Introduction
I'm a Marine Biologist and Seaweed Marine Scientist.
My current research focuses on understanding the different carbon uptake strategies of Tasmanian marine seaweed, especially Reds, due to Tasmania's high proportion of non-CCM seaweed, i.e. algae that rely exclusively on CO2 for photosynthesis.
This will allow us to predict the physiological responses of these seaweed to increasing CO2 and ocean acidification and, to take conservation actions to protect these marine ecosystems.

Effects of pH, temperature and light on carbon metabolism in Macrocystis pyrifera gametophytes
DIC affinity of Tasmanian red seaweeds (Rhodophyta) and their physiological responses to future ocean acidification

In teleosts, peripheral serotonin (5-HT) and melatonin (MEL) are synthesised in the gastrointestinal tract (GIT) and regulate secretion and motility processes. Their production is regulated by diet and the passage of food through the GIT. This study aimed to evaluate how intestinal 5-HT, melatonin, and the activity of digestive enzymes varied with...
It has been suggested that supplementing fish diets with L-tryptophan (L-Trp) and melatonin (MEL) may attenuate stress; however, little clarity exists regarding the physiological effects of both additives and the associated mechanisms in attenuating the stress response. We investigated how MEL and L-Trp in the diet affects the physiology and acute...
Several studies describe gastrointestinal tract (GIT) melatonin (MEL) synthesis from 5-HT, which itself derives from the essential amino acid L-tryptophan (L-trp) in the intestine. Supplementing L-trp and MEL through diet has shown social-response effects and suppresses neuroendocrine stress in teleosts. In this study, the effects of a MEL and L-tr...
Although Caligus rogercresseyi negatively impacts Chilean salmon farming, the metabolic effects of infection by this sea louse have never been completely characterized. Therefore, this study analyzed lactate responses in the plasma, as well as the liver/muscle lactate dehydrogenase (LDH) activity and gene expression, in Salmo salar and Oncorhynchus...
The sea lice Caligus rogercresseyi constitute a major problem affecting the Chilean salmonids industry, having a strong negative effect over the production of Atlantic salmon (Salmo salar) and Rainbow trout (Oncorynchus mykiss). Caligidosis has been described affecting Atlantic salmon and rainbow trout more than Coho salmon (Onchorynchus kisutch).T...
Salt baths in the production system of salmonids in fresh water, are important for the prevention and control of different diseases such as saprolegnia fungus. This standard procedure generates a rapid depletion of O2 in the water, leading to a significant increase of CO2, affecting blood parameters associated with animal welfare, such as Na⁺, Cl-,...
