Research at the ARC Centre of Excellence for Coral Reef Studies at James Cook University, Queensland, Australia has revealed that global warming is affecting large reef fish.
Researcher Dr Jacob Johansen was part of the study that looked at the impact of global warming on the commercially important fish species, coral trout, suggesting that increasing ocean temperatures may cause large fish to become lethargic.

John Wang, a fisheries researcher at the University of Hawaii at Manoa, USA and his colleagues teamed up with fishers in Baja California Sur, Mexico, to experiment with reusable, battery-powered UV LEDs for use as a turtle deterrent. Acording to previous studies, turtles can perceive light across the visible spectrum as well as into the ultraviolet.
The researchers stated that securing UV lights at five-meter intervals on fishers' gill nets, lowers accidental sea turtle capture, or bycatch, by around 40 percent, compared with control nets with inactivated LEDs.
