in the Tampa bay region there are have many opportunities for locally raised, grass fed beef, start with "My Mother's Garden", an organic grower who has contacts with beef ranchers in the area. She is at the Sarasota Farmers' Market, Saturdays. Also The King Family Farm in Bradenton can suggest many resources for pastured poultry, eggs, pork and beef. they are open, at the farm from Tues. to Sat. 9:00 am to 5:00 pm.
Also if you are pressed for time and cannot catch your own seafood; A.P. Bell, Cortez will sell individual whole Grouper, (Reds, Gags, Blacks and occasionally Yellow Edge), at $4.00-$6.50/lb, "on the bone", One can call and find out what boats are unloading that day, some are day boats, and others are longliners.
I am working on meeting a young couple that makes cheese from their organic dairy herd, will let Florida CH know once I have more info. on this. I have purchased pastured chickens, dressed large fryers, in a town called Gulf City, it is just a crossroad near Ruskin, from a farmer who specializes in naturally raised Heritage Turkeys," Bouirbon Reds", for Thanksgiving;Pate's Farm, Gulf City.
Overall, getting back to alternatives to Tilapia and other "Factory farmed" fish and/or animals if you look and ask there are more and more ways to get really good tasting, Organic and/or naturally raised food with the added benefit of seeing and knowing what you are eating, is raised/grown.Any others care to "share" their finds????
