hey...thats an idea if you are in a reletivly small pond and theres fish swimming in it you could dump in the potassium parmangenate and hay plenty of food?? here is a list of all of the ways I have in my pack to light a fire

1 frensel lens...easy on a sunny day (5)
2 bic lighter (1)
3 strike anywere matches AND lifeboat matches (2)
4 magnesium fire starting block(6)
5 ferrocerium rod(fire steel) (3)
6 fire piston (4)
7 flint and steel(7)
8 fire plow(don;t bring it but can make one(9)
9 potassium permengenate and glycerin(8)


Tinder

Ranger rubber bands
charcloth
jute twine (tons of it)
manilla rope (for the nest)
petrolium jelly coated cotton balls
maya wood


all of this is carried in my kit (usually) and im only 13... I keep a bag that can be put on my belt with all of this in it... the bag can actually be burned also. I am allowed to practice my fire skills in my garage with the door open and on the concrete so I feel like I can use all of these things well. If I had to start a fire and I could choose one of the above things from each list I would probably choose my fire steel( I love that thing) and just twine (a whole roll of it could start thousands of fires (i usually use just 1-3 inches of it per fire..)
