There were 20 fishermen in the lake who had cast their net to catch fish. If they caught 10000 fish in total, and 19 of them caught 400 fish each with their own net, calculate the number of fish the twentieth fisherman caught. Let's think step by step and output the final answer after "####".

The 19 fishermen who caught 400 fish each caught 400*19 = <<400*19=7600>>7600 fish.
If they caught a total of 10000 fish, the twentieth fisherman caught 10000-7600 = <<10000-7600=2400>>2400 fish alone.
#### 2400
