摘要
Dominance and survival strategy of toxic dinoflagellate Alexandrium tamarense and A. catenella under the dissolved inorganic nitrogen (DIN) limited conditions were examined in the laboratory and field observations. In Masan Bay, DIN was limiting factor for growth of phytoplankton during spring to early summer when Alexandrium spp. have been observed. They have a disadvantageous position compared with diatoms because Ks of nitrate calculated from growth kinetics experiment of A. tamarense and A. catenella was higher than diatoms. However, A. tamarense and A. catenella were able to grow using dissolved organic nitrogen (DON) compounds such as urea and amino acids as well as DIN. Therefore, DON utilization of A. tamarense, A. catenella might contribute to not only their population growth but also dominance and interspecific competition in the DIN-limited conditions in Masan Bay.

在实验室和现场观察中检查了在溶解的无机氮（DIN）限制条件下毒性甲藻塔玛亚历山大藻和链霉菌的优势和存活策略。在马山湾，当亚历山大藻属（Alexandrium spp。）时，DIN限制了春季至初夏浮游植物生长的因素。已被观察到。与硅藻相比，它们具有不利的位置，因为根据塔玛亚历山大藻和猫科动物的生长动力学实验计算的硝酸盐的Ks高于硅藻。然而，A。tamarense和A. catenella能够使用溶解的有机氮（DON）化合物（如尿素和氨基酸以及DIN）生长。因此，在马山湾的DIN限制条件下，利用A. tamarense，A。catenella可能不仅有助于其种群增长，而且还有助于优势和种间竞争。
