Later, to enable the students to get expertis in the field of fisheries biology, M.F.Sc degree programme in Fisheries Biology [M.F.Sc (Fisheries Biology)] was introduced during 1990. Following the ICAR guidelines, the degree was renamed as M.F.Sc (Fisheries Resource Management) in 2011 and since then M.F.Sc. degree program is offered in Fisheries Resource Management. The following ten courses (7 major + 3 minor) are offered under semester system for M.F.Sc.

Details of Courses

The doctoral programme (Ph.D) in Fisheries Biology and Capture Fisheries was started during 1989. The title was renamed as Fisheries Resource Management during 2011 and since then, Ph.D is offered as Fisheries Resource Management. The following seven courses (5 major + 2 minor) are offered under semester system for Ph.D.
