According to the theory of the size of breeding stock in order to protect the reproductive chances of each individual should be given at least once. To achieve this, the length of the stock on the effective hunting tool, the first sexual maturity should not catch small individuals. This is what gear a look from the lenght opening of the first sexual maturity, and even small individuals couldn't catch basically raises questions of how to measure mesh opening. Gear mesh size measurement tools and methods used till now and is stil continuing developments on this issue. What are these tools and methods used in this study, compiled from the advantages and disadvantages relative to eachother. Looking at the historical process, the first instrument used to measure mesh opening wedge (wedgegauge) that can be said. According to measurements, this can not differ from person to person, and due to the need to use a constant force, the practical difficulties of this instrument has always been rendered moot. However, the availability of easy to use and practicality ensures that the meter is stil the most common. Wedges have been developed following the ICES (The International Council for the Exploration of the Sea) gear mesh size of the gear mesh size measuring gauge gun. This tool is from person to person, depending on the measurement values as a general solution to the problem of changes in routes help the fishing industry is not wide spread. In addition to the absence of a Standard calibration procedure, the time an authentic international not won. The most recently developed gear in the OMEGA mesh gauge (objective mesh gauge). Eliminate the disadvantages of the other two even though the meter is not legal to use only there commended level.
