Problems solved by technology

Adults and larvae of golden squid like to eat live bait, and the water in the hatching pool of fertilized eggs must be clear, which greatly limits the promotion of this species. The society urgently needs a high-yield, efficient, and environmentally friendly golden squid brood domestication and seed breeding model to solve the problem of golden squid. Feed and water quality problems during broodstock domestication and seed breeding

Embodiment 1

[0063] Embodiment 1, a method for domestication and early emergence of golden squid broodstock, the steps are as follows: (1) selection and transformation of the domestication pond; the selection and transformation of the domestication pond is an ordinary earthen pond with an area of ​​100 m 2 , with a water depth of 2m, a double-layer thermal insulation greenhouse is built above the earthen pool, and stainless steel heating pipes and microporous oxygenation pipes are laid on the bottom of the pool.

[0064] (2) Selection and transformation of the hatching pool; the selection and transformation of the hatching pool mentioned above is a shrimp and crab nursery workshop that is idle in autumn and winter, and the area of ​​the cement pool is 20m 2 , lay a layer of 5 cm thick fine sand at the bottom of the pool, and the fine sand particle size is 0.1mm.

[0065] (3) White prawns reproduce on their own; From September to October, white prawns with a weight of 2 g are stocked in the...

Embodiment 2

[0086] Embodiment 2, a kind of golden cuttlefish body domestication and early emergence method, its steps are as follows:

[0087] (1) Selection and transformation of the domestication pond; the selection and transformation of the domestication pond is that the domestication pond is an ordinary earthen pond with an area of ​​200 m 2 , with a water depth of 3 m, a double-layer thermal insulation greenhouse is built on the earthen pond, and stainless steel heating pipes and microporous oxygenation pipes are laid on the bottom of the pond.

[0088] (2) Selection and transformation of the hatching pool; the selection and transformation of the hatching pool mentioned above is a shrimp and crab nursery workshop that is idle in autumn and winter, and the area of ​​the cement pool is 60 m 2 , A layer of fine sand with a thickness of 10 cm and a grain size of 1.0 mm is laid on the bottom of the pool.

Embodiment 3

[0110] Embodiment 3, a kind of golden cuttlefish domestication and early emergence method experiment:

[0111] Experiment time and address: 2017~2018 in Dabanqiao earth pond and indoor seedling cultivation workshop in Lianyun District.

[0112] Experimental process: On September 15, 2017, white prawns with a weight of 2.5~3.5 g were stocked in the domestication pond, and the density was 4 fish / m 2 , making it self-propagating as bait for domestication of golden squid, during which time it was fed with fortified bait for white prawns. The composition of the bait is as follows:

[0113] Fish paste protein powder 17.9 % mixed oil 5 %

[0114] Russian White Fish Meal 15 % Fortified Fish Oil 3 %

[0115] Fermented soybean meal 15 % Multivitamin for shrimp 3 %

[0116] Squid powder 8% Compound enzyme preparation 3%

[0117] Selenium-enriched yeast 8 % Vitamin C polyphosphate 0.5 %

[0118] Secondary Powder 10 % Vitamin E Acetate 1 %

[0119] Fermented Corn 5 % Antimicrobial Pept...

Abstract

The invention provides a method for parent raising and training and in-advance fry emergence of sepia esculenta. The method includes the steps of raising and training pond selection and modification,hatching pond selection and modification, palaemon carinicauda autonomous breeding, parent selection and stocking, ovum collecting, fertilized ovum temporary raising and concentrated hatching, opossumshrimp autonomous breeding and young sepia esculenta culture. An shrimp and crab fry culturing workshop and an available breeding earthen pond in autumn and winter are sufficiently utilized, the source of parents during artificial culturing of sepia esculenta is limited, the ecological complementation between the parents of sepia esculenta and palaemon carinicauda, young sepia esculenta and opossum shrimps is used for conducting parent raising and training and young sepia esculenta culturing, a hatching pond can meet the demand of fertilized ovum hatching for water quality, and technical operation is easy. The breeding and growing capacity of the palaemon carinicauda and opossum shrimps is quite high, continuous breeding can be realized in the whole year, the demand of the parents of thesepia esculenta and the young sepia esculenta for live baits is met, the targets of high yield, high efficiency and environmental protection are realized, and sufficient fry can be provided when breeding is conducted in the sepia esculenta pond.

Description

technical field [0001] The invention relates to a method for broodstock breeding and seed breeding of aquatic animals, in particular to a method for broodstock domestication and early emergence of golden squid. Background technique [0002] Artificial breeding of golden squid has just started in northern provinces such as Liaoning, Shandong and Jiangsu, and the supply of golden squid seed has greatly restricted the smooth progress of golden squid breeding. The northern provinces are cold in winter, and often encounter irregular or / and long-term low temperatures, and the seawater temperature can drop to about 0°C, which often makes it difficult for farmed golden squid to survive the winter successfully. If measures can be taken to ensure its safe overwintering, the seedlings will emerge in advance around the Spring Festival, which will be very profitable. Under normal circumstances, golden squid seedlings can only be caught in June to July, and the period for breeding in pon...
