Course content
An introduction is given to the methods traditionally used to investigate exploited aquatic organisms. This includes laboratory methods for determination of population parameters, and field work for direct estimation of fish density. The concept of a fishery model is introduced. We adapt this theory to widely diverse species and international fisheries, and make simple quantitative predictions of the suitability of different exploitation regimes. Harvest technology deals with a general description of the vessel and gear technology used in different parts of the world. We deal with fish behavior, types of materials, operation methods, selectivity, and fish detection and density estimation with hydro-acoustics. New developments in the pursuit of energy efficient and environmentally friendly gear, as by-catch reduction, and user friendly gear, will be addressed.
Objectives of the course
This is an introductory course designed to level the knowledge of the students on aquatic biology and technology, irrespective of their academic background. The student becomes acquainted with different fishing methods and drilled on the basic field techniques, analytical tools, vocabulary and advice given by fishery scientists. This facilitates their participation in multi-disciplinary teams dealing with natural resources. The course is also a requirement for later courses on ecological assessment and population management. In addition to experience fieldwork and fishing, students rehearse some general research methods and skills.Recommended reading/syllabus
