Talk:Bottom trawling

Untitled

Deep sea trawling has a long history of opposition, dating back to the 12th century, where British fishermen petitioned against the technique due to the extreme devastation the nets did to both the fish and the ocean floor. During this time the technique was only used through simple sailing boats. Regulation of trawling by the British was one of the important motivators for that country and others to extend jurisdictional claims beyond the traditional three nautical mile distance.

This whole thing looks iffy, for a bunch of reasons:

• Who petitioned?
• To whom did they petition?
• Where in Britain did this happen?
• Is the above mention of regulation of trawling also a 12th century thing, or a modern one?

A source for some or all of the above would be nice. --Kfor 22:35, 23 November 2006 (UTC)

I didn't buy this either, but I came across mention of the wondyrchoum in a book, did a bit more digging, and turns out it really did happen - not quite the 12th century, but they were in the right ball park. I've added what I could find, with a reliable reference (this article could do with a few more of those!). Anilocra 16:23, 11 April 2007 (UTC)

Amazing! Thanks for the research & source, Anilocra! --Kfor 15:36, 13 May 2007 (UTC)

Shrimp

The article currently says, "Midwater trawling catches pelagic fish such as anchovies, shrimp, tuna and mackerel, whereas bottom trawling targets both bottom living fish (groundfish) and semi-pelagic fish such as cod, squid, halibut and rockfish."

It caught my attention because shrimp aren't fish. But as I looked around to see the best way to fix, I learned some stuff: The shrimp article says "Most adult shrimp are benthic animals living primarily on the sea floor", and one of the sources says "Otter trawling is, by far, the most common fishing method for industrial shrimp fisheries."[1]

So my question is, are there commercial fisheries of both benthic and pelagic shrimp? I'm going to just put them in the bottom-trawling list, but I don't actually know. --Dan Wylie-Sears 2 (talk) 01:27, 27 August 2009 (UTC)

Most adult shrimp species live on the sea floor, but there are still significant populations of pelagic species, many of which are caught commercially using midwater trawls. In biology, shrimp are not classified as fish. However, in commercial fishing, the term "fish" is used in a more collective way, and extends to shellfish, crayfish, sea urchins, and basically anything that commercial fishermen "fish" for. Likewise, the term shrimp fishery is used. Hope this answers your question. --Geronimo20 (talk) 03:10, 27 August 2009 (UTC)

Current UN eval?

There's an Avazz campaign currently going on against bottom trawling: http://www.avaaz.org/en/stop_ocean_clear_cutting/?rc=fb&pv=40 - which states that "In two days, UN policy-makers are meeting to review the impacts of this deadly practice" (which would make it a Sep 17, 2011 meeting). However, no link was provided to more information about which UN policy-makers, or what they would evaluate. Anyone know more? --Alvestrand (talk) 06:22, 15 September 2011 (UTC)

There is this notification and background stories here and here. --Epipelagic (talk) 06:53, 15 September 2011 (UTC)

wondyrchoum or wondyrchoun?

"How trawls work" section

We've observed how fish respond to trawls by video attached to the trawls or the lines to the trawls. The idea that there are divers seems very wrong, hard to prove a negative, but diving around a quicly moving high tension line does not seem like a good idea. That said, I have video of fish swimming in front of trawls - but no indication that they're attracted to the noise or sediment cloud made by the trawl. Since there's no citations citing the statement that says otherwise, I've deleted that section. If citations can be provided, then I'm happy to learn and discuss.
