“…By contrast, the wild‐caught amberjack juveniles contained taurine at 19–21 mg/g dry matter, and the smallest‐sized juveniles (28–44 mm TL) contained 21.0 mg/g dry matter. A similar trend is also reported in cultured larvae and juveniles and wild juveniles of yellowtail 32 . The high taurine content in the wild juveniles is attributable to the high taurine contents of their foods.…”

“…Wild yellowtail larvae and juveniles consume mainly copepods and cladocerans until 80 mm TL and then shift their foods to fish larvae and juveniles 33 . Although the wild zooplankton samples in the present study and in Matsunari et al 32 . were not the exact foods consumed by the wild juveniles examined, the taurine contents were equivalent to or higher than that of Artemia nauplii.…”

To improve the nutritional quality of live foods and dry feeds ordinarily used for the seed production of amberjack Seriola dumerili, the nutrient contents of rotifers, Artemia nauplii and commercial feeds used in two larval production stations were evaluated. For comparison of the nutrient contents, artificially produced larvae, wild-caught juveniles and wild zooplankton samples were also analyzed. The proportions of 22:6n-3 in the polar lipid of the cultured larvae increased by feeding the dry feeds. The taurine contents of the cultured larvae reflected the contents of their foods (rotifers < dry feed < Artemia nauplii). The taurine content and the proportion of 22:6n-3 in Acartia spp. were higher than in foods fed to the larvae. These parameters in the wild juveniles were higher than the cultured ones. The A/E ratios [(each essential amino acid/total essential amino acids) ¥ 1000] of the total amino acids of the live foods and dry feeds were similar to those of the cultured larvae, except for the lower ratios of histidine, arginine, threonine and lysine in the live foods. The mucosal folds of the intestine of the cultured larvae did not show typical signs of dietary phospholipid deficiency. These results suggest that requirements of nutrients such as 22:6n-3 and taurine should be determined for mass production of amberjack seeds.

“…8 Previous research has shown that the amount of taurine in yellowtail is affected by dietary taurine content. 9 In addition, juvenile yellowtail fed diets H Matsunari et al supplemented with taurine showed improved growth, and taurine content of the whole body increased proportionally with the increase in dietary taurine level. 10 So far no experiment has been conducted to investigate the influence of taurine in broodstock diet on the reproductive performance of yellowtail.…”

The effect of dietary taurine was investigated on reproductive performance in yellowtail Seriola quinqueradiata. Two-year-old fish of average body weight 6.1 kg were fed on diets containing three levels of taurine (T-0, T-0.5 or T-1.0%) for 5 months prior to spawning. For spawning investigations, fish were induced to maturity by human chorionic gonadotropin injection (600 IU/kg-fish) and artificially inseminated. Oocyte growth improved significantly (P < 0.05) with the increase of dietary taurine. The collection of eggs from females reared on the T-0% diet was not successful. The success rate of spawning for females fed on T-0.5 and 1.0% diets was one out of six, and six out of seven, respectively. The taurine levels of the liver and serum in the T-0% diet group were much lower than that in the T-0.5 and T-1.0% diet groups (P < 0.05). Fish fed the T-0% diet showed higher contents of serine in the liver and serum. The taurine content of the ovary was not significantly different among the different dietary treatments. These results indicate that taurine has a positive effect on the improvement of spawning performance of yellowtail.

“…Since rotifer contain only a trace amount of taurine (\1 mg/g dry weight), a rapid decrease in taurine content in the fish body is observed in the hatched larvae of yellowtail, a similar trend to that observed for DHA. When taurine content was measured in hatchery yellowtail larvae and juveniles grown to a body size of up to 18 cm and in wild yellowtail larvae from 3 to 18 cm, wild larvae contained a taurine concentration 2-4 and 2 times (15 mg/g) higher than hatchery larvae, respectively; this appeared to be because wild larvae fed on taurine-rich organisms such as natural plankton (12 mg/g) and crustaceans (20-30 mg/g) [84]. With the aim of preventing a decrease in taurine content in the fish body, Takahashi et al [85] attempted to enrich rotifers with taurine.…”

Progress on larval and juvenile nutrition to improve the quality and health of seawater fish: a review

In seedling production of seawater fish, providing appropriate nutrition is a necessity for successful production of quality larvae and juveniles. Mass-produced live prey organisms, such as the rotifer Brachionus plicatilis species complex and brine shrimp Artemia spp., alone do not provide sufficient nutrition to the larvae and juveniles of seawater animals. This inadequacy has led to various problems related to fish quality and health, including increased incidence of morphological and behavioral abnormalities and mass mortalities. It is, therefore, important to identify the factors associated with these problems to improve seedling production techniques. This review collates the efforts made during the past two decades in larval nutrition-focusing on advances made in the use of certain nutrients, such as docosahexaenoic acid, vitamin A derivatives, and taurine that are important for the mass production of seawater fish larvae and juveniles-with an aim to improve the quality and health of fish.
