The bloody rödhajen is one of the few species that live out on the west coast of sweden. The sharks, however, have become fewer and fewer in number, and are still in need of support, despite the fact that it has been recorded as viable for the last couple of years. It has managed to reverse this negative trend, and is now a protected species in Sweden – thus, it is forbidden to grab it.
this week, the House of the Sea in Lysekil in sweden, and the united states out of the six akvarieuppfödda bloody sharks in the ocean. An adult female, and five of teenagers”.
the House of the Sea, emitting akvarieuppfödda of sharks each year, and it's a tradition since 2003, and most of it tends to be the audience of the site. But not this year due to the coronavirus.Tagged sharks
To drop out of the akvariefödda the question is, however, not entirely straightforward. The purpose is to strengthen the species.
" to put out a tagged shark in the wild, we want to raise awareness about the lesser spotted rödhajs habits, and the increase in the number of sharks in the ocean. So far, eight of our released sharks have been found. The animals are vulnerable to disturbances, at the same time, they are extremely important for the ecosystem. They are going to need all the help they can get, " says Helen, and the Shield of the akvariechef in the House of the Sea.
the sharks, who have been recovered so far after the release, the majority of the swim to the north, from the gullmar Fjord, to the seas of Norway. According to the House of the Sea was a shark, swimming close to two miles.
the other was found dead, after ten years, it had lived in a total of 14 years of age. The plan is to continue to educate about the hajarnas state, and to work towards increasing the viability of the species.
" It's good that the lesser spotted shark now has increased in number. However, like other marine species, are threatened by unsustainable fishing practices, overfishing, and other exploitation of the oceans and seas. So, the better the protection, the sea needs to be taken. Today live Sweden-up to this, then action needs to be taken, " says Inger Näslund, marine expert at WWF.
the Facts are the sharks of the world
In the marine ecosystem, sharks are top predators in the food chain. Many of the world's shark species are threatened with extinction. The reasons are, above all, to the fierce and uncontrolled fishing for sharks and shark finning and getting caught as by-catch in fishing gear. However, it is also the result of their slow life cycle, get the kids in the reproduction. The latter is, thus, extremely vulnerable to over-fishing and other disturbances, according to the WWF. In Swedish waters, it is primarily bottom trawling for other species, which are causing the hajarnas decline as they get caught in nets as by-catch. The lesser spotted dogfish is one of the few species that live along the west coast of sweden.
