Cage culture principle matters – two types that everyone should know

Cage culture principle is very important when people are farming fish. In this blog, we are going to reveal the basic cage culture principle and introduce two main cage types.

Fish production is very close to temperature and dissolved oxygen in the water. In static ponds, the amount of fish breeding limits due to limited oxygen in the water. The amount of restocking cannot be too large. In flowing water, the dissolved oxygen increase as well as the stocking amount. Cage culture is a high-density intensive farming method.

cage culture principle

1. Filter type cage culture
Fish, such as silver carp and other species, will swim through the water and filter plankton. Thus, the stocking density cannot be too high. Even if the stocking density is as large as 20 times to pond culture, there will no be the problem. As long as plankton in the water, the silver carps can be replenished continuously. Meanwhile, the water can bring in the dissolved oxygen. And it can bring out the metabolites produced by fishes as well. As long as plankton exists, it can get quite high output.

2. Feeding type cage culture
Traditional aquaculture cannot solve the dependency between stocking density, water quality and bait. This usually leads to high stocking density and high oxygen consumption for livings. The metabolites cannot be discharged in time. And the water quality of the aquaculture system deteriorates easily. It will destroy the high yield, high efficiency and healthy aquaculture. But cage culture is a good way to resolve these contradictions and get a higher yield. The good living environment in the cage promotes the digestion and use of feed. And it reduces the feed coefficient. Cultured stockings can only move in a small area. This will improve mutual food and energy consumption. It increases nutrition accumulation and ensures healthy products.
