Sorry, I'm late to this thread, but I'll add my own limited experience. When in the jungle with the Aeta tribespeople, we fish the river upstream of the water treatment plant. Cyanide and bombs are therefore no-nos, but otherwise there are no rules. The flow doesn't suit trapping and I don't have the skill for tickling. Instead, we gather conical water snails on the rocks late in the day. At sundown, just after the mozzies have fed, we go frogging on the banks. Later, we fish for eel with a live frog on a hook on a bamboo pole. We use frogs that are too small to eat. Later, we set up a frog on each line and rig the line like a spring snare to set the hook. The latter has never paid off in my experience and so I'm considering a line of speedhooks.
Bats, chicken, rats and pigs are just too smart for us, so snail, frog and fish/eel soup is our only half-way reliable source of meat.
