Embodiment 1

[0020] In February 2017, the early spring water flower seedling cultivation test of heterogeneous gibel carp "Zhongke No. 3" was carried out in the 2 seedling cultivation ponds of Changtai seedling cultivation base. The total area of ​​the pond is 1500 m 2 . Install a microporous aeration pipe parallel to the short side of the pond at intervals of 1.5 to 2.0 m along the long side of the pond at the bottom of the cultivation pond, the length of which is equal to the short side of the bottom of the pond, and connect it to the Roche blower through a connecting pipe , using the upward lifting force of the oxygen-increasing gas, it can effectively slow down the sedimentation of the particulate bait, make it dispersed and suspended in the water body, and prolong the feeding time of the larvae. , a total of 3.75 million early spring water flower seedlings of heterogeneous gibel carp "Zhongke No. 3" were stocked, and the average stocking density was 2,500 fish / m 2 . The stocking den...

Embodiment 2

[0026] At the end of February 2017, the early spring water flower seedling cultivation test of heterogeneous gibel carp "Zhongke No. 3" was carried out in a seedling cultivation pond in the Shunchang seedling demonstration base. The total area of ​​the pond is 1400 m 2. Install a microporous aeration pipe parallel to the short side of the pond at intervals of 1.5 to 2.0 m along the long side of the pond at the bottom of the cultivation pond, the length of which is equal to the short side of the bottom of the pond, and connect it to the Roche blower through a connecting pipe , using the upward lifting force of the oxygen-increasing gas, it can effectively slow down the sedimentation of the particulate bait, make it dispersed and suspended in the water body, and prolong the feeding time of the larvae. , a total of 4.2 million early spring water flower seedlings of heterogeneous gibel carp "Zhongke No. 3" were stocked, and the average stocking density was 3,000 fish / m 2 . The s...

Abstract

The invention discloses a method suitable for cultivating carassius auratus gibelio 'Zhongke No. 3' early spring fries. The method comprises the following steps of mounting a micropore aerator pipe atthe bottom of a fry cultivation pond, and performing standard coarse cultivation on the carassius auratus gibelio 'Zhongke No. 3' early spring fries in three stages by taking particle fermented fishpaste and fry puffed micro-particle compound feed as main baits. Compared with a traditional fertilizer water and soybean milk fry cultivation method, the cultivation method provided by the inventioncan solve the problems that pond plankton bait is difficult to cultivate, large-scale supply cannot be guaranteed, the fry cultivation survival rate is low, and the cultivation density is limited in early spring low-temperature rainy weather, and the unit yield and survival rate in the carassius auratus gibelio 'Zhongke No. 3' early spring fry cultivation are effectively increased; and the growth,the stress resistance and the fry quality of early spring fries are obviously improved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for cultivating early spring seedlings of heterogeneous gibel crucian carp "Zhongke No. 3". Background technique [0002] The heterogeneous gibel carp is one of the excellent varieties of crucian carp that has been cultivated on a large scale in my country and has stable characteristics. "Zhongke No. 3" is its third-generation new variety. It grows fast, has a good body shape and good body color, and has good market acceptance. Degree, good breeding benefits. However, due to its fast growth rate and relatively large daily food intake, once the bait and nutrition are insufficient in the early seedling cultivation stage, it will lead to problems such as slow seedling growth, high morbidity rate, and low survival rate. Therefore, the standard coarse breeding of "Zhongke No. 3" seedlings in early spring has greatly affected the time for adult fish to reach th...
