III. MANUSCRIPT VERIFICATION AND FORMAT: The manuscript submitted to Vietnam Journal of Marine Science and Technology must not have been published before. This manuscript has not been reviewed for publication in another journal. The publication must be approved by all authors. If accepted, it will not be published elsewhere in the same form, in English or in any other language (including electronic file which the author receives).
