Development of circular floating cages for milkfish broodstock at the SEAFDEC Aquaculture Department.

摘要

The present attempt to develop floating cages for holding milkfish, Chanos chanos, broodstock at SEAFDEC was prompted by the need of the department to have more fish for experimentation. This paper briefly presents the departments experience in developing the cage culture system designed for holding milkfish for broodstock purposes. The following points are discussed: (1) site location; (2) biological factors; (3) floats; (4) netting; (5) framework; (6) layout and mooring; (7) maintenance; (8) cost. Designs are given for the net cage cover, frame and floats.
