| Research Abstract |
This study aims to develop methods to evaluate food qualities of fresh fish by using high frequency ultrasonic imaging techniques. Internal organs of walleye Pollock, cod, salmon and sturgeon were observed by using 3MHz and 5MHz ultrasonic. Results showed that can identify female from male individuals. Also it can estimate sizes of individual eggs in gonad resulted to evaluate maturity. The ultrasonic images of internal organs get clearer along with increase of ultrasonic frequency.
