Nowadays, consumption of fisheries products is increasing. There are several factors, one of which is a quantitative development through aquaculture. Another factor is an increase qualitative consumption of fish which require that fish be supplied the live. This is required a lot of technical effort to transport the live fish that have low survival rate(c.f. tuna and mackerel) in coastal waters and the open sea.
In this study, the research for the development of the towing cage system for transporting the live fish was tested in simulation.
The cage system is designed by using a computer tool. The tension and spread performance of the cage system were measured. The simulations were conducted with 30 degrees angle of kite and towing speeds of 1.0 to 3.0 knots at 0.5 knots intervals.
The results of simulations were as follows;
1. In order to vertical spread, floats attached at the upper part of the cage, and iron chains attached at the lower part of the cage. For horizontal spread, canvas kites attached on the both side of the cage.
2. The tension of the cage was tended to increase with increased towing speeds.
3. The reduction ratio of inside volume of the cage was tend to increase with increased towing speeds.
4. The suitable operation condition in towing cage system was 2 knot towing speeds wih vertical spreading force 885kgf, horizontal spreading force 567kgf; in this case the ratio of the inside volume reduction of the cage was estimated as 25%.
