Project title:

The thermal stress sensitivities of the early life stages of Mytilus galloprovincialis mussels from the south and west coast of South Africa

Aldi is interested in integrating knowledge of the physiology, life cycles and biology of marine invertebrates with aquatic environmental interactions, both in natural ecosystems and in culture environments. During her MSc, Aldi characterised the growth, morphological and feeding response of cultured Pacific oysters (Crassostrea gigas) to different South African coastal farming localities in transplant experiments. Her supervisors included Dr Sue Jackson and Dr Tamara Robinson (Department of Botany and Zoology, University of Stellenbosch). Aldi subsequently moved to Rhodes University for a PhD project on the effect of macroalgae supplementation on the digestive physiology of cultured abalone fed formulated feeds. She studied the effect of macroalgae on the gut microflora and digestive enzyme levels of abalone and have also been involved with research on the effects of carbohydrate and protein ingredients on the metabolism and gut microflora of dusky kob. For the past year and as part of a Post-Doctoral Fellowship at the South African Institute for Aquatic Biodiversity, she conducted respirometry experiments to compare the temperature response of the settlers and recruits of Perna perna and Mytilus galloprovincialis mussels.

Research Interests:
