Ban on fishing of mako sharks reached at meeting

At the annual meeting of the International Commission for the Conservation of Atlantic Tunas (ICCAT) last week, North Atlantic fishing nations have pledged to ban catches of the shortfin mako shark.

The efforts to secure the ban was led by the UK, Canada and Senegal. The move means that the countries agreed to end overfishing immediately and to gradually achieve biomass levels that were enough to support maximum sustainable yield by 2070 for the species, according to an article in The Guardian.

Study sheds light on plankton in Gulf of Mexico

Plankton is admittedly not the most exciting life form in our oceans. Nonetheless, a team of researchers have been taking a closer look at plankton life in the Gulf of Mexico.

Their study has resulted in the publication of a paper in the Science Advances journal.

The researchers focussed on the subtropical waters off Florida, in the Gulf of Mexico, using high-speed underwater imaging technology and advanced machine learning approaches.

Will humans ever understand what these cetaceans are saying?

Will we learn to speak whale?

Project CETI is a nonprofit organisation applying machine learning and robotics to listen to and translate the communication of whales. The organisation is working to develop a deeper understanding of the complex system of communication that sperm whales use and share this understanding with the world.

UK 'Ghost Gear Coalition' formed to reduce diving team response time

The solution is straightforward, if you have the relevant knowledge at your fingertips. Just contact one of the many NGOs around the world, such as 'Ghost Diving', who work to combat this problem internationally, and let them know the details of the ghost gear that needs to be recovered.

Why do fish rub themselves against a shark?

Fish rubbing themselves against a shark's body may sound as if they have a death wish, but this is precisely what some fish have been spotted doing. And it turns out that such behaviour is more widespread and frequent than one would think.

A study led by the University of Miami (UM) Shark Research and Conservation Program at the Rosenstiel School of Marine and Atmospheric Science uncovered over 40 instances of fish rubbing themselves against a shark’s skin in over ten locations around the globe.

While chafing has been well documented between fish and inanimate objects, such as sand or rocky substrate, this shark-chaffing phenomenon appears to be the only scenario in nature where prey actively seek out and rub up against a predator.
