Objectives of the Course
Some indicator values are used in fishing gears to compare and to improve new designs. Performance and efficiency are the most common parameters. In addition, physical characteristics of synthetic fibrils in gears which are made of netting twine and mesh openings should be suitable when designed a fishing gear. For this reason, importance of measuring on the fishing gear related the above topics and also evaluation of the values and interpretation of the results are aimed to teach in this course. In addition, properties of device used in measuring and measuring technique or methods are also discussed. Possible effects of the fishing gear when designed or improved to the close environment are also take in to account in the course extent.
