Ocean warming and acidification is set to impact marine species and ecosystems, as well as the productivity and sustainability of fisheries. Here, we investigated the effects of climate-induced ocean warming and acidification on the growth of sand whiting, Sillago ciliata, a popular recreational and commercial fish species that inhabits estuarine and oceanic waters along the east coast of Australia. Using an orthogonal outdoor mesocosm system, juvenile sand whiting were subjected to current and near-future conditions of water temperature and acidification for a period of three months. Variation in fish growth and otolith oxygen isotopes were analysed across the treatments to determine any influence of the increased water temperatures and acidification. Preliminary results and the direction of future research will be discussed with respect to the potential impact of ocean climate change on whiting and its consequences for associated large-scale commercial and recreational fisheries.
