Identifikasi Genus Chaetoceros di Perairan Laut Desa Padelegan Pamekasan
Chaetoceros sp. merupakan fitoplankton yang banyak ditemukan di perairan laut. Chaetoceros termasuk dalam kelompok Diatom dengan kelas Bacillariophyceae. Di laut spesies ini merupakan makanan alami dari Copepoda, salah satu spesies zooplankton. Sedangkan pada budidaya perikanan digunakan sebagai pakan alami Rotifer dan larva udang. Selain itu, spesies chaetoceros termasuk dalam kelompok saprobe yang berperan sebagai indikator biologis perairan yang tercemar sehingga keberadaannya di laut cukup penting.

期刊介绍:
The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
