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

### Instruction:
Will and Henry go fishing in a river. Will catches 16 catfish and 10 eels. Henry challenges himself to catch 3 trout for every catfish Will catches. Due to environmental concerns, Henry decides to return half his catch after meeting his own challenge. How many fishes do they have altogether now?

### Response:
Will caught 16+10 = <<16+10=26>>26 fishes
Henry caught 3 trout for each catfish Will caught so since Will caught 16 catfish, Henry caught 16*3 = <<3*16=48>>48 trout
Half of 48 trout is (1/2)*48 = <<48*(1/2)=24>>24 trout
Henry returned 24 trout leaving him with 48-24 = <<48-24=24>>24 trout
They now have a total of 26+24 = <<26+24=50>>50 fishes
