A 48 pound triploid rainbow trout was caught in Canada's Lake Diefenbaker. The fish was one of 500,000 that were accidentally released from fish pens 9 years ago.
Triploids are genetically altered to have three sets of chromosomes, making them sterile and channeling energies normally spent reproducing towards growth. They get very large, very quickly compared to normal rainbow trout.
The question is... should these "trips" be considered rainbows in regards to the record?
