Steve M Arce
Director of Technical Services
Kona Bay Shrimp – Hendrix Genetics Aquaculture Unit

Steve M Arce has over 25 years of shrimp technical and management experience, including the research and development of SPF L. vannamei shrimp stocks from the Oceanic Institute in Hawaii (part of the USMSFP). He has also provided shrimp breeding and biosecurity consulting services in both Latin America and Asia for both government institutions as well as private commercial companies. Since March 2016, Steve is the Director of Technical Services (Asia Shrimp Unit) for Kona Bay Shrimp – Hendrix Genetics Aquaculture Unit, Hawaii, USA. He is responsible for international technical support of SPF L. vannamei broodstock, establishment of new global markets for SPF shrimp lines, logistical support and development of more efficient distribution models for major markets. His focus is also on biosecurity, disease management and best management practices for successful shrimp production. Previously, Steve was Research Associate, Marine Shrimp Program, the Oceanic Institute, Waimanalo, Hawaii and maturation and hatchery of the marine shrimp L. vannamei, including reproduction of specific pathogen free (SPF) stocks. He was responsible for carrying out breeding plans including mating strategies to produce distinct families used in a selective breeding program.

Session 6 Weak Links In The Supply Chain
Presentation Bridging The Gap: Genetic And Hatchery Considerations For A Maturing Shrimp Industry


Genetics is one of the single most important drivers of improvement in shrimp aquaculture. Performance is an interaction between genetics and environment but due to innovative breeding technologies, genetic progress is moving faster than ever. Combining the development of Broodstock Multiplication Centers (BMCs) to reduce the stress of transport and acclimatize stocks to local environmental conditions, as well as incorporating adaptive strategies to support genetically improved stocks, is critical to the continued development of the global industry.  Hatchery management practices, including maturation and feed input which protect the health of the animal while supporting increase nutritional requirements are also essential components as the industry moves forward.

This presentation will focus on: 1) the establishment of BMCs to avoid logistical issues associated with long-distance air transport and biological benefits to this approach; 2) the importance of appropriate hatchery management and feed input to protect the health status of stocks, promote high quality post larvae production, and mitigate disease outbreaks; and 3) the implementation of genomic selection and precision breeding to boost genetic progress with more accuracy.

The global shrimp industry is multi-faceted and the topics covered may serve to overcome some of the “weak links” currently being faced. Stakeholder adaptation to a new management paradigm based on the use of disease-free genetically improved stocks will support optimization in the shrimp aquaculture value chain as the industry matures.
