CAT unveils 'practical value' genotyping panel for black tiger shrimp 

The San Diego-based Centre for Aquaculture Technologies (CAT) has introduced a new, value-driven genotyping solution designed for improved efficiency in selective breeding programmes for black tiger shrimp (Penaeus monodon).

The Low-Density (LD) Genotyping Panel empowers hatcheries to make faster, more informed decisions, said CAT. Whether establishing a new breeding programme or optimising an existing one, the LD panel provides the ability to reveal critical insights needed to accelerate genetic progress in P. monodon.

“This panel was built with flexibility and breeding efficiency in mind,” said Dr Klara Verbyla, vice president of genetic improvement at CAT, who is responsible for the team that developed the panel. “It enables essential insights into relatedness, population structure, parentage, and genetic sex - all at a marker density that balances data quality with practical value. It’s designed for programmes that may not need thousands of markers but still require actionable results. The right tool for the task ensures both return on investment and long-term genetic gains.”

Designed for adaptability, the LD panel allows black tiger shrimp producers to align genotyping strategies with specific breeding objectives and budget. CAT said in a press release that with robust internal quality controls and rapid turnaround times, the Centre provides clients with timely, high-confidence data to inform critical selection decisions.

“What sets this panel apart is how well it translates to real-world use,” said Oscar Hennig, senior advisor and CAT’s commercial shrimp production expert. “As a former selective breeding programme manager, I’ve seen firsthand how balancing cost and insight can mean the difference between a breeding program that survives and one that thrives. This tool gives breeding programs a practical way to improve performance - without the unnecessary complexity of non-essential markers.”

A customised solution

CAT said that as competition and innovation in P. monodon genetics grow, its latest offering equips breeding programmes with accessible, customised, and impactful genotyping solutions to stay competitive and optimise their breeding outcomes.

More genotyping options mean greater opportunity for innovation, efficiency, and long-term success in the industry.

“At CAT, our core purpose is to support productivity, sustainability, and global food security,” said Verbyla. “Bringing new genetic tools to market is part of that mission - and this panel is another step toward empowering shrimp producers to achieve their goals.”
