F. Correasandoval et al., THE GROWTH-RATES OF 4 POPULATIONS OF ARTEMIA-FRANCISCANA (ANOSTRACA, ARTEMIIDAE), Revista de biologia tropical, 42(3), 1994, pp. 605-609
The growth rates of three populations of Artemia franciscana from Mexi
co (one from Yavaros, Sonora and two from San Jose, Baja California) a
nd that of the reference strain from San Francisco Bay, California, gr
own under the same laboratory conditions, were not statistically diffe
rent, either considering total mean increase in length, or increase by
stages. However, interpopulational differences were detected in the f
inal length of some developmental stages. In addition, regressive chan
ges of dimensions were noted in some populations at the time of stage
change. These might be the result of inborn characteristics of each st
rain, causing each population of Artemia franciscana to respond, in ph
ysiological terms, in different ways to the same environmental conditi
ons.
