Watch out fellow males, you too could be recruited for a dastardly experiment. A fish researcher has created egg-laying male bluegills by giving the boys estrogen. Then he uses normal males to fertilize the male-produced eggs. The offspring? So-called "super males" that have two y chromosomes and can be counted on to mate with normal females to produce only male offspring.
Why? Because fish farmers prefer to raise male bluegills--they're twice as big as females and thus more profitable. Tweet

Amazing what some folks will do for a buck.
what are bluegills being farmed for?
bluegill are being farmed for food and as gamefish (to plant in lakes for fishing).
