You got me there Nigel, regarding the wild Trout in the rivers and streams of Kenya. The names come to mind like, 'Underugu, Chania, all mountain fed streams and all different to fish with Browns and Rainbows and Char. The Chania can be fished at over 10,000 ft and has a waterfall of three steps at over 375ft drop. The pool at the bottom was always productive as it was a head water for the lower half of the river.
Now that fish, the Char was a beauty to fish as it really attacks a fly trolled slowly through the water. I will give away my secret fly as it is a Maribou Muddler that simulates a black Crayfish as it is pulled and released to flare out.
Limited to 6 fish a day on a river so catch six and move over the adjoining hill and fish the next river. The Nile Perch were caught in Lake Rudolf and we caught 22 fish in 2.5 hrs. and the total weight was 1220lb. the biggest, mine was 167lb and I weighed the same as the fish. Catch a small Perch and bigger one will follow and bite it's body off and leave you with the head. A weekends fishing for £50 including the flight and all found for two!
Guinea fowl abound by the thousands and make good eating, Two or three different types like the Helmeted and Vulturine. One will feed 4 people, cooked in a pressure cooker with onion and potato, all white meat.
Regarding worm, all game in Africa is infested with round worm and a gut shot bird you do not eat. Even Mackeral have worm cysts inside the body cavity. Nematodes also abound on fish usually around the head parts. Game animals also get Measles so you look at the liver and if it has white spots leave it.
