How to adjust seafood water? How to adjust seawater for raising marine fish

The suitable water temperature for seafood is generally maintained at 18 -21, but abalone and geoduck are low-temperature and high-salt varieties, and their adaptation temperature is 12 -15. When the temperature is too high, it is not good for the stored organisms, and it is easy to cause diseases and losses.

Tips for using pump aeration in aquaculture:

In addition to stocking the water before aquaculture, and the need to use water pumps when drying ponds, the water pumps also play the role of increasing oxygen or regulating water quality in the breeding process, but if the water pump is used improperly, it will not only cause energy waste, but also can not play the role of the pump. The scientific and reasonable use of the pump is introduced as follows:

1. Adjust the water inlet of the water pump to ensure the inhalation of the upper layer of water rich in dissolved oxygen. The inlet of the pump should generally be within 1 meter of the water source under the water, the inlet extends into the water layer too deep, then the inhaled water dissolved oxygen is less, and the aeration effect is poor, if the bottom water is inhaled when the floating head is rescued, because the bottom water temperature is low, it is easy to form a density flow after entering the pond, but the floating head becomes serious.

2. Daily oxygenation, water pump water into the pond at noon on sunny days. The pump can be flushed high to flush the water into the bottom layer as much as possible to reduce the "oxygen debt" of the bottom layer. In the evening, it should not be oxygenated with injected bottom water.

3. Add a water fall board at the falling water. On the one hand, it reduces the erosion damage of the pond slope by the water flow, and on the other hand, it expands the contact surface between water and air and increases the oxygen entering the pond.

4. When rescuing the floating head, the nozzle of the pump should be level with the water surface. It can also reduce the impact of water flow on fish, avoid excessive oxygen consumption by fish during strenuous exercise, and prevent the mixing and circulation of water, and the consumption of dissolved oxygen from the bottom water to the surface. When using a pump to save fish, you must wait until there are no fish in the water before stopping the machine, and remember to shut it down halfway.

Seawater for farmed marine fish can be used with tap water that has been exposed to the sun, or tap water can be used. Specialized sea salt is then added to the water to simulate seawater.

Normally, 1 liter of water with 30-35 grams of sea salt will do. After adding it, you need to stir it gently, and give it oxygen for 1-2 hours so that it can be used by the fish.

The blended seawater evaporates with the water, so keepers need to add sea salt regularly to keep the salt concentration stable.

There will be more equipment required to breed marine fish, such as fish tank lights, heating rods, protein skimmers, etc

1. Fish tank lights: Aquarium lights need to be installed for breeding marine fish, which not only have the role of lighting, but also increase the body color and ornamentality.

2. Insulation equipment: The requirements for water temperature of marine fish are high, and when artificial breeding, the power of the equipment needs to be selected according to the size of the fish tank.

3. Protein skimmer: Protein skimmer has a great effect on purifying water quality, they can concentrate the bubbles in the water and discharge them to achieve the effect of purifying water quality.
