Protection of species

In Ireland, new regulations giving the basking shark the "protected wild animal" status under the Wildlife Act came into effect on 9 October. The order was signed by Minister of State for Heritage Malcolm Noonan, and Minister for Agriculture, Food and the Marine Charlie McConalogue. This legislation was heavily supported by the Irish Basking Shark Group (ISBG), an international network of researchers, educators, and community representatives founded in 2009.

Fin whales (Balaenoptera physalus quoyi) of the Southern Hemisphere were brought to near extinction by 20th-century industrial whaling. For decades, they had all but disappeared from previously highly frequented feeding grounds in Antarctic waters. Researchers estimate that by the time whaling was banned in the 1970s over 700,000 fin whales had been killed.  

The great hammerhead shark is categorized as “critically endangered” by the International Union for Conservation of Nature. That’s the designation just before “extinct in the wild.” The species is highly threatened with extinction.

To that end, the Center for Biological Diversity has submitted a petition urging the National Marine Fisheries Service to protect the great hammerhead shark under the Endangered Species Act.

The ban does not apply to people with permits issued by the state Department of Land and Natural Resources (DLNR), shark fishing for public safety, sharks captured for self-defence, or sharks taken outside of state marine waters with required documentation.

According to Act 51, the conditions of non-commercial permits for the take of sharks “shall include native Hawaiian cultural protocol, size and species restrictions, and a prohibition on species listed as endangered or threatened.”

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.

Equipped with an autonomous hydrophone, the buoy's function is to conduct for the first time real-time acoustic monitoring of the water's cetaceans to assess how oceanic noise pollution affects them. 

Deployed as part of the Smart Whale Sounds project, it will also track the distribution and behaviour of whale species in real-time and be used to train machine learning models to identify different species' calls. 

Shark fishing was completely banned in the Maldives in 2010 so when the country announced plans to discuss legalising the practice again, it created a massive backlash from the international community.

Sharks have always been a valuable tourist attraction in the small island nation and the declining status of shark fisheries, exacerbated by unresolved conflicts with other stakeholders led to the declaration of total shark fishing ban in 2010. With the shark fishing ban in place, sharks are now caught as bycatch in the Maldivian fisheries.

The Lost Shark, Carcharhinus obsoletus, is already extinct, and others that are expected to follow soon include four species each of hammerhead and angel sharks, from the world’s most threatened shark families. In spite of all the press that shark conservation has received in the past two decades, no effective protection of sharks has been established, no sharks have been saved, and their decline into extinction is ever more apparent.

Knowledge of the habitat use and migration patterns of large sharks is important for assessing the effectiveness of large predator Marine Protected Areas (MPAs), vulnerability to fisheries and environmental influences, and management of shark-human interactions.
