Study evaluates production characteristics, minerals, off-flavors and water quality dynamics on channel catfish reared in used and in new biofloc water.   

Study quantifies temporal changes of selected fatty acids from six fish species subjected to two handling and three storage methods compared to samples that were processed immediately. 

This study evaluated the performance and production of channel catfish and freshwater prawns and three varieties of lettuce – American, Romaine and Rose – in a research aquaponics system. 

This study evaluated the feasibility of a portable, hand-held micro near-infrared spectrometer to objectively determine the stage of maturity in channel catfish. Such a rapid, non-invasive method to stage fish maturity in hatcheries would improve the efficiency of hatchery production. 

Scott Nichols concludes his four-part series about GM foods with a simple question about transgenic animals: Are they truly meeting a need? We need more food and we need better nutrition. Both desires should be achieved without increasing environmental impacts. 

This study investigated factors that predisposed catfish to motile Aeromonas septicemia (MAS) caused by virulent Aeromonas hydrophila (vAh). Results revealed that wounding on fish body surface was important for vAh infection and disease development. 

A study was conducted to assess the feasibility to grow Channel catfish (Ictalurus punctatus) in an outdoor biofloc system during winter in a temperate zone. High biomasses of market-size channel catfish were successfully maintained through the winter with high survival and in good condition in both treatments. 

In a study, the authors evaluated the immune responses and host protection of hybrid catfish and channel catfish against the ich parasite (Ichthyophthirius multifiliis). 

A laboratory study compared conventional soybean meal (CSBM) and low-oligosaccharide soybean meal (LOSBM) as the main protein sources in 28 percent or 32 percent protein diets for channel catfish. 

In studies that used biofloc systems to culture channel catfish, culture tanks were susceptible to episodes of geosmin and 2-methylisoborneol and subsequent bioaccumulation of off-flavors in catfish flesh. 

Hybrid catfish offer production advantages over channel catfish. Trials show greater survival, faster growth and shorter production cycles. 

Although there is increasing interest in blue catfish, a potential disadvantage of the fish when compared to channel catfish is their reported poorer tolerance of low dissolved-oxygen concentrations. 

The authors conducted a study to determine whether channel catfish systematically develop off-flavors after partial harvest as well as the possible origins of the flavors. 

Essential oils are linked to livestock performance gains. In research with channel catfish, inclusion resulted in greater feed consumption and weight gain. 

USDA and partners are developing channel catfish that exhibit superior growth, fillet yield and resistance to enteric septicemia. Although ongoing research continues to select the USDA lines for better performance, studies comparing the strains have been inconclusive.
