Just curious, about what percent of the eggs actually hatch in an aquaculture setting ( I am assuming that in a naturaly setting it will be lower).
Your lucky I dont live close to you, cus I would be over all the time picking your brain... Thanks for always posting cool information...
I notice in the picture that the yellow is not very bright. Is it the picture or is that just the color of farm raised fish?
Very interesting! Have you been able to find out what triggers the spawn? moon? sun? water temp? Seams like every body of water has it own spawn time. (march, april or may) And have they always spawned on a certin date?
How does water depth play a role? That great pic you have of the spawn looks shallow but was wondering if the spawn in deeper waters too.
Also I heard the Perch eggs are toxic to other fish. Is that true?
Thank you very much for the info. I look forward to any other tid-bits you want to share! Mark
