Restoration culture method for injured Chinese horseshoe crab

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.

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...

Problems solved by technology

Due to the custom of eating Chinese horseshoe crab along the coast of the Beibu Gulf and the endless fishing of Chinese horseshoe crabs by illegal traders for economic benefits, several southern coastal provinces have listed Chinese horseshoe crabs as a second-class protected animal. In 2019, Chinese horseshoe crabs have entered the international endangered species red Therefore, the protection work of Chinese horseshoe crabs is actively carried out, and in the work of protecting and rescuing Chinese horseshoe crabs, the problem of artificial recovery and cultivation of injured Chinese horseshoe crabs is particularly prominent
