Sex Change not supported by source

The passage "Cultivators use hormones, such as testosterone, to reverse the sex of newly spawned females" isn't supported by the source at all. While the passage directly before and after this one are actually on the source, this one is completely absent from the linked article. I think it should be removed.

Link of questionable merit

I tagged the reference to how healthy tilapia is as unreliable--the cited reference makes statements are are completely contradictory to many other online resources (eg http://news.health.com/2008/07/11/popular-tilapia-heart/). Glennklockwood (talk) 22:21, 27 May 2010 (UTC)

I was under the impression that Tilapia were originally herbivorous and have merely adapted their diets to allow for insects and debris. This fact would seem to be a significant reason why Tilapia are less resource intensive and therefore a more sustainable source of protein. Schear (talk) 22:20, 13 July 2008 (UTC)

At least one other link is bogus. There is a supposed link to a Wake Forest study that isn't that thing. It is a link to Dr Axe which gives only a general link to a news page from Wake Forest. This is very suspicious.J Civil 15:26, 3 April 2014 (UTC) — Preceding unsigned comment added by Jan civil (talk • contribs)

From DrWeil.com Weekly Newsletter

A Popular, Unhealthy Fish? well it might be since its on the bottom and in dirty water we dont know yet! Farm-raised tilapia is one of the most highly consumed fish in America. Yet it has very low levels of beneficial omega-3 fatty acids and very high levels of potentially detrimental omega-6 fatty acids.

That’s according to new research from Wake Forest University School of Medicine. Tilapia has higher levels of long-chain omega-6 fatty acids than 80-percent-lean hamburger, doughnuts and even pork bacon, says an article in the July, 2008 issue of the Journal of the American Dietetic Association.

Omega-6 fatty acids are pro-inflammatory, and inflammation is known to cause damage to blood vessels, the heart, lung and joint tissues, skin, and the digestive tract.

For their study, the authors obtained fish from several sources, including seafood distributors that supply restaurants and supermarkets, two South American companies, fish farms in several countries, and supermarkets in four states. They found that farmed tilapia contained only modest amounts of omega-3 fatty acids: less than half a gram per 100 grams of fish, similar to flounder and swordfish. Farmed salmon and trout, by contrast, had nearly 3 and 4 grams, respectively. At the same time, the tilapia had much higher amounts of omega-6 acids.

This is important information. Cardiologists are telling their patients to eat more fish, but if those patients are buying and eating farm-raised tilapia, they could clearly do better. As a follow-up to this report, a coalition of more than a dozen doctors pointed out that tilapia should be considered a better choice “than most other meat alternatives,” but my response is, why not eat the best fish of all? So I strongly suggest adding wild-caught Alaskan salmon to your diet to get the benefit of their impressive omega-3 fatty acid content and low contaminant load. It is more expensive than tilapia, but a worthy investment in health that will reap dividends in the future.Vivaldi4Stagioni (talk) 06:13, 7 August 2008 (UTC)

I agree with some of Vivaldi4Stagioni, but the statement "A diet with a high ratio of omega-6 to omega-3 is suspected to cause inflammation, which can be dangerous for those with heart conditions." does not belong in this article. The pro-inflamatory position with regard to Omega-6 is a controversial one, and far too much information has been produced that shows this important fat to be anti-inflamatory. I agree that the poor ratio of Omega 3 to Omega 6 would make this fish a poor choice if this were the only source of food being taken, but that is not the case, even if it is the most widely consumed fish in the US, which I have not seen anything to back up that claim.Rudolph bonaduce (talk) 01:11, 19 March 2009 (UTC)

To clarify, the lack of DHA in farmed tilapia is the result of a corn-heavy diet. Omega-3 fatty acids are not produced by fish, but rather, are accumulated by whatever they eat. Is there any interest in actually including a substantive discussion of fatty acids in tilapia? If so, I'll do the legwork and source some citable commentary. Sangrito (talk) 19:06, 21 March 2010 (UTC)

PUFA update done, with a few new refs. The last sentence from Nutrition (on us farm output) should be updated and moved up to the farming section along with a suitable ref, i noticed. Pouletic (talk) 21:17, 21 December 2011 (UTC)

Clarify yield

"Whole Tilapia fish can be processed into skinless, boneless (PBO) fillets: the yield is from 30 percent to 37 percent, depending on fillet size and final trim."

Does this mean the fillet amounts to 30 percent to 37 percent of the fish's pre-processed weight? It sounds like that, but I'd be glad if someone who knows would clarify. --Preston McConkie ^{(talk • contribs)} 18:59, 24 July 2009 (UTC)

Inflammation clarification needed

"A diet with a high ratio of omega-6 to omega-3 is suspected to cause inflammation."

Inflammation of what? --Preston McConkie ^{(talk • contribs)} 19:05, 24 July 2009 (UTC)

Consumption of Fecal Matter

I've removed the passage describing tilapia as "the worlds [sic] shitmouth" due to a lack of supporting references. Animals, in general, explore the world to a large degree via their mouths and will inevitably consume some undesirable matter. Overstating the case for tilapia in particular isn't helpful -- remember that the next time your dog licks his ass and then licks your face. Sangrito (talk) 18:59, 19 March 2010 (UTC)

Badmouthing even a s**tmouth food source is never going to be be welcomed as long as the human mouths it feeds might otherwise starve. Or pay more... Dratman (talk) 00:14, 9 October 2024 (UTC)

I believe they are rather common in waterways in Hawaii. I can't bring up any sources, however. —Preceding unsigned comment added by 66.91.36.12 (talk) 01:19, 17 May 2011 (UTC)

Health and Safety Concerns about Tilapia Originating in China

Studies show that American grown Tilapia is pretty safe, but 90% of Tilapia consumed in the US is from China where conditions are often very poor, including serious pollution, use of chemicals in fish farm waters that would be outlawed in the U.S., bacteria, etc... Very little imported fish is inspected before reaching the supermarket or restaurant either. Almost no inspectors "stop" the bad fish coming from outside the country.

98.245.172.142 (talk) 01:08, 2 December 2011 (UTC)

How do supermarkets get away with selling tilapia from China if these fish are so unhealthy? Is there actually evidence that it is unhealthy? 68.126.180.147 (talk) 02:38, 31 March 2012 (UTC)

Effect of fish food on nutrition

The same research suggests the nutritional value of farm-raised tilapia may be compromised by the amount of corn included in the feed. The corn contains short-chain omega-6s that contribute to the buildup of these materials in the fish. Widespread publicity encouraging people to eat more fish has seen tilapia being purchased by those with lower incomes who are trying to eat a well-balanced diet.

any evidence for that last stupid sentence? waa waa leftist crap

Nutrition

I am afraid the words, "2.5 million projected by 2010" have been overtaken by Old Father Time. I find it very common for Wikipedia articles to contain items of this sort, ie which either do not specify the date of writing, or use the future tense for items which are soon lost in the past. Perhaps authors could be more alert to these dangers in future! Dawright12 (talk) 10:12, 30 July 2012 (UTC)

Omega 3 and Omega 6

Numerous studies have discounted the link between omega-3 and omega-6 fatty acids and heart disease, suggesting that the cause of the correlations seen in past observational studies were the result of correlation, not causation. This is a huge sort of divergence in the nutrition section, and I wonder if it might be better to just eliminate the whole bit about them given that the value of omega-3s in fighting heart disease has been very strongly called into question, and the idea that omega-6s cause heart disease is pretty much disproven by the controlled studies. Yeah, there is a difference in the amount of them in these fish, but is that really worthy of inclusion, and if so, what is the best way of presenting the information in a way that does not mislead the average reader? As it is, it is a rather confusing section; I added a bit noting that these linkages have since been called into question, but I wonder if it is even worth incorporating the confusion in the first place.

Temperature tolerances?

The article claims at the beginning (with no citation) that tilapia cannot survive" below 70 degrees farenheit. However, multiple sources I've found state otherwise. I don't know if it's appropriate to put links here, but according to most of the sources I've seen tilapia start experiencing slower growth at 70 F and only start dying at 50-60 F or colder; blue tilapia are specifically noted to survive even at 45 F. 114.25.196.56 (talk) 07:55, 7 May 2015 (UTC)

"Fish of the Philippines" category

I noticed that an old edit of the page had categorized the tilapia as a fish of the Philippines and has remained there for many years, despite the fact that tilapia is not endemic to any Asian countries, and instead, different species of tilapia were introduced and grown en masse in countries such as the Philippines. It appears that a similar issue happened with Bangladesh as well at the time and was subsequently removed .

Edit made in Nov 2012: https://en.wikipedia.org/w/index.php?title=Tilapia&diff=prev&oldid=521772127&diffmode=source

Is it the right call to remove this category as it seems to imply the fish is native to the country when it is not? Ganmatthew (talk) 07:23, 2 July 2021 (UTC)
