Fish Ferts?

First time grower. My question is has anyone made fish ferts? We are big on fishing here, and have "spare parts" after cleaning and eating the fish. I have done some research on the Alaska fish one, with very mixed results. Tonight he blended up the fish and added it to water in a five gallon bucket with a lid. Plans to leave it for two weeks and use it.

If you have done this, how did it work out? Is this too risky?? We plan to add a small amount to water at watering, but, any pre warning would be nice!!:thumbsup::thumbsup:

look into composting. You can compost your fish by-products and have some excellent plant food.
