Originally designed for AquaTech’s series of surf housings, the leash comes in handy at times when an underwater photographer needs both hands free but does not wish to release pricey camera gear into the abyss.
Scientists at Pennsylvania State University and the University of California, Santa Barbara have discovered that when fishermen selectively catch large and medium-sized parrotfish at coral reefs facing decline due to climate change, algae has a better chance of growing and overtaking the corals.
Nonetheless, according to the research, the reef’s biomass is maintained. This is because even with less of the large and medium-sized parrotfish, there would be many smaller parrotfish that would take their place.
Whilst nowadays most underwater shooters do their white balance correction during postproduction of images, there are still many shooting situations (such as several different light sources present in one shot) in which doing it “old school” comes with clear advantages and optimized workflow.
The Chinese government has imposed a 10-year commercial fishing ban in the Yangtze River to combat "across-the-board" declines in the populations of rare species like the Chinese sturgeon.
As it came into effect on 1 January 2020, it is hoped that the ban will tackle the problems of dwindling fish stocks and declining biodiversity in the 6,300m river. It will be applied at 332 conservation sites along the river and be extended to cover the main river course and key tributaries by 1 January 2021.
