Whale shark distributions are predicted to shift up to 1,000 km by 2100, due to climate change, putting them at increased risk of collisions with global shipping. Read the new paper co-authored by @llsousa84 and colleagues 👉 nature.com/articles/s41558-0…

Our researchers have led a new study which suggests #ClimateChange could increase the threat posed to endangered whale sharks, as they are driven into new habitats crossed by busy shipping lanes. Find out more 👉 brnw.ch/UoS_news_whale_shark…

Replying to @DrNeilHammer @cbcoceansguy @TheSimsLab
@TheSimsLab & I discuss the importance of this study & highlight its findings. It’s clear that rather than focusing on finning alone, the next wave of shark conservation will require reducing overall shark mortality amid threats from global change, including global warming.

Replying to @DrNeilHammer @cbcoceansguy @TheSimsLab
While discouraging, the study does report some positive outcomes: namely, regulations that appeared to successfully reduce shark mortality, such as regional shark fishing prohibitions or retention bans, that is, policies that directly reduce the number of sharks being killed.

Replying to @DrNeilHammer @cbcoceansguy
While the demand for shark fins was historically the greatest threat to sharks, anti-finning regulations did not prevent sharks from being killed, nor did it even prevent fins from being removed and sold, so long as the rest of the shark was not discarded at sea.

Despite anti-finning laws aimed at conserving sharks, a recent study by @cbcoceansguy & colleagues have revealed that global shark mortality rates have surprisingly risen over the past decade, driven in large part by increased demand for shark meat. This is a huge wake-up call.
