I dont think there is one.
I don't think that there is a golden fishing rod. yeah you can on ds animal crossing , what you have to do is catch every type of fish on the game
get every fish
To get a golden fishing rod on Animal Crossing you have to catch every kind of fish. Same thing with the net. (You have to catch every kind of bug)
The golden fishing rod extends the fishing line 2x farther then a regular fishing rod.
You can get a golden shovel, fishing rod, ax, and a net.
You have to catch every bug that there is, same for the golden rod, but with fishes
catch every fish once
To get a golden rod on animal crossing, you have to catch every kind of fish once. The day after you have caught all the fish, the Mayor, Tortimer will be waiting outside your house to give it you. The golden rod makes fish see your bate faster.
Dig a hole with your shovel,put the fishing rod in, and then fast-forward time, then you dig up that hole and it should be golden.
To get a golden fishing rod you must catch all 64 fish at least once.
There aren't any silver tools in the game, only normal and golden.
There isn't one, but one only costs 4 or 5 hundred bells at Nook's, and if you talk to the mayor during the fishing tournament without a rod, he'll give you one.
