CATDOLL : CATDOLL: What is the traditional fish farming model?

1. What is the traditional fish farming model?

1. Modern aquaculture is called facility fishery. 2. Facility fishery is an intensive and high-density breeding industry developed in the mid-20th century. It integrates modern engineering, electromechanical, biology, environmental protection, feed science and other disciplines. It uses various latest scientific and technological means to create good water and environmental conditions suitable for fish growth and reproduction on land or at sea, put fish farming under artificial control, and use scientific intensive breeding technology to achieve stable and high yields of fish throughout the year. Its industrial forms are mainly: factory breeding, large water body circulation breeding, cage (net enclosure, net fence) and other net breeding. Because it is based on environmental protection and closely combines industry and environment, it has broad development prospects.

2. Four models of fish farming?

Including: open breeding, intensive breeding, circulation breeding and isolated breeding. 1. Open breeding is to release fish directly into natural waters. Due to the large water space and natural breeding environment, fish can grow and reproduce freely. This model has the advantages of low cost and abundant resources, but it is also susceptible to restrictions and losses in the natural environment. 2. Intensive breeding is in a closed water body, where fish are concentrated in a small area and the growth of fish is managed and promoted through factors such as artificial feeding and water quality control. This model can efficiently utilize limited feed and water resources, and is conducive to monitoring and controlling the spread of diseases during the breeding process, but there may be problems such as environmental pollution and fish competition. 3. Circulation breeding is to combine water quality treatment technology to complete fish breeding and water recycling within a certain range. Through biological filtration and water flow treatment systems, water quality is kept clean, wastewater discharge is reduced, and breeding efficiency and environmental sustainability are improved. 4. Isolated breeding is to keep fish in closed facilities, completely isolated from the external environment. By controlling factors such as temperature, humidity, and oxygen, a suitable breeding environment is created to improve growth efficiency and quality stability. This model is suitable for the breeding of special fish species, but the cost of facility construction and maintenance is relatively high. In summary, the four models of fish breeding have their own advantages and disadvantages. Choosing the right model requires considering multiple factors such as breeding species, economic costs, and environmental factors.

3. Which fish species are suitable for breeding under the pig model?

It is feasible for some omnivorous crucian carp, carp, etc., and increasing the plankton content by fertilizing the water with manure can help the growth of silver carp and bighead carp. Basically, it can be used, but it should not be used for fish with higher water quality requirements, such as rainbow trout and mandarin fish.

It is best to use it to fertilize the water after cleaning the pond. During the breeding period, try to control it to avoid deteriorating the water quality.
