Biotech Catfish: Engineering Disease Resistance with Alligator DNA
Researchers in Alabama Successfully Combine Catfish and Alligator Genes in Groundbreaking Experiment
America's dinner tables can't get enough catfish, and fish farms are the backbone of this multi-billion-dollar industry. However, disease transmission within these farms poses a significant problem. Scientists at Auburn University aim to fix that with a bold solution: genetically modifying catfish to resist diseases, using alligator DNA as their blueprint.
As Insider reported, alligators harbor a gene in their intestines known as cathelicidin, an antimicrobial peptide that aids in disease fighting. After employing CRISPR, a gene-editing tool that carves DNA with precision, these researchers inserted the alligator gene into catfish DNA. The results were impressive: their lab-raised catfish exhibited remarkable disease resistance, boasting survival rates "two and five-fold higher" than wild catfish.
The research team's findings were detailed in a yet-to-be-peer-reviewed paper published in January. However, the use of CRISPR technology on fish has raised questions since it has primarily been studied on mammals. Moreover, the insertion of the cathelicidin gene intentionally reduced the catfish's reproductive capabilities, aiming to prevent genetic contamination with wild populations.
Assuming commercialization and regulatory approval, these transgenic catfish could bring about waste reduction benefits, as Americans gobble up nearly 307 million pounds of the fish annually. Rex Dunham, the researcher behind the project, believes that consumers would accept genetically engineered catfish, comparing it to eating alligator meat and arguing that the alligator gene's protein loses biological activity upon cooking.
Genetically engineered fish, such as AquAdvantage salmon, are not novel to the market; however, the regulatory process is lengthy and thorough, with assessments focusing on the environment, food safety, and ethical concerns. As of now, the GM catfish with alligator genes are primarily in the experimental stage, awaiting wider approval for commercial production.
When it comes to the fusion of genes from distantly related species like catfish and alligators, heated debates about ethics and animal welfare persist. In addition, there are concerns about potential unforeseen ecological impacts and consumer acceptance. A holistic examination of the potential risks and benefits of this innovative approach is crucial before we start seeing genetically modified catfish on our dinner plates.
