Introduction

The set of fifty-two lectures covered by TPI Reports G144 and G145 has been prepared for a course lasting approximately eight weeks. The course is designed for people at middle-management level in both Government and Industry. Government staff would include Fisheries Officers and Senior Extension Workers who have a fisheries background and degree level qualifications.

Each lecture session would normally last for about 45 minutes, although some might be expanded to provide two such sessions. Much depends on the linguistic competence of the lecturers and participants and also on the students' level of understanding of basic science. The course should include many practical and demonstration sessions to illustrate the theoretical considerations presented here. In general terms one half of the course time could be devoted to lecture sessions and one half to practice and observation. Extensive use of overhead projector, blackboard, colour transparencies and films is recommended. A list of films suitable for showing during the course is appended.
