Embodiment 1

[0011] (1) Repair pool treatment: Clean the inner wall and bottom of the pool with a mixture of 30mL of detergent containing garlic and 30L of fresh water, and then evenly spray 28L of 5ppm oxalic acid solution for disinfection. The next day, rinse the restoration pool with fresh water until there is no oxalic acid, lay a 20-25cm sandy bottom, add 10ppm potassium permanganate to 45cm to soak and disinfect for 30min, and then rinse the sandy bottom with fresh water until there is no potassium permanganate left. The restoration pool was dried in the sun for a day and a night, and 50cm of fresh seawater was added after sand filtration, dark treatment in a black room, and disinfection by ultraviolet light. The temperature of the seawater is 28°C, the specific gravity is 1.020, and the pH is 7.8. Air pipes are evenly arranged in the pool to continuously inflate the water to keep the dissolved oxygen above 5mg / L.

[0016] (1) Repair pool treatment: Clean the inner wall and bottom of the pool with a mixture of 30 mL of detergent containing garlic and 30 L of fresh water, and then evenly spray 25 L of 5 ppm oxalic acid solution for disinfection. The next day, rinse the restoration pool with fresh water until there is no oxalic acid, lay a 20-25cm sandy bottom, add 10ppm potassium permanganate to 40cm to soak and disinfect for 30min, and then rinse the sandy bottom with fresh water until there is no potassium permanganate left. The restoration pool was dried in the sun for a day and a night, and 58cm of fresh seawater was added after sand filtration, dark treatment in a black room, and disinfection by ultraviolet light. The temperature of the seawater is 30°C, the specific gravity is 1.021, and the pH is 8.0. Air pipes are evenly arranged in the pool for continuous inflation to keep the dissolved oxygen above 5mg / L.

[0021] (1) Repair pool treatment: Clean the inner wall and bottom of the pool with a mixture of 30 mL of detergent containing garlic and 30 L of fresh water, and then evenly spray 30 L of 5 ppm oxalic acid solution for disinfection. The next day, rinse the restoration pool with fresh water until there is no oxalic acid, lay a 25-30cm sandy bottom, add 10ppm potassium permanganate to 50cm to soak and disinfect for 30min, and then rinse the sandy bottom with fresh water until there is no potassium permanganate left. The restoration pool was dried in the sun for a day and a night, and 60cm of fresh seawater was added after sand filtration, dark treatment in a black room, and disinfection by ultraviolet light. The temperature of the seawater is 29.8°C, the specific gravity is 1.022, and the pH is 8.2. Air pipes are evenly arranged in the pool for continuous inflation to keep the dissolved oxygen above 5mg / L. ;

Abstract

The invention discloses a restoration culture method for an injured Chinese horseshoe crab. The method comprises the following steps: cleaning the internal wall and bottom of a pool with an garlic detergent, sprinkling an oxalic acid solution for disinfection, and flushing the repair pool with fresh water on next day until no oxalic acid solution remains; laying a sandy bottom of 20cm-30cm, carrying out soaking disinfection for 30min with 10ppm potassium permanganate, and flushing the sandy bottom with fresh water until no potassium permanganate remains; subjecting the repair pool to sun curing for 24 hours, and adding fresh seawater subjected to sand filtration, dark and ultraviolet light disinfecting treatment; uniformly laying gas pipes to continuously inflate, so as to keep dissolved oxygen to be 5mg/L or more; rinsing out the injured Chinese horseshoe crab with the seawater in the repair pool, and carrying out disinfecting for 15min; placing the treated injured Chinese horseshoe crab into the repair pool, and carrying out culture with running water; lowering the water level to 15cm to 20cm every morning; feeding fresh waste fish or oyster meat in the afternoon of first severaldays, and cleaning remaining remnant bait after the injured Chinese horseshoe crab finishes food intake; adjusting a feeding amount at a later stage according to food intake conditions; and carryingout culture until rapid body contraction reduction is achieved through touch in water and the food intake conditions are stable.

Description

technical field [0001] The invention relates to a recovery breeding method for injured Chinese horseshoe crab, which belongs to the technical field of aquaculture. Background technique [0002] Chinese horseshoe crab (Tachypleus tridentatus) belongs to the rare species of Limulus. Chinese horseshoe crab is blue-brown or dark brown in appearance, covered with hard carapace. The body consists of three parts: head, chest, abdomen and sword tail. Horseshoe crab appeared at the end of the Paleozoic Devonian period 400 million years ago, and is one of the few remaining ancient species on the earth. Although it has gone through a long period of time, the horseshoe crab still retains its original characteristics and is known as the "living fossil" in the sea. Because most of the activities of horseshoe crabs are male and female in pairs, they have the reputation of "undersea mandarin ducks". And the Chinese horseshoe crab has high research value in biological evolution, marine b...
