Practical and Rapid Diagnosis of Fish Population
MetadataShow full item record
Problem of population analysis have been increasing year by year. This is attributed, on the one hand, to the programs of exploitation of fish resources having been carried out so successfully that the use of data processing is now required and, on the other, to the management of fisheries in the world having become very important not only to conserve marine resources at the optimum level, but also to deal scientifically with international fisheries problems. Moreover, stock assessment should be carried out as soon as possible. The scientific echo sounder is one technique for quick assessment. However, whereas by the use of the scientific echo sounder, population size is estimated quickly, diagnosis of population status cannot be obtained.
