“…In the flow‐through system, nearly 15–30% of the production costs are associated with the maintenance of a high rate of exchange. One way to decrease the cost of production associated with constantly pumping water through the abalone grow‐out tanks can be with the use of recirculating systems (Badillo, Segovia & Searcy‐Bernal 2007). For a recirculating system to be considered a closed system, it should have <10% of water exchange per day of the total volume of the system (Masser et al 1992; Loyless & Malone 1997).…”

Commercial abalone culture is carried out using flow‐through systems with a high water volume exchange in Baja California, Mexico. The objective of this work was to compare the growth rate and survival of red abalone cultured in two systems. Flow through (daily water exchange rate of 800%) and recirculating systems consisted of a 250 L fibreglass tank and constant aeration, but biofiltration in the recirculating system was provided with a 28 L (1 ft3) bubble‐washed bead filter. Water variables were measured either daily (dissolved oxygen, temperature, pH and salinity) or three times a week (total ammonia nitrogen, nitrate‐nitrogen, nitrite‐nitrogen and alkalinity). Shell length was measured every 2 weeks for 18 weeks. Only the alkalinity and pH were significantly different due to the addition of sodium bicarbonate to the recirculating system. Abalone growth rate was 26.1 ± 15.96 μm day−1 in the recirculating systems and 22.21 ± 18.69 μm day–1 in the flow‐through systems. The final survival was 78.74% in the recirculating systems and 71.82% in the flow‐through systems. Significant differences in the final size and survival of the abalones were found between systems (P<0.05). Therefore, recirculating aquaculture systems is a feasible alternative for juvenile red abalone culture.

“…For the two abalone species ( H. corrugata and H. tuberculata ) tested above 500 individuals m −2 , there appears to be no loss in growth rate (gram or mm per month) with increasing density (Mgaya & Mercer ; Badillo et al . ) suggesting that at least these species can be cultures at extremely high density with no loss in growth. It would be interesting to determine whether the Australian species behave in the same manner at higher stocking densities.…”

“…At high stocking densities, growth of individuals is often below the optimum rate, but maximal biomass gain counterbalances the loss and ultimately yields the most profit (Mgaya & Mercer 1995;Wassnig et al 2009Wassnig et al , 2010. However, there is ongoing research on profitability with regard to stocking density and growth of abalone in various culture systems (Badillo et al 2007;Park et al 2008;Wu et al 2009;Minh et al 2010;Encena et al 2013;Qi et al 2013;Wu & Zhang 2013). Douros (1987) supplied the first evidence that abalone will stack on each other if the number of individuals in a given area is too high (Douros 1987).…”

Many abalone farms are reliant on coastal water inputs which are subject to fluctuations in environmental variables such as temperature, oxygen, CO 2 and salinity. Near future climate change scenarios predict that there will be more frequent extreme weather events which can exacerbate these fluctuations and potentially be deleterious to farmed abalone where these variables remain largely uncontrolled. In this review, we have taken an in depth examination of current literature on the effects of environmental stress on abalone physiology and metabolism and how this affects their health and growth. In conjunction, we have also reviewed the effects of farm-specific stressors such as ammonia, stocking density, handling, nutrition and disease and the synergistic effects of these and environmental stressors on abalone physiology. We have identified currents gaps in our knowledge of this under-studied species and have made predictions on the effects of climate change on future abalone production with suggestions for future research. In summary, it is expected that abalone will show reduced growth rates as more energy is invested in combating stresses rather than growth. Furthermore, disease outbreaks may become more frequent with greater fluctuations in temperature and salinity, both of which have large-scale effects on immunity. The current body of knowledge is mainly on whole animal effects of stresses, but we know very little of their mechanistic foundation. Research in this area as well as investments in infrastructure will be pivotal in identifying and implementing strategic interventions to maintain a sustainable abalone industry in Australia.
