Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations Evaluating New Pond and New Fish

Jayson says: Firstly as you are seeing from growth rates in your new bass population, siblings from a hatching or stocking have different growth rates if all have/had the same access to the same amount of food. Some are genetic runts and some are the fastest growers (shooters or jumpers); all others are in between. State record fish were at the top of the Shooter category. Genetic aggressiveness and genetic growth are big influencers, both are individually variable and due to individual specificity of the DNA. It is known as natural genetic variability. There is still a lot to learn about this science.

As far as your question about length weight growth ability, IMO this concept might not have been explained well enough for all to fully understand. I will try and get the originator of that concept to come back and more fully explain or simplify the concept. I will email the forum member to help us with explaining or simplifying he concept. IMO it probably has to do again with genetics of the individual fish. Some have the tendency or propensity to be more tubby whereas some body growth trends toward long and lanky even if they both receive the same amount of food. I think individual physiology of the fish determines how the foods deposited and growth is distributed. IMO all are not exactly DNA equal; similar to humans, dogs, birds and fish. Example - why did some die from covid and some did not even realize they had it, minor or no symptoms? I think most of it is in the DNA.
