Abstract:
The reproductive behavior of two populations of Artemia is analyzed, one from San Quintin, Baja California, and the other from Yavaros, Sonora. In the interpopulation mating, alternating oviparous and ovoviviparous reproduction was observed, with the former dominating. In the San Quintin intrapopulation crossbreeding, 100% oviparous reproduction was observed. The intrapopulation fertility of Artemia from San Quintin was 75% and from Yavaros, 82.35%. In the interpopulation femaleYav/maleSQ crossbreeding, fertility was 73.3%, and in the femaleSQ/maleYav crossbreeding, 66%. It is concluded from these experiences that the population from San Quintin is Artemia franciscana, although some delay was observed in the mating time with the Yavaros population, which suggests the beginning of a specific differentiation.
