1. California bass is a carnivorous fish. Will large differences in the size of the fry affect later breeding?

California bass is a carnivorous fish. During the breeding process, the specifications of the same batch of fry should be kept neat, otherwise they are easy to eat each other. In addition, if the specifications of the fry are too different, it will affect the later reproduction and even fail to reproduce. Therefore, understanding and being familiar with the specifications of the fry is the basis of fish farming. Here are some specifications of California bass fry. Fish flower Fish flower, also known as "water flower", refers to the fry hatched from fish eggs, with a length of 7-8 mm. In some areas, it directly refers to the length of the fry from hatching to 1 inch (3.33 cm). It is commonly known as "egg yolk fry" in South China and Southwest China, and "hairy fry" in East China. Young and old fry are divided into tender fry and old fry. Tender fry are transparent, less pigmented, the swim bladder (waist point) does not appear, and the tail fin and dorsal fin are not separated; old fry are rich in pigment and swim horizontally in the water.

After 10-15 days of feeding, black sesame develops into 1.5-2.0 cm long fry, which are called "black eggs" and "black sesame". After 10-15 days of feeding, summer flowers (centimeter seedlings) develop into 3-5 cm long fry, which are called "summer flowers" because they are in summer. In some places, fry with a body length of about 3 cm after 20-30 days of feeding are directly called "summer flowers", while in some areas of Guangdong, they are also called "fire slices" and "inch slices". Selecting seedlings before stocking is a link that farmers need to pay great attention to. The quality of fry is related to its survival rate, growth rate and disease resistance. High-quality fry have a high survival rate, fast growth rate and strong disease resistance, while the opposite is true for low-quality fry.

Farmers may be worried when buying fish fry. What is a good fry? Most of the fish fry sold on the market are artificially bred. Due to the influence of egg quality and hatching environment, the physique of the fry is different, which directly affects the survival and growth in the later stage. Mastering the level of fry is one of the key steps in good fish farming. Detailed specifications of California bass fry, how to judge whether the California bass fry is excellent? Observe the appearance: high-quality California bass fry, neat specifications, uniform body color, clean and shiny fish body, slightly yellow or slightly red, strong body, smooth and not muddy; inferior fry, different specifications, different group pigments, are "color fry", thin body, silt.

High-quality California bass fry are active, swim in groups, dive into the water quickly after being startled, do not often stay on the water surface, and have strong ability to snatch food; poor-quality fry move slowly, do not cluster, roam on the water surface, and have weak ability to snatch food. Blowing mouth observation: Put the California bass in a basin and blow the water surface appropriately with your mouth. High-quality fry can swim upstream; low-quality fry go with the flow and cannot withstand the water. Pouring water observation: For high-quality California bass fry, scoop the fry into the basin and slowly pour water. High-quality fry struggle violently underwater, with their heads and tails bent into a circle; low-quality fry drill into the bottom of the basin, unable to struggle, and only their heads and tails can twist slightly. Vortex observation: For high-quality California bass fry, stir the container with your hands or a wooden stick to create a vortex in the water. High-quality fry can swim upstream along the edge; low-quality fry are trapped in the vortex and cannot swim backwards.

I think so. If the size of the fry is too different, it may lead to different development of the fish and different feeding.

Of course it will have an impact. If the size is too large, it will make later breeding very difficult and will also affect the output after breeding.

California bass is a carnivorous fish. During the breeding process, the size of the fry in the same batch needs to be kept uniform, otherwise the fry will easily cannibalize each other. In addition, if the size of the fry is too different, it will affect the later breeding and even fail.

Yes. Because if the difference is too big, it will lead to great differences in later breeding and production, and will also affect your own economic benefits and harvest.

2. What should you pay attention to when buying sea bass fry online?

The details are as follows:

1. The temperature for the seedlings should be between 20-25 degrees. Too low a temperature will slow down the growth of the sea bass seedlings.

2. As sea bass is a carnivorous fish, the sizes of seedlings in the same batch must be kept uniform, otherwise they will cannibalize each other.

3. Water quality indicators must be met, such as dissolved oxygen must be ≥5ppm.

3. What does the perch splash mean?

California sea bass fry.

It refers to a type of bass, the newly hatched California bass, commonly known as splash bass.

Ordinary farmers buy water fry and put them in the pond to cultivate standard fry, starting the second stage of breeding. There are two ways to safely transport water fry. One is to use large barrels, which is suitable for short-distance transportation, can transport a large number of water fry, and is easy to load and unload. The large barrels must be equipped with an oxygenation system to add oxygen to the bottom of the seedling barrel.
