snake Eel (Myrichthys paleracio) and is unique from other snake eel species because of its white and brown coloration, vertebrae number, and it’s elongated body.
Ph.D. student Rachel Silverstein analyzed 39 coral species from DNA collected in the Indo-Pacific and Caribbean collected over the last 15 years.
A new study by scientists at the University of Miami’s Rosenstiel School of Marine & Atmospheric Science suggests that many species of reef-building corals may be able to adapt to warming waters by relying on their closest aquatic partners — algae.

Phage therapy is the use of bacteria-specific viruses (called bacteriophages) for treating bacterial infections. Bacteriophages are very bacteria specific (more so than antibiotics) and can be highly effective in instances where antibiotics are not practical, such as in open systems like the ocean.
Alpheus lottini, a snapping shrimp.
The same holds true, researchers have recently learned, when different species of crabs (genus Trapezia) and snapping shrimp (Alepheus lottini) in the central Pacific band together to defend their coral homes from hungry seastars.
