Study on the Fishing Gear and Method of Shrimp, Trachypenaeus curvirostris(STIMPSON)

In order to develop an effective fishing gear and method for shrimp, Trachypenaeus curvirostis(STIMPSON) which is largely distributed in the western coastal waters of Korea, we made a newly designed experimental fishing gear and a series of fishing operations was carried out in the fishing ground near the Gogunsan Is. from April to November 1983, and evaluated the fishing efficiency of the gear. The results are as follows; I. Catch per unit length(m) of fIoat line is O.24kg for the B type of net which is the best in fishing efficiency and O.19kg in average catch of the three different nets. 2. Catch tends to increase according to the current velocity, and is especially high in 1.1-1.2k'ts in every fishing operation. 3. The highest value of catches with respect to the drift time of the net is shown at 30 minutes of drift when the current velocity is below 1.1~1.2k'ts. While the current velocity is above 1.2k'ts, the catch varies with respect to the driftage of the net(current velocity X drift time); the highest value of catch appeared at O.55~0.60 miles of drift.
