“…The specific growth rate of abalone receiving the E. ludwigii supplemented diet was 0.3 units higher than the control. The SGR w of juvenile abalone obtained in this present study is slightly higher than in previous studies by Bansemer et al (2015) or Harris, Burke, Edwards and Johns (2005), although the differences might also be due to the different initial sizes of abalone (Table 3).…”

This study is aimed at the isolation and screening of alginate lyase‐producing bacteria from the gastrointestinal tracts of hybrid abalone, Haliotis rubra x H. laevigata, as probiotic candidates. Six bacterial isolates were detected to produce alginate lyase. Of these, the isolate with the highest alginate‐lyase activity was identified as Enterobacter ludwigii strain EN‐119, displaying 99% similarity of 16S rDNA sequence. Further assays indicated that E. ludwigii showed good viability and stability when it was incorporated into manufactured pellets and stored at 4°C for 7 days. The isolate also had high tolerance of high salinity (35 mg/L), low pH in simulated stomach juice (5) and to simulated intestinal juice containing surfactants such as bile salts and gastric enzymes (pepsin and trypsin). Additionally, a short, preliminary study indicated that supplementation of E. ludwigii via manufactured pellets improved the total weight gain and specific growth rate of hybrid abalone. These results suggest that E. ludwigii is a potential probiont for shortening the culture period of hybrid abalone.

“…Significance for all analyses was set at P b 0.05. Survival rate was arcsine transformed before analyses (Bansemer et al, 2015). Differences in shell length and survival among the experimental lines and heterosis were analyzed by multiple comparisons of means using a One-Way ANOVA.…”

“…Generally, within the optimal temperature range, feed intake of greenlip abalone increases with an increase in water temperature. Nevertheless, it declines when water temperature is beyond this range as abalone may be under thermal stress (Bansemer et al., 2015; Lange et al., 2014; Stone et al., 2013, 2014). According to Stone et al.…”

“…Lin, Lin, and Huang (2009) also reported that skin colour change in 10‐day‐old juvenile seahorses ( Hippocampu erectus ) differed significantly among three different temperatures, 23, 26 and 29°C. In abalone, the influence of water temperature on growth, survival, food intake, metabolism and reproduction are well documented (Bansemer et al., 2015; Grubert & Ritar, 2004; Harris et al, 2005; Lange, Currie, Howarth, & Stone, 2014; Moss, 1998; Stone et al., 2013, 2014), but there are no published reports on the effect of temperature on the colour of abalone. We, thus, hypothesised that temperature can affect abalone colour as it governs dietary pigment intake, absorption and digestion.…”

In Australia, commercially farmed greenlip abalone (Haliotis laevigata Donovan), fed formulated diets display a faint lip and dark foot colour in comparison with wild abalone. This study evaluates the impact of macroalgal diets and water temperatures on the colour and tissue pigment deposition in farmed greenlip abalone. Three diets are (a) fresh Ulva sp., (b) a commercial diet and (c) a formulated diet of 30% of dried Ulva sp. meal supplement were used to feed 3‐year‐old greenlip abalone at either 22 or 26°C for 38 days. Abalone fed 30% dried Ulva sp. meal supplement had significantly higher the shell colour saturation than those fed fresh Ulva sp. The lip colour was deeper in abalone fed fresh Ulva sp. and was significantly more pronounced than those fed the diet containing 30% Ulva sp. meal. Abalone at 22°C had a significantly higher lip colour saturation value than those at 26°C. The foot of abalone fed fresh Ulva sp. was light gold, whereas abalone fed the 30% Ulva sp. meal or the commercial diet had a dark brown foot at 22°C. The foot colour was paler in abalone at 26°C than at 22°C. The content of β‐carotene was significantly higher in abalone fed fresh Ulva sp. than those fed the other diets. Abalone contained a higher amount of β‐carotene at 22°C than at 26°C. This study indicates that high water temperatures make foot colour paler and the fresh Ulva sp. diet can make the foot colour lighter at 22°C.
