Testimonials

    

To me,FMST is the ideal place to study about the Marine Sciences in Sri Lanka.FMST helped me grow and excel as a student,all the while nurturing my love for the ocean, backed by some of the best academics in this field.



S K Edirisinghe
    

Being selected as a student of FMST is the major turning point in my life. Within the premises of FMST, I was provided with myriads of opportunities to explore new horizons and to build up my personality. This is the perfect place to grab the knowledge about Fisheries and Marine Sciences. All academics & extracurricular activities not only widened my knowledge, but also heightened my passion for my future career.
