Abstract
The invention discloses a kind of live bait feeding methods for improving dragon design spot spray seedling survival rate, its method is mainly first first to install artemia incubator in dragon design spot spray seedling pool side, a kind of automatic bait-laying device for fish is installed again by incubator, it is automatically flowed into spray Miao Chi by artemia from incubator using siphon principle, finally using ingest phototaxis the characteristics of, lure spray seedling to ingest.The survival rate of dragon design spot spray seedling can be increased to 70% or more by this method.
Description
Technical field
The present invention relates to aquaculture field, specially a kind of dragon design spot spray seedling feeding method.
Background technique
Squab fry is known as fish fry, spray, summer flower, and adaptive capacity to environment is poor, individual small, disease-resistant management energy
Power is weaker, if mismanagement, feeding is improper can cause its death, therefore, under whether fry rearing successful and spray fry
Survival rate behind pond has direct relation.
Dragon design spot, scientific name worm line river blackfish also known as black auspicious cod are the famous carnivorous fresh water warps of one kind for originating in Australia
Ji fish.Erbium living is liked, density is big, is very suitable to intensive culture.Tu Chi, which is cultivated, can breed many natural live baits, such as take turns
Worm, cladocera, but type and specification are inconsistent, and especially in dragon design spot spray seedling cultivating process, some live erbium individual too
Greatly, spray seedling can be attacked, harm is generated to spray seedling, some are lived, and erbium is not agreeable to the taste, and fry can not ingest consequently only that a small amount of type
Agreeable to the taste live bait can just be eaten by spray seedling with specification, and leading to the survival rate of prior art interbedded water flower seedling is only 2% -3%.
Summary of the invention
It is an object of the invention to solve live bait type, cause diversified in specifications in dragon design spot spray seedling cultivating process, live bait food
The problem for lowly causing dragon design spot spray seedling survival rate low with rate provides a kind of live bait for improving dragon design spot spray seedling survival rate
Feeding method.
To achieve the above object, the invention provides the following technical scheme: the size and specification of artemia can be used as agreeable to the taste bait,
Any aggressiveness will not be generated to spray seedling, therefore, in the present invention, we select artemia as the bait of dragon design spot spray seedling
Material, but in view of artemia hatching needs to carry out in the seawater, if the direct full pool spilling head of artemia can be wasted to feed spray seedling
A large amount of artemias, while the artemia after hatching can cause death because of that can not rapidly adapt to fresh water environment, the corpse after death is rotten
It loses, further pollutes water quality.And the travelling ability of dragon design spot spray seedling is weak, can not be moved about at a distance, can only ingest certainly
The work erbium of short distance around body.Therefore it is contemplated by the invention that first installing several artemia incubators in dragon design spot spray seedling pool side, incubates
The face dragon design spot spray Miao Chi certain distance need to be higher than by changing case height, and the inside is put into oxygenate apparatus, installs one again by each incubator
Kind of automatic bait-laying device for fish, the bait-laying device for fish use siphon principle, using with and using ingest phototaxis the characteristics of, can pinpoint just
Bait closely is provided for spray seedling for 24 hours, improves the survival rate of spray seedling, it is contemplated that survival rate may be up to 70% or more.
Specifically, a kind of live bait feeding method improving dragon design spot spray seedling survival rate, includes the following steps.
(1) artemia is hatched: the set-point of multiple artemia incubators is arranged in cultivation pool side, the height of incubator bottom is from dragon
The line spot face spray Miao Chi is not less than 50cm, and suitable quantity of water, sea salt and artemia are added in incubator, and control artemia amount is 10g/L, connects
The gentle stone of top hose, is oxygenated artemia.
(2) automatic bait-laying device for fish is installed: taking a sufficiently long hollow hoses again, artemia incubator is inserted into one end, another
Circular arc type is formed in end insertion dragon design spot spray seedling culture pond, under the action of siphon principle, artemia will be from higher end
Incubator is slowly flowed into along hollow hoses in dragon design spot spray Miao Chi.
(3) become light bait throwing in: a weak light lamp is installed above adjacent automatic bait-laying device for fish, outer layer adds lampshade, avoids
Light direct projection opens weak light lamp sooner or later daily in advance, lures below spray Miao You to weak light lamp, to guarantee that spray seedling pinpoints
There is bait edible for 24 hours.
Preferably, a kind of live bait feeding method of above-mentioned raising dragon design spot spray seedling survival rate, in the step (1)
Artemia incubator placed every 2-4m.
Preferably, a kind of live bait feeding method of above-mentioned raising dragon design spot spray seedling survival rate, in the step (2)
Hollow hoses internal diameter between 1.5cm -3cm, internal diameter is too small, and artemia easily blocks hose, and internal diameter is excessive, and siphonic effect is not
Obviously.
Preferably, a kind of live bait feeding method of above-mentioned raising dragon design spot spray seedling survival rate, in the step (3)
Weak light lamp power be no more than 40w.
Beneficial effect
1. being bait by selecting artemia, not only solves the problems, such as to ingest in dragon design spot spray seedling cultivating process non-uniform, also solve
Bait of having determined attacks the problem of dragon design spot spray seedling.2. adjustable point is quantitative and guarantees that dragon design spot spray seedling has live bait edible for 24 hours, keep away
Exempt from generation bait waste and causes water pollution.3. improving the survival rate of dragon design spot spray seedling, survival rate may be up to 70% or more,
It is with good economic efficiency.
