| Abstract |
The aim of this study was to investigate if the productive but high-temperature adapted Anemia franciscana (Kellogg, 1906) strain from Vietnam can be used in the biological management of the more temperate conditions of the Bohai Bay salt ponds, P.R. China. For this purpose, the effect of culture temperature (14, 25 and 33 degrees C) and feeding level (100, 50 and 25% of optimal feeding level) on survival, length, and reproductive traits of the autochthonous parthenogenetic Anemia from Bohai Bay, China (BHB), bisexual A. franciscana originating from San Francisco Bay, CA, U.S.A. (SFB) and Vinh Chau A. franciscana from Vietnam (VCSFB), were tested. Survival rates of the three populations were not significantly affected by the feeding level at each culture temperature (P > 0.05). At higher temperature the survival of the two bisexual populations was better than that of the parthenogenetic population. On the other hand, the length of Anemia was significantly affected by the feeding level at each culture temperature and higher feeding levels resulted in greater length (P < 0.05). No reproduction occurred in any strain at 14 degrees C. At 25 degrees C, reproductive traits were significantly affected by the feeding level. The bisexual populations produced more offspring than parthenogenetic Anemia. SFB Anemia tended towards oviparity, whilst VSSFB and BHB produced more natiplii. At 33 degrees C, all strains produced less offspring and tended to produce more nauplii than cysts. Our data provide evidence that, compared to the local parthenogenetic Anemia, the high-temperature adapted Anemia strain from Vietnam may be a more effective colonizer of the temperate Bohai Bay saltworks. |
