1. Water quality conditions
Before choosing fish suitable for raising in outdoor pools, you need to understand the water quality of your pool. Different species of fish require different water temperatures, pH levels and water hardness. For example, in areas with lower water temperatures, it is often recommended to breed rainbow trout and trout, while in areas with higher water temperatures, crucian carp and grass carp may be more suitable. In addition, grass carp does not have high requirements for water quality and is suitable for beginners, while crucian carp requires higher water quality standards.
In addition, the size and number of fish will also have an impact on water quality. Over-feeding can lead to excessive bioburden, which exceeds the treatment capacity of the pool and reduces water quality. Therefore, be sure to feed according to the recommended feeding amount, change the water regularly, and use filters, oxygen pumps and other equipment to maintain stable water quality.
2. Fish species selection
Many different types of fish can be successfully cultured in outdoor pools. Common fish include grass carp, crucian carp, carp, trout, perch, red crucian carp and rainbow trout.
Grass carp and crucian carp are relatively cold-resistant, have good adaptability, and can tolerate some small-scale environmental fluctuations. The breeding of red crucian carp and rainbow trout requires an environment with relatively stable temperature, but they grow rapidly, have strong appetites and have delicious flavor, so they are widely selected as breeding objects.
In addition, some rare ornamental fish, such as koi, goldfish and rainbow fish, can also be choices for raising fish in outdoor pools, but these fish will require more attention than ordinary fish. and maintenance.
3. Breeding skills
Correct breeding skills are the key to successful fish farming in outdoor pools. First, you need to maintain the right water temperature and adequate oxygen in your pool. Oxygen supply is particularly important during the summer, as the oxygen content in hot water drops, which can adversely affect fish.
Secondly, you need to feed at the right time. Overfeeding can cause residual food and fish waste to accumulate in the pool, reducing water quality. It is recommended to feed in batches, control the amount of food, clean fish feces and residual food regularly, and change the water regularly. At the same time, you need to pay attention to the movement and behavior of fish. If there are abnormalities, it may be a sign of fish disease, and timely measures need to be taken for treatment.
4. Outdoor pool planning
Before raising fish, you need to plan the outdoor pool and choose the appropriate location and size. The depth and area of ??the pool should be sufficient to meet the growth needs of the fish, and protective measures, such as nets or awnings, should also be considered to protect the fish from predators and bad weather.
Allow some space for aquatic plants, which can effectively help maintain water quality and provide shade and wind protection. Aquatic plants and algae also provide cover and feeding grounds for fish.
Raising fish in an outdoor pool requires patience and care, but with the right planning and farming techniques, you can successfully raise healthy and delicious fish. If you are a beginner, it is recommended to start by choosing fish that are adapted to environmental conditions and easy to care for. As you gain experience, you can gradually try more challenging species.
