I'm starting a project on researching history and different practices in producing fish fertilizer, with reference mostly to traditional and local productions and strategies worldwide as opposed to big industrial set ups. I want to look at independent research already done in that field, traditional knowledge recorded in reports that may have or may not have become very popular but invaluable nevertheless.
Any sources, links or pointing in a direction would be greatly appreciated.
