The relationship between in situ target strength and depth of chub mackerel was established by selecting the length composition of mackerel was larger than 90%. Results showed that the in situ target strength of chub mackerel was changed significantly depend on depth up to 8.7 dB. And it indicated that the measurement of in situ target strength of fish with swim bladder should be modified by the relationship of target strength and depth, especially in chub mackerel, it may be led to overestimate the standing crop to 7.4 times of the assessment.

And this paper also shows the structure and parameters of the optical system. The Xenon light of super high voltage is used as interferential source. The position of it is on the focus of the reflector of ellipsoid surface. After reflecting, its lights form a collective point . This point and objective focus of collimation lens are superposition. Though the collimation lens, the beam of light become parallel lights. Then though the Coude Reflector and radiation system of special prism, the lights become a beam of light with 3 ° emanative angle.
