Abstract
This study investigated and compared the linkage activities of 75 scientists from both universities based and nonuniversity based aquacultural research institutes. The study showed that scientists from both universities based
and non-university based aquacultural research institutes were male dominated, 70% and 97%. University based
scientists had high Ph.D, studying for higher degrees and job tenure of ten years (56.7%, and 73.3%).
Communication method mostly used by university based scientists was seminar 23%, while non-university based
scientists used Research Extension Farmer Input Linkage (REFIL) (97.7%) and personal contact (86.7%). The
paper suggests that efforts of government should be geared towards activities that may promote linkage activities
of both categories of scientists.
