Problems solved by technology

[0004] In order to solve the problems that the existing breeding methods of white prawns cannot determine the kinship and can not separate the larvae with high vigor from the larvae with poor vigor and dead larvae, a method for artificial indoor hatching and larvae selection of white prawn is proposed. Adopt the following technical solutions to achieve:

Embodiment Construction

[0026] The methods for artificial indoor hatching and juvenile selection of white prawns in this example include equipment preparation, water body preparation, selection of broodstock for broodstock, cultivation of broodstock during hatching period, and selection of juveniles.

[0027] refer to figure 1 and figure 2 , the equipment includes an incubator 1 , an inflatable tube 3 , a base 4 , a spotlight 5 , a siphon 6 and a collection net 8 . The hatching bucket 1 is made of translucent PVC material, with a mouth diameter of 38cm, a bottom diameter of 36cm, and a bucket height of 45cm; the bucket is covered with a lid 2, which is also made of a translucent PVC material with a diameter of 40cm; The inflatable tube 3 is connected with the microporous air stone 9; the base 4 is black, with a diameter of 37 cm, and a support frame with a height of 30 cm is provided under the base; the spotlight is a 3-5 watt energy-saving lamp, which is installed on the base 4 ; The inner diamet...

Abstract

The invention provides a method for manually hatching palaemon carinicauda indoors and preferentially selecting larvas. The method includes: A, preparing a hatching barrel; B, preparing water; C, selecting ovigerous parent shrimps; D, culturing parent shrimps during hatching period; and E, preferentially selecting the larvas. Every ovigerous shrimp is cultured separately indoors, so that after the lavas is hatched, genetic relationship is clear, and the method can be used for establishing families and selecting breeding. In addition, development rate and hatching time of a fertilized ovum can be adjusted by appropriately adjusting water temperature. The hatching barrel is white and semitransparent, the barrel bottom contacts with a black base and is light-proof, so that larvas with strong vigour can be collected at spotlight positions on the barrel wall.

Description

technical field [0001] The invention belongs to shrimp breeding technology, and in particular relates to a method for artificial indoor hatching and larvae selection of real shrimps. Background technique [0002] Exopalaemon carinicauda belongs to true shrimps. Its reproductive method is essentially different from that of prawns. It belongs to ovipositor reproduction. After mating, the fertilized eggs are held on the abdominal limbs for development, and the continuous swinging of the abdominal limbs is used to provide enough for embryonic development. Oxygen, the larvae leave the mother after hatching, and the hatched larvae are daphnia. Compared with the embryonic development time of prawns, the embryonic development time of prawns is much longer than that of prawns. At the same time, the amount of eggs held by the white prawn is generally only a few hundred to a few thousand, which is far less than that of the prawn. Therefore, some hatching methods and equipment of fert...
