Below is an instruction that describes a task. Write a response that appropriately completes the request in French. Please answer in French.

### Instruction:
 James catches 3 kinds of fish. He catches 200 pounds of trout, 50% more pounds of salmon, and twice as much Tuna. How many pounds of fish did he catch?


### Response:
 Il a attrapé 200 * 0,55 = 100 livres de saumon de plus que de truite.
Il a donc attrapé 200 + 100 = <<200+100=300>>300 livres de saumon.
Pour la truite et le saumon, il a attrapé 200 + 300 = <<200+300=500>>500 livres.
Il a attrapé 2 * 300 = <<2*300=600>>600 livres de thon.
Au total, il a attrapé 500 + 600 = <<500+600=1100>>1100 livres de poisson.
