Advanced Technology for Broodstock Management and Research

By Hatchery International staff

A key component to successful aquaculture production lies at the heart of broodstock management. Managers work diligently to produce fish that better meet market demand with better performance through generations of strategic breeding. Regardless of species or location, monitoring broodstock success requires careful analysis of breeding efforts and the ability to trace offspring single individual from hatching to market size and to evaluate growth, disease resistance and other important parameters, through the farming cycle. In this webinar, our panel of experts from Valperca SA, USDA, and Biomar will discuss the benefits of PIT tagging, genetic sampling, and data collection solutions for effective broodstock management and breeding program.

Beat von Siebenthal is the R&D Manager for Valperca SA, operating in the Chavornay and Raron regions of Switzerland. Beat overseas the production of Perch (Perca fluviatilis) in RAS. He is responsible for the ongoing optimization of the rearing conditions and procedures throughout the whole production cycle, from the larvae in the hatchery to the adult fish in the grow-out facility. His background is in evolutionary ecology, fish health and fish welfare.


Dr. Kenneth Overturf gained his PhD in Molecular and Cellular Biology from the University of Nevada-Reno in 1994. After undertaking several research roles, Dr. Overturf began working for the USDA’s Agricultural Research Service (USDA-ARS) as a research geneticist in 2000. He is currently based at the University of Idaho’s Hagerman Fish Culture Experiment Station, located in south-central Idaho, near the centre of the U.S. trout industry. For the past 20 years, one of Dr. Overturf’s main research areas has been utilizing genetic selection to improve fish production within the aquaculture industry, focusing on rainbow trout. His current research involves a holistic approach to understanding the interactive effects of nutrient utilization, animal physiology, water quality, genetics, and management practices to optimize aquaculture production.


Heiden Bliss is the Director of Sales and Marketing for Biomark. Heiden has a degree in Fisheries Resources from the University of Idaho and started his career as a biologist for the Idaho Department of Fish and Game. He began working for Biomark in 2006 on PIT tagging projects, PIT antenna system installations and then into sales/support focused roles. Heiden has worked with aquaculture and broodstock customers around the world to find the best solutions for their breeding programs.
