There are various types of fish farming all around the world. The aquaculture process is in which the farmers raise the fish in enclosures such as Dock fish cage and sell them off for food. Fish farmers tend to grow varieties of fish, and there are various fish farms containing salmon, tilapia, cod, catfish, and others.
Aquaculture is also known as pisciculture. It is referred to the process in which the nurturing organisms practice is done to increase productivity. Let us tell you all about different types of fish farming.
Simple Guide To Fish Farming
Fish farming is known to be the primary aquaculture form. It is the cultivation of the fish for commercial purposes in tanks and other types of enclosures or cages. The most common fishes farmed are the catfish, salmon, carp, cod, and trout.
Mariculture is amongst the activities which involves food production for human consumption. This process is the cultivation of water species such as fish, shellfish for food.
For instance, FinFish, sea plants, shellfish, etc., are cultured in saltwater. There are products for agriculture that are used for cosmetics, jewelry such as pearls and fish meals.
The process of agriculture is the agriculture type that lives in algae. Harvested algae are the microalgae, or the macroalgae, usually known as the seaweed. While macroalgae come with various uses for various commercial purposes, the cultivation and the size make them difficult to grow. And the microalgae are easier to harvest on a large scale.
Types Of Methods And Systems
There are different fish farming systems, and the farmers choose to use one method or several simultaneously. There are primarily two types of aquaculture: extensive fish farming based on local photosynthetic production and intensive fish farming. In this farming type, the farmers feed the fish with the external supply of the food.
Let us understand more deeply about these types of fish farming methods.
Extensive Fish Farming
The primary examples of the extensive system are the pond or the irrigation ditch system. The significant feature of this system will be installed in the semi-natural environment along with the natural supply of food to the cultured fish.
The farmers will be able to regulate the pond’s background with various species and special equipment. In these types of farming methods, there is a need to remove the old and dirty water and add the new water. For this, the swing check valve manufacturer is the most integral part.
The extensive fish farming system is based on the semi-natural atmosphere, such as the existing ponds, natural foods for fish in the culture such as algae, zooplankton, and crustaceans.
The food production within the extensive system can be increased with the help of fertilizing the pond, which is usually done with the help of animal waste. The natural balance in this system will be maintained with the support of stocking the ponds with different types of fish occupying the different ecological niches.
Species such as tilapia, which feeds on the algae, catfish feeding on the pond bed, and carp feast on the zooplankton, need food to survive.
It is better to keep taking care not to overstock the ponds or the excessive amount of the fertilizers, which can potentially cause algal blooms and oxygen depletion, which can cause significant loss to the farmer and the failure of fish lives.
Intensive Fish Farming
This system is executed in closed-circulation tanks or flowing through the raceways. However, there are various floating sea cages in this system open to the natural environment. In methods such as these, the farmers control the water, oxygen, and food supply quality.
The closed tanks for circulation come with sophisticated water purification systems. It is a costly fish farming process, but the good thing is that the production rates are also higher and offset the outlay.
There is an increased risk of diseases in this method due to the stocking density and the high degree of monitoring. Experience is an integral part of running the intensive system successfully in this process.
This method leverages the external food supply such as pallets, corn, soy, and feather to feed the predatory fish. The population is high, the usage of antibiotics will also be increased, and the wastage of the food is also high, along with the high sewage output in this farming method.
The quality of the water is highly critical and needs a solid purification system if the farm is in a closed system such as a ditch, tank, or pond.
Fish farming is an integral part of the seafood industry as it helps to minimize the risk of overfishing which can potentially put the fish at the risk of getting extinct. Fish farming can drastically reduce the chances of fish extinction. If you are in the seafood industry, you should work with YoonPak and use paper packaging to reduce water pollution.
