Embodiment 1

[0052] A method for cultivating squid seedlings, comprising the following steps:

[0053] (1) Production facilities and preliminary preparations

[0054] a. Broodstock rearing and spawning facility preparation

[0055] Parent pool is 30 m 2 For the above circular or square pools, the depth of the pool is 2 m; the bottom of the pool is covered with a layer of fine sand with a thickness of 3 cm; each pool is symmetrically set up with 2 water inlet pipes and 1 outflow port; conventional heating pipes are installed; In the living area and the spawning area, one air stone is placed per square meter in the living area, and no air stone is placed in the spawning area; a number of bamboo poles are placed across the pool wall in the spawning area, and the distance between the bamboo poles is 1 m. Bamboo poles are used to hang the attachment base, and one attachment device is hung per square meter; to simulate the spawning environment of squid in the natural sea area, let the squid la...

Embodiment 2

[0086] (1) Production facilities and preliminary preparations

[0087] a. Broodstock rearing and spawning facility preparation

[0088] Parent pool is 30 m 2 For the above circular or square pools, the depth of the pool is 2.5 m; the bottom of the pool is covered with a layer of fine sand with a thickness of 5 cm; each pool is symmetrically set up with 2 water inlet pipes and 1 outlet; conventional heating pipes are installed; In the living area and the spawning area, one air stone is placed per square meter in the living area, and no air stone is placed in the spawning area; a number of bamboo poles are placed across the pool wall in the spawning area, and the distance between the bamboo poles is 1.3 m. Bamboo poles are used to hang the attachment base, and one attachment device is hung per square meter; to simulate the spawning environment of squid in the natural sea area, let the squid lay fertilized eggs on the attachment device;

[0089] b. Necessary facilities for coll...

Abstract

The invention relates to a method for cultivating squid seedlings, which belongs to the technical field of aquatic product cultivation. The method utilizes shrimp ponds to cultivate squid seedlings, and manages them according to the characteristics of squid larvae development, including preliminary preparation, brood spawning, fertilized egg collection, Incubation, biological bait cultivation, stage I cultivation of larvae, stage II cultivation of larvae, stage I cultivation of seedlings, stage II cultivation of seedlings, food domestication and other steps; Economic benefits, suitable for popularization and application.

Description

technical field [0001] The invention relates to a method for cultivating squid seedlings, in particular to a method for cultivating squid seedlings in shrimp ponds, and belongs to the technical field of aquatic product cultivation. Background technique [0002] Squid, also known as squid, cuttlefish or cuttlefish, is an animal of the mollusk phylum cephalopod squid. The flesh of squid is white and tender, and is very nutritious. Every 100 grams of fresh squid contains 17 grams of protein, 1.7 grams of fat, 85 mg of calcium, 198 mg of phosphorus, 1.1 mg of iron, and 85 kcal of heat. Calorie food is deeply loved by people. [0003] There are many kinds of squid, up to more than 350 kinds, among which squid, squid, and tiger squid are very common seafood ingredients. Mansoni squid was once one of the four major targets of marine fishery in my country, and it is a precious fishery resource in China. However, Mansoni squid is precocious, small in size (50g / piece), and other unf...
