Docg, I'll let the biologists answer your question, but I don't know of any reason why not since there has been anecdotal reports of rare reproduction of HSB.

There is a ton of HSB info in the archiives for anyone intersted in HSB:

Hybrid Striped Bass History
The history of Hybrid Striped Bass is very interesting to me, and I wanted to share a few paragraphs from the book listed below for those that may be interested, which in turn necessitates a review of the Striped Bass history in North America.

The following review is based on historical references from:

CULTURE AND PROPAGATION OF STRIPED BASS AND ITS HYBRIDS
Edited by
Reginal M. Harrell
Jerome Howard Kirby
R. Vernon Minton
American Fisheries Society

Chapter 11, page 159
Hybridization, Genetic manipulation, and Gene Pool Conservation of striped Bass

“R.E. Stevens produced the first hybrids between female striped bass and male white bass (SBxWB) in South Carolina in 1965 (Bishop 1968). It has since been demonstrated the striped bass hybrids show heterosis (hybrid vigor), expressed in improved survival, superior early growth rates, greater disease resistance, and increased general hardiness………..

As a result, this hybrid has been artificially propagated and widely stocked in freshwater impoundments for control of shad (Dorosoma spp.) and as a food and sport fish. More recently, the reciprocal of the original cross, female white bass x male striped bass (WBxSB) has been used similarly, and its popularity with management biologists and commercial aquaculturists has increased dramatically over the past few years.

Chapter 1, page 1
History and Overview of Striped Bass Culture and Management

Striped Bass have long been utilized as food, and more recently as a superb sport fish and commercially cultured product. The Massachusetts Bay Colony passed the first legislation in Colonial America to protect a fish species in 1639, when the use of striped bass as fertilizer was prohibited. A tax was levied on the striped bass fishery in 1670 that partially funded the establishment of the first public schools in the new World (Setzler et al. 1980). Antropogenic effects on this species in terms of excessive harvest, destruction of habitat, and pollution have been discussed in literature for more than 100 years Worth 1884; Raney et al. 1952; Mansueti 1962; Coutant 1985a; Goodyear 1985; Price et al. 1985). In recent years antropogenic influences have likely been responsible for dramatic declines in several of the largest coastal populations, most notably Chesapeake Bay and Albermarle Sound (Mehrle et al. 1982)

Striped Bass have been considered desirable for transfer to other areas since they were first successfully introduced to the Pacific coast. In 1879 and 1881, 435 yearling fish were seined from the Navesink and Shrewbury Rivers in New Jersey, transported across the country by train, and released in San Francisco Bay. Within 10 years, an important fishery had developed in central California (Rainey et al. 1952). this population subsequently expanded from southern California to the Columbia River in Oregon.……………..

Inland striped bass programs grew rapidly following the development of culture methodology and facilities, and seven striped bass fisheries had been established in impoundments by 1970, and 23 by 1973 (Bailey 1975). By 1981, striped bass fisheries were established in 100 lakes and reservoirs with a total area slightly greater than 2.4 million acres, while hybrid bass fisheries were present in 179 impoundments (Axon and Whitehurst 1985). Inland striped bass and hybrid programs increased from two established fisheries, which totaled 210,000 acres in the mid-1950s, to 279 lakes (3,953,600 acres) in 1981. Crude estimates indicated these fisheries were yielding annual recreational harvests of over 5.5 million pounds of striped bass and hybrids by 1981.”

HSB are fertile and capable of back crossing with either parent species and even themselves. So yes, male HSB do produce milt. Actual survival of young is rare though as striped bass eggs have the buoyancy of water and are not sticky, while white bass eggs are heavier than water and are sticky. HSB eggs are a cross between the two which isn't a good combination, meaning they generally sink to the bottom, stick to it and get covered in silt. This leads to the death of the embryo inside.

Each stock of striped bass from each river has distinct genetics. They have adapted to the river they spawn in so their eggs stay moving in the current and do not settle and die in the bottom silt. Many anadromous species are like this and are genetically adapted to the specific river they come back to spawn in.

HSB are illegal to stock by private individuals in Virginia because of a fear they may escape the pond they were stocked in, head down river to the Chesapeake Bay and then possibly spawn with native pure striped bass and dilute the genetics. There is evidence HSB can escape ponds and go out to the ocean, as a number of them have been caught in tidal estuaries in brackish waters that connect to full salinity ocean water. In laboratory tests, HSB can survive full salinity ocean water.

Here you go on hybrids and fertility.

Ewest -- thanks ever so much for pointing me back to this thread. It's been a little hectic lately (i.e., pheasant season and guests). :-) I honestly have little background in genetics, and so am learning here, rather than being able to contribute. As Bruce said, I might be able to track down a little background on this sunfish chromosome number from one of our famous fish geneticists. No promises, though!

I am uncertain about some of the other hybrids mentioned. For example, we know that saugeyes can produce an F2 generation, and can also backcross with both parental species. However, I don't think we know if that's true for both crosses (e.g., male sauger or female sauger used). Similarly, I've always believed that HSB simply have a functional sterility (eggs are too heavy to act like striped bass egss, and too light and not sufficiently sticky to act like white bass eggs). However, they can backcross with the parent species. Again, I wonder if we know if that is true for both "directions" of crosses.

This long-hair stuff is good.

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.
