Abstract

The invention relates to a method for quickly and efficiently detecting a sepiella maindroni population by using environmental DNA to detect the sepiella maindroni population without damaging the environment and the species population. Collected eDNA samples are taken from the soil, sediment and water and the like, no environmental burden is caused to detection points, and no adverse influence iscaused to the living environment of the species. Special primers and probes are utilized to accurately, quickly and efficiently detect the DNA of sepiella maindroni, the efficiency and accuracy of thedetection are improved, and the detection cost is reduced. Compared with a field survey method used by the transmission of the sepiella maindroni population distribution detection, the method has theadvantages of saving time and labor, being low in cost and efficient and causing no harm to target species and no damage to a survey point ecosystem.

Description

technical field [0001] The invention relates to a method for detecting the population of squid mansoni, in particular to a method for detecting the population of squid mansoni quickly and efficiently by adopting environmental DNA without damaging the environment and species population. Population method. Background technique [0002] Sepiella japonica is an annual medium-sized squid. Cephalopoda, Sepiaceae. Commonly known as cuttlefish, it grows fast and has delicious meat. It is a popular seafood food in the market. Mansoni squid is mainly distributed in the Yellow Sea and East China Sea in my country, and is a close-range migratory species. In the coast of my country, squid mansoni is an economical cephalopod with abundant resources and good yield. The needleless squid is full of treasures, and has high edible and medicinal value. It was one of the "four sea products" in my country in the 1970s and 1980s. Its annual output can reach tens of thousands of tons, of which...
