Vessels in the Atlantic Sea Scallop fishery are required to use turtle deflector dredgesin certain areas and seasons, which block the entrance to the dredge and deflect turtles over the top of the frame.

In Shark Bay, Western Australia, an investigation was conducted into the biology of a tiger shark named Galeocerdo cuvier. Purse-seine are the huge nets used in commercial fishing and this figure may seem a little small, but the authors of the study noted the current sampling coverage was insufficient to give any reliable estimate for low-occurring species, such as marine turtles and some oceanic pelagic sharks. Continuing to develop these ideas within our oceans will enable us to strike a balance between achieving sustainability and suiting the needs of our population. Fishing Gear and Risks to Protected Species. For example, it has been estimated that global longline fisheries kill somewhere between 160,000 320,000 seabirds annually. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Enter your email address to follow this blog and receive notifications of new posts by email.

Long-liners have relocated to Hawaii as swordfish populations in the Atlantic have declined. This can lead to a decrease in the population of these species and can be very harmful to the environment. This is contributing to habitat loss and population loss, with more and more species being placed on the endangered list. The tuna fishery is one of the best managed fisheries in the world, according to the UN Code of Responsible Fishing[citation needed], but has been criticized by others[who? When nets are dragged along the seabed they not only catch the species that is being targeted, but they also rip up the seabed itself. Once hooked, the fish may become vulnerable to predators and may even die if they are landed. [10] These activities, however, are not randomly spread across the vast oceans, but rather are highly spatially concentrated.
