Abstract:
The effects of temperature and oxygen tension (P-O2) on the rate of oxygen consumption of three different Spanish strains of Artemia have been studied. Adults from each strain were able to tolerate acute exposure of temperature up to 35 degrees. No differences were found between the oxygen consumption rate of males and females of the bisexual strain. The oxygen consumption rate increased with increasing temperature; Q(10) values varied between 1.82 and 2.04 for the three strains. The effect of temperature on oxygen consumption rate was less in the parthenogenetic tetraploid strain than in the diploid strains (B, PD), which showed the lowest oxygen consumption rate values. The ability of the adults to maintain respiratory independence during hypoxia was reduced at high temperatures. The differences in oxygen consumption rate between tetraploid and diploid strains correlate well with the bio-geographical distribution of the three autochthonous Artemia strains of Spain.
