“…Blue Catfish has already established outside of its native range within North America (Bonvechio et al ., ). Additionally, Blue Catfish has been genetically crossed with Channel Catfish ( Ictalurus punctatus ) in the U.S. aquaculture industry to produce a high growth hybrid with increased disease resistance (Arias et al ., ; Bosworth & Waldbieser, ). Blue Catfish and its hybrids thus have the potential to hybridize with wild native Channel Catfish in the Great Lakes.…”

Aim Impacts of non-native species have motivated development of risk assessment tools for identifying introduced species likely to become invasive. Here, we develop trait-based models for the establishment and impact stages of freshwater fish invasion, and use them to screen non-native species common in international trade. We also determine which species in the aquarium, biological supply, live bait, live food and water garden trades are likely to become invasive. Results are compared to historical patterns of non-native fish establishment to assess the relative importance over time of pathways in causing invasions. Location Laurentian Great Lakes region.Methods Trait-based classification trees for the establishment and impact stages of invasion were developed from data on freshwater fish species that established or failed to establish in the Great Lakes. Fishes in trade were determined from import data from Canadian and United States regulatory agencies, assigned to specific trades and screened through the developed models.Results Climate match between a species' native range and the Great Lakes region predicted establishment success with 75-81% accuracy. Trophic guild and fecundity predicted potential harmful impacts of established non-native fishes with 75-83% accuracy. Screening outcomes suggest the water garden trade poses the greatest risk of introducing new invasive species, followed by the live food and aquarium trades. Analysis of historical patterns of introduction pathways demonstrates the increasing importance of these trades relative to other pathways. Comparisons among trades reveal that model predictions parallel historical patterns; all fishes previously introduced from the water garden trade have established. The live bait, biological supply, aquarium and live food trades have also contributed established non-native fishes.Main conclusions Our models predict invasion risk of potential fish invaders to the Great Lakes region and could help managers prioritize efforts among species and pathways to minimize such risk. Similar approaches could be applied to other taxonomic groups and geographic regions.

“…Concerted efforts to stock blue catfish have been made in states such as Texas, where >10 000 000 fingerlings have been released (Bartram 2010), while they have been introduced widely outside their native range by anglers (Schloesser et al 2011). Additionally, farm culture of a blue catfish 9 channel catfish (Ictalurus punctatus) artificial hybrid (Giudice 1966;Bosworth & Waldbieser 2014) has increased dramatically in the southeast United States in the past decade, necessitating the development and maintenance of blue catfish broodstock lines and strains.…”

Blue catfish, Ictalurus furcatus, are valued in the United States as a trophy fishery for their capacity to reach large sizes, sometimes exceeding 45 kg. Additionally, blue catfish × channel catfish (I. punctatus) hybrid food fish production has recently increased the demand for blue catfish broodstock. However, there has been little study of the genetic impacts and interaction of farmed, introduced and stocked populations of blue catfish. We utilized genotyping‐by‐sequencing (GBS) to capture and genotype SNP markers on 190 individuals from five wild and domesticated populations (Mississippi River, Missouri, D&B, Rio Grande and Texas). Stringent filtering of SNP‐calling parameters resulted in 4275 SNP loci represented across all five populations. Population genetics and structure analyses revealed potential shared ancestry and admixture between populations. We utilized the Sequenom MassARRAY to validate two multiplex panels of SNPs selected from the GBS data. Selection criteria included SNPs shared between populations, SNPs specific to populations, number of reads per individual and number of individuals genotyped by GBS. Putative SNPs were validated in the discovery population and in two additional populations not used in the GBS analysis. A total of 64 SNPs were genotyped successfully in 191 individuals from nine populations. Our results should guide the development of highly informative, flexible genotyping multiplexes for blue catfish from the larger GBS SNP set as well as provide an example of a rapid, low‐cost approach to generate and genotype informative marker loci in aquatic species with minimal previous genetic information.

“…The strain of the female parent of hybrid catfish appears to have a major impact on reproductive performance with regard to fry output. However, Bosworth and Waldbieser (2014) evaluated two diallel crosses with the D&B strain of Blue Catfish and three strains of Channel Catfish females on the production and performance of hybrid catfish progeny. In evaluating the combining abilities of D&B strain males with Channel Catfish females, they found that the dam (2014) compared the effect of two strains of Blue Catfish-Rio Grande and Alabama-sired to four strains of Channel Catfish to produce hybrid catfish progeny.…”

“…However, the male parent of the hybrid catfish-Blue Catfish-is less domesticated (Dunham et al 1994), and little or no selection or genetic improvements have been attempted. Natural or induced spawning of Blue Catfish is often difficult and hence represents a partial explanation for the lack of breeding programs to improve the genetics of Blue Catfish (Bosworth and Waldbieser 2014).…”

This study examined the influence of strain of sire on hybrid catfish embryo production and performance of fingerlings under commercial conditions. Four hundred 4‐year‐old female Gold Kist strain Channel Catfish Ictalurus punctatus were induced to spawn in eight spawning trials. The stripped eggs were fertilized with the sperm of either D&B or Rio Grande Blue Catfish I. furcatus to produce D&B or Rio Grande hybrid catfish embryos. Testes weight (g/kg body weight [BW]) was higher in Rio Grande (1.98 ± 0.28 g/kg BW) than in D&B (1.02 ± 0.12 g/kg BW) Blue Catfish males. Hatching parameters between Rio Grande and D&B hybrids did not differ. Approximately 100,000 hybrid catfish fry produced from each spawning trial were stocked in an individual 0.4‐ha pond to raise fingerlings. Four ponds of D&B and four ponds of Rio Grande hybrids were stocked in eight ponds of identical conditions at the same time. The mean individual BW of D&B hybrid fingerlings (38.5 g) was higher than that of Rio Grande hybrid fingerlings (32.5 g) at 9 months of age. Mean survival (99.3%), production (8,875 kg/ha), and feed conversion (1.14) of D&B hybrid catfish fingerlings were superior to Rio Grande hybrid catfish fingerling survival (92.1%), production (7,664 kg/ha), and feed conversion (1.23), the catfish being raised in replicated earthen ponds under farm conditions. While the D&B strain of sire improved the performance of hybrid catfish fingerlings, it had minimal influence on hybrid catfish fry production.
