Dr. Jake Goodall, post-doc at the Faculty of Life and Environmental Sciences at the University of Iceland, will present his research on reproductive performance in the Giant Tiger Shrimp, Penaeus monodon:
The Giant or Black Tiger Shrimp, Penaeus monodon, is an economically significant aquaculture species, producing 4.5 million tonnes of product annually at a value of US$ 23.5 billion. Recent innovations in the domestication and selective breeding of P. monodon have resulted in significant improvements in growth rate, survival and pathogen tolerance. However, the reproductive performance of domesticated stocks remains inferior when compared to their wild-caught counterparts. The reduced reproductive performance of domesticated P. monodon is largely underpinned by a poor understanding of the nutritional requirements for reproduction in the species, particularly for female broodstock. The following lecture details emerging research from Australia, in which assessments of nutrition, biochemistry and regulatory gene pathways have begun to shed light on key factors underlying reproductive dysfunction in domesticated P. monodon broodstock.
