Good kit.. i agree with most of the posts to help you improve it a little.. Food, Shelter.. I would add a hand towel at a minimum or a camp towel.. and a roll of garbage bags.. can be used for water proofing or emergency ponchos.. or gathering water

the fishing kit might be a littl much. and slim down the containers.. as far as fishing line have some 8lb test or so and then a roll of some heavy stuff, you can use it off the rod and the lighter stuff at the end as to not waste you lighter line.. swivels and split shot sinkers are great.. a good variety of hooks.. but maybe some leaders in case you run into some bigger fish.. and a long leader can also be used as a snare. throw some fake worms and jigs in there .. you never know what they are gonna bite on;

like the others your fire starting might be overkill.. fire is important but you have more than enough there..
consider a camp axe or hatchet at the least.. even my daughers have a collapsable shovel and hatchet.. you can ues it to pound your stainless steele nails that your gonna add too..

the knives look good but do consider some variety.. i assume you probably have a small pocket knife on u but wouldnt hurt to slip on in the bag..cold steele makes a survival knife that can be easily fashioned into a spear.. so consider that
a couple of MRE's and bottles of water to start u off too.. and dont be scared to throw some hard candy for a treat for u or the kids..
clothing.. i agree you should have some socks at least.. underwear and t-shirts.. all easily rinsed with bar soap in a stream to freshen them up. but throw a pair of mid weight gloves with a skull(or stocking) cap at the minimum.\\

keep in mind when your assembeling it that it might be the only thing you can grab or have room for.. yes ideally we would like to walk around the house and take everything we need.. but the B.O.B needs to be the thing you will rely on..
Also consider getting a small .22 pistol to put in there.. i assume you have other firearms but the bug out bag should have something in it so its complete..
just remeber you will be hauling it on your back so gather it all together again.. and see what you might be able to trim back on
if you have a family each person should have a pack.. you might be able to carry more and extra stuff.. but be sure there kits are complete too.. have some cards and games too..

two way radioes or scanner to hear whats going on locally plus a radio to keep you up to date /with batteries of course/
something blaze orange as well.. there has been many times i was out hunting and had hung an orange opject on a tree or something to get the attention of someone walking near my area and it works.. they always stop and look for me... then back out.. so look for some blaze orange on sale now that hunting is over.. you can pick it up cheap.. you just need a shrit or hat .. it really get the addtention of someone in the wooods.. they also make rolls of marking tape that is brightly colored that you could use to mark your trail.

Not dinging your kit.. it looks great.. just put things in ziplock bags and make a few adjustments..
