Method for harvesting and temporarily culturing sepia esculenta in cuttlefish-shrimp polyculture pond

Abstract

The invention provides a method for harvesting and temporarily culturing sepia esculenta in a cuttlefish-shrimp polyculture pond. The method comprises steps: selecting a common ground cage for capturing prawns and a grading catching ground cage used for a prawn-crab polyculture pond; using the grading catching ground cage to catch prawns, and then using the common ground cage to capture cuttlefishes; after the cuttlefishes are caught, oxygenating and transporting the cuttlefishes with water; preparing a buffer pond and a temporary culturing pond; putting the cuttlefishes transported with water in the buffer pond to adapt for 2-3 hours, and transferring the cuttlefishes with water to the temporary culturing pond to temporarily culture; in temporary culturing, covering a blackout cloth on the temporary culturing pond, in the first week of temporary culturing, feeding fresh and alive crablats, in the second week, feeding fresh and alive palaemon carinicauda, after two weeks, feeding iced fresh small trashes; after 20-30 days of temporary culturing, using the sepia esculenta for live selling. The survival rate of the sepia esculenta after temporary culturing can reach higher than 90%. The method completely realizes live selling of the sepia esculenta, and improves economic benefits of the sepia esculenta cultivation.

Description

technical field

[0001] The invention relates to a method for harvesting golden squid, in particular to a method for harvesting and temporarily cultivating golden squid in a mixed culture pond of prawns. Background technique

[0002] In the prior art, the golden squid is suitable for the mixed culture of thieves and shrimps, but the body of the golden squid is soft, and the forehead sword of the prawns is easy to stab the golden squid when it is harvested; moreover, when the golden squid is harvested, it will spray a large amount of ink, which will not only anesthetize itself, but also The body will become weak, which greatly affects the sales of live golden squid. If measures can be taken to ensure the listing of live products, the market and price will be very impressive. However, in the method of harvesting the golden squid currently adopted, the golden squid is seriously injured, and the impact of inkjet is added, and the mortality rate is as high as 80%, which directly ...
