ABSTRACT:
A net pen or cage for containing aquatic animals. The pen has a light-weight inexpensive net cover for the top which keeps predators out. The cover is easy to apply and remove and yet is held securely in place by means of studs or posts extending upwardly from the frame of the cage or pen and having enlarged heads which preferably are slightly larger than the holes in the mesh. Preferably the mesh is made up of resilient plastic strands which snap back into their original shape after being deformed by the bolt-heads passing through, so that the bolt heads and the netting together form a snap-fitting fastening system. In one embodiment, panels of materials such plastic netting are suspended in cages so as to attract the growth of algae thereon for feeding algae-eating aquatic animals such as conch, fish, etc. in the cages. The panels are formed into a removable unit so that some of the units and can be suspended in water elsewhere and transferred to the cage to replace units from which the algae has been depleted, thus feeding the aquatic animals by merely replacing algae-depleted units with algae-loaded units.
