The immense size, strength, and stature of this largest living land animal has intrigued people of many cultures for hundreds of years.
In reality, they have much more to fear from us than we do from them. Because of our actions, many species of sharks are on the verge of extinction. Fins from a blacktip shark.
David Shiffman The life history strategy of sharks is very different from that of other commercially exploited fishes, and this makes them more vulnerable to overexploitation.
While few sharks are targeted for their flesh, which is considered unpalatable except for a few species, most species are targeted for their fins.
The fins, which have absolutely no meat, flavor, or nutritional value whatsoever, are made into an Asian delicacy called shark fin soup.
They provide only texture to the spiced chicken broth. While it is impossible to know exactly how many sharks are killed in this global, largely unregulated fishery, the best scientific estimates we have say that the number is as high as 73 million each year.
Though few fisheries are blameless from a bycatch perspective, particular culprits include the shrimp trawling fishery, the tuna purse seine fishery, and the billfish longline fishery. Since sharks serve as apex predators in most marine ecosystems, their declines pose major troubles both to the environment and to the countless humans who depend on that environment for food and to make a living.
The problem is a major one, and we need to solve it. We must focus on the goal, and work towards it! I expect that many of my conservationist friends will disagree with parts of it, and I look forward to a lively discussion.
Sharks are being harvested or killed accidentally as bycatch at wildly unsustainable rates. This needs to stop, and sharks need some strong legal protections to ensure this.
The form that these legal protections will take is the subject of much debate. A very few countries like Palau make fishing for sharks in any form illegal in their territorial waters. Hawaii now bans the selling, purchasing, or possession of shark fins within state boundaries. However, most countries have no legal protection at all for sharks, and the number of species with worldwide protection at least on paper, since these are difficult to enforce in the middle of the ocean can be counted on one hand.
I do not object to the sustainable harvest of sharks for food. Sustainably harvesting animals that have so few young so late in life is extremely difficult, and most times that it has been tried, the fishery has collapsed within a few decades.
However, for me to be satisfied, the world of commercial fishing is going to need to undergo some drastic changes. The goal for finning While I can accept sustainable fishing for some shark meat, I object to the shark fin soup fishery.
In most parts of the world, this fishery is brutal, wasteful, and unsustainable.
Sharks of any species and size have their fins cut off, and the rest of the animal is dumped overboard to bleed to death or drown- all to provide texture to a delicacy for the rich.
The few countries that have shark finning regulations at all have different strategies to manage it. Some, like Canada, require that fishermen land the rest of the shark in addition to the fins not attached to each otherand they enforce this by weighing total fins and total shark carcasses.
This is silly, because different shark species can have a drastically different fin-to-body weight ratio. Other countries require that fishermen land sharks with the fins still attached, which is better and is starting to become the standard. I would feel differently if fishermen targeted only certain species of a certain size instead of every shark they find.
As it stands, though, my goal for the shark finning fishery is its complete abolition. Fins that are provided to the marketplace via well-regulated comprehensive shark fisheries are a separate issue.
David Shiffman The goal for bycatch The threat sharks face from bycatch is harder to regulate. In some cases, simple gear modifications can minimize the amount of sharks caught without greatly influencing the catch of target species.
In other cases, simply placing gear in slightly different locations or depths can greatly reduce the number of sharks caught accidentally. Some of these changes have been made already, most have not been.White Shark abundance-not a causative factor in numbers of shark bite incidents.
