I'm watching the news the other night and they did a report about the advantages of farm raised fish, particularly cat fish. They said that the feed them mainly corn so that they have a higher nutritional content and it keeps them gfrom bottom feeding. Any body have any thoughts on this? It seems that a higher nutritional content would be a good thing. Are there any canning recipes for fish that aren't straight pickling? I pickled some store bought haring and it's good but I'm ready for something else.
