1. Is sea bass a freshwater fish or a marine fish? Can it be raised in seawater?

There are many varieties of perch, some of which live in freshwater and are considered freshwater fish. For example, Australian gem perch, spotted perch and other perch are typical freshwater perch. There are also some varieties of perch that live in the ocean, such as silver perch, pale long perch, red perch, big-eyed blue perch, etc. Because they live in the ocean, they are not freshwater fish, but marine fish. 1. Is perch a freshwater fish or a marine fish? Perch is a relatively common fish and has edible value. Perch has many different varieties, and the differences between these different varieties are relatively large. For example, their living environments are different. Some perch varieties live in the ocean and are considered marine fish; some live in freshwater and are freshwater fish.

Sea bass living in the ocean are mostly distributed in the shallow seas of Japan, and are also distributed in the shallow seas near the coast of my country. During the fishing season every year, these sea bass will swim to freshwater areas, such as rivers and lakes, so they can also live in freshwater. If you want to eat them, it is best to choose sea bass that originally lived in the ocean, because they taste better, have more delicious meat, and contain higher nutritional value.

2. Can sea bass be raised in seawater? As mentioned above, there are many different species of sea bass, and their living environments are different. Some sea bass live in shallow sea areas and have adapted to the marine environment, so they can be raised in seawater. However, some species live in freshwater and have adapted to the freshwater environment. If they are raised in seawater, they will not be able to adapt, and may even die because they cannot adapt for a while. Therefore, whether sea bass can be raised in seawater depends on the specific species, and the appropriate water quality should be selected according to the specific requirements of the species.

1. What are the common diseases of Atlas fish?

Answer: Atlas fish have strong disease resistance and rarely get sick, but we must also adhere to the principle of prevention first, and pay attention to the cleaning and disinfection of the aquarium. Common diseases include fin rot (mainly occurring at the end of the pectoral fin) and bubble disease (mainly occurring in the pectoral fins, pelvic fins, abdomen and other parts). Fin rot disease prevention and control methods: ① Use high-efficiency disinfectant to spray 0.3×10-6 —0.5×10-6 liquid into the tank. ② Use 10-5—3×10-5 PVP-I for about 10 minutes. Bubble disease prevention and control methods: ① Aeration. The water temperature should be controlled to be stable so that the supersaturated oxygen in the water can be released into the air. ② Completely change the water and drain the old water.

2. What should we pay attention to in daily life?

Answer: The Atlas fish is easy to raise and reproduce, so it is popular among people. It is not demanding on the water for feeding. It can live normally in weakly acidic, neutral and alkaline water. The suitable water temperature is 22-26 degrees Celsius. The Atlas fish looks clumsy, but it is actually very flexible in swimming, agile in hunting, and relatively greedy. It likes to eat animal live bait. It is a carnivorous and ferocious fish. It can eat earthworms, tadpoles, small fish and shrimps, so it is not suitable to be raised with other fish. When feeding it at home, pay attention to its omnivorous nature. In addition to feeding it some small fish, shrimps and tadpoles, you can also feed it some lean meat, etc., so as to avoid making it monotonous in diet and not eating anything other than fish and shrimp.

3. How to reproduce?

Answer: The map fish is an oviparous fish that reaches maturity at 18 months of age. It can reproduce several times a year, mostly in summer and autumn, so reproduction is not difficult.

Generally speaking, if you keep multiple map fish in a breeding tank, when they reach sexual maturity, they will fall in love and find a mate. Just put the naturally paired parent fish into the breeding box. The breeding box should also be larger, and the water hardness should be 7-10, pH 7-8, and the water temperature should be 25-26 degrees Celsius. Put some smooth stones or porcelain plates in the breeding box as egg-laying attachments. Before laying eggs, the parent fish should first clean the attachments with their mouths, and then lay eggs on them.

Generally, each female fish can produce about 800 eggs, and some can produce more than 2,000 eggs. The map fish has the habit of protecting its eggs. The fertilized eggs can hatch into fry in about 48 hours. At this time, the parent fish should be removed and raised separately to avoid swallowing and harming the fry. After about 5 days, the fry will start to swim and look for food. The first food should be fed with "returning water", and then small fish worms can be fed after 1 week.

Because the Atlas fish is large, you must choose a larger aquarium when raising it. You can plant some water plants and change 1/5 of the water for each person. The color of the Atlas fish varies with age and size, and the brightness is closely related to light. When raising it, you should give it sufficient light. The Atlas fish is a stratum water fish. It grows quickly and has a long lifespan. It can live for more than 10 years. It can be said to be a long-lived tropical fish.

4. What other fish can be raised together with the map fish?

A: It can be raised with blood parrot fish, seven-star knife fish, ruby ​​fish (starlight perch), silver shark and other fish, but not with small fish such as red lantern and cardinal lantern. The principle of matching is to give priority to map fish, and other matching fish should be in even numbers or in pairs of male and female. The density depends on the size of the fish, and the total number of fish should be controlled at 6-12.

3. Tropical fish map feeding

Map fish are easy to raise and are hardy. They can eat and poop. The more you put in, the more it eats. After eating, it will lie at the bottom of the tank with its body tilted.
