<human>:  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?
<bot>: How many fishes did Will catch? ** Will caught 16+10= <<16+10=26>>26 fishes
How many trout did Henry catch? ** Henry caught 3 trout for each catfish Will caught so since Will caught 16 catfish, Henry caught 16*3 = <<3*16=48>>48 trout
How many trout did Henry return? ** Half of 48 trout is (1/2)*48 = 24
How many trout did Henry return? ** Henry returned 24 trout leaving him with 48-24 = <<48-24=24>>24 trout
How many fishes do they have altogether now? ** They now have a total of 26+24 = <<26+24=50>>50 fishes
