Embodiment 1

[0025] A kind of scientific releasing method of verrucous snout clam worm seed, comprises the following steps:

[0026] (1) Site selection for release: choose mangrove tidal flats.

[0027] (2) The source and specification of released seedlings: the parent of Nereis verrucosus was selected to artificially breed seedlings in the adjacent nursery. The total length is 3-4cm, and it develops to 30-40 ganglia.

[0028] (3) Health check of released seedlings: Take 5% of the total number of released seedlings for health inspection to ensure that the seedlings are healthy, vigorous, complete with warts and feet, free from disease and injury, and have uniform specifications.

[0029] (4) Counting method of released seedlings: adopt the sampling counting method, customize a plastic tray with a length of 60cm, a width of 30cm, and a height of 5cm, shovel into the cultivation bed base with a thickness of just 3-5cm from the nursery pond to cover the entire tray, and pour it into 80 mesh ...

Embodiment 2

[0034] A kind of scientific releasing method of verrucous snout clam worm seed, comprises the following steps:

[0035] (1) Site selection for release: choose a river estuary wetland with flat terrain and rich in organic matter.

[0036] (2) The source and specification of released seedlings: select ponds to cultivate and develop until 30-40 larvae are transplanted to wetlands for stocking.

[0037] (3) Health check of released seedlings: Take 5% of the total number of released seedlings for health inspection to ensure that the seedlings are healthy, vigorous, complete with warts and feet, free from disease and injury, and have uniform specifications to ensure the health level of released seedlings good.

[0038] (4) Counting method of released seedlings: adopt the sampling counting method, customize a plastic tray with a length of 60cm, a width of 30cm, and a height of 5cm, shovel into the cultivation bed base with a thickness of just 3-5cm from the nursery pond to cover the...

Abstract

The invention relates to a scientific releasing method of juvenile tylorrhynchus heterochaetus. The scientific releasing method of the juvenile tylorrhynchus heterochaetus comprises the following steps: (1) releasing site selection; (2) source and specification of released juvenile tylorrhynchus heterochaetus; (3) health examination of the released juvenile tylorrhynchus heterochaetus; (4) releasing time selection; (5) counting of the released juvenile tylorrhynchus heterochaetus; (6) transportation and releasing of the released juvenile tylorrhynchus heterochaetus; (7) effect evaluation of the released juvenile tylorrhynchus heterochaetus. The method accords with the biological and physiological ecological habits of the released juvenile tylorrhynchus heterochaetus; the operation method is simple, reasonable and scientific; the population quantity of the tylorrhynchus heterochaetus is restored effectively; and the method exerts greater economic, social and ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of proliferation and releasing of aquatic species, and in particular relates to a scientific method for releasing clam worm seedlings. Background technique [0002] Wart-nose Nereis ( Tylorrhynchus heterochaetus ), belonging to the phylum Annelids, Polychaetes, Wandering Orders, Nereisidae, Nereis genus, commonly known as grass insects and lizards, usually inhabiting coastal or estuary shoals, mainly produced in Zhejiang, Guangdong and Fujian provinces . It has the characteristics of high protein, high fat, a complete range of amino acids, and rich content of essential amino acids. Although it looks ugly, the meat is tender and nutritious. It can be called "the Cordyceps on the river". "Liu Li" is used as both food and medicine. It is not only delicious, but also can be used as a traditional Chinese medicine, which has the effect of reducing swelling and replenishing qi. Huang Tingbiao once praised it in ...
