PAS specializes in the production of channel catfish, striped bass, largemouth bass, and white sturgeon for distribution to a variety of markets both domestically and abroad. This includes stocks for other fish farms, fish for the live fish markets, fingerlings and catchable size fish for recreational fishing lakes, and newly hatched fish for a growing market to fish farms in other countries.
The bluegill is a deep, slab-sided sunfish with a rather small mouth. Males in breeding colors often have a deep red, almost dark brown breast. The side usually display vertical bars, but these are more prominent in smaller fish. The gill covers and chin are bright blue, giving the bluegill its name.

Growth of bluegill varies widely with population density. High population density retards growth while the opposite occurs with low density. Bluegill will reach 1 to 2 inches in length on the average in their first year of life. Bluegills mature during the second year under suitable conditions, but slower growth will delay maturity to the third year. Bluegill attain a length of up to 12 inches and weigh up to 2 pounds, but most bluegill caught by anglers seldom exceed 8 inches. The very popular and beautiful bluegill is also known as a sunperch, blue sunfish, copperbelly, copperhead, coppernose bream, redbreasted sunfish, yellowbelly, bluemouth sunfish, baldface, plumb granny, pumpkinseed, pond perch.

Channel catfish have been cultured by the owner of P.A.S. for over 22 years. Professional Aquaculture services has developed a strain of channel catfish that demonstrates rapid growth and disease resistance. The stocks have been found clear of all major pathogens including, Channel catfish virus and E.S.C. Fish from the Chico strain are used throughout the world to establish disease free brood stock populations. These fish are also used as control fish for viral and bacterial work by researchers.

Fathead minnows are the ideal forage fish, because adult fathead minnows are still small enough to be eaten by any predator fish. Fathead minnows are often stocked in new or less established ponds and lakes as the primary forage fish, before or simultaneously stocking the waters with a typical largemouth bass, bluegill or channel catfish combination. Although any of these fish; bass, bluegill or catfish does well on its own, minnow stocking helps get the fish population off to a good, strong start, providing any new or growing predator fish with an immediate and plentiful food source. For appropriate minnow stocking rates, see our recommended stocking density. (in the orange)

For the first time in California, a domestic brood stock of striped bass (Morone saxatilis) has spawned and resulted in the production of domestic striped bass fingerlings. Tony Vaught, owner of Professional Aquaculture Service reported that in 1995 and 1996, the domestic brood stock held at his site since 1989 spawned and resulted in the production of the first domestic crop of striped bass fingerlings in the state. The fish are marketed to other growers and will be grown to brood stock to continue the line. At the production facility, located in Chico California, Mr. Vaught developed a viable brood stock by the manipulation of temperature, and diet. The fish in some cases spawned without the use of hormone injection. He plans to refine the process to reduce the time required to bring the brood stock to maturity and to move towards year round production of larvae. P.A.S. has continued to improve the genetic fitness of its stocks to perform as a new production fish for pond and tank culture. In 2003 fish were stocked in open ponds and brought to market size at densities surpassing that of channel catfish. Striped bass can be raised in fresh, brackish or salt water. The fish command a higher price than many fresh water fish offered in urban live fish markets.

P.A.S. provides striped bass to a variety of markets. These include fish for stocking of fresh water lakes in California, the production of fingerlings as well as an export market to other growers of striped bass outside the United States. Mr. Vaught has committed his firm to the production of a domestic striped bass for aquaculture.

Larva, fingerling and market size fish are available on a seasonal basis. Orders must be places for larva and fingerlings by March of each year to secure a place in the production cycle.

White sturgeon have been an integral part of fisheries research and development at PAS. Mr. Vaught was involved in the development of the first domestic white sturgeon brood stock. Together with researchers for the University of California at Davis, Mr. Vaught and other growers cooperated to move the culture of white sturgeon from an R and D species to full production in less than 8 years. PAS now provides fingerling sturgeon to other growers and provides fish to recreational lakes.

Largemouth bass has been cultured for private and public lake stocking. This has been done in extensive ponds. PAS is moving into the intensive cultivation of this fish for sale to other fish farms and to raise for the live urban fish market. Research has been ongoing in the formulation of diet and feeding practices for many years. We now feel that the time is right to put this information to work.

Mosquito fish are commonly known for their use as an easy mosquito combatant. They are live-bearing and produce 3-4 broods per year. The food of mosquito fish consists chiefly of small animals such as crustaceans and insects, but diatoms and algae are also eaten. The species feeds at the surface and invades water only a few inches deep, thereby permitting the fish to prey effectively on mosquito wrigglers. The life span is from about six to fifteen months. This fish has been stocked throughout the world for mosquito control, particularly to combat malaria, and its appetite for mosquito larvae is well known.

The blackfish is a large, dark minnow with an upturned mouth. It is nearlyround in cross section and has a conically-shaped head. It has small, fine scales. It grows to a length of two feet. The pharyngeal teeth are very long, and nearly straight.

It is found in the large natural lakes of central California, such as Clear Lake, and the lower slough-like reaches of the Sacramento and San Joaquin rivers and their associated drainages. It does not move into the swifter portions of the tributaries or into the foothill reaches of the rivers.

The blackfish reached its greatest abundance in the marshy, overflow areas, like Tulare Lake. It has been introduced into southern California. Like the carp, it spawns in shallows and is a prolific egg producer. A 17-inch female contained an estimated 350,000 eggs. The growth rate is rapid. In Clear Lake, blackfish range from 2.5 to 6.5 inches in length at the end of their first growing season. It feeds on plankton and bottom materials. The blackfish is of minor commercial importance, with over 100,000 pounds harvested in 1962: Fish are trucked alive to fish markets in Oriental districts, where the buyers select fish and carry them home alive. The young of this species are eaten by game fishes.
