“…The growth rate observed in the present study is close to that estimated for wild H. rufescens in northern California (Rogers-Bennett, Rogers & Schultz 2007). Different environmental factors have been shown to influence growth rate in abalone, including water temperature (Kelly & Owen 2002;Searle, Roberts & Lokman 2006), amount and quality of food (Nidoo, Manveldt, Ruck & Bolton 2006;Cho & Kim 2012), stocking (Huang & Hseu 2010), and this kind of effect cannot be excluded in the Chilean population of red abalone.…”

“…The growth rate observed in the present study is close to that estimated for wild H. rufescens in northern California (Rogers‐Bennett, Rogers & Schultz ). Different environmental factors have been shown to influence growth rate in abalone, including water temperature (Kelly & Owen ; Searle, Roberts & Lokman ), amount and quality of food (Nidoo, Manveldt, Ruck & Bolton ; Cho & Kim ), stocking density (Capinpin, Toledo, Encena & Doi ; Wu, Liu, Zhang & Wang ), oxygen concentration (Harris, Maguire, Edwards & Johns ), dissolved ammonia (Harris, Maguire, Edwards & Hindrum ), stress conditions (Hooper, Day, Slocombe, Handlinger & Benkendorff ), and combinations of some of those factors (Tung & Alfaro ). In red abalone, growth rate has been related with water temperature, food availability and diseases, like withering syndrome (González, Brokordt & Lohrmann ), and the interaction among these factors (Braid, Moore, Robbins, Hedrick, Tjeerdema & Friedman ).…”

Changes of heritability and genetic correlations in production traits over time in red abalone (Haliotis rufescens) under culture

Red abalone Haliotis rufescens is one of the most valuable mollusks in the international market, but it has a low growth rate. A breeding program is being developed to increase its growth rate in Chile. We estimated the changes in direct heritability (h2), maternal/common environments heritability (m2) and genetic correlations (rG) of growth traits (shell length and width, total mass, flesh mass and foot protein as an indicator of meat quality) measured during 2 years (every 4 months) from the juvenile stage (27 months) to the adult harvesting age (51 months), in 60 full‐sib red abalone families. Heritabilities for growth traits measured in juveniles and young adults (27–35 months of age), were low (0.07–0.17) and not significant. Initial low h2 were associated with significant amounts of maternal/common environmental effects (m2 = 0.4). In young adults and abalone near the harvest age (39–51 months of age) h2 were much higher (0.32–0.75). These results emphasize the importance of multiple estimations of h2 over time. Among meat quality traits, only the h2 for the flesh mass for adults at harvesting age was significant (0.15). We observed strong positive rG (>0.9) between shell sizes (easy to measure) and total and flesh masses (trait more related to market value than shell sizes but harder to measure) for adults at harvesting age. Thus, if the 5% largest 51 month old abalone were selected from the population as broodstock we expect a positively correlated response on flesh mass of 23.4%.

“…Haliotis laevigata, H. rubra and Haliotis corrugata maintain a constant MO 2 within their T pref (Harris et al 2005;Romo et al 2010; Table 1) and are often found at their T pref in their natural habitat (Dahlhoff & Somero 1993). This temperature also corresponds to the highest growth rate in most species Harris et al 2005;Green et al 2011;Cho & Kim 2012).…”

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.

“…Chang and Wang () reported the effects of temperature (14, 17 and 20°C) on the energy budget of H. discus hannai (experimental body weight: 0.08–3.23 g/ind), finding that the growth energy was the highest at 20°C. Cho and Kim () found the weight gain of H. discus hannai (experimental body weight: 4.6–9.1 g/ind) decreased with the increasing temperature (20, 23 and 26°C), but there was no significant difference.…”

The growth and carbon allocation of abalone (Haliotis discus hannai ) of different sizes at different temperatures based on the abalone-kelp integrated multitrophic aquaculture model

The integration of shellfish and seaweed is an important and successful IMTA model. The IMTA of abalone and kelp has been well-practiced in Sanggou Bay, China. In the present study, the growth and carbon allocation of abalone (Haliotis discus hannai) of different sizes (S, small; M, medium; L, large) fed kelp (Laminaria japonica) were investigated at different temperatures (10, 14, 18 and 22°C). A twoway ANOVA showed that both size and temperature significantly affected the specific growth rate (SGR), food consumption (FC), feed conversion ratio (FCR) and apparent digestion rate (ADR) of abalone (p < 0.05), and significant interactions between the two factors were detected (p < 0.05). Curve estimation showed a significant quadratic relationship between SGR and temperature in each size class (p < 0.05). The two-way ANOVA also showed that both size and temperature significantly affected all the measures of carbon allocation (p < 0.05) except for the carbon lost in metabolism (p > 0.05). All the measures of carbon allocation increased with the increasing temperature. It was concluded that it was better to culture H. discus hannai with a body weight less than 15 g at 20-22°C, and more than 15 g at 15-20°C to achieve good growth. The growth carbon of kelp around the abalone farm should be more than the metabolic carbon expenditure, which means the growth of kelp around the abalone farm should be more than 23.06%-61.91% of food consumption to maintain a carbon sink IMTA system without any carbon release. K E Y W O R D Sabalone, carbon, growth, integrated multitrophic aquaculture, kelp, temperature | INTRODUCTIONAquaculture is increasingly important worldwide because of the increasing food demand for the growing global population (FAO, 2016). Some aquaculture practices, however, have a negative effect on the environment. For example, aquaculture species consuming feed (e.g., finfish) deliver high-quality protein while also increasing nutrient input into the environment. In a review on the environmental impact of marine fish farming, Wu (1995) estimated that 85% of phosphorus, 80%-88% of carbon and 52%-95% of nitrogen may be lost into the environment due to lost feed, excretion by fish, fish respiration and defecation. Fortunately, some aquaculture models have successfully reduced the negative effects of feed-based aquaculture.
