On-growing production, sea cage farms
An on-growing farm bases its production on buying fry or juvenile fish and producing fish ready for slaughtering. An inexpensive system for on-growing production is to use cages, in lakes, calm rivers or in the sea.
A total sea cage farm includes the following components (Fig. 21.25):
· The cage farm with fixed equipment
· An operations base
· A boat
· Net handling equipment.
The cage farm includes the cages with the mooring system. Equipment fixed to the cage can be feeding equipment, equipment for collection of dead fish and feed loss, and a lighting system.
