Just like at every hatchery, making for genetic inbreds, it works exactly the same in any fish farm or hatchery. Many Fishermen have the exact same issues, the gene pool proves it. AIFMA APPROVED! Just change the name to BBFA. 

Call em "Wild Caught" at ASMI, after being jacked off in a plastic bucket. These hatchery systems are disasters, always have been, always will be.

Darwin figure it out long ago. Artificial Selection. That's what happens to your farm or hatchery fish, jacked off in plastic.
