Embodiment 1

[0035] Embodiment 1, a kind of northern small shed culture method of tabby squid, its steps are as follows:

[0036] (1) selection and transformation of the earthen pond; the earthen pond is made as a rectangle, with an area of ​​20 mu, and the aspect ratio=4, and an earthen pond A of 1 mu is surrounded by an earth dam on the short side side, and the water depth of the earthen pond A is 2 meters, and the bottom of the pond and surrounding areas are covered with a A layer of geotextile, covered with a 2-meter-high double-layer insulation shed above, earth pond A communicates with the remaining earth pond B through a gate, keep the gate closed, excavate a 2-meter-wide and 1-meter-deep ring ditch around the earth pond B, inside the ring ditch The water depth is maintained at 2.5 meters;

[0037] (2) Putting mysis and white shrimp with eggs; when the surface water temperature of pond B in the earthen pond is 10-11°C in spring, put 10,000 to 20,000 mysis / mu and white shrimp with eg...

Embodiment 2

[0043] Embodiment 2, a kind of northern small shed culture method of tabby squid, its steps are as follows:

[0044] (1) Selection and transformation of the earthen pond; the earthen pond is set as a rectangle with an area of ​​50 acres and an aspect ratio ≥ 4, and an earthen pond A of 1.5 mu is surrounded by an earth dam on one side of the short side, and the water depth of the earthen pond A is 2.5 meters. A layer of geotextile, covered with a 3-meter-high double-layer insulation shed above, earth pond A communicates with the remaining earth pond B through a gate, keep the gate closed, excavate a 3-meter-wide and 1.5-meter-deep ring ditch around the earth pond B, inside the ring ditch The water depth is maintained at 3.5 meters;

[0045] (2) Putting mysis and white shrimp with eggs; when the surface water temperature of pool B in the earthen pond is 11-12°C in spring, put 10,000 to 20,000 mysis / mu and white shrimp with eggs 1-2 catties / mu at one time , to carry out polycultu...

Embodiment 3

[0052] Embodiment 3, in the northern small shed culture method of a kind of tiger squid described in embodiment 1 or 2, the preparation method of bait for mixed cultivation of mysis and white prawns in step (2) is as follows: first corn flour, soybean meal , peanut meal, bran, mixed oil and yeast fermentation powder ingredients, mixed and crushed, add water and mix well, ferment in the fermentation tank for 2-3 days, and then mix with small miscellaneous fish, squid powder, yeast powder, aquatic microecological preparations, The compound enzyme preparation is mixed with calcium dihydrogen phosphate, and put into a soft bait granulator for granulation. The bait particles are 0.1-0.5 cm long and 0.1-0.4 cm in diameter.

Abstract

The invention relates to a method for cultivating tiger squid in a small northern shed. The method includes selection and transformation of earthen ponds, feeding mysis and white prawn with eggs, feeding bait for mixed culture of mysis and white shrimp, and throwing fertilized eggs of tiger squid , Cultivation of young crows, polyculture of prawns in earthen ponds and polyculture of prawns with bait. The method of the invention introduces mysis, white shrimp and cuttlefish into the same culture pond, improves the stability of the ecosystem, and effectively controls the disease of white shrimp At the same time, make full use of the water body, improve the productivity of the water area, and increase economic benefits. It is suitable for promotion in outdoor shrimp ponds in northern China and promotes the industrialization of northern tiger squid farming.

Description

technical field [0001] The invention relates to a culture mode, in particular to a culture method for cultivating tiger squid in a northern earthen pond. Background technique [0002] In our country, the shrimp industry has long been an important pillar industry of the mariculture industry, which has brought very obvious economic and social benefits to our country. However, since 1993, shrimp diseases once brought China's shrimp farming industry into a slump. In the northern part of China, there are more and more diseases in the culture of Penaeus prawn and Litopenaeus vannamei, the size of commercial shrimp is too small, the pollution of farming is becoming more and more serious, the aquaculture area of ​​outdoor earthen ponds is shrinking day by day, and a large number of outdoor earthen ponds are in a state of loss. Tiger squid in subtropical and tropical sea areas are benthic cephalopods. They like to lie on the bottom of the pond after feeding, and use most of their en...
