Industrial seed culture production line for Tilapia mossambica

Abstract

In order to solve the problem that fry culture occupies a hatching device for a long time in the prior Tilapia mossambica industrial hatching, the invention establishes an indoor industrial seed culture production line with controllable conditions, so that the hatched fries can be transferred on a culture production line in a fry culture workshop along with a fry collecting box. The industrial seed culture production line for the Tilapia mossambica is characterized in that the production line formed by connecting a water pump, a water inlet pipe, a water spray pipe, the fry collecting box, a water collecting tank, a backflow pipe, a water storage pond and a temperature and oxygen increasing device. The fry culture on the product line can improve the hatching efficiency, save labor and physical resources, carry out fry culture of large scale and multi batches and has convenient operation and controllable conditions.

Description

technical field [0001] The invention belongs to tilapia industrial seedling raising production equipment, in particular to seedling raising facilities capable of large batches, multi-batches, multi-categories, and indoor controllable conditions. Background technique [0002] Currently, tilapia fry are reared only in cages or ponds. However, in the hatching workshop for tilapia factory hatching, since it takes two to three days for the fry to open after hatching, they cannot be placed in net cages or ponds for cultivation during this period, and must be kept in the seedling box. Occupying the hatching equipment like this greatly reduces the production efficiency of the hatching workshop, especially in the case of large-scale, multi-batch breeding and the contradiction with the shortage of hatching equipment is particularly prominent. On the other hand, due to the large difference in the emergence time of fish eggs in each hatching tank, if the fry in each seedling box are mi...

AI Technical Summary

Problems solved by technology

However, during the industrialized hatching of tilapia in the hatching workshop, since it takes two to three days for the fry to open after hatching, they cannot be placed in net cages or ponds for cultivation during this period, and must be kept in the seedling box. Occupying the hatching equipment like this greatly reduces the production efficiency of the hatching workshop, especially in the case of large-scale, multi-batch breeding and the contradiction with the shortage of hatching equipment is particularly prominent

On the other hand, due to the large difference in the emergence time of fish eggs in each hatching tank, if the fry in each seedling box are mixed together, the size of the fry will be uneven, resulting in uneven size of adult fish Irregularity affects the quality of commercial fish; if cages are used for separate breeding, many cages will be used, occupying a large amount of water, consuming manpower and material resources, and the conditions for fry breeding are not easy to control, resulting in low quality fish fry
