Well, i have one that you can make as soon as you get the golden bug net, and flower boots, you may need a staff of regrowth, but you can always buy seeds of normal grass from the dryad.
You make line of dirt and mud, the size is up to you, you need at least 1 jungle grass seed and flower boots to make the grass grow and cut it, getting more, once you place all, put 3 blocks above another layer of mud for mushroom.(you dont need the mushroom part but you need an extra layer to stop jungle trees from growing)
Now, if you want to or have teleporters, you can make ANOTHER layer of mushroom above the firs one to stop giant mushrooms from growing and have more, the problem would be to get the mushrooms you destroy, so, you place actuators on this layer, and with the same wire you put teleporters at each side of the bridge, this way everytime you go on the teleporters, you actuate the blocks of the higher mushroom layer(giant mushrooms grow there too, give me some time to show you a picture of my farm)
And you just run from teleporter to teleporter over and over using the golden bug net (the power of the golden bug net is that it can break grass without making damage, so you can pick up bait).
So there it is, from that farm you can get worms, grasshoppers (this 2 can also be golden), jungle grass seeds, a bait critter of the mushroom biome (i dont remember the name) and all 3 bugs of the jungle biome(bait, up to 40%, but rare, the more common is 15%)
If you feel like its too much work, or you are just starting with fishing, you can focus on pre-hm rewards by making new small worlds to do quest faster and on the way, collect worms by breaking rocks.
