“…have been utilized only in fertilizers and animal feeds (Kang, 1968). Furthermore, the growth rate of juvenile abalone was reportedly higher upon addition of a mixture of U. pinnatifida and S. horneri in comparison with either single treatment alone (Ansary et al, 2019). These observations, together with our findings regarding feeding preference toward S. horneri, suggest that it can be used as an abalone feed substitute.…”

The Pacific abalone, Haliotis discus hannai, is a highly valued and industrially important aquaculture species with growing demands of the expanding abalone aquaculture industry. To explore the feasibility of using the brown alga, Sargassum horneri, as a potential substitute for abalone feed, it is important to identify the feed preference and attractant effect of S. horneri on Pacific abalone. Our experiments indicated that the feeding-associated movement of abalone could be detected using a video tracking system under indirect illumination with dim red light. To further analyze the attraction potentials of various test materials, preference analysis was performed using Avicel-coated glass plates with ground powders of various seaweeds (e.g., S. horneri, Saccharina japonica, and Undaria pinnatifida) and commercial abalone feed, together with coffee waste. Heat map analysis indicated greater attraction by the kelp S. japonica than by S. horneri and commercial feed, which showed similar preference levels. Feeding preference based on the area of Avicel eaten by abalone showed a significant preference for U. pinnatifida over S. horneri (feeding area: 68.6 ± 20.1% vs. 37.5 ± 22.4%, p < 0.05). Additionally, the feeding area was significantly greater for plates with S. japonica than for plates with S. horneri (44.0 ± 16.6% vs. 22.6 ± 15.4%, p < 0.05). There was no significant difference in feeding area between commercial feed and S. horneri (31.7 ± 11.6% vs. 31.6 ± 20.2%, p > 0.05). The methanol extracts attracted abalone in the following order: U. pinnatifida > S. horneri > S. japonica > commercial feed > coffee waste. To determine the attractive effects of the components of methanol extracts, mixtures of methanol extracts of commercial feed with increasing amounts of S. horneri were examined. The results showed a significant increase in feeding preference upon addition of S. horneri up to 50% and 75%, suggesting its potential for use as an appetite-enhancing feed additive. This study identified conditions that can be successfully used to monitor the movement of Pacific abalone; the results of preference analysis confirmed that abalone exhibited similar attraction and feeding preference for S. horneri, compared with commercial feed.

“…Relatively high cumulative mortality of sea cucumber fed the Con diet at the end of the 96‐h post observation after both the 30‐h air exposure and 12‐h low salinity exposures indicated that sea cucumber fed the diets treated by sulphur regardless of sulphur type and concentration seemed to more capable to resist both air and low salinity exposure stressors. Similarly, aquatic animals, such as fish and molluscs fed nutritionally balanced diets, have higher capacity to survive against abiotic stressors compared with those fed nutritionally unbalanced diets (Ansary, Baek, et al, 2019; Ansary, Jeong, et al, 2019; Duan et al, 2016; Lee et al, 2016; Liu et al, 2015).…”

“…japonicus ) tolerates salinity fluctuations when inhabiting the intertidal zone and culturing ponds, it can survive within 22–38 psu, but 30–32 psu for the optimum salinity, respectively (Bai et al, 2015). Scientists reported that improvement in nutrition status of diet could lead to better resistance capacity of aquatic animals against different abiotic stressors (Ansary, Baek, et al, 2019; Ansary, Jeong, et al, 2019; Lee et al, 2016; Liu et al, 2015). Therefore, it is necessary to develop nutritionally rich diet to improve health status of sea cucumber against common abiotic stressors, salinity and air exposure stressors.…”

Supplementation effect of sulphur type and concentration on survival, growth and stress resistance of sea cucumber has not been known. Two‐way {2 type sulphur [liquid type (LTS) and nano‐powder type (NTS)] ×5 sulphur concentrations (25, 50, 100, 250 and 500 ppm)} ANOVA design was applied. LTS and NTS were included in the control (Con) diet at five sulphur concentrations instead of equal amount of water and cellulose, referred to as the LTS25, LTS50, LTS100, LTS250 and LTS500, and NTS25, NTS50, NTS100, NTS250 and NTS500 diets, respectively. Sea cucumbers were fed with triplicate groups of each diet for 8 weeks. After 8‐week feeding trial, sea cucumbers were exposed to 30‐h air and 12‐h low salinity exposure stressors and cumulative mortality was monitored. Survival was not affected by either sulphur type or sulphur concentration. Weight gain of sea cucumber was affected by both sulphur type and concentration. Sea cucumber fed all NTS diets except for the NTS25 diet achieved better weight gain than that fed the Con and all LTS diets. Chemical composition of sea cucumber was not affected by either dietary sulphur type or sulphur concentration. The cumulative mortality of sea cucumber was affected by both sulphur type and concentration after the 30‐h air and 12‐h low salinity exposure stressors. In conclusion, NTS was more effective than LTS to improve growth and lower mortality of sea cucumber subjected to the 30‐h air and 12‐h low salinity exposures. The greatest weight gain and resistance were obtained in sea cucumber fed the NTS500 diet.

“…In addition, protein (amino acid [AA]) and lipid (fatty acids [FA]) content of these MA do not satisfy the requirements of abalone (Mai, Mercer, & Donlon, , ; Uki, Sugiura, & Watanabe, ). The poor growth performance of abalone fed a single MA, U. pinnatifida (Ansary, Baek, et al, ; Ansary et al, , ; Baek et al, ; Choi et al, ; Jang et al, ) or S. japonica (Garcia‐esquivel & Felbeck, ; Jung et al, ; Myung et al, ) compared to a nutrition‐balanced diet has been reported. Since these MA are one of the most expensive ($US 3–4/kg) feed components in formulating commercial abalone diet (Jang et al, ) and their market prices have recently increased sharply due to high demand for expanded abalone aquaculture and human consumption, development of alternative source for MA is highly needed in abalone feed.…”

Growth performance and the soft body composition of juvenile abalone fed the extruded pellets (EPs) substituting fish meal (FM) and macroalgae (MA) with tunic meal of sea squirt (SS) was investigated. A total of 1,260 abalone were distributed into 18 containers. Six experimental diets were prepared in triplicate. Five diets were pelletized by an extruder pelleter. The 140 g/kg FM and 250 g/kg mixture of MA were included into the control (Con) diet. Five hundred and 1,000 g/kg of each FM and MA were substituted with an equal amount of tunic meal of SS, referred to as the FM50, FM0, MA50 and MA0 diets, respectively. Finally, dry Undaria pinnatifida was prepared. Weight gain and specific growth rate of abalone fed all EPs were greater than those fed U. pinnatifida. Weight gain of abalone fed MA50 and FM50 diets was greater than Con and FM0 diets, but not different from MA0 diet. Higher crude protein and lipid contents were observed in soft body of abalone fed all EPs compared to U. pinnatifida. In conclusion, FM and MA up to 500 and 1,000 g/kg, respectively, could be replaced with tunic meal of SS in EPs without retardation in growth of abalone.
