red tilapiaThis article is aimed specifically at the Tilapia that are either de-sexed using drugs or chemicals, or those using the so-called Supermale. This is not aimed at hybrids of pure strain O.Aurea, O.Nilotica, O.Mossambicus, or O. Hornorum. If you are raising hybrids to sell commercially, that’s your lookout and up to your conscience, but if you’re raising them to feed to your own family, I’d do some research on them if I were you!

First off, I wouldn’t want to put something in my mouth, nevertheless my stomach that might have been a female, but was chemically altered to make it a male. That kind of genetic alteration just leads to problems, diseases, malformations, or chemical imbalances 20 or 30 years down the road. That’s why we’ve got illnesses like Alzheimers (aluminum cooking utensils), GMO foods (cancers, allergies), Brucellosis (Mad Cow disease) now proven to cause brain disease in humans …… etc., etc., etc. ad nauseum. I have found some research on the chemicals used (Synthetic Steroids, Androgens, such as MT, hormones, mixed with alcohol, fish oil (remember mad cow disease?), or Vegetable oil, but how long do they stay in the fish’s body, and can they eventually build up in the body of the humans that eat them?

Over 95% of all Tilapia today are raised for commercial food production and are usually either genetically or chemically altered to produce the faster-growing males, PLUS they are normally fed diets that often contain hormones and dangerous chemicals.

And how do they reverse the sex chemically? Here’s a couple of quotes:

The most commonly used synthetic estrogens for sex reversal are the non-steroidal estrogens, ethynylestradiol (EE) and diethylstibestrol (DES). DES is the more potent and once was used as a growth promotant in livestock until banned by the US Food and Drug Administration in 1979. Both are carcinogens.

Let’s see, the FDA bans these synthetic hormones as a growth promotant in livestock in 1979 because they’re carcinogenic, but now the FDA allows them as a growth promotant for the fish we’re going to eat ….. how does that work?

Then, of course, there’s the fry bath where the fry are dipped once or twice in testosterone, mestanalone, or estrogen for a period so that they can reverse the sex of the fry…..

Bath treatments with estrogens have not successfully feminized tilapia. Rosenstein and Hulata (1993) treated O. mossambicus with 17alpha-methyltestosterone over a range of concentrations and durations with no effect on the sex ratios.

Toxicity is an issue in estrogen treatments. Eckstein and Spira (1965) reported high mortality of O. aureus fry when given stilbestrol diphosphate baths at 400-1000: g/l.

Of course, the food suppliers want to help out the growers, so they provide the steroid and hormone-treated feeds and lots of good advice ……
Since male Tilapia grow faster than females, it is advisable to use an all-male population. Many Tilapia growers purchase all male sex-reversed Tilapia from fingerling producers who specialize in sex-reversal. – Purina Mills

The Supermale Hybrid

YY-Production-Females-HRI found some research on this that was very interesting. The problem with the super male is that the offspring, which do grow rapidly, are a very inferior fish and successive generations produce poorer and poorer quality fish and breeding colonies must be constantly replaced. One thing you will rarely be told about offspring from these “Super Males” is that to achieve the rapid growth, the large-scale food producers must feed diets supplemented with hormones such as testosterone and/or cancer-causing chemicals that we end up eating! A Cuban research paper has shown what is used to produce these Supermales ……Philippines-YY-Hatchery-complex

From the book, Genetically engineered food by Knut Heller:

Now I don’t know about you, but I’m really not into the idea of having Human Cancer virus’ and Monkey Cancer virus’ put into my food. To clean this witches brew, they dip it into an E.Coli bath“ I’m confused, I thought E.Coli wasn’t a good thing!

What are these chemicals they are putting into the fish? Read on:

Human Cytomegalovirus (from the Greek cyto-, “cell”, and -megalo-, “large”) is a herpes viral genus of the Herpes viruses group: in humans, it is commonly known as HCMV or Human Herpes virus 5 (HHV-5). CMV belongs to the Betaherpesvirinae subfamily of Herpesviridae, which also includes Roseolovirus. Other herpes viruses fall into the subfamilies of Alphaherpesvirinae (including HSV 1 and 2 and varicella) or Gammaherpesvirinae (including Epstein-Barr virus). All herpes viruses share a characteristic ability to remain latent within the body over long periods.

HCMV infections are frequently associated with salivary glands, though they may be found throughout the body. HCMV infection can also be life-threatening for patients who are immunocompromised (e.g. patients with HIV, organ transplant Other CMV viruses are found in several mammal species, but species isolated from animals differ from HCMV in terms of genomic structure and have not been reported to cause human disease. recipients, or neonates).

HCMV is found throughout all geographic locations and socioeconomic groups and infects between 50% and 80% of adults in the United States (40% worldwide) as indicated by the presence of antibodies in much of the general population. Seroprevalence is age-dependent: 58.9% of individuals aged 6 and older are infected with CMV while 90.8% of individuals aged 80 and older are positive for HCMV. HCMV is also the virus most frequently transmitted to a developing fetus. HCMV infection is more widespread in developing countries and in communities with lower socioeconomic status and represents the most significant viral cause of birth defects in industrialized countries. CMV “seems to have a large impact on immune parameters in later life and may contribute to increased morbidity and eventual mortality.”

From the Wikipedia article, Cytomegalovirus –

SV40 is an abbreviation for Simian vacuolating virus 40 or Simian virus 40, a polyomavirus that is found in both monkeys and humans. Like other polyomaviruses, SV40 is a DNA virus that has the potential to cause tumors, but most often persists as a latent infection.

The virus was first identified in 1960 in cultures of rhesus monkey kidney cells that were being used to produce polio vaccine. It was named for the effect it produced on infected green monkey cells, which developed an unusual number of vacuoles. The complete viral genome was sequenced by Walter Fiers and his team at the University of Ghent (Belgium) in 1978. The virus is dormant and is asymptomatic in Rhesus monkeys. The virus has been found in many macaque populations in the wild, where it rarely causes disease. However, in monkeys that are immunodeficient due to, for example, infection with Simian immunodeficiency virusSV40 acts much like the human JC and BK polyomaviruses, producing kidney disease and sometimes a demyelinating disease similar to PML. In other species, particularly hamsters, SV40 causes a variety of tumors, generally sarcomas. In rats, the oncogenic SV40 Large T-antigen was used to establish a brain tumor model for PNETs and medulloblastomas. The molecular mechanisms by which the virus reproduces and alters cell function were previously unknown and research into SV40 vastly increased biologists’ understanding of gene expression and the regulation of cell growth. Claims have been made detailing the controversy surrounding SV40 research. One book by a pair of investigative journalists contains statements indicating that researchers were penalized for reporting the findings of a potential cause and effect relationship between the early polio vaccine, SV40, and cancer. The book further alleges the falsification of research due to financial conflicts of interest.

From the Wikipedia article, SV 40 –

The “Green Monkey Virus”, SV40, was used by Sauk when developing his Polio Vaccine, and it’s been used ever since …. now, most humans in every developed country on the face of the earth have it in their system. It’s no wonder that since Merck, Bayer and the other huge Pharma companies have been given a green light by the FDA to create all of these new “life saving” drugs without proper testing, new drug-resistant diseases and plagues are running rampant ….. e.g. AIDS, Legionnaires Disease, Asian flu, Avian Flu, and now Swine Flu, and most of these are caused by weakened immune systems … thanks to GMO’ed Foods, refined sugars, etc.
