“…The increase in feed intake from 22°C to 26°C in the present study is unexpected, as the animals are near their thermal maximum of 27.5°C (Gilroy and Edwards, 1998), hence generally it would be expected that the feed intake at 26°C would be lower than at 22°C. For example, both Lange et al (2014) and Stone et al (2014) reported an approximate 50% reduction in feed intake by 2 and 3-year-old greenlip abalone between 22 to 26°C when fed the same diet as used in the current study. Abalone in the present study were likely able to cope at 26°C better than those in the Lange et al (2014) and Stone et al (2014) studies, due to lower stocking densities in combination with better water quality.…”

“…Previous studies investigating abalone diets compared their effect on growth rates (Naidoo et al 2006;Dang et al 2011;Stone et al 2013;Bansemer et al 2014), nutritional and health benefits (Shpigel et al 1999;Schaefer et al 2013;Stone et al 2014;Lange et al 2014), foraging behaviour in the wild (Tutschulte & Connell 1988), feeding preferences (McShane et al 1994) and feeding stimuli (Allen et al 2006). Little is known about the effect of feed availability and diet type on the feeding behaviour of abalone.…”

Abalone farmed in Australia are predominantly fed formulated feeds, while in the wild, their diet consists of a mix of macroalgae. Here we investigated the feeding behaviour of juvenile greenlip abalone, Haliotis laevigata; fed live macroalgae and formulated diets at different rations; and observed their feeding behaviour using a novel ventral video monitoring technique. Four different diets (commercial chip, experimental flake, Ulva sp. and Gracilaria cliftonii) at two feeding rations (excess vs. restricted) were tested. Diet type had no effect on abalone movement, but macroalgal diets resulted in higher feed intakes. Restricting feed rations induced greater movement. Abalone moved little during the light period and moved mostly during darkness, except for animals on the restricted feed ration where feeding commenced during the light period. On farms, this phenomenon may be a useful behavioural indicator for identifying underfed abalone. Despite their lower intake, formulated diets promoted higher energy and nutritional intake, indicating that quantity of feed consumed is not solely indicative of nutritional gain. From a research perspective, the novel ventral monitoring method has created opportunities for further behavioural studies in molluscs.

“…Diet quality can also affect tolerance to stressors. Providing a high antioxidant diet of grape seed extract and the macroalga Ulva lactuca improved high temperature survival of the greenlip abalone H. laevigata (Lange et al 2014). Experimental evidence suggests that purple sea urchins Paracentrotus lividus can improve adaptation to acidification through modulation of the dietary Mg:Ca ratio (Asnaghi et al 2014).…”

Increases in global population and seafood demand are occurring simultaneously with fisheries decline in an era of rapid climate change. Aquaculture is well positioned to help meet the world's future seafood needs, but heavy reliance of most global aquaculture on the ambient environment and ecosystem services suggests inherent vulnerability to climate change effects. There are, however, opportunities for adaptation. Engineering and management solutions can reduce exposure to stressors or mitigate stressors through environmental control. Epigenetic adaptation may have the potential to improve stressor tolerance through parental or early life stage exposure. Stressor-resistant traits can be genetically selected for, and maintaining adequate population variability can improve resilience and overall fitness. Information at appropriate time scales is crucial for adaptive response, such as real-time data on stressor levels and/or species' responses, early warning of deleterious events, or prediction of longer-term change. Diet quality and quantity have the potential to meet increasing energetic and nutritional demands associated with mitigating the effects of abiotic and biotic climate change stressors. Research advancements in understanding how climate change affects aquaculture will benefit most from a combination of empirical studies, modelling approaches, and observations at the farm level. Research to support aquaculture adaptation requires an increasing amount of environmental data to guide biological response studies for regional applications. Increased experimental complexity, resources, and duration will be necessary to better understand the effects of multiple stressors. Ultimately, in order for aquaculture sectors to move beyond short-term coping responses, governance initiatives incorporating the changing needs of stakeholders, users, and culture ecosystems as a whole are required to facilitate planned climate change adaptation and mitigation.
