Fish Emulsion DIY experiences

Hello, I love to bowfish for invasive carp in my local water ways.  Fish waste is a big issue.  I spent a couple years doing a "Fish rotation" in my garden.  I would choose a bed to, at the end of the season, bury a the fish carcasses and plant into it the next year. I would move to the next bed the following year. However, all in all, my soil likes it better when I am doing a cover crop rotation through my garden bed system.  I am want to experiment with making fish emulsion with my fish waste. There seem to be two primary methods out there, the saw dust, fish, and molasses method and the sugar and fish method.  For those that have tried either or both of these, what are your thoughts on which worked better and was easiest to manage.

No one?

Hi Ian, I have no experience dealing with fish but find your project interesting.  How much fish are you dealing with? Does it come in a large load or you have small continuous input? How about testing both methods side by side?

Here is the recipe I have stored away.  But haven't used it.  So no idea if it works best.
