“…Thus, the phytoplankton derived nutrients and inhibitory factors are taken indirectly via consumption of foods, primarily rotifers ( Artemia nauplii also cannot digest Chlorella and Nannochloropsis ) (Sick ). The extent of phytoplankton nutrient uptake by rotifers is primarily influenced by the enrichment environment before they are introduced into the larval rearing tanks (Kobayashi, Nagase, Hino & Takeuchi ; Dan & Hamasaki ; Matsunari, Hashimoto, Oda, Masuda, Imaizumi, Teruya, Furuita, Yamamoto, Hamada & Mushiake ) and by the species and concentration of phytoplankton that are supplemented into the larval rearing tanks (Reitan, Rainuzzo, Øie & Olsen ; Dan & Koiso ; Hamasaki et al . ).…”

Because these enriching and supplementing factors varied among seed production trials (Dan et al 2013), we speculate that this explains the variation in megalopal morphology that was observed among trials during P. trituberculatus seed production.…”

The occurrence of morphologically immature megalopae, which retain zoeal features such as dorsal spines and furcae of telson, is closely correlated with larval mass mortality during seed production of the swimming crab Portunus trituberculatus in Japanese hatcheries. To determine the cause of immature megalopal morphology, zoeae were reared with various supplementary schedules and density of diets (rotifer, Artemia and phytoplanktons including Chlorella vulgaris and Nannochloropsis oculata). In addition, to assess the relationship between immature morphology and endocrine control, the effect of causative dietary factor was compared with the effect of eyestalk ablation at various timing during zoeal development. Megalopal immature morphology was more distinct in Chlorella‐supplemented groups than in Nannochloropsis‐supplemented groups. High density Chlorella supplementation was associated with the highest incidence of immaturity and resulted in larval mass mortality. The premoult of the third zoeal stage was identified as a critical period at which Chlorella supplementation led to the highest incidence of immaturity. This critical period coincided with the critical period at which larval metamorphosis was regulated by the eyestalk neurosecretory system. Our results suggested that the occurrence of immature megalopal morphology under culture conditions is most likely caused by phytoplankton (especially, Chlorella) supplementation, which disrupts the endocrine regulation. On the basis of our results, we successfully prevented the occurrence of immature megalopal morphology in 500 L tanks by excluding the influence of phytoplankton before the critical period (i.e. discontinuing phytoplankton supplementation and supplying rotifer cultured with non‐phytoplankton materials).

“…from the first feeding, followed by the use of brine shrimp (Artemia sp. nauplii and meta nauplii) appropriately enriched with commercial or experimental products to finally cofeed during the weaning stages until complete replacement of live feed at later stages [5][6][7][8][9][10][11]. Thus, hatchery-reared juveniles are usually characterized by the high number of weak fish with low resistance to manipulation at early stages [10], high size variability, and high incidence of skeleton anomalies in comparison to the wild-captured ones [11].…”

Most commercial products available for Artemia sp. enrichment include high levels of docosahexaenoic acid (DHA) to boost its nutritional value, though with limited success. In this regard, the present study evaluated the alternative utilization of eicosapentaenoic acid (20 : 5n-3; EPA) oils to improve the n-3 long-chain highly unsaturated fatty acid content (n-3 LC-HUFA) in enriched Artemia sp. to feed greater amberjack (Seriola dumerili) larvae. Five experimental emulsions containing increasing levels of EPA from 0.8% to 60% of total fatty acids (TFA) and n-3 LC-HUFA (1.3%–70.6% TFA) were formulated. Each diet was fed to greater amberjack larvae (17–35 days posthatch (dph)) in three replicate 200-L tanks. The dietary EPA supplementation significantly improved larval growth during the feeding trial and survival at 35 dph ( P < 0.05 ). In addition, larval fatty acid profiles showed a positive correlation with dietary EPA. Finally, despite the sum of total skeletal anomalies and column anomalies were not significantly affected by dietary EPA, increasing dietary EPA, and n-3 LC-HUFA tended to reduce the incidence of these types of anomalies in greater amberjack larvae at 35 dph. Based on these results, S. dumerili larvae could be successfully grown with low DHA but high EPA-rich oil enrichment products when n-3 LC-HUFA content in Artemia sp. is maintained in sufficient amounts.
