The carbon metabolism of two marine sponges, Haliclona oculata and Dysidea avara, has been studied using a 13 C isotope pulse-chase approach. Ecology: Skeltonema subsalsum is a fresh to brackish water species, usually occurring in salinities up to 15‰ in rivers, lakes, inland seas, coastal waters, and marshes, and often associated with eutrophic conditions (Clarke 1995, Gibson et al. The purpose of the study is to determine the effect of Skeletonema costatum as a natural food for survival (survival rate) of Artemia salina. The genus Skeletonema was established by R.K. Greville in 1865 for a single species, S. barbadense, found in the Barbados deposit [Jung 2009]. A phytoplankton growth model was then developed for investigation of Skeletonema annual abundance pattern regulating mechanisms. S. costatum Zingone & Sarno (sensu stricto) (Yamada et al.
