Comparative analysis between Artemia parthenogenetica and Artemia franciscana size from China, Vietnam and United States of America Sources

Abstract

Artemia, also known as brine shrimp, are important organisms in the aquaculture industry due to their ability to adapt to high salinity environments and high nutritional value, making them suitable live food for various aquatic species. Our research is focused on two distinct species of Artemia franciscana and Artemia parthenogenetica from various geographical regions. Because of the current demand, Artemia is the preferred the choice for small-sized live feed for aquatic larvae. Hence, it is crucial to choose suitable artemia sources that correspond with the dietary requirements of aquatic larvae. The results were significantly differed between the species, suggesting potential for optimizing specific strains tailored to distinct aquaculture applications. The findings revealed notable disparities across the species, suggesting the possibility of enhancing certain strains customized for specific aquaculture purposes. The sizes of cysts and the Instar I stage in Artemia franciscana from Vietnam were 31.7 ± 7.25 μm smaller than those of A. franciscana from United States of America and A. parthenogenetica from China. The gathered statistics provided preliminary criteria for choosing strains that are well-suited size of live feed to certain aquaculture hatcheries.
