Invasive species

I have restored information about Channa argus as an invasive species, omitting a sentence that described its impact as "decimating". There are several sources which assert that the snakehead is a threat to native populations:

Introduction of a small number of snakeheads (for example, less than five) into isolated spring habitats could result in extinction of endemic spring-adapted fishes or crustaceans. Introductions of fishes considered to be far less aggressive than snakeheads (that is, guppies, Poecilia reticulata) in such habitats have had major negative impacts (Courtenay and others, 1985). Snakeheads would not have to establish a reproducing population to reduce or eliminate a fish or crustacean species confined to a small section of a stream or isolated spring habitat. A small number of snakeheads introduced, but not established, in a stream or lake would likely have less of an impact. Nevertheless, any snakehead that becomes established in a water body would represent a significant threat and could potentially put any listed amphibian, fish, or crustacean at risk of local extinction.

The above passage is from a USGS publication. Additionally, the "risk potential" table at the bottom of the page assigns the highest risk to every assessment of Channa argus, labeling it an "unacceptable risk" and "organism of major concern". Due to the hardiness of this fish (see temperature tolerances from FishBase) and other factors, the northern snakehead is a highly invasive species.

I came accross this article: http://www.dailymail.co.uk/pages/live/articles/news/news.html?in_article_id=516092&in_page_id=1770 which prompted me to look this fish up on wikipedia. I believe it could be of interest, particularly as it mentions the fact that it may become an invasive species in the UK. The article is a little sensationalist I have to admit.Jarby (talk) 12:56, 19 February 2008 (UTC)[reply]

Myth?

"This unusual respiratory system allows it to live outside of water for
several days, where concern is that it might wriggle its way to other bodies of water or be transported 
by humans."

Isn't that just a myth..? Meaning that time, several days... more like hours?

It is actually truth, i have been speaking to DEC agents over the past few days and they estimate about a six or seven day period so long as the fish is wet or moist while out of water, such as mud, or in a rain storm —Preceding unsigned comment added by 69.115.137.162 (talk) 16:22, 7 August 2008 (UTC)[reply]

Was there any legal action taken for the introduction of this fish into the Crofton Pond. --Paragoalie (talk) 11:52, 4 January 2011 (UTC)[reply]

Obligate air breather

Is it really an obligate air breather? Is that not highly unusual in a fish?

Movies?

"In a well-known incident, several were found in a pond in Crofton, Maryland, in June 2002, which led to major media coverage and two movies."

What movies are those? — Preceding unsigned comment added by 71.235.184.247 (talk) 01:31, 20 February 2019 (UTC)[reply]
