Male OR Female Brown Trout?

medium to small browns are hard to determine if male or female.

Lets hear your best educated guess on gender of these four and why?

  1. top left is a female obviously because of the snub snout, few small spots, and sloping head-to-back, right top and bottom are both males due to the longer snouts, many large spots, and a flatter head-to-back arch. The bottom left is a difficult one but my guess is it is an adolescent male in a slow moving stream because it has many large spots on back and the head starts to curve upwards toward the end of the snout. I think it has the genetics of a true monster.
