Talk:Sea lamprey

Question about the victims

Victims typically die from blood loss or infection.

The article would benefit from answering the question: Out of fish that are attacked by a lamprey, what percentage of them die because of the lamprey? How many of them live a normal-length fish life, just with a lamprey sucking blood out of their side? Tempshill 19:23, 5 April 2007 (UTC)

Sea lamprey control in the Great Lakes

Ok, it seems that not many people know that sea lampreys are food and are actually quite a delicacy in Portugal and Spain. Instead of investing hundreds of thousand of dollars in ways to destroy them, thus wasting money, why not invest this money to find ways of making it a viable export? I mean, we are currently dumping a specially engineered poison in selected areas to cull their numbers. Not only is it not very effective, it is also harming some indigeneous species. As bad as sea lamprey are for other species, adding selective poison to the mix is a rather reckless solution. And the other solutions aren't much use either.

Can someone tell me if something is currently done to transform this problem into an actual business opportunity? Are there so little people who see the sense in this?

The problem is that lamprey meat does not stay like fish does. You're pretty much limited to serving it fresh locally: Express shipments to Europe would probably not be profitable; And people in Canada and the US just don't find the idea of eating lamprey appetising. You might be able to change that over time, like with the taste tests mentioned in the article and stuff, but it's not exactly a science, changing people's palates that is. --216.26.202.245 (talk) 05:01, 3 January 2008 (UTC)

mercury cite?

THis article, http://pubs.nrc-cnrc.gc.ca/cgi-bin/rp/rp2_abst_e?cjfas_f06-012_63_ns_nf_cjfas, mentions that Hg levels in lamprey range from ~80ng/g to ~900ng/g. Based on this page, http://www.nrdc.org/health/effects/mercury/guide.asp, US food staples are typically less than 500 ppb. If we can equate ng/g to ppb, it's clear that some lamprey exceed typical standards. But the abstract says nothing on the distribution, and I can't find another cite online. I'm removing the mercury bit until there's a cite to support it. —Preceding unsigned comment added by 68.124.136.131 (talk) 06:49, 16 October 2007 (UTC)

Taste Test?

Is this actually information that belongs in an encyclopedia? "He said it actually tasted pretty good" doesn't exactly seem professional. 66.41.145.190 (talk) 02:28, 25 September 2008 (UTC)

I've removed that statement as it wasn't included in the source. The main part of the food section was added in one edit (diff). There's no mention of the quote or the person who said it in the source. Cycle~ (talk) 18:14, 20 January 2009 (UTC)

Exterminate

exterminate them now matter how or in 50 years the lakes will be devoid of fish —Preceding unsigned comment added by 74.229.22.19 (talk) 00:41, 15 October 2009 (UTC)

added external link to factsheet

Attacks on Dolphins?

If they sometimes attack humans, maybe they also attack dolphins? Are we data deficient of this, or do they not attack them? Perhaps we are missing this? It would probably be in the first section, though. 71.202.9.196 (talk) 03:40, 2 October 2010 (UTC)

Adding Physiology Section

Hi, I have an assignment to add information on a wiki article to a species of my choice, and I just wanted to inform everyone that I'll be adding a brief Physiology section to the page with information from a couple of papers that I've been researching. Thanks, and here's a shortened bibliography for those interested.

Good stuff; I've edited it a bit to tone down the jargon. Remember, the target audience is not physiologists :) -- Elmidae (talk) 07:47, 29 April 2016 (UTC)

If lampreys could talk

They'd probably applaud the selection of photos we've chosen, where both the lede and the largest image show a pair of sea lampreys getting the better of a hapless trout. But if anyone wants them, we also have closeups such as File:Sea_lamprey_(8740460349).jpg and this one where they look more like typical fish with easily distinguishable eyes and gills. Note that the second picture is not explicitly labeled as a sea lamprey, however. —Soap— 17:29, 16 July 2019 (UTC)
