This document is about Tilapia, which is a generic term used to designate a group of commercially important food fish belonging to the family Cichlidae; the expression is derived from the African native Bechuana word "thiape," meaning fish. Cichlids are classified in the large order Perciformes, and inhabit the fresh and brackish waters of Africa, the Middle East, coastal India, Central and South America. True tilapias, however, are native only to Africa and the Middle East. Although exotic to the United States, populations of tilapia are now established in Arizona, California, Hawaii, Florida, Nevada, North Carolina, and Texas. First published July, 1992.

This document is about Channel catfish (Ictalurus punctatus). Channel catfish belong to the family Ictaluridae, in the large catfish order Siluriformes. The order includes over two thousand species, and most of them inhabit the fresh waters of the tropics. In the United States, the family Ictaluridae is native to the water drainages east of the Rocky Mountains, and contains about forty-three recognized species. Other important commercial species in the family include the blue catfish (I. furcatus), white catfish I. catus), yellow bullhead (I. natalis), brown bullhead (I. nebulosus), black bullhead (I.melas), and the flathead catfish (Pylodictis olivaris). First published in July, 1992.

This publication provides information on common third-party certification programs for aquaculture products, mostly those intended for human consumption. The goal of this document is to increase consumer awareness and understanding of what commonly observed third-party certification labels signify. Includes some discussion of certification programs for ornamentals and baitfish.

The aquaculture industry can use feed attractants to improve the feed intake efficiency of various fish and shellfish species. These attractants can improve fish growth and survival, particularly during the sensitive early-life phases when effective feeding is critical to survival. Thus, there is a need to review the types of attractants and their effectiveness in improving fish growth and survival. In this EDIS publication, we provide background information on how feed attractants work and a list of available feed attractants used by the industry.

The goal of this study was to develop a rapid assessment of microalgal concentration using a turbidity meter to serve commercial shellfish hatcheries for feeding shellfish larvae and broodstock. We used four commonly used algal species, Tetraselmis suecica, Isochrysis galbana, Chaetoceros calcitrans, and Chaetoceros gracilis, generating serial dilutions of each and measuring cell concentrations and turbidity of each sample. We identified linear correlations between cell concentration and turbidity and established standard equations between cell concentration and turbidity for each species. We sampled and quantified algae from a shellfish hatchery using these equations and compared hemocytometer counts. No differences were found (P = 0.174), indicating the accuracy of the equations. We expect that this method can provide a quick, accurate, easy method for shellfish hatcheries to quantify algal concentration and avoid either over- or underfeeding larvae and broodstock.

<p>This publication provides information on the status of oyster fisheries and aquaculture in Florida as well as general information about how oysters are grown in agricultural and restoration systems. It then introduces a series of technologies that have been developed in other US states and in other countries, strategies that may have utility in Florida. Finally, it covers some specifics of the permitting process as it relates to oyster aquaculture in Florida.</p>

In this EDIS publication, we provide information on the current regulatory framework for cell-based seafood production in the United States, food safety considerations, and the path forward for cell-based seafood products to get approved for selling in the marketplace. Additionally, drawing on the available science-based risk analysis methods for seafood production such as Hazards Analysis Critical Control Point (HACCP), we provided a simple hazard analysis to identify the potential seafood hazards that can potentially compromise the safety of cell-based seafood products.
