“…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 ).

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%.

“…Aunque la prevalencia de esta patología no es alta y es altamente dependiente de la temperatura, ha comenzado a ser sujeta de algunos estudios. Es así que González et al (2012) concluyeron que una infección temprana por este patógeno afecta negativamente la actividad fisiológica de H. rufescens, aunque ésta sea asintomática. En un estudio posterior, se ensayó la hibridación inter-específica de las especies H. rufescens y H. discus hannai para obtener un híbrido resistente a esta patología, pero éste también exhibió susceptibilidad a este patógeno (González et al 2014).…”

Excessive fishing effort has led to overexploitation and depletion of major benthic fisheries in Chile, so it has been encouraged cultivation of major overexploited benthic resources in controlled environments, mainly those which are not possible to collect seeds from environment. In this review, the current knowledge on bacteriology associated with shellfish farming in controlled systems in Chile, including both aspects associated with development of infectious diseases of bacterial aetiology as well as the use of microorganisms to reduce mortality of cultured species, is described. The majority of bacteriological studies in Chilean shellfish culture were done in the Chilean scallop, Argopecten purpuratus and were related to identifying pathogens isolated from mass mortalities occurred in larval and/or juvenile cultures and the verification of their pathogenic activity performing bioassays under controlled condition bioassays. There are also a large number of studies on bacteria exhibiting inhibitory activities against shellfish pathogenic and their protective effects under controlled conditions. Despite the above, still are required more studies to know the structure and dynamics of the microbiota associated to mollusk culture, bacterial pathogens and molecular elements encoding for their pathogenicity.

“…Several factors can modify abalone metabolism such as light quality ( H. discus discus , Gao et al , 2016), infection ( H. rufescens and H. discus hannai , González et al , 2012; H. diversicolor , Lu et al , 2017), farm stressors such as density, high temperature and ammonia concentration (see review from Morash & Alter, 2015). To increase our understanding of the effects of environmental and farm stressors upon abalone physiology, it is first necessary to better comprehend the natural temporal variability in abalone metabolism and biology.…”

Seasonal and diurnal variability in carbon respiration, calcification and excretion rates of the abaloneHaliotis tuberculataL.

Abalone (Haliotis spp.) are commercially important marine shellfish species worldwide. Knowledge about the physiology of abalone that impacts life-history traits is important for a better understanding of the biology of the species and the impact of stressful husbandry procedures at different seasons. The present study quantified the seasonal and diurnal variations in four physiological parameters of the European species Haliotis tuberculata, i.e. carbon aerial and aquatic respiration, calcification and excretion rates, and the effect of prolonged aerial exposure upon abalone aerial respiration. We also investigated the effect of individual size upon these physiological parameters. Aquatic respiration and calcification rates showed an allometric relationship with biomass. All parameters showed lower rates in cool season and higher rates in warmer season. Temperature was assumed to be the primary driver of the reported seasonal variability in physiological parameters, although reproductive needs and nutrition may also contribute to the observed patterns. Importantly, abalone did not stop calcifying in winter, and calcified more at night than during the day. Abalone did not respire more underwater at night-time than at daytime, however they excreted more overnight. The low air:aquatic ratio (0.2) is likely to be an energy-saving strategy for emerged H. tuberculata individuals. This study highlights the temporal heterogeneity in physiological rates of H. tuberculata, which constitutes a species recently domesticated in Europe.
