Can someone tell me weather it is possible to feed one-self during a
high sea cruising trip on a 36' sailing boat just by fishing? I just
dream to buy a boat and cruise around the world, but have zero
experience so far.

You might find it useful to browse the 'Cruiser's Handbook of Fishing' by
Scott
Bannerot & Wendy Bannerot in a bookstore or library.

Steven Callahan's book 'Adrift: Seventy-six days lost at sea' describes his
experience of surviving on fish caught at sea while drifting in a life raft.

Some self-reliant cruisers also trail plankton nets. Whether eating the
catch of a plankton net is advisable or safe or palatable is beyond me.
