Waldo’s research interest revolves around nutrition and physiology of commercial aquaculture species. This involves understanding how production strategies and environmental stressors impact growth efficiency, health and product quality, and developing new feeding strategies accordingly. This implies collaborating with industry partners in the evaluation and development of novel feed ingredients and additives and in the transfer of research findings into commercial application. One of his major interests is the use of proteomics technologies to approach nutritional research and in particular to identify molecular changes and biomarkers associated with gut health.

Trained in Spain (DVM, University of Zaragoza), Canada (MSc, University of Saskatchewan) and Australia (PhD, University of Tasmania), Waldo has 12 years of combined academic and industry experience in animal nutrition with focus on aquaculture species. As a new lecturer at JCU, he is excited about providing students with hands-on learning experience and understanding of the importance of the industry-academia interface.

Fisheries Research & Development Corporation - Annual Competitive Round

Assessing the nutritional quality in Australian barramundi

Indicative Funding
$16,000 over 1 year
To assess the variability in nutrient composition, specifically omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA) and minerals, in the fillet of farmed Australian barramundi (Lates calcarifer). This information will be used by the barramundi industry to market the health benefits of its farmed product.

Fisheries Research & Development Corporation - Annual Competitive Round

Real time monitoring of water quality and mechanisation of pond management to boost productivity and increase profit

Indicative Funding
the cost of electricity to driver pond aerators is one of the major costs of barramundi production. This project looks at the use of oxygen sensors linked to controllers that switch on and off paddlewheels once oxygen levels reach 80o% saturation. The effects of the controllers on cost of electricity use, and the pond ecosystem including nutrient levels, algae composition and metals will be assessed. The project will deliver an understanding if electricity costs can be reduced using controllers without reducing production or adversely affecting the pond environment.
