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.

Optimal dietary digestible protein to energy ratios in White Banana Prawns (Fenneropenaeus merguiensis) as affected by temperature

Indicative Funding
The objective of this project is to determine the optimum dietary P (protein) : E (energy) ratio for Banana prawns at two different temperatures. Two feeding trials of 42 days each (November-December and December-January) will be conducted at MARFU to determine the optimal digestible P:E ratios at 25 degrees C and 30 degrees C, respectively. This information will optimize the quality of formulated feed for Banana ;prawns and will reveal whether dietary adjustments are required during the winter season.

Development of dry pelleted feed and nutritional trials for grower crocodiles

Indicative Funding
$29,313 , in partnership with HL Australia Pty Ltd ($29,313 over 2 yrs)
The project will develop and evaluatel manufactured pelleted feed for Australian crocodile, Crocodylus porosus, under commercial conditions. This project will produce a tailored pellet leading to productivity gains in commercial crocodile production by reducing feed operating cost and by placing a more valuable product on the market. The primary beneficiary of this research will be HL Australia Pty Ltd. The beneficiary has the necessary infrastructure to test feeds aligned with R&D objectives.
