>What I meant was - not you, but when proto-humans ate fish - presumably with >primitive tools, how easy and efficient would that have been to acquire and >eat (scales, bones, etc)? Or is this not relevant to you? Very easy in many occurence, tide pools ,drying out lake . Trapes made out of stone or sticks and using the tides, stealing from eagles ( i have done it) and rudimentary tools like a spear . Peoples in the mountain of europe catch trout by hand ( have done it ) And there is easier animals products to catch without tools in waters ( crabs shrimps clams oursin etc... Here in canada in the fall you can gather spent salmons by the truck load just with your hands. A sharp stone ( we have used them apparently for a very very long time ) can skin a fish or a deer as efficiently than a knife ( especially with obsidian) . >Do you find that you digest raw meat well? It is very digestable when the meat is aged . jean-claude
