Does anyone know who the authority is when it comes to hybrid stripe bass. Here's is what I would like to know. I have heard that because Hybrids are sterile they will try to spawn with yellow bass/sand bass thus decreasing the number of yellow bass/sand bass in a lake- a really good thing. I know this is done with other animal/insect species to help control an unwanted species. Answers?

This is THE authority when it comes to Hybrid Striped Bass: "Culture and Propogation of Striped Bass and It's Hybrids" Edited by: Reginal M.Harrell James Howard Kerby R. Vernon Minton American Fisheries Society This publication has been very useful to me over the years. I highly recommend it for anyone that has serious interests in Hybrid Striped Bass.

Hybrid striped bass are not sterile. A select few PBoss members have reported spawning success and recruitment of their HSB. I have seen eggs in some of my HSB harvested females. See this link for HSB spawning information. http://www.arkansasstripers.com/hybrid-striped-bass-spawning-habits.htm Verification by Dr.Willis from a previous post on PBoss Forum. Actually masterbasser, it's even worse than the state biologist told you. Hybrid striped bass are "functionally" sterile. The 1:200,000 probably applies to hybrids spawning with hybrids. However, the males of both species commonly run with either striped bass or white bass, and they certainly can produce a back-crossed generation with either. For example, hybrid males running with striped bass females will produce offspring that are 3/4 striper and 1/4 white bass genes. The "functional" sterility comes from the difference in egg types for the two parentals. Striped bass have eggs that are nearly neutral buoyancy, and along the east coast they spawn in rivers that carry the eggs while they develop and hatch. If the eggs settle to the bottom, they typically smother and die in the organic/silt layer on the river bottom. Eggs need some oxygen, which crosses the membrane. White bass have heavy, sticky eggs. In rivers, they spawn on gravel riffles. The sticky, heavy eggs attach to the bottom and the current keeps them clean and oxygenated. Hybrid striped bass eggs are halfway in-between. They are too heavy to float with the striped bass eggs, settle to the bottom, and generally die. They are too light and not sticky enough to stay on the gravel if spawned in a riffle. They wash off, into a pool below, settle on the organic mud that usually has low or no dissolved oxygen, and die.
