Abstract
The study was carried out to determine the suitable stocking densities and harvesting methods, and to evaluate the economic efficiency of Artemia biomass culturing in tarpaulin tanks in Ho Chi Minh City. The experiment consisted of 8 treatments arranged in a completely randomized block design with 3 replicates of 2 stocking densities (M1: 1,500 & M2: 2,000 individuals/L) and 4 harvesting frequencies (T1: 1 day/time - 10%, T3: 3 days/time - 30%, T5: 5 days/time - 50% and T14: 14 days collecting 100% amount of Artemia biomass in the tank). The study results showed that the average size of males and females ranged from 9.12 - 9.55 mm and 9.84 - 11.01 mm, respectively. At day 14, the survival rate at a density of 1,500 individuals/L accounted for 63.68 ± 2.50% which was statistically significant (P < 0.05) compared to the density of 2,000 individuals/L (60.95 ± 1.39%). The mean fecundity of female Artemia ranged from 70 to 72 embryos/female and tended to increase gradually from 92 to 101 embryos/female. The harvesting frequency affected Artemia population composition, density and biomass yield. After 29 days, the T3M1 treatment yielded the highest biomass (3.33 ± 0.39 kg/m3) and the most optimal profit with 225.53 ± 9.08 thousand VND/kg. The treatment DCM2 gave the lowest yield (1,22 ± 0.27 kg/m3) with a profit of 78.04 ± 58.58 thousand VND/kg.
