Untitled[edit]

There should be some mention of sportfishing for Silver Carp. Nathan Jones, the host of *Wild Extremes*, has done a show on bow-fishing for this fish. It is the most physical and amazing bow-fishing I've ever seen. http://www.youtube.com/watch?v=ZmzxyexiB1s

Template:Carptracker Mostly my fault, due to inexperience with Wikipedia, but on re-reading this, it is obvious that it could be made less USA-centric. I don't have time at the moment, though.

The German Wikipedia says "Durch ihr fettarmes, wohlschmeckendes Fleisch eignen sich Silberkarpfen als Speisefische." In English: "Because of their low fat meat and pleasant taste, the silver carp is suitable as a table fish." Don't we often hear about food scarcity or unaffordability? Here's one that is or should be for free. 144.136.178.112 (talk) 02:50, 8 April 2011 (UTC)

The English version of the page says "...Certain species of blue-green algae, notably the often toxic Microcystis, can pass through the gut of silver carp unharmed, and pick up nutrients while in the gut. Thus, in some cases, blue-green algae blooms have been exacerbated by silver carp. Also, Microcystis has been shown to produce more toxins in the presence of silver carp. Silver carp, which have natural defenses to their toxins, sometimes can contain enough algal toxins in their systems that they become hazardous to eat." This seems to be saying that this species is unsuitable for human consumption due to the presence of toxic substances secreted by algae in their diet.

Environment and Survivability[edit]

I am wondering at what temperature the silver carp can no longer survive in? If known, one could then predict how far north it might migrate. For example, perhaps it could survive in Lake Michigan, but not at all (or only in parts of) Lake Superior. Dan Aquinas (talk) 21:54, 3 December 2008 (UTC)

Dan - Mandrak and Cudmore's risk assessment indicates that, based on temperatures alone, comparing the native range to North America, that these fish could cover half of Canada. http://www.dfo-mpo.gc.ca/csas/Csas/DocREC/2004/RES2004_103_E.pdf That does not take into account other habitat issues - but temperature is clearly not the limiting factor. These fish are native to Kamchatka, although they are not considered highly abundant there. —Preceding unsigned comment added by Carptracker (talkcontribs) 14:43, 11 December 2008 (UTC)

Fish pictured in photo is probably not a silver carp[edit]

The fish in the photograph in the box accompanying the text of this article on Silver carp may not be a silver carp. The photo is shown enlarged at these two addresses: [1] [2]

Although I am not an expert, the eye of the pictured fish did not seem as low to me as its genus name Hypophthalmichthys implies it should be nor as low as described in other places. Because of this, I went looking for other pictures, and I found many.

The source of our picture is Wikipedia Japan. Here is the starting point of my search: [3]

As you hover the cursor over each picture, you learn where it's from. I chose several that I assume should be authoritative: [4] [5] [6]

The fish in each of these three photos looks considerably different from ours. Not only is the eye much lower on the head (as its name says it should be), but also the tail, which can clearly be seen in two of the three, is much more forked than the one in our picture.

There is a second photo of a silver carp in section 4 "In North America" of our own article, and it, too, looks much more like the three I list above. It is shown enlarged at: [7]

I do not yet know how to remove a picture and upload a different one. I also do not know how to notify all the other Wikipedias, about 30 of them, of this (probable) error, or, for fairness, how to discuss this with the Japanese Wikipedia and with the uploader of our current picture. Further, as I said, I am not an expert, and this is one of those times when expert advice is needed, even in Wikipedia. Wikifan2744 (talk) 05:55, 4 May 2014 (UTC)

I've replaced the disputed image. --Epipelagic (talk) 08:21, 4 May 2014 (UTC)
