AFTER purchasing Tilapia today I(inspired by Dennis' salmon snag...) I did a search and found a post where Connie said she would not feed farm raised fish. I'm perfectly happy tossing the fish - I only bought two - but before doing so, why not farm raised fish?

Definitely not enough bias here to throw away the fish.
"The total world aquaculture production contributes to the global fish supply. Aquaculture is one of the fastest growing food sectors, with production increasing from 10 million tonnes in 1990 to 29 million tonnes in 1997 (FAO, 1999). More than 220 species of finfish and shellfish are farmed today.
However, carnivorous farmed fish are fed on high levels of fish meal and fish oil and require a fish biomass input superior to the fish biomass produced. For the ten species of fish most commonly farmed , an average of 1.9kg of wild fish is required for every kilogram of fish raised. Unfortunately, there is an increase in the production trend of carnivorous fish (such as salmon or shrimp), rather than herbivorous or filter feeder fish. Small pelagic fish mainly provide the fish meal and fish oils used for aquaculture feed. Aquaculture's growing needs increase pressures existing on wild fisheries for small pelagic fish, which already suffer from overexploitation and are strained by climate changes ... "
Also, "Many recent studies have noted differences in the nutritional values of farmed and wild fish. Farmed fish tend to have less Omega-3 in their tissues, and in the case of salmon the feed contains dyes that tint the fish's flesh pink. Wild salmon get their rosy pink color from the natural foods they eat in the deep ocean and rivers. Another concern about farmed fish is that they often have higher levels of PCBs and mercury than wild fish. Additionally, critics of farmed fish point to the higher incidence of disease in farmed fish that are forced to live in more confined quarters and at higher population densities than in the wild.
For more information on the benefits of farmed food versus wild food see the following article from TheDietChannel: Fish Safety & Buying Guide: http://www.thedietchannel.com/Fish-Safety-and-Buying-Guide.htm

Best and worst choices if you do decide on farmed fish:
Thank you for all this information. I've read it briefly but will definatley go back and read it slowly and digest it all.
Two things...
PITA will NEVER get me to call wild fish "sea kittens"
AND
The fact that wild fish are being depleated at a higher rate in order to feed farm raised fish, but in less numbers, makes absolutely no sense to me what so ever. Does ANYONE out there remember what common sense looks like?
I'll probably feed the two poor guys already dead in my fridge, but will do more reading and research before purchasing farm raised again.
As always... thank you for the info. Can we clone your brain?

Why not farm raised fish?
