Description
Technical field
The present invention relates to Pelteobagrus fulvidraco cultivation field, more particularly to a kind of method of breeding graded Pelteobagrus fulvidraco fingerling.
Background technology
Pelteobagrus fulvidraco fine and tender taste, delicious flavour, protein abundance, fat content are low, and pierce without between flesh, and edible part is big,
Be difficult death, again can fresh aquatic food listing, it is deep to be favored by consumers in general.With growth in the living standard, consumer is to food product
The requirement of matter also more and more higher, it is increasing to the demand of Pelteobagrus fulvidraco.For a long time, the Pelteobagrus fulvidraco that people eat be mostly from
Natural to fish for, due to overfishing, wild Pelteobagrus fulvidraco resource is fewer and feweri, the phenomenon that occurs in that on market that supply falls short of demand.
The many raisers of Pelteobagrus fulvidraco nurture of fish fingerlings are to take summer flower and big specification to cultivate the mode for settling at one go, this mode
With certain advantage, its advantage is without fingerling frequently to be turned the pool, it is to avoid the damage of fish body, is easy to management, and save time province
Power, it is less demanding to managing；Have the disadvantage that pond utilization rate is low, fingerling quantity cannot be guaranteed, specification ginseng time is uneven, competing between fingerling
Fierceness is striven, the culture-cycle is long, reduce the turnaround speed of fund.
The content of the invention
Present invention seek to address that the deficiencies in the prior art, and a kind of method of breeding graded Pelteobagrus fulvidraco fingerling is provided.
The present invention for achieving the above object, is employed the following technical solutions：
A kind of method of breeding graded Pelteobagrus fulvidraco fingerling, concretely comprises the following steps：
(1) selection：
The Pelteobagrus fulvidraco spray for selecting physique healthy and strong, disease-free, specification neat is used as fingerling；
(2) fry culturing：
Selection area is 1500-1700m2Pond, 15 days before fingerling stocking, carry out preparation of ponds, sterilization, use 55-
70kg/700m2Quicklime slurrying full pool spilling head, shines the pool 7 days, and then water filling 0.8-1m, applies having for fermentation maturity in the 5th day after discharging water
Machine fertilizer, consumption are 55kg/ mus, cultivate sufficient wheel animalcule, small-sized cladocera opening biological feed；
By the spray of 2-3 ages in days with 150,000 tails/700m2Breeding density be put into the physical features of pond area 1.5% and relatively put down
Tan Zanyang areas cultivate, and after putting in a suitable place to breed, uniformly hang 8-10 gas head, oxygen supplement in 24 hours in Zan Yang areas；
Feed ten thousand tail of 2/100,000 tail of Ovum Anas domestica yolk and Trionyx sinensis Wiegmann powder 100g/10, add organic fat water, 4-7 days by fry
Full pond is distributed to, and fry length is cultivated to 3cm, as summer flower fingerling；
Nurturing period, weekly using a microorganism formulation, pond side weeds are periodically removed, keep water quality good, daily
Sooner or later the pool 2 times is patrolled, the activity of water colour and fish is observed, notes opening oxygen increasing equipment and the new water of filling, discovery Rana nigromaculata ovum, Herba Kyllingae,
Process in time；
(3) large size fingerling is cultivated：
Pelteobagrus fulvidraco summer flower fingerling length carries out a point pool cultivation, starts to feed commercial pellet feedstuff from after point pool to 3cm, first
First a bait table is taken on pond side, the area of every mu of pond bait table is 7m2, by bait table with bamboo stake or timber be fixed on from
Bottom of pond 15-20cm, then by bait feeding in bait table, tames 7 days in the bait table built during beginning, afterwards by normal throwing
Hello；The commercial feed for feeding is the pellet that protein content is 37%, coordinate 20% fish slurry, starts 10% by body weight
Amount feeds, and feeds 1 month, feeds daily 3 times, and feeding volume is gradually reduced afterwards, by the 4% of body weight, feeds 2 times daily, it is ensured that
Feed timing, positioning, quantitative and determine matter；
Want Jing often to clear up pond during daily management, per two weeks with lime disinfection 1 time, June and July every
Water filling in 10-15 days 1 time, changes to new water 10-15cm every time, and August part changed water 1 time every 10 days, changes water 10-15cm every time, keeps
In 1.5m, pond is equipped with oxygen increasing equipment to the depth of water, and fine day noon opens increasing and supports 1 hour of machine, makes pond water-soluble oxygen in more than 5mg/L,
In breeding process, periodic adjustment water quality simultaneously determines pond water quality every 2 Mondays time.
During fry culturing when the water filling of pond, water inlet arrange 60 mesh sieve thin,tough silk filtered, in case wild fisheses and
Fish roe is entered.
The microorganism formulation used during fry culturing is the clear biological preparation of green promise, and consumption is 35g/ mus.
The invention has the beneficial effects as follows：The present invention cultivates Pelteobagrus fulvidraco by the way of breeding graded large size fingerling, favorably
In the growth and survival rate that improve small individual, it is to avoid the potential unfavorable factor of intraspecies combat, it is a kind of more economical, efficiently
With the type of rearing of health.
