Objectives of the Course
The overall goal of this course is to provide theoretical knowledge and practical training in fishing gear design and construction techniques. A holistic view is taken of fishing technology. The act of fishing is viewed as the an integrated process where due consideration must be taken of the design and materials used to produce the fishing gear, fishing gear, the biology and behaviour of the fish being caught, fish schools and finally the environmental conditions on the fishing grounds. In this course, the students will learn how to seek solutions to many problems which arise in the activities of a fisherman, fishing technologists, fishery managers by apply some theoretical and practical ways.
