“…These reports indicated that the growth of sea cucumbers was not only very slow, but also significantly different among individuals. The weight gain of sea cucumbers ranged from 30.82 to 48.20% in this study, which was similar to that of Xia et al () who found that the weight gain ranged from 31.30 to 45.89% with similar initial body weights (about 5 g), similar experimental duration (56 or 60 d), and similar experimental environment. However, other studies (Zhang et al ; Zhao et al ) found that the weight gain of sea cucumbers exceeded 100% under similar conditions (initial body weight [about 5 g], similar experimental duration [56 or 60 d], and similar experimental environment).…”

Taurine has been widely used as a growth‐ or health‐promoting additive in aquatic animals because of its multiple functions, while little work has been done on its effects on sea cucumbers, in spite of the occurrence of serious diseases. In this study, juvenile sea cucumbers (4.68 ± 0.04 g) were fed diets supplemented with taurine at 0% (control), 0.1, 0.25, 0.5, 1, and 2% for 8 wk. At the end of an 8‐wk feeding trial, growth performance of sea cucumbers was not significantly affected by dietary taurine (P > 0.05). However, dietary taurine significantly elevated intestinal lipase activities of sea cucumbers (P < 0.05). Intestinal amylase activity and trypsin activity in sea cucumbers did not show significant changes after animals were fed diets supplemented with taurine (P > 0.05). Dietary taurine at all five dosages significantly increased total antioxidant capacity in sea cucumbers, while superoxide dismutase activity in groups with dietary taurine at 0.25 and 0.5% was significantly higher than that of the control group (P < 0.05). Therefore, it appears that taurine could be used as a potential feed additive to confer better health of farmed sea cucumbers.

This feeding trial was conducted to determine the vitamin E requirement of growing sea cucumber Apostichopus japonicus Selenka. Six isonitrogenous and isoenergetic experimental diets were formulated to contain graded levels of vitamin E (6.7, 81.2, 159.3, 237.8, 314.6, 395.9 mg/kg diet). Each diet was assigned randomly to 30 growing sea cucumber with initial body weight 15.43 g in triplicates for 8 weeks. Survival rate was not affected by dietary vitamin E; meanwhile, both the weight gain (WG) and specific growth rate were presented the trend of increasing first and then kept stable. With the increasing of dietary vitamin E, crude lipid content of body wall was evaluated firstly and dropped afterwards. When dietary vitamin E contents were lower than 159.3 mg/kg, vitamin E contents of body wall were increased by dietary vitamin E levels, but there were no more differences when dietary vitamin E higher than 159.3 mg/kg. There were minor effects on digestive enzymes of intestine by dietary vitamin E. Contents of malondialdehyde were decreased, while the total superoxide dismutase activity was increased first and then decreased with the increasing of dietary vitamin E. Activities of intestinal alkaline phosphatase were increased, and glutamic oxaloacetic transaminase were decreased first and then increased with the increasing of dietary vitamin E. In conclusion, analysis by a linear regression equation of WG or vitamin E contents in body wall indicated that the optimum requirement of vitamin E for growing sea cucumber (initial body weight 15.43 g) was 165.2-187.2 mg/kg diet.

“…Sea cucumber generally requires a relatively low energy supply for optimum growth (Sun et al 2004, Zhu et al 2005. Stable isotope analysis can effectively yield valuable information on the incorporation of micro-and macronutrients (Le Vay & Gamboa-Delgado 2011, MartinPerez et al 2013, Xia et al 2015b. In the present study, we compared the discrepancies of growth, protein turnover and energy budget of green and white sea cucumber under different dietary regimes, to provide scientific basis for further study on the physiological ecology and nutriology of sea cucumber.…”

A 98 d experiment was conducted to compare the growth performance, protein turnover and energy budget between green and white color morphs of the sea cucumber Apostichopus japonicus. During the experiment, sea cucumbers were fed a single natural diet of Sargassum thunbergii and a premixed artificial diet. Results showed that there was no significant interaction of diet, species or experimental time on growth performance and feed utilization of A. japonicus. Specific growth rate (SGR) of green sea cucumber was significantly higher than that of white sea cucumber. Green sea cucumber fed S. thunbergii exhibited much higher food conversion efficiency (FCE) and protein efficiency ratio (PER) compared to those on the artificial diet, indicating preferential absorption of S. thunbergii. There were also significant discrepancies in body wall production rate (BWPR), crude protein and ash content between green and white sea cucumber. The observed δ 15 N values gradually increased owing to the assimilation of the diets containing higher nitrogen stable isotope ratios. Green sea cucumber reflected and approached δ 15 N values of the experimental diets much more quickly and with shorter half-lives than white sea cucumber. The relatively constant metabolic contributions in intestine (71 to 78%) and body wall (46 to 52%) of sea cucumber indicated a stable bioenergetic distribution strategy of tissue. According to the time-based turnover model, the estimated fractionation (Δ 15 N) ranged from 2.37 to 3.30 ‰. The average formulas of energy allocation for green and white sea cucumber were: 100C = 7.8G + 53.1F + 6.2U + 32.8R, 100C = 6.3G + 57.9F + 8.9U + 27.0R, respectively. Taken together, our results suggest that white sea cucumber may have higher dietary quality requirements for growth and metabolism than green sea cucumber.KEY WORDS: Apostichopus japonicus · Growth · Nitrogen stable isotope · Protein turnover · Energy allocation OPEN PEN ACCESS CCESSA comparative study on growth, protein turnover and energy budget of green and white color morphs of sea cucumber Apostichopus japonicus (Selenka)
