The present invention relates to a kind of methods for improving freshwater shrimp egg laying rate of red swamp, and first using cylindrical pvc pipe as artificial fish nest, the horizontal bottom in Cultivation container, then the long 3cm or more of selection body, appendage are complete, and active shrimp of swimming is placed in Cultivation container as parent;It when water temperature reaches 10-15 DEG C, starts to warm up, primary 1-3 DEG C of heating, heating in every 1-3 days once, until water temperature rises to 18-28 DEG C, is then kept the temperature;The immunopotentiator that 3-10% is added into basal feed obtains mixed feed, and the feeding volume of mixed feed is the 3-5% of shrimp gross weight, feeds within one day 2 times, once in the morning and once at night, feeds 40-60 days.The present invention can effectively solve the problem that the freshwater shrimp female parent speed of growth is slow, the death rate is high, the development of ovary is slow, egg laying rate of red swamp is low in traditional breeding process.The method of the present invention is simple, at low cost, can greatly improve close shrimp survival rate, and freshwater shrimp egg laying rate of red swamp can be increased to 90% or more.
Description
Technical field
The present invention relates to a kind of methods of aquatic livestock parent culture, belong to technical field of aquaculture.
Background technique
Freshwater shrimp (Macrobrachium nipponense) scientific name Macrobrachium nipponensis also known as river prawn, are under the jurisdiction of Malacostraca, ten
Sufficient mesh, Natantia, Palaemonidae, pond crayfish category.Macrobrachium nipponensis meat flavour is fresh and tender, full of nutrition, the deep favor by consumer.At me
There are rule on the ground such as state Jiangsu, Anhui, Shanghai, Zhejiang, Fujian, Jiangxi, Guangdong, Hunan, Hubei, Sichuan, Hebei, Henan, Shandong
Mould cultivation, in Yangtze River Delta especially southern area of Jiangsu Province, shrimp culture industry, which has become, realizes increasing peasant income, growth of agricultural efficiency, promotees
Into the mainstay industry of Fisheries Development.Zhenjiang, Jiangsu Danyang City shrimp culture family shrimp culture benefit average yield per mu value in recent years
7000 yuan or more are reached, the output value of even as high as 12000 yuan/mu in 2016.
During traditional shrimp culture, with the increase of shrimp culture density, breeding environment is worsening, causes to support
The freshwater shrimp female parent speed of growth is slow during growing, and the death rate is high, and the development of ovary is slow, and egg laying rate of red swamp is low, constrains the kind of freshwater shrimp
Industry development.Therefore, cultivating the female parent that the speed of growth is fast, individual is big, ovary is full, egg laying rate of red swamp is high is the development of freshwater shrimp kind industry
Urgent problem to be solved in the process.
Summary of the invention
Present invention aim to address the freshwater shrimp female parent speed of growth in the prior art is slow, the development of ovary is slow, female shrimp
The low problem of egg laying rate of red swamp provides a kind of method for improving freshwater shrimp egg laying rate of red swamp.
Technical solution
A method of freshwater shrimp egg laying rate of red swamp is improved, is included the following steps:
(1) artificial fish nest is established: using cylindrical pvc pipe as artificial fish nest, the horizontal bottom in Cultivation container;
(2) selecting parent shrimps: the long 3cm or more of body is chosen, appendage is complete, and active shrimp of swimming is placed on step (1) as parent
Cultivation container in;
(3) temperature programming: when water temperature reaches 10-15 DEG C, starting to warm up, primary 1-3 DEG C of heating, heating one in every 1-3 days
It is secondary, until water temperature rises to 18-28 DEG C, then keep the temperature;
(4) feedstuff feeding: the immunopotentiator of 3-10% is added into basal feed, obtains mixed feed, mixed feed
Feeding volume be shrimp gross weight 3-5%, feed within one day 2 times, once in the morning and once at night, feed 40-60 days.
Further, in step (1), the long 10-25cm of pvc pipe, internal diameter 4-6cm.
Further, in step (1), the placement density of the pvc pipe is 10-15 root/m2。
Further, in step (2), Qin Benzhong, female and male ratio 3:1.
Further, in step (4), the immunopotentiator is grouped as by the group of following parts by weight: 20-50 parts viscous more
Sugar, 30-60 parts of weight ratio are the Radix Isatidis of 1:1 and the mixture of astragalus polyose, 10-30 parts of Yolk immunoglobulin.
Beneficial effects of the present invention:
The present invention provides a kind of method that can improve freshwater shrimp egg laying rate of red swamp, it is female to can effectively solve freshwater shrimp in traditional breeding process
The property problem that parent's speed of growth is slow, the death rate is high, the development of ovary is slow, egg laying rate of red swamp is low.The method of the present invention is simple, at low cost,
Close shrimp survival rate can be greatly improved, freshwater shrimp egg laying rate of red swamp can be increased to 90% or more.
Specific embodiment
The following describes the present invention in detail with reference to examples.But the scope of the present invention is not by any form of embodiment
On limitation.
In following embodiments,
Close shrimp survival rate=male and female freshwater shrimp initial male and female freshwater shrimp of sum ÷ that finally survives puts total quantity × 100% in a suitable place to breed
Female shrimp egg laying rate of red swamp=oogenesis freshwater shrimp quantity ÷ female freshwater shrimp quantity × 100%.
Embodiment 1
