A study evaluated the effectiveness of the three week 1969 University of British Columbia technical fisheries short course in terms of knowledge gain and changing attitudes (especially toward regulatory agencies) during the course. Program content stressed scientific, rather than vocational, aspects of fisheries. Data on 22 adult students of the 1969 class (Group I) were obtained with six objective instruments and subjective discussion session. Two of these--a socioeconomic instrument and a knowledge and attitudes test--were given to 40 nonstudents (Group II) and 55 former students (Group III). Group I fishermen preferred vocationally oriented subjects, but indicated an interest in and understanding of academic and research oriented content. They felt that the subject content met their needs. Attitudinal, knowledge, and socioeconomic data showed that Group I fishermen were more representative of Group III than of Group II, and that no significant differences existed between knowledge scores of former students and Group I posttest scores. On the basis of these and other findings, it was concluded that the 1969 short courses was a success, but that certain modifications in content, instruction, and format would have enhanced its effectiveness.
