Technical Field
The invention relates to the technical field of marine organism breeding, in particular to a tachypleus amebocyte lysate rapid fattening breeding method for blood extraction.
Background
The horseshoe crab is an ancient marine organism, has been developed for 4.5 hundred million years, is called as 'biological activated stone' and is an indispensable important member of coastal wetlands and marine ecosystems. The tachypleus sinensis belongs to the order Campholes of the phylum Arthropoda, and lives on the sandy seabed of the shallow sea, and is a carnivorous animal, a feeding link animal, a mollusk and the like, and sometimes also feeds on the submarine algae. The growth cycle of the Tachypleus tridentatus is long, and the Tachypleus tridentatus can be propagated in nearly 13 years, and the northern gulf of Guangxi is one of the most important habitats of the Tachypleus tridentatus.
In the last 50 s, the blood of horseshoe crabs can be prepared into an important bacterium detection reagent, namely horseshoe crab reagent, so that the bacterium can be detected most quickly and accurately. The use of limulus reagents has been infiltrated into various fields of detection biology, medical research, food processing, and the like. Fan Lin and the like find that the limulus reagent dynamic turbidity method can accurately detect the recombinant human coagulation factor VIII bacterial endotoxin. Solano et al found that limulus reagents can be used to detect endotoxin content of antivenin.
The number of limulus populations continues to decline due to the tremendous demand for limulus reagents from the market. According to investigation, in nearly 30 years, the number of tachypleus tridentatus populations in the northern gulf of Guangxi has been reduced by more than 90%, and at present, the number of tachypleus tridentatus is still sharply reduced every year, and the shoot at a risk.

step four, 6-15 years of horseshoe crab fish: in the 6-year and 15-year horseshoe crab culturing process, keeping the temperature of culturing seawater every day at 28-32 ℃, conveying oxygen into the culturing units through an oxygen increasing machine every 3-5 hours, placing oysters and conchs into a crushing device, crushing the oysters and the conchs into blocks, pouring 5-8 kg of food into each culturing unit every morning and 8 o' clock evening, and providing nutrition for 6-15-year horseshoe crabs;
step five, after 16 years, adult horseshoe crab fish: changing the original 1-2 square meters of each culture unit into less than 1 square meter, placing adult horseshoe crabs in the newly-built culture units, reducing the range of motion of the culture units, carrying out seawater treatment on seawater in the culture units by using a water purifying device in the morning, the noon and the evening every day, and adding the corpses and marine worms of marine fishes into the culture units for providing nutrition 1-2 hours every day.
2. The method for rapid fattening cultivation of horseshoe crab for blood extraction according to claim 1, wherein: in the process of building a breeding place, a walking path channel is built between two adjacent breeding units, and the width of the walking path channel is 0.5-1 m.
3. The method for rapid fattening cultivation of horseshoe crab for blood extraction according to claim 1, wherein: in the fifth step, when the corpses of the marine fishes are fed, the corpses of the marine fishes need to be cut into blocks, and the size of each block is 2-3 square centimeters.
4. The method for rapid fattening cultivation of horseshoe crab for blood extraction according to claim 1, wherein: in the cultivation process, the interior of the cultivation unit is disinfected every 1-3 months.
5. The method for rapid fattening cultivation of horseshoe crab for blood extraction according to claim 1, wherein: in the fourth step, when the interior of the culture unit is oxygenated by the oxygen-increasing machine, the dissolved oxygen in the seawater of the culture unit is ensured to be 4mg/L-6mg/L.
