Pathogen-Free Black Tiger Shrimp: Paving the Way for Sustainable Aquaculture in Brazil

Genics, a frontrunner in aquatic pathogen detection and genetic analysis, has released groundbreaking research highlighting the advantages of Brazilian black tiger shrimp (Penaeus monodon) as a viable alternative to Pacific white-leg shrimp (Litopenaeus vannamei) in aquaculture.

Research Collaboration and Findings

Conducted in partnership with the State University of Maranhão and CSIRO, the study examined the pathogen load and genetic diversity of a domesticated population of black tiger shrimp from Ceará, Brazil, over ten generations. Utilizing advanced molecular diagnostics and histopathology, researchers screened 96 shrimp specimens and found no significant pathogens, indicating that this population could serve as a foundation for a specific pathogen-free (SPF) breeding program.

Industry Impact

“This is a pivotal finding for the Brazilian shrimp farming sector,” said Dr. Melony Sellars, CEO of Genics. “By establishing that local black tiger shrimp populations are pathogen-free and genetically diverse, we provide the industry with essential tools to enhance resilience, reduce disease risk, and support sustainable production systems.”

Genetic Analysis Insights

The genetic analysis revealed a low inbreeding coefficient of 0.03 through SNP markers, comparable to international populations in Vietnam and Australia. This suggests the potential for Brazilian broodstock to underpin a structured breeding program aimed at fostering disease resilience and sustainable growth.

“Pathogen-free and genetically diverse populations are critical for aquaculture sustainability,” Dr. Sellars emphasized. “This research not only offers a blueprint for the Brazilian shrimp industry but also highlights the potential for local breeding programs to decrease reliance on imported stocks while mitigating the spread of infectious diseases.”

Importance of Biosecurity and Genetic Diversity

The study underscores the necessity of comprehensive pathogen screening and genetic analysis as vital elements in aquaculture management. Genics’ ShrimpID P. monodon service utilizes high-density SNP markers to accurately assess genetic diversity and trace lineage, equipping shrimp farmers with essential insights for optimizing breeding programs and stock performance. This aligns with Genics’ overarching mission to advance global biosecurity and food security.
