内容説明

This manual, a title in the "FAO Fishing Manual" series, provides an explanation of general calculation principles, design procedures and test methods to enable fishing gear designers and technologists, teachers and fishermen to solve problems in design, research and fishing operations. It avoids higher mathematics and succeeds in simplifying description of complex design and testing procedures. The knowledge here imparted can help to refine existing gear methods and introduce new ones to the benefit of fisheries in developed and undeveloped countries.

目次

  • Part 1 Theory: the theory of fishing gear and fishing systems
  • netting geometry and the nature of internal forces
  • external forces acting on fishing gear
  • methods for calculating fishing gear as a system of flexible lines
  • model tests of fishing gear. Part 2 Design: general principles of designing commercial fishing gear
  • designing trawls
  • designing purse seines
  • designing gill nets.
