Galapagos shark, Carcharhinus galapagensis

Scientists urge Brazil to take a stand on protecting marine life

Brazil fisheries have no bag or size limits for any species of fish and even the most basic fisheries statistics, such as the numbers and weights of fish being caught, are a blank space. The newly published Red List of Brazilian species at risk from extinction, identifies 83 types of marine animal aslo commercially exploited by fisheries. The Galapagos shark is an example of a keystone species thought to have been fished to regional extinction due to decades of nonexistent fisheries regulations. This species is one of many that could have greatly benefited from management plans that help reduce by-catch and prevent the overexploitation of fishing stocks.

Great white shark

Like Sharks? Volunteer with Great White Shark Project

The 1974 film “Jaws” immortalized the Great White but also did more damage to the image of the Great White Shark than they could ever do themselves. Despite all the fear and celebrity, very little is known about these aquatic behemoths. Scientists who have studied Carcharodon carcharias (jagged tooth) aren’t even sure how they reproduce. […]

SCUBA Fish Count

Silent divers count more fish

SCUBA divers underestimate the amount of life in heavily-fished areas, a study suggests. Scientists from Australia compared fish counts by SCUBA divers—who produce noisy bubbles—and divers using silent rebreathers. They found little difference in counts between the two in Marine Protected Areas (MPAs), where the fish weren’t frightened of the divers. In more heavily fished […]

Grey Reef Shark, Carcharhinus amblyrhynchos

Shark-counting divers become citizen scientists

Divers monitor reef shark numbers as accurately, and cheaper, than automated tracking tools, a study suggests. Shark populations are thought to be declining globally, but a quick search of the IUCN’s Red List shows that for 67% of shark species the population trend is unknown. It’s difficult to monitor shark numbers due in part to […]
