It can be attributed to the visual and chemical perception, as observed for the channel catfish, Ictalurus
punctatus (Rafinesque, 1818) (Valentincic and Caprio, 1994), and also the mechanical perception, as verified for the jundia Rhamdia quelen (Quoy and Gaimard, 1824) (Rodrigues-Galdino et al., 2009).
The experiment showed the survival of 98.87%, which agrees with other carnivorous and omnivorous fish in growth experiments; rainbow trout Oncorhynchus mykiss 96.3% (Garcia-Macias et al., 2004) and channel catfish Ictalurus
punctatus 97% (Yildirim et al., 2007).
A pesar de que el Catfish, Ictalurus
punctatus no pertenece a la familia Pimelodidae, es una de las especies de siluridos mas estudiada en cuanto a los requerimientos nutricionales y es importante tenerla en cuenta (Tucker & Robinson, 1991).
Organic selenium sources, selenomethionine and selenoyeast, have higher bioavailability than an inorganic selenium source, sodium selenite, in diets for channel catfish (Ictalurus
Widely distributed throughout many FW systems of North America, the channel catfish (Ictalurus
punctatus) can also be found in brackish coastal environments (Perry 1969).
With the improvements in next generation sequencing technologies in the past few years, many genome projects of aquaculture fishes have been reported, including Atlantic salmon (Salmo salar) , Atlantic cod (Gadus morhua) , rainbow trout (Oncorhynchus mykiss) , Japanese flounder (Paralichthys olivaceus) , half-smooth tongue sole (Cynoglossus semilaevis) , platyfish (Xiphophorus maculatus) , common carp (Cyprinus carpio) , and channel catfish (Ictalurus
punctatus) , and molecular markers of the shared genomic loci among individuals have been obtained for genotype-phenotype linkage analysis.
Six species of fish were identified as prey; the introduced Oreochromis aureus and Cyprinus carpio were the main prey, but native species as Moxostoma austrinum and the three endemics Ictalurus
dugesii, Cichlasoma beani, and Chirostoma arge were also found in spraints.
Conversely, TIEMAN & GOODWIN (2001) tested hydrogen peroxide at a concentration of 25mg [L.sup.-1] (daily) against ichs in Ictalurus
punctatus without any satisfying results, similar to in vitro trials (<50mg [L.sup.-1] for 10h) targeting the trophont stage, provided by LAHNSTEINER & WEISMANN (2007) and in current study.
Legally, only one type of fish (the Ictalurus
genus) can be called "Catfish" in the United States.
Channel catfish (Ictalurus
punctatus) are a popular target for Nebraska anglers.
