How long are 8-day-old tilapia fry?

Depending on the fatness, the 8-day-old tilapia is generally between 2.5cm and 4cm, and most are 3cm. The incubation takes about a week, and the growth speed from hatching to 8 days depends on the water temperature. When the water temperature is 30 degrees Celsius, it generally takes 25 to 35 days depending on the water quality. Low-density large water body. Under the premise of not damaging the water quality, whether the fish eats or not, the daily feeding amount should be more than 10% of the body weight. When the water quality is rich, you can not feed. For small water bodies, feed according to the appetite of the fish, and do not feed too much.

How much is the largest fish in the world?

The largest fish in the world - whale shark

There are many kinds of sharks, the largest of which is the whale shark. The whale shark can reach a length of 20 meters and a weight of 20 tons, making it the largest existing fish in the world. Its body is gray-brown or blue-brown with many yellow spots or stripes. Its mouth is very wide, almost as wide as its head, but its teeth are very small, with hundreds of teeth on each of its upper and lower jaws. Its gill arches have keratinous gill rakers, which are divided into many small branches and cross-linked to form a sponge-like "filter". When it opens its mouth wide, seawater and small organisms rush into its mouth, and then it closes its mouth, and the water is discharged from the gaps in the gill rakers, while the small organisms remain in its mouth and become its food. Its food includes plankton and small fish. Thank you for accepting my answer.
