(2) Popularly called Gurnards, Lepidotrigla microptera, form dense schools in the SouthernYellow Sea in winter, and these schools do not migrate to the lower latitude than 32°30′N.
(3) Body length composition was in the range of 9.6-29.6cm and the most abandantly capt-ured individuals measured 13.0-27.0cm in length. Average body length of the female was 19.78±3.24cm, and that of the male was 19.78±2.185cm. The male amount to 56.67% of the whole.
(4) Relation between body length and weight was represented as follows:
w=1.7186L^0.250l
(5) Relation of weight between body and ovary was represented as follows:
EW=0.000006324 BW²⁷⁰¹
Average number of incubation was 140, 000, and diameter of ovum was comparatively sm-all being less than 0.8mm.
(6) In the fishing season body length was various according to depth. Schools of big gurnards have a tendency to travel in deep water and small ones in shallow.
(7) The proper depth for catch was in the range of 65-70m, and the best depth for catch was 69m. And composition of body length of the fish caught in the depth of 65-70m were 20. 10±2.408cm.
(8) Quantative variation of catch according to age of the moon was found. (Fig. 7). Kindsand quantity of bait were also changeable. (Fig. 8).
