Quality evaluation tests were done on the strain of Artemia Las Cumaraguas, Paraguaná, Venezuela, in terms of cyst and naupliar (Instar 1) biometrics, as well as percentage, efficiency, rate and productivity of hatching. Bi-monthly sampling of cysts was carried out from January to September 1991. Simultaneously. temperature and salinity were measured. Average hydrated cyst diameter was 238.14 µm (s.d. ± 0.012). Average length of the nauplii (Instar 1) was 438.69 µm (s.d. ± 0.028) and average chorion thickness 1 1.36 µm (s.d. ± 0.012). Average hatching percentage and efficiency were 81.25% (s.d. ± 3.27) and 203.505 naupliiig (s.d. ± 20.95), respectively. As to hatching rate, T90 was observed at 24.14 hours and the hatching synchrony was obtained at 10.7 hours. Hatching productivity ranged from 184.3 to 354.53 mg/g of cysts. Results reveal the potentiality of Artemia from Las Cumaraguas and its possible use in aquaculture.
