①Connecting Spread를 일정하게 하고 Towing Line의 길이를 변화시킬 때 각 속도에 따른 망고 및 망폭 Towing line의 길이가 길어질수록 망고는 높아지고 망폭은 좁아진다. ② Towing line의 길이를 일정하게 하고 Connecting Spread를 변화시킬 때 망고 및 망폭은 Connecting Spread가 넓어질 수록 망폭은 넓어지나 망고는 거의 변화가 없다.

영어 초록

A scale model net test of the operation of a small two-boat midwater trawl net was performed in the circulating water tank at Pusan Fisheries College. The 1/32 scale model net was constructed after the modelling law of M. Tauti. This type of net is used in Europe for catching sprat like Hering. The net used was 1/32 the actual size. This scale was chosen with consideration for the water tank size. In this experiment, the transfomation of the net shape was observed especially inregard to variations in the height and breadth of the net mouth. These dimensions were varied by changing the breadth of the towing line and the connenting spread.
