“…Since these features all lower the postenrichment DHA:EPA ratio in Artemia, optimal enrichment diets must have very high DHA and low EPA levels. Compared with oil emulsions, 24 h feeding on algae results in a relatively slight HUFA increase, and the DHA:EPA ratio remains low, even though it corresponds to microalgal fatty acid composition (Thinh et al 1999). Thus, algal enrichment is sometimes performed (mainly with Isochrysis), but oil emulsion enrichment is generally preferred.…”

“…Factors such as cyst strain, temperature, and food conversion efficiency strongly influence biomass production in proportion to initial nauplii density (Sorgeloos 1980). Young Artemia are n-3 HUFA deficient (Thinh et al 1999;Vismara et al 2003) and an issue with its enrichment is the retroconversion of DHA into EPA, occurring particularly in younger individuals (Navarro et al 1999). Therefore, the nutritional value of adult Artemia is superior to that of nauplii or young stages (Léger et al 1986).…”

Ongrowing and enhancement of n-3 HUFA profile in adult Artemia: short- vs long-time enrichment

The use of adult Artemia is uncommon in aquaculture and limited to feeding adults of species not accepting inert diets. The aim of the present study was the development of a standardized technique for adult Artemia production in small volumes (25-100 L), and the assessment of ongrowing and enrichment diets for enhancement of n-3 highly unsaturated fatty acid (HUFA) content. We firstly assessed the effect of initial nauplii density (1, 2, and 3 nauplii mL −1 ) and food dose (x1, x2, and x3 quantities of mixed Tisochrysis lutea, Spirulina, and Prolon) for production of Artemia. Intermediate nauplii densities and food doses yielded the best overall results (44-46% survival; 5.6-5.9-mm length; 365-456 μg Artemia −1 ). Secondly, four diets (mixtures of Tisochrysis lutea, Phaeodactylum tricornutum, Spirulina sp., Prolon, and Red Pepper) were tested for ongrowing. Ten short-time enrichments (STEs; 30 h) and a long-time enrichment (LTE; 9 days) were also assayed for n-3 HUFA (Highly unsaturated fatty acids) enhancement. The improvement in n-3 HUFA was rather limited in STE. However, LTE on a mixture of P. tricornutum, Prolon, and Red Pepper (regardless of further STE) in ongrowing Artemia yielded the highest contents in total fatty acids and in 20:4n-6 20:5n-3, 22:5n-3, and 22:6n-3. The quality of LTE Artemia was based on an equilibrated dietary source of protein (Spirulina), 20:5n-3 (P. tricornutum), and 22:6n-3 (Red Pepper). STE Artemia had a quality similar or even higher than that of captured zooplankton, and its use in our laboratory for the feeding of seahorses significantly enhanced breeding and newborn quality.

We evaluated the combined effects of different green water sources and feed supplements on Artemia biomass production and economic efficiency. A two-factor experiment was set up with two green water types produced from the ratios of nitrogen and phosphorus (N:P = 5 and N:P = 10) in combination with two types of supplemental feed (rice bran or pig manure). After 12 weeks of culture, total Artemia biomass yield with the N:P = 5 treatment (2.29 ton ha −1 crop −1 ) was 14% higher than that with the N:P = 10 treatment (1.97 ton ha −1 crop −1 ), although this difference was not significant (P > 0.05). There was no significant interaction between green water and supplemental feeding treatments for the final yield of Artemia biomass. Comparative cost-benefit analysis showed that the treatment of N:P = 5 combined with pig manure attained a significantly higher net profit and cost/benefit ratio than the other treatments.
