Here’s some pros and cons I’ve learned over the years.
• fast growing but on the top end reach no larger size than the copper nose
• very aggressive fish. This can make them a favorite for the kids and the fly anglers that might use that pond
• low reproduction…this is both good and bad depending on your objectives. Its bad if you want to also raise predators such as LMB. Its good in that the hybrid offspring are most often inferior to the original parent and less numbers generally = more food for the others.
• doesn’t grow as fast but reaches top end sizes that equal or often exceed the hybrids
• high reproduction makes it ideal for bass ponds and growing big bass
• native species to Florida and will reproduce true to genetics.
So, it depends on your objectives for the pond. In general, I prefer the hybrids in small ponds, i.e. around 1/4 acre and prefer the copper nose in larger ponds and any pond in which one of the target fish is the LMB.
