The fluorine enrichment mechanics of antarctic krill Ⅰ. The fluorine chemical formation

The different formal fluorine in different parts of molting process of krill were analyzed by culture of antarctic krill(E. Superba). The results show that fluorine amount in cuticle is up to 90%, of total in the krill. During the krill molting process, the fluorine content in curicle and muscle vary alternatively. This is, the fluorine content in new cuticle and muscle is very lower after molted, the fluorine in krill comes from seawater by biological absorbed of the krill, and the absorbed fluorine by krill lost with the old cuticle at the end stage of molting process. Measwhile, the new molting process starts again. At the last the authors propose the fluorine enriching process model of antarctic krill.
