Embodiment 1

[0017] 1. Set up hatching pools: Select 3 Limulus egg suspension hatching pools, with a length, width, and height of 5.0m*5.0m*1.2m, and set an overflow at a distance of 1.0m from the bottom of the pool to ensure that the water level in the hatching pool is 1.0m.

[0018] 2. Prepare the hatching basket: select a conical flat-bottomed plastic round basket with a diameter of 20 cm at the mouth of the basket and a diameter of 40 cm at the bottom of the basket. There are holes on the wall and bottom of the basket. 14 mesh. A foam float is arranged on the upper edge of the basket to keep the upper mouth of the basket above the water surface by 2.5cm. Soak in 50ppm potassium permanganate solution for 30 minutes for disinfection. After disinfection, the prepared hatching baskets are put into the hatching pool on the day when the horseshoe crab eggs are put into the pool for standby use. An air blowing and oxygenating head is placed in each basket to keep the water in the basket boili...

Embodiment 2

[0023] 1. Set up hatching pools: Select five suspension hatching pools for horseshoe crab eggs, with a length, width, and height of 3.0m*3.0m*1.0m, and set an overflow at 0.8m from the bottom of the pool to ensure that the water level in the hatching pool is 0.8m.

[0024] 2. Prepare the hatching basket: choose a conical flat-bottomed plastic round basket with a diameter of 15cm at the mouth of the basket and a diameter of 20cm at the bottom of the basket. There are holes in the wall and bottom of the basket. 12 mesh. A foam float is arranged on the upper edge of the basket to keep the upper mouth of the basket above the water surface by 3 cm. Soak in 50ppm potassium permanganate solution for 30 minutes for disinfection. After disinfection, the prepared hatching baskets are put into the hatching pool on the day when the horseshoe crab eggs are put into the pool for standby use. An air blowing and oxygenating head is placed in each basket to keep the water in the basket boiling...

Embodiment 3

[0029] 1. Set up the hatching pool: Select 6 horseshoe crab egg suspension hatching pools, the size is 3.8m*5m*1.5m, and the overflow port is set at 1.3m from the bottom of the pool to ensure that the water level in the hatching pool is 1.3m.

[0030] 2. Prepare the hatching basket: choose a conical flat-bottomed plastic round basket with a diameter of 45 cm at the mouth of the basket and a diameter of 50 cm at the bottom of the basket. There are holes on the wall and bottom of the basket. 20 mesh. A foam float is arranged on the upper edge of the basket to keep the upper mouth of the basket above the water surface by 3 cm. Soak in 50ppm potassium permanganate solution for 30 minutes for disinfection. After disinfection, the prepared hatching baskets are put into the hatching pool on the day when the horseshoe crab eggs are put into the pool for standby use. An air blowing and oxygenating head is placed in each basket to keep the water in the basket boiling.

Abstract

The invention discloses a suspended artificial incubation method for Tachypleus tridentatus. The suspended artificial incubation method mainly comprises the following steps: firstly, arranging an incubation pond; secondly, preparing for an incubation basket; thirdly, selecting and disinfecting Tachypleus tridentatus eggs; fourthly, placing the Tachypleus tridentatus eggs into the incubation basket; and fifthly, carrying out daily management. The incubation basket is a conical plastic basket which is narrow at the upper part and wide at the lower part, and holes are formed in the walls and thebottom of the incubation basket. An opening of the incubation basket is provided with foam made of a light material. The Tachypleus tridentatus eggs are incubated in the incubation basket suspended inwater, the environment where the Tachypleus tridentatus eggs are located contains a great deal of oxygen and water, and compared with an incubation method by which the Tachypleus tridentatus eggs areplaced in sand, the suspended artificial incubation method omits processes of disinfecting and cleaning the sand and the water and avoids transfer operation in an incubation process. The incubation basket adopted in the suspended artificial incubation method is narrow at the upper part and wide at the lower part, the opening is relatively small, a basket body is conical, and due to the adoption of the inclined walls of the incubation basket, the phenomenon that the Tachypleus tridentatus eggs are taken out of the incubation basket by a great deal of water is restricted. By using the improvedincubation method, the incubation rate can be increased, the incubation time can be shortened, and the Tachypleus tridentatus eggs can be prevented from falling out of an incubation vessel.

Description

technical field [0001] The invention relates to the artificial breeding technology of Chinese horseshoe crab, in particular to a suspension artificial hatching method of Chinese horseshoe crab. Background technique [0002] Horseshoe crabs are present at the end of the Paleozoic Devonian period 400 million years ago, and are the only ancient species left on the earth. Chinese horseshoe crab (Tachypleus tridentatus) belongs to the rare species of Limulus, also known as Oriental horseshoe crab, three-spined horseshoe crab, horseshoe crab, and Chinese horseshoe crab. Chinese horseshoe crab is green-brown or dark brown in appearance, covered with a hard carapace, and its body consists of three parts: cephalothorax, abdomen and sword tail. Chinese horseshoe crab has high research value in biological evolution, marine bionics, medicine, food, etc. The amoeba cell extract in Limulus blood is commonly known as Limulus reagent, using the amebocyte lysate (LAL) in the blue blood of ...
