盐度对不同卤虫品系存活和生殖性能的影响
Effect of salinity on survival and reproductive performance of different Artemia strains
摘要
Abstract
This paper investigated the effect of salinity (70, 125 and 180, respectively) on survival and reproductive performance of autochthonous Artemia parthenogenetica from Bohai Bay saltworks, China (BHB) and A. franciscana obtained from the saltponds of San Francisco Bay, USA (SFB) and artificially-produced from Vinh Chau, Vietnam (VSFB). The results indicated that, within the experimental salinity range, the survival rate of all tested Artemia strains declined significantly as salinity rising. The SFB and VSFB had a better tolerance to higher salinity than BHB. Higher salinity resulted in significantly longer maturation period and brood interval for BHB, while no significant effect was observed on SFB and VSFB. The nauplii and cysts yield per brood of all tested strains tended to reduce along with salinity increasing. At lower salinity (70), BHB dominantly produced nauplii, VSFB produced more nauplii than cysts, and SFB produced more cysts than nauplii. In contrast, at higher salinity (125 and 180), VSFB dominantly produced nauplii, and SFB and BHB produced more nauplii than cysts. In con-clusion, our data provided evidence that VSFB had a better survival rate and dominant ovoviviparous reproduction at higher salinity compared to local BHB and SFB,, and thus are more adapted to the environmental conditions in salt ponds and may be a more effective colonizer in saltworks.关键词
