Embodiment 1

[0022] Embodiment 1: the establishment of cultivation condition

[0023] 1. Conditions of the breeding pond

[0024] The depth of the pool is 1.2-1.8m, and the area is preferably 0.5-2 mu. If the water temperature exceeds 33°C during the stocking period, it is necessary to spread a sunshade net on the top of the greenhouse to avoid high temperature and strong light, and the surrounding environment should be kept as quiet as possible.

[0025] 2. Pre-stocking work

[0026] Before the tabby squid is stocked (30 days), the breeding pond is cleaned and disinfected. Generally, the water is drained to 30-40cm. Quicklime can be used for clearing the pond. Mu is 40-50Kg / mu. On the one hand, it is to kill harmful organisms, and on the other hand, it removes sapropel at the bottom of the pool to improve water quality and bottom quality. After the clear pond is treated, do a good job of water storage 15 to 20 days before stocking, and cultivate basic bait (inoculate mysis or common s...

Embodiment 2

[0040] The method with embodiment 1 is basically the same, and difference is only 0.8 mu of cultivation area, and before the tabby squid seed is put in a suitable place to breed, every mu puts in a suitable place to put 120,000 tail common shrimp seedlings in a suitable place as the reserve live bait of squid. The size of the tiger squid seedlings is: select healthy, vigorous tiger squid larvae with a carcass length of 5 cm; the breeding density is 20 / m 2 During the breeding period, the water temperature is controlled at 27-32°C, the salinity is controlled at 26-33‰, and the suitable pH is 7.8-8.2. After about 130 days of breeding, the tiger squid reached the commercial specification (average body weight 0.456kg), and the breeding survival rate was 59.6%.

Embodiment 3

[0042] The breeding method with embodiment 1 is basically the same, and difference is 0.7 mu of breeding area, and the tiger squid seed size is: select health, vigor is good, the tiger squid larvae of carcass length 5cm; Breeding density is 30 / m 2 During the breeding period, the water temperature is controlled at 27-33°C, the salinity is controlled at 26-33, and the suitable pH is 7.8-8.3. After about 130 days of breeding, the tiger squid reached the commercial specification (average body weight 0.506kg), and the breeding survival rate was 61.6%.

[0043] Show by above example, the present invention is a kind of survival rate height, grows fast, manages easily, and stable yield and high-yield tabby squid breeding method.

Abstract

The invention discloses a method for breeding sepia pharaonis in a greenhouse. According to the method, breeding conditions are controlled, breeding management is carried out as follows: water temperature is controlled to be 23-33 DEG C, salinity is controlled to be 24-30, the transparency of pond water is controlled to be 40-60 cm, dissolved oxygen is not lower than 5 mg/L, ammonia nitrogen content is not higher than 0.1 mg/L, meanwhile, by the characteristics that the temperature and humidity of the greenhouse can be regulated, the density of the sepia pharaonis and the size and feeding amount of baits are controlled, mutual killing of the sepia pharaonis in a breeding process is relieved and the like, the sepia pharaonis can grow fast and appear on the markets early, and good advantagesare achieved. Therefore, the method for breeding the sepia pharaonis in the greenhouse is a sepia pharaonis breeding method which is high in rate of survival, high in growing speed and easy to operate, and is stable and high in yield.

Description

technical field [0001] The invention belongs to the technical field of aquatic animal breeding, and in particular relates to a method for cultivating tiger squid in a greenhouse. Background technique [0002] Tiger squid (Sepia pharaonis) belongs to Mollusca, Cephalopoda, Sepiida, and Sepiidae. It is the main squid fishery resource in my country. High in protein and low in fat, it is a kind of seafood that the people like very much. However, due to overfishing and environmental deterioration in the past 30 years, its resources have been declining day by day. [0003] Since 2014, the inventor's team has carried out research on the artificial breeding and breeding of tiger squid. In the research, it is found that the tiger squid is large, up to 4kg, and grows fast. It can grow to 0.5kg after 4 months of breeding. It is an economical cephalopod with great breeding prospects. The breeding of tiger squid seedlings is carried out from April to May every year, and its breeding sta...
