What color are the fry of white goldfish and red goldfish?

Goldfish fry are born with green skin color, and they will change color when they grow to about 5cm.

Can the fish fry bought in Guangdong survive in Yunnan?

one,

It is a small freshwater fish that usually lives in slow-flowing or stagnant waters. It relies on freshwater mussels to reproduce. Its own range of activity is very small and its life span is not long, but its distribution range is very wide. This fish usually feeds on algae, and also eats zooplankton and aquatic insects.

2. IOU

The white striped fish, also known as the blue knife, is distributed in major water systems in my country. It has a long body, a pointed head, and moves very quickly. It prefers to live in the upper layer of the water body and is relatively active. It usually lays eggs in May and June. It grows slowly, but there are many of them, so it has certain economic value.

3. Goby

Goby is a general term for fish of the family Goby. They are short, only a few centimeters long, but there are many species. They are mainly found in tropical and subtropical waters, and can also adapt to fresh water. This fish has poor swimming ability and a narrow range of activities. A few of them have the characteristics of migration, and usually feed on smaller fish and shrimp.

4. Yellow catfish

Yellow catfish is a common freshwater fish with a large mouth and a small dorsal fin. It lives in areas with slow currents and abundant aquatic plants. As an omnivorous fish, it generally lives at the bottom of the water and feeds on insects, snails, clams, fish and shrimps, and also eats plant debris.

3. What kind of ornamental fish is suitable for raising in Yunnan?

Lotus fish refers specifically to a special species of fish obtained from some fish (mutations), that is, the whole body is lotus pink and white, the gill cover is slightly red or dark red, like transparent. This mutation mostly appears in crucian carp and carp (some are scaleless).

Because it is a mutant, it is relatively rare, and its color is light and beautiful, so some people regard it as an ornamental fish. However, it has not been widely popularized, and the specific breeding method is the same as that of goldfish.

4. What kind of aquatic products are suitable for raising in Yunnan?

1. "Tilapia" is a tropical fish native to Africa. It is tender and juicy, delicious, without small bones, and easy to eat. Tilapia (Tilapia), commonly known as African crucian carp, belongs to the order Perciformes, the suborder Perciformes, the family Cichlidae, and the genus Tilapia (also known as the family Cichlidae). This genus is native to Africa and has more than 600 species, of which 15 are currently farmed. Tilapia is a group of small and medium-sized fish. Its appearance and individual size are somewhat similar to crucian carp, and its fins are more like those of mandarin fish. It is a euryhaline fish that can survive in both sea and fresh water; it tolerates low oxygen and generally lives in the lower layer of water, but changes the water layer with changes in water temperature or fish size.

Tilapia has a wide range of diets, most of which are omnivorous and mainly plant-based. They are very greedy and have a large food intake. They grow rapidly, especially in the juvenile stage. Tilapia growth is closely related to temperature, with a growth temperature of 16 to 38 degrees Celsius and an optimum temperature of 22 to 35 degrees Celsius.

Tilapia was first introduced to Taiwan Province from Singapore by Wu Zhenhui and Guo Qichang in 1946. In memory of these two people, it was first called "Tilapia". It was introduced to mainland my country from Vietnam in 1957 and is also known as "Vietnamese fish". Because it is native to Africa and looks like local crucian carp, some people call it "African crucian carp".

There are two kinds of tilapia introduced to Yingshan Hot Spring in Hubei: one is called Mozambique tilapia, which was brought to Yingshan Hot Spring from Jingshan County in 1972; the other is called Nile tilapia, which was introduced by Hubei Fisheries Research Institute in 1979. After they settled down, they all lived well.

Dr. Modadugu Vijay Gupta of India won the 2005 World Food Prize for developing and disseminating low-cost technology for freshwater aquaculture (using tilapia).

However, due to its stringent breeding requirements, tilapia is only farmed in a few tropical cities in my country and cities with constant temperature throughout the year like Kunming. Therefore, if you go to Kunming, it would be a great pity not to eat tilapia.

2. Maoming, Guangdong Province has a tropical monsoon warm and humid climate, with sufficient sunshine and rainfall. The average annual temperature in the city is about 23℃. Tilapia farming was introduced in the 1950s. After nearly ten years of development, the city's tilapia farming area has reached 220,000 mu, accounting for about 58% of the city's freshwater farming area. The annual output of tilapia is 180,000 tons, accounting for 1/3 of the province's output and 1/6 of the country's output. The annual output value exceeds 1.5 billion yuan, making it the largest tilapia production area in China. In January this year, Maoming City was awarded the title of "China's Tilapia Capital" by the China Aquatic Products Circulation and Processing Association.

5. What freshwater fish are suitable for breeding in Yunnan?

Yunnan's plateau freshwater fish are not only delicious, bone-less, and nutritious, but also have some medicinal value. Among them, big-headed carp, Dianchi golden line, anti-wave fish, and bow fish are the most famous, known as the four famous indigenous fish.

Anti-wave fish

It is produced in Fuxian Lake in Yuxi. The fish has a silvery white body, slender and slightly flattened, like a narrow spindle; the back is straight, the belly edge is shallowly arc-shaped, and the head is significantly longer than the body height.

There is a row of large scales on each side of the anus and anal fins, and a crack forms on the abdomen between the large scales on both sides. It is named because it can hold its tail with its mouth when jumping, which looks like a bent bow.

9. Freshwater fish species suitable for breeding in Yunnan

Yunnan is suitable for breeding tilapia

The temperature in Yunnan is relatively high all year round, especially in places like Pu'er and Jinghong, where the average temperature is above 20 degrees all year round. This climate is very suitable for tilapia farming.

Tilapia farming is very simple. It eats almost everything, especially feces. Due to the low technical difficulty in farming, the suitable temperature and the large-scale reproduction, more people eat it.

10. Rare freshwater fish that can be farmed

That's basically the golden arowana and the silver arowana
