Global Evaluation of Shark Sanctuaries

An interesting recent paper evaluating the efficacy of shark sanctuaries, including in The Bahamas. The paper is a little long, but easily accessible. It is straight forward to scroll through sections to find items of most interest (e.g., human uses or conservation awareness). The full paper summary pasted below.

Due to well-documented declines in many shark populations there is increasing […]

Global Feeding Habits of Sharks

An interesting new study using stable isotopes to look at the feeding ecology of more than 5,000 individual sharks across 114 species. The cartoon above does a nice job of characterizing this study, and here is a good summary.

And another: ‘Have Scientists Been Overestimating our Toll on Reef Sharks?’

Shark populations are declining worldwide and  shark awareness and conservation is necessary. However, some interesting news from a recently published paper suggests that we might be overestimating the density of sharks required on reefs to resemble pristine reefs. This is very exciting, as shark researchers and conservationists’ goals are now potentially more realistic. Read more in this short (650 words, […]

Hope for economically important Caribbean reefs sharks in The Bahamas

A guest post from Oliver Shipley at the Cape Eleuthera Institute. Photos courtesy of Sean Williams. Thanks Oliver!

Across the Caribbean, overexploitation has led to growing concern regarding the fate of apex predator populations, particularly sharks, which constitute an important structural component of many marine ecosystems. In 2011 The Bahamas outlawed the commercial fishing, and trade of any shark related […]

What Fish are Left in the Caribbean?

Cool new study by John Bruno’s lab at the University of North Carolina. They surveyed sites across the Caribbean region and use these data to project back to how many fish there used to be before the fishing pressure. Here is a video summary of the paper from the authors, including footage from The Bahamas. Also, some popular press […]

Sharks Can Make You Rich

New socio-economic study on the value of sharks in The Bahamas (paper here). The paper Abstract summarizes the findings well:

Elasmobranch populations in The Bahamas offer a unique juxtaposition to the widespread decline of many species around the world, largely due to management and conservation initiatives implemented over the last 25 years. Several industries have been built around the diverse […]

New Shark Database Launched

‘To unify shark conservation efforts worldwide, marine life experts have just launched a new database containing information on some of the planet’s most threatened sharks.

The online tool, called the “Database of measures on conservation and management of sharks,” also includes information on threatened skates, rays and chimaeras, which are all related to sharks. It was created by FAO-CITES, […]

Do Sharks Associate with Fish Spawning Aggregations?

This new study (see paper here) investigated whether three species of shark utilize deep Caribbean reefs. Shark species studied were Tiger, Lemon and Caribbean Reef sharks. The researchers found that out of the three species, Lemon sharks were consistently found at deep reefs during spawning aggregations. Though this study was done in the U.S Virgin Islands, it would […]
