CATDOLL : CATDOLL: How old is a rainbow snapper in one year?

1. How old does a rainbow snapper grow in one year?

The growth rate of rainbow snapper is more than 10% faster than that of ordinary tilapia. The individuals are also larger, have a low feed coefficient, and grow fat and attractive. Generally, adult fish can reach a weight of about 500g to 700g in one year of breeding, and the larger ones can reach more than 1000g.

About 500-600 grams per year

Rainbow snapper grows fast. When the fry are raised in the pond for 4 months, their average weight can reach 150 grams. If they are continued to be raised into the wintering period, some may reach 500 grams to 600 grams.

2. Is red snapper a marine fish or a freshwater fish? Can it be farmed?

Red snapper is a marine fish, not a freshwater fish. As a marine fish, red snapper is also relatively typical. They can adapt well to the seawater environment and have been living in the ocean. Specifically, red snapper is widely distributed in my country's waters and in large numbers. They have good adaptability, so they are found in the Bohai Sea, the Yellow Sea, the East China Sea and the South China Sea from the north to the south. In addition, red snapper itself is an edible fish, so it is not only a marine fish, but also seafood. 1. Is red snapper a marine fish or a freshwater fish? Red snapper is a widely distributed fish in my country and is relatively famous. Marine fish and freshwater fish are not a certain type of fish. They are two types of fish, and both types contain a lot of varieties. The living environment, living habits and appearance characteristics of these two types of fish are very different. Red snapper is one of the former, that is, marine fish. As a marine fish, red snapper is also relatively typical. They have been living in the ocean and can adapt well to the environment.

Specifically, red snapper is widely distributed in my country's waters, and its number is relatively large. They have a certain adaptability to water temperature, so they can be found in my country's waters with higher latitudes as well as in waters with lower latitudes. From north to south, red snapper is widely distributed in the Bohai Sea, the Yellow Sea, the East China Sea, and the South China Sea. In addition, red snapper itself is also an edible fish, so they are not just marine fish, but also seafood, that is, edible marine life.

2. Can red snapper be farmed? As mentioned above, red snapper is an edible marine fish and belongs to seafood. In fact, red snapper is not only edible, but also very suitable as a food ingredient. They taste very good and have delicious meat. They are popular with many people. There is also a certain demand for this fish in the market, so some people choose to farm this fish. However, red snapper is a fish that lives in seawater after all, and has certain requirements for the water environment. Therefore, it is different from farmed freshwater fish. It is more difficult to farm, so the farming range is not as wide as freshwater fish. Many of the red snappers seen on the market are directly caught, and farmed ones are in the minority.

3. Can ornamental snappers be kept together with parrot fish?

Yes, but the size should be similar. Relatively speaking, parrot fish are more ferocious, and the best parrot fish to keep are smaller.

Bream life habits:

Silver bream is a mid-upper layer fish, which adapts to the water temperature between 18-36℃, the best water temperature for growth is 24-32℃, and the lowest water temperature for survival is 12-15℃. When the water temperature drops to 15℃, the fish begin to stop eating and move less or not, and dive into the middle and lower layers of the water body. When the water temperature drops to 12℃, the fish begin to die. Silver bream can tolerate low oxygen and is not afraid of fertile water. The suitable pH value is 7-8. Silver bream likes to cluster and is omnivorous. It feeds on plankton in the fry stage, and feeds on various brans, bran cakes, grass and artificial compound feed in the fingerling and adult stages. The protein content of the feed is required to be 25%-33%. The fish matures early, and the breeding season is from April to October every year. It grows fast. Generally, the fry bred in the same year can grow to 0.5 kg after 4-5 months of breeding. The fish has strong disease resistance and no disease has been found. In addition, the fish is easy to catch, and the catch rate is over 90%.

Parrot fish growth habits:

The fish is oblong and very flattened. The head is short and high, with a sharp ridge on the dorsal margin. The mouth is large, forward, and can be extended. There is one row of jaw teeth, which are conical. There are often one to several rows of small teeth on the inner side. There is a pair of large canines on the front end, and no canines at the corners of the mouth. The preoperculum is smooth, the body is covered with medium-to-large round scales, the cheeks are generally scaleless or only have scales below the eyes, the lateral line is interrupted, and the lateral line scales are 18 to 22 + 4 to 9. Dorsal fins II, VII to 12 to 13, the 1st and 2nd fin spines are extended and filamentous, and are quite far away from the rear fin spines, connected by a very low fin membrane, anal fins III to 11 to 13, and the caudal fin is round. There are 4 horizontal bands on the sides of the body, and a black spot below the 6th to 7th dorsal fin spines.

Parrotfish use the plate-like teeth in their throats to grind up food and coral fragments. They can grow up to 1.2 metres (4 feet) in length and weigh up to 20 kilograms (45 pounds). The colour of the fish varies greatly between males and females of the same species, and between adults and juveniles. Parrotfish are edible, but the group as a whole is of little economic value. The banded parrotfish (Callyodon fasciatus) is the dominant parrotfish of the Indo-Pacific region, 46 centimetres (18 inches) long, with males being green and orange or green and red, while females are blue and yellow. The Atlantic species includes the queen parrotfish (Scarus vetula), which is about 50 centimetres (18 inches) long. The male is blue with green, red and orange hues, while the female is reddish or purple with a white stripe.

Parrot fish do not have the appearance of adult parrots when they are larvae. The appearance of the larvae will gradually change after three weeks: the head will be raised, the body will become round, and the body color will change from black to gray and then slowly to red. The life span can reach 4 to 5 years, but after three months, the physiological functions of parrot fish will show signs of aging, and they will lose their ornamental and commercial value.

4. How long does it take to grow a three-lake fish from 3cm to a full-year breeding?

Different species take different amounts of time to reach adulthood.

Tanzania cichlids refer to the cichlids of Lake Tanganyika in Africa. The environment of Lake Tanganyika includes habitats with large waves, shallow waters with steep rocks, deep water rock areas, deep water areas, open waters, sandy rock transition areas, shell environments, sandy areas, shallow waters rich in sediments, muddy bottom areas, etc. Different environments create different fish, and they also have different living habits and growth processes.

There are dozens of species of cichlids that have been used as ornamental fish, and their juvenile stages vary. For example, blue-eyed cichlids are mostly 3 cm long and are already adults, while Burundi six-striped cichlids are 35 cm long. It takes at least 2 years for a 3 cm cichlid to grow to adulthood.

5. Which is easier to keep, the Sanhu bream or the silver dragon? What fish can they be kept with?

Three Lake Cichlids, Tan Cichlids and Blue Six-striped Fish all belong to the Cichlid family. As long as they are not kept together with fish from other families and genera, fish of the same size, family and genus can be kept together. For example: African Cichlids, Flower Arowana, Spotted Tail Phoenix, Spotted Dwarf Cichlid, Emerald Phoenix, Banded Uri, White Jade Phoenix, T-shaped Dwarf Cichlid, Alianka Blue Sleeve Cichlid, White and Blue Dwarf Cichlid, Overlord Dwarf Cichlid, Angelfish, Egyptian Angelfish, Red Diamond, Akashi Dwarf Cichlid, Discus Angelfish, Blue Prince, Jack Angel, Golden Warship, Ruby, Blood Parrot, Continental Phoenix, Golden Pineapple, Sapphire, Map Fish, etc.

The following is an introduction to these three fish:

Three-lake cichlids. Belong to the class of bony fishes, the family of Cichlidae in the order of Perciformes, which is what we call the family of Cichlids. Among the fish species in the world, it can be said that the family of Cichlids is one of the most successful in evolution. It is found in all major waters around the world, with a total of about 200 genera and more than 2,000 species. It is the family with the largest number of species among bony fishes. Cichlids are native to tropical Central and South America, Africa and the West Indies. They have been introduced to all parts of the world because of their extremely high ornamental value. Today, they are the most common alien fish species in tropical and subtropical regions. Among them, the cichlids living in the three major lakes in central Africa (the three major lakes in Africa refer to Lake Tanganyika, Lake Malawi and Lake Victoria) have become the best choice for ornamental fish species because of their ever-changing colors, strong physique, elegant body shape and superb ability to adapt to water and soil.

The cichlid is a species of fish that is suitable for growing in an environment with abundant food and turbulent waters. The characteristics of these waters are that the lake water is often stirred, which keeps the water temperature quite constant, and also makes the dissolved oxygen rich. The pH value is higher than other areas. The shore even produces mineral crystals due to the impact of waves, forming a soft-edged rock plate habitat. The steep and narrow lakeshore is formed by huge pebbles. The shore is usually sandy or rocky, and the rocks are covered with algae, providing a good food source for algae-scraping organisms. There are unique cichlid biota here.

Blue six-striped fish. Native to Lake Tanganyika in Africa. Omnivorous, oviparous, suitable for rock landscaping, it is recommended to be kept alone
