Raceway (aquaculture)

A raceway, also known as a flow-through system, is an artificial channel used in aquaculture to culture aquatic organisms. Raceway systems are among the earliest methods used for inland aquaculture. A raceway usually consists of rectangular basins or canals constructed of concrete and equipped with an inlet and outlet. A continuous water flow-through is maintained to provide the required level of water quality, which allows animals to be cultured at higher densities within the raceway.

Freshwater species such as trout, catfish and tilapia are commonly cultured in raceways. Raceways are also used for some marine species which need a constant water flow, such as juvenile salmon, brackish water sea bass and sea bream and marine invertebrates such as abalone.

Site selection

The most important factor to consider when selecting a site for a raceway farm is the water supply. Water sources for raceway aquaculture operations are usually streams, springs, reservoirs or deep wells. Trout do best in spring water because it keeps a constant temperature, while catfish need a strong flow, about 80 litres per second for every 0.4 hectares of raceway. A backup water supply should be positioned so, if the water supply or pump fails, it can flow by gravity into the start of the raceway.

RaceTrac

RaceTrac Petroleum, Inc., is a corporation that operates a chain of gasoline stations and convenience stores across the Southern United States. The firm is Georgia’s third largest private company, with sales of $9.1 billion in 2013.

History

The company was founded by Carl Bolch Sr. in 1934 in St. Louis, Missouri, with his first stores operating under the name Carl Bolch Trackside Stations. In 1959, Bolch relocated and acquired the Oil Well Company of Opp, Alabama, which consisted of numerous independent outlets across rural Alabama.

His son, Carl Bolch Jr., who succeeded his father as chief executive, joined the company in Montgomery, Alabama in 1967. After pioneering the concept of self-service gasoline in Alabama, Florida, and Georgia, the company relocated its headquarters in 1976 to Atlanta, Georgia, and adopted the brand “RaceTrac” for its company-operated stations. RaceWay stations, operated by contractors, continue as a part of RaceTrac Petroleum.

In the 1990s RaceTrac operated as a cash-only business, but it now accepts credit cards, debit cards and fleet cards.
