“…Consequently, determination of maximal harvesting rates of Artemia is complicated, which makes accurate sampling and accurate population estimates very difficult (Wear & Haslett 1987). Moreover, measurement of Artemia productivity is time consuming, requiring population dynamic and biometric data, which are often difficult to gather (Barata, Hontoria & Amat 1996).…”

The e¡ect of partial harvest strategies on the production of Artemia biomass was evaluated for 12 weeks under Vietnamese salt farm conditions. The initial stocking density was 100 nauplii L À 1 . After 3 weeks of inoculation, Artemia adults were partially harvested at intervals of 1, 3, 6 and 9 days starting with an initial quantity of 30 kg ha À 1 day À 1 at ¢rst harvest, and then the quantity of harvestable biomass was adjusted according to the standing stock present in the culture pond, combined with the time needed to harvest these quantities and with the weight of biomass harvested in each pond. The results showed that in most cases, the total densities were not significantly di¡erent among harvesting frequencies (P40.05). However, a relatively higher Artemia adult density and its standing stock were better maintained in the 3-day than in the 1-day interval, and were signi¢cantly higher compared with the other two harvesting frequencies. The total biomass yields were the highest (1587 kg ha À 1 ) in the 3-day harvesting interval, followed by 1-, 6-and 9-day harvesting interludes, corresponding to 1323, 1091 and 975 kg ha À 1 respectively. However, no statistical difference was observed between the 1-and the 3-day interval as well as between the 6-and the 9-day harvest schemes (P40.05). The results of this study suggest that partial harvest of Artemia biomass performed every 3 days appears to be an appropriate strategy to enhance biomass productivity.Values with di¡erent letters (a^c) in a row are signi¢cantly di¡erent (Po0.05). The numbers within parenthesis indicate the degree of freedom (d.f.) between groups and within groups respectively.

“…In Artemia production manuals, many efforts have made to help to choose suitable species/populations to be applied in aquaculture industry (Tackaert & Sorgeloos, 1991；Lavens & Sorgeloos, 1991Barata, Hontoria, & Amat, 1996;Thi, Van, & Sorgeloos, 2013). Additionally, the effect of environmental parameters was studied on potential of cyst production (Barata et al, 1996;Thi et al, 2013；Gao, Wang, Ma, Stappen, & Sui, 2017Nguyen, 2015;Thi, Pachecovega, Cadenaroa, Ascencio, Rangeldávalos, & Rojascontreras, 2015).…”

The quality of Artemia cysts size can be determined by biometrical characterization. In this study, the combined effects of salinity and ferric citrate were studied on the biometric characterization of Artemia by single clonal reproduction under the laboratory condition. Results of control treatment showed increasing of the salinity correlates non-significant with diameter of decapsulated cyst and negatively correlates with the size of untreated cyst and chorion thickness. The effect of low concentrations of ferric citrate (5 and 10 mg/L) led to release the largest cysts in low salinity (35 ppt), while in high concentrations of ferric (20 and 40 mg/L) the largest cyst was released in medium salinity (70 ppt).

“…Thus, cyst and nauplii size estimates in the Sfax solar saltern, especially from ponds M2 and M3, in addition the high DHA/EPA ratios (1-3.3) are of great importance in view of considering Artemia as a potential feed source for early larval stages of fish and/or shrimp. The maximum size of males (7.7 mm, pond M3) and females (8.7 mm, pond B1) of A. salina in the Sfax solar saltern were smaller than that found by Barata et al (1996) for the same species in Spain (male: 9.96 mm; female: 12.11 mm). We found a strong inter-pond variation in cyst dimensions (table I).…”

“…Biovolumes of cysts (from 15 measurements in each case) were calculated using simple geometric shapes and then converted to fresh weight (FW) biomass in accordance with Lohman's (1908) calculation technique. The biomass of adults was calculated using the equation: W = 0.00082 Lt 3.14 or W = 0.0018 Lt 2.73 for males and females, respectively (Barata et al, 1996), where Lt (mm): adult body length; and W (μg): adult dry weight. Brine shrimp biomass was expressed as mg dry weight (DW) brine shrimp per liter of water.…”

We investigated the correspondence of the seasonal patterns of Artemia salina with several environmental factors along a natural salinity gradient in four ponds (M1, M2, M3, and B1) located in the arid solar saltern of Sfax (southern Tunisia). The shape of the frontal knobs of males showed the dominance of the autochthonous species, A. salina. Artemia abundance and fecundity were assessed. Biometrics of A. salina stages were studied by comparing cyst size and body length. A. salina abundance displayed a clear seasonal and spatial variation. Abundance of live Artemia ranged between 0.25 × 10 3 and 1414 × 10 3 ind m −3 . The highest numbers were recorded in pond M3, as nauplii (771.8×10 3 ind m −3 corresponding to 31.8 g m −3 ). This resulted from low male and female numbers (34 and 17 × 10 3 ind m −3 , respectively). Artemia cysts were predominant (92.96% of total Artemia), and grouped in small (216 μm) and large (243 μm) sized cysts, which correlated negatively with temperature (r = −0.4, N = 294, p < 0.01) and salinity (r = −0.39, N = 294, p < 0.01), and positively with female fecundity (r = 0.6, p < 0.05). The large (270 μm) and small (216 μm) cysts suggested the presence of also the species A. parthenogenetica and A. franciscana in the saltern, respectively. Fecundity showed a summer-autumn distribution that correlated significantly (−0.6 and −0.9, N = 35, p < 0.01) with both temperature and salinity. A. salina performed best in M2 (more than 80 cysts per brood), at about 200 g l −1 and 26.8 • C, with gravid females representing 20%. A. salina from the Sfax solar saltern was unable to withstand extreme temperatures (35 • C), but tolerated extreme salinity (330 g l −1 ). Abundance, biometrics, and reproductive descriptors of A. salina appeared to be governed chiefly by temperature and salinity, the physical structure of the saltern, and food availability, such as the unicellular green alga, Dunaliella salina. Nauplii (mean length: 401 μm) from small-sized cysts encountered in the saltern might be a valuable food source for hatcheries of some small-mouthed marine fish. RÉSUMÉ La distribution spatio-temporelle d'Artemia salina couplée aux facteurs environnementaux a été étudiée dans quatre bassins de salinité croissante M1, M2, M3 et B1 de la saline de Sfax (Sud de Tunisie). La forme du lobe frontal des mâles d'Artemia montre la dominance de l'espèce autochtone A. salina. L'abondance, la fécondité et la biométrie des différents stades d'Artemia ont été estimées en comparant le diamètre des cystes et les longueurs des autres stades. L'abondance d'A. salina montre une nette variation spatio-temporelle. La densité d'Artemia varie entre 0,25×10 3 et 1,4×10 6 ind m −3 . La plus forte valeur est enregistrée au niveau du bassin M3, où les nauplii représentent 7,71 × 10 5 ind m −3 correspondant à une biomasse de l'ordre de 31,8 g m −3 . Par contre, le nombre des mâles et des femelles est faible avec 34 et 17 × 10 3 ind m −3 , respectivement. Les cystes d'Artemia prédominent (92,9% de l'abondance total), et ils sont repré...
