“…However, the number of successful spawning events did not change when handling was further increased by fortnightly chipping (removal from the substrate) for weight and length measurements. Yet, the number of eggs produced by the female was twice as high when not handled compared to handled individuals, although this result was presented with insufficient numbers of replicates to reach statistical power (Freeman et al 2006).…”

“…The impact of the handling processes on either broodstock or early life stages is relatively unknown despite the fact that precipitate spawning occurs when abalone are exposed to stressful conditions (Freeman et al . ). Farmers take advantage of this behaviour for spawning by exposing their broodstock to changing temperatures and UV irradiated water (Grubert & Ritar ; Daume ).…”

“…Li (2004) published a detailed protocol to establish an abalone farm for H. rubra and H. laevigata, containing information about broodstock collection and maintenance, spawning and fertilization methods, hatch-out and larval rearing as well as grow-out maintenance for juveniles off plates (Li 2004). The impact of the handling processes on either broodstock or early life stages is relatively unknown despite the fact that precipitate spawning occurs when abalone are exposed to stressful conditions (Freeman et al 2006). Farmers take advantage of this behaviour for spawning by exposing their broodstock to changing temperatures and UV irradiated water (Grubert & Ritar 2005;Daume 2007).…”

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.

“…The high value of abalone has stimulated considerable effort into the development and optimization of intensive abalone culture (Cook & Gordon, 2010). The successful culture of this species relies on understanding and managing many aspects of production, including reproduction (Freeman et al., 2006), nutrition (Britz, 1996a, 1996b; Mai, Mercer, & Donlon, 1994, 1995a, 1995b), dietary manipulation (Bansemer et al, 2016a; Bansemer et al, 2016b; Stone, Bansemer, & Harris, 2014; Stone et al, 2014), ecology and habitat (Shepherd, 1973; Shepherd & Turner, 1985), and environmental requirements (Freeman, 2001).…”

‘Energy budgets for greenlip abalone ( Haliotis laevigata Donovan) fed live macroalgae compared to commercial formulated diets’

et al. 2020

Energy budgets were developed for greenlip abalone (Haliotis laevigata) under different feeding scenarios to predict growth, metabolic and waste outputs. The energy budgets of abalone fed live macroalgae (Ulva sp. or Gracilaria cliftonii) and an equal mix of those two macroalgae species with and without nutrient enrichment, or one of three control formulated commercial diets, at 22°C for 93 days were investigated. Among non‐enriched algal treatments, abalone fed G. cliftonii and mixed diet treatments had significantly higher ingested feed energy and absorbed energy than those fed Ulva sp. Abalone fed non‐enriched G. cliftonii invested significantly more energy into somatic growth than those fed Ulva sp. and the mixed diet treatment. For diets with nutrient enrichment, ingested feed energy and absorbed energy rate of abalone fed G. cliftonii and mixed diet treatments were significantly higher than those fed Ulva sp. Nutrient enrichment increased crude protein in live macroalgae, and ammonia excretion energy rate was higher for abalone fed enriched macroalgae compared to non‐enriched. Abalone fed the control commercial diets spent more energy in all components compared to those fed the live macroalgae treatments. The major component of the energy budgets in abalone fed the commercial diets and live macroalgae diets was somatic growth energy, ranging from 25.5% to 37.7% of ingested feed energy, except for abalone fed live Ulva sp. where the major component was respiration energy (38.5%). Overall, abalone fed the formulated diets or live non‐enriched G. cliftonii could increase ingested feed energy, absorbed energy and somatic growth energy.
