Summary
This review covers ictalurid catfish biology and culture, focusing on channel catfish and its hybrid with blue catfish. Advances in catfish farming, including genetics and disease control, are vital for the US catfish industry.
Area of Science:
- Aquaculture and Ichthyology, focusing on Ictaluridae catfish species.
Background:
- Ictalurid catfish are significant commercial, aquaculture, and sport fish in the United States.
- Review of historical propagation and spawning techniques for common catfish species.
Purpose of the Study:
- To summarize the biology and culture of ictalurid catfish.
- To emphasize channel catfish and its hybridization with blue catfish.
- To discuss the role of hybrids in the recovery of the US catfish industry.
Main Methods:
- Review of historical data on catfish propagation and spawning.
- Analysis of recent advancements in catfish culture and production.
- Examination of genetic improvement programs and genome-based approaches.
Main Results:
- Channel catfish and its hybridization with blue catfish are crucial for the industry.
- Significant progress in catfish culture elements: environment, management, nutrition, feeding, disease control, and systems.
- Application of genetic improvement, transgenics, and genome-based approaches are transforming catfish production.
Conclusions:
- The channel catfish female × blue catfish male hybrid shows great potential for the US catfish industry.
- Ongoing advancements in culture technologies and genetic strategies are key to future success.
- Genetically modified organisms and genome-based approaches are shaping the future of catfish production and welfare.
