The drums lot that targets the 18-27" allows for maximum recruitment and increases growth rates within the slot due to lower competition,which results in more and bigger fish. It may not be intuitive, but it is in practice, supported by the science, and it works.

You originally stated that killing one 40" fish was the same as killing three 28" fish. Starting from now and going forward assuming all fish reach the same age (say 20 years) the eggs produced by the three fish will far exceed the eggs produced by the one. The smaller fish are going to grow and produce more eggs and the larger fish going to die off first.

A slot limit may be the answer, or maybe not. My only point was that mathematically you are likely get a greater return over time with the three smaller fish.
