Most of our customers order ocean fish cage shipment. Compared with air delivery, there are a few advantages via ocean shipment. Firstly, ocean shipment can carry as much as 10 times volume cargos. If you order ten sets of complete cages, for example, you can receive all of them just once instead of several bills for air. Secondarily and importantly, ocean shipment is much cheaper than air delivery, if you are not in a hurry.
