you can make 2000 sq ft of 3" mesh netting out of the 20x20 tarp. and convert that 3" mesh to 1.5" mesh by weaving in splits of local vegetation. 3" suffices to hold waterfowl. You can weave in more vegetation, converting the 1.5" mesh to 3/4" mesh, so as to make traps for smaller birds. Between small birds, waterfowl, fish, predators, some snared squirrels and boxtrapped rabbits, cambium and tubers, you can maintain your body weight until you can snare or arrow a big critter, preferably a big bear that's fat for the winter.
Since you can make FAR more cordage and netting out of the 20x20 tarp than you can take, the gillnet, rope, paracord are all wasted picks.
I"d take a slingbow, so that I could more easily keep it with me, and have 3 of the arrows be three pc takedown models. I'd want 3 broadheads and 6 judohead blunts. The blunts should alll feature flu flu fletching. I can make baked clay balls for "ammo" for the slingbow, for shots that dont justify the risk of loss of or damage to an arrow.
I'd take the snarewire, as 1050 ft of stainless steel 20 ga wire, cause it's twice as strong as carbon steel wire and camo-dye it while still at home.
If you'll not be on the sea, you have to take the salt block, so you can preserve meat and fish a lot more reliably. It's also helpful for choking down bland or bad tasting food, (like sea gull) and is a great bait, but only if not near the sea. If you'll be on the sea, take a couple of lbs of pemmican instead.
Take the fishing kit as the biggest single hooks allowed. Cut them in half and reforge the ends, so as to have 50 small single hooks. Then use the Crunch and the snare wire to create 16 treblehooks and set them for predators. Every predator is eating some of your food, every day. Get rid of all of them you can and you'll have more food.
