Creel, James (2020-04-30)

The number of catfish farms in west Alabama has declined from 250 to 71 over the 2003 to 2020 period. This has been due to a variety of reasons including foreign competition, changing consumer preferences, volatile market ...

Alternative ingredients in practical diets for Pacific white shrimp (Litopenaeus vannamei)

Qiu, Xuan (2017-04-27)

It is a well-known that fish meal supplies will not increase as most fisheries are beyond sustainable limits. If aquaculture and shrimp production in particular is expected to expand, the industry must move away from fish ...

Bioeconomic Analysis of Catfish Produced in In-Pond Raceway Systems

Fantini-Hoag, Leticia (2021-11-30)

This dissertation describes catfish production over four-years using In-Pond Raceways Systems (IPRS). This technology consists of a floating raceway (RW) cage placed into an existing pond, which allows for more control of ...

Comparing Angler Effort and Catch Rate Estimates Across Creel Survey Methods at Three Alabama Reservoirs

Eckelbecker, Robert (2019-12-19)

I compared different creel survey methods at three Alabama reservoirs (Harris, Jordan, and Mitchell) to identify approaches that could improve precision and reduce costs. I was particularly interested in whether boat ...

Comparing Economic Returns of Dissolved Oxygen Management in Commercial Catfish Production

Holland, Leigh Wilson (2016-05-02)

Catfish culture is one of the largest forms of aquaculture in the US. Catfish production systems have been able to achieve production up to almost 12,000 kg ha-1 year-1 (Bott, 2015) since the increase in availability of ...

Comparison of Ictalurid Hybrid Crosses (Ictalurus punctatus x Ictalurus furcatus) in Floating In-Pond Raceway Systems

Stuckey, Ginger (2015-05-11)

With the US catfish industry facing higher feed costs and stiff international competition, producers are beginning to adopt intensive alternatives to traditional pond culture. Among these are split pond systems and in-pond ...
