Gentlemen, the point is being missed. This is not about pollution runoff. It's about freshwater vs saltwater and the ratios between the 2. The more of 1, the less fry survival there is due to less food due to the turbidity of the water.
I just don't have the facts the way the speaker presented them but I do know that there was no mention of fertilizer, pollution or their effects on the fish spawn or survival.
I now wish I had access to the good Doctors notes and PowerPoint presentation.
