“…However, upon the commencement of feeding posthatch, the Artemia diet becomes the major factor influencing biochemical composition and can be markedly influenced by enrichment protocols (Merchie et al 1995a). AA has previously been delivered to prey items via Artemia nauplii using AP/lipid emulsions (Merchie et al 1995a) or algal enrichment (Dhont et al 1991;Naegel 1999). During our study, we demonstrated that A2P, like AP (Merchie et al 1995a), was quickly assimilated by a range of Artemia sizes as the active form of AA, which is readily available to predator larvae .…”

“…Water-stable forms of AA are now available including a number of ascorbyl polyphosphate (ApP) derivatives used in pellet feeds, and ascorbyl palmitate (AP), an additive used in lipid enrichment emulsions for live larval feeds (Merchie et al 1995a). Enrichment of Artemia with microalgae can also provide the benefits of increased endogenous AA levels (Dhont et al 1991;Naegel 1999;Ritar et al 2003).…”

A study was conducted to establish whether a particulate form of ascorbic acid (AA), ascorbyl‐2‐phosphate (A2P), could be used to enrich Artemia. In the first experiment, we examined the efficiency of A2P conversion to and maintenance of AA by juvenile Artemia (1.5 mm, 5‐day‐old) held at 9000 L−1 and 28 °C for 24 h. Maximal uptake and assimilation was >10 000 μg AA g−1 dry weight (dw) (representing >1%Artemia dw) at enrichment rates of ≥1.2 g A2P L−1. In the second experiment, a similar biomass of instar II/III nauplii (1 mm, 2‐day‐old) and juvenile (2.5 mm, 8‐day‐old) Artemia were enriched for 6 or 24 h at 28 °C before starvation for 6 or 24 h at 18 or 28 °C. At 0 h and after 6 and 24 h enrichment, AA levels were 485, 3468 and 11 080 μg g−1 dw in nauplii and 122, 4286 and 12 470 μg g−1 dw in juveniles. When Artemia nauplii or juveniles were enriched for 6 h and starved for 6 h at 18 or 28 °C, there was no significant reduction in AA. Continuation of starvation to 24 h at 18 and 28 °C reduced the level of AA to 3367 and 2482 μg g−1 dw in nauplii and 3068 and 2286 μg g−1 dw in juveniles. After 24 h enrichment, 6 h of starvation at 18 and 28 °C reduced AA to 8847 and 7899 μg g−1 dw in nauplii and to 9053 and 8199 μg g−1 dw in juveniles. Continuation of starvation to 24 h at 18 and 28 °C further reduced AA levels in nauplii to 6977 and 4078 μg g−1 dw and to 7583 and 5114 μg g−1 dw in juveniles. This study demonstrated that A2P could be assimilated as AA in the body tissue of different‐sized Artemia in a dose‐dependant manner and AA was depleted during starvation depending on time and temperature.

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.

In the 1980s, Artemia franciscana from San Francisco Bay (SFB) was introduced into Kenyan saltworks, where it has colonized and established stable populations. However, little is known about its biology, particularly with respect to its parental SFB population. This study compared the salinity tolerances of Kenyan (KEN) population, their SFB progenitors and those of Great Salt Lake (GSL) populations. Growth and survival of these A. franciscana populations were evaluated under varying salinity levels in a laboratory set up. A. franciscana nauplii were cultured at a rate of 1 nauplii/mL in 36 Erlenmeyer flasks and fed microalgae (Chaetoceros sp.) at 1.5 × 106 cells/animal/day for 8 days. Survival was evaluated daily and survivors were fixed in individual vials with Lugol solution. The total length of each fixed A. franciscana nauplii specimen was measured under a compound microscope. All populations were susceptible to salinities greater than 100 g/L. Compared with the parental SFB population, the KEN population exhibited significantly reduced survival and growth at 140 g/L, suggesting a narrower salinity tolerance range. These findings underscore the need for further studies focusing on other physiological parameters, abiotic factors and genetic characterization to confirm whether the KEN population is experiencing ecological adaptation. This will contribute to the optimization of Artemia practices in various salinity environments as a result of climate change.
