“…The values for survival were higher (73%-74%) than in our previous study (52%-54%; Anh et al 2009). This result is comparable to data obtained in laboratory experiments, e.g., MaldonadoMontiel and Rodríguez-Canché (2005) achieved 79% survival after 15 d of culture, feeding rice bran and Tetraselmis suecica.…”

“…In contrast to the results for single variables, the combination of different green water types and supplementary feeds had a significant effect on growth performance (length and weight) over 14 d. The range of mean length (9.2-9.5 mm) and individual wet weight (9.1-9.5 mg) in the present experiment were comparable with the results obtained in our previous research work (Anh et al 2009). …”

“…Culture of Artemia in the salt ponds was managed according to Anh et al (2009). Initially, the water level in the Artemia ponds was about 4-5 cm above the platform (about 35 cm in the peripheral ditch) and then gradually increased up to 40 cm during the culture period.…”

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.

“…The total lipid of A. tunisiana, Borg El Arab, and El Mex strain (≈ 12.59-14%) resembled another Artemia sp. (9-13%) studied by Anh et al (2009). Triantaphyllidis et al (1995) and Han et al (2000) established that the lipid composition of hatched nauplii is not affected by diet or environmental conditions.…”

Background: Comparative analysis of essential amino acids and fatty acid of enriched and unenriched Artemia spp. collected from Wadi El Natrun, Elbeheira, Egypt, was investigated. Results: The obtained results indicated that Leucine recorded the highest concentration (17.22%, 11.4%) in unenrichment A. tunisiana and A. franciscana, respectively followed by arginine (10.31%, 9.6%); however, glutamic acid recorded the lowest concentration (0.05%) in A. tunisiana. Statistical analysis showed no significant differences in some amino acid concentrations (P < 0.001) in both A. tunisiana and A. franciscana as arginine, valine, proline, and aspartic acid. Other amino acids were highly significantly fluctuated as glycine, leucine, histidine, phenylalanine, glutamic, and tyrosine; they were high in A. franciscana. Aspartic acid was significantly higher in unenrichment nauplii. Regarding the comparison between A. franciscana and enrichment A. tunisiana, the data showed non-significant improvement for the majority of the recorded amino acids. The analysis of unsaturated fatty acids n-3 and n-6 families after 18 and 24 h of enrichment Artemia was achieved. The composition of unsaturated fatty acids was significantly increased after enrichment to 79.7 mg/g DW instead of 46.5 in newly hatched nauplii. Saturated fatty acids were also significantly increased from 20 to 25.28 mg/g DW. The enrichment process was significant (P < 0.001) in nauplii enriched with fatty acids for 18 h. The more pronounced effect of duration was the amount of energy as it was 33.17 kJ/g after 18 h, while it was 45.693 kJ/g after 24 h incubation. The ratio of ascorbic acid, due to Artemia enrichment by vitamin C for 24 h, was increased from 853 to 3227 μg/g dry weight after enrichment. Conclusion: To conclude, enrichment with cod liver oil and vitamin C obviously affected the chemical composition of local Egyptian Artemia (A. tunisiana).

“…Harvesting of good-quality cyst product requires collection of recently produced cyst batches from the open water shortly followed by adequate processing, but these conditions are seldom fulfilled, especially when harvesting natural production in inland lakes, when site accessibility is limited, timing of harvesting is irregular, transport and storage is an issue, and/or overall expertise is lacking. In Artemia pond production, such as in the Mekong Delta, Vietnam, frequent harvesting (up to 2-3 times a day) followed by adequate processing is currently done, which contributes to the good quality of the resulting cyst product (Anh et al 2009). …”

Hatching and nutritional quality of Artemia cysts progressively deteriorates as a function of increased exposure to hydration/dehydration cycles

Nauplii hatching from Artemia cysts are crucial in larviculture nutrition. Artemia cysts may be exposed to repeated hydration/dehydration (H/D) cycles pre-harvesting or during processing and storage. To observe the effect of these cycles on cyst quality, Artemia franciscana cysts were exposed to a comprehensive set of various H/D treatments, differing in the number of cycles (1, 2, or 3) and the duration of the freshwater hydration period (2 or 4 h). Cyst quality was assessed using the criteria of immediate relevance for aquaculture use, such as hatching percentage directly after H/D treatment and after -18°C storage up to 1 month, longevity of axenically hatched starved nauplii, cyst and naupliar energy content, and (for the most extreme H/D treatment) cyst and naupliar fatty acid and vitamin C content. Repeated H/D cycles resulted in significantly (P \ 0.05) decreased cyst hatching, reduced starved naupliar longevity and individual energy content, loss in vitamin C and fatty acid content, and moreover a close correlation between these parameters as a function of progressive H/D treatments. This is of immediate relevance for aquaculture nutrition, as commercial Artemia cysts may have gone through an unknown sequence of H/D cycles in nature or in the processing line, which affects the nutritional quality of the nauplii used in larviculture operations.
