It takes about 1 year if it is raised in a greenhouse, and about 3 years if it is raised in the wild.

The most important reason for the slow growth of snapper is that it has a long hibernation period. Under natural conditions, snapper hibernate from October to April every year, during which time snapper do not eat and do not move, not only to stop growing, but also to lose weight because of their own consumption.

Introduction

The reality is that farmers generally through the means of temperature control to shorten the breeding cycle, improve the growth rate of young snappers suitable for the growth of the temperature in the 25-30 degrees Celsius, the general situation of the natural conditions of the water temperature in the range of up to two months, so farmers like to utilize the hot springs water, the factory's residual hot water or other temperature control measures to make water, the water temperature in the range of 25-30 degrees Celsius, the natural conditions of the water temperature at most two months. Therefore, farmers like to use hot spring water, factory waste water or other temperature control measures to keep the water temperature at about 30 degrees Celsius all year round.

In this way, the snappers are in the best growing environment, feeding vigorously, and maintain rapid growth throughout the year, which greatly shortens the production cycle and realizes rapid breeding, and generally the snapper fry can reach the commercial specifications in only 10-12 months.
