Description
Technical field
The present invention relates to mariculture technology, especially a kind of reinforced cultivating side for improving Sepiella maindroni reproductive capacity
Method.
Background technology
In recent years, the development of Sepiella maindroni aquatic breeding proposes demand to embryonated egg quantity, but due to Man without
Sepia andreana fish brood amount is smaller, and a cuttlefish can only typically produce hundreds of embryonated eggs, therefore improve the female body of Sepiella maindroni unit
Reproductive capacity it is significant.
In the prior art, Cultivating techniques are a lot, such as a kind of precision pond culture method for sepiella maindroni de Rochebrune,
CN103392641A, bottom of pond 75,000 grams/acre of lime waters of splashing carry out pasteurised completely, and kill harmful organisms, pond after sterilization
And black thickness mulch film is all spread around pond, and an aerator is equipped with, breeding density is depending on seed Individual Size, and trunk is long
It is 1.2~2.5 centimetres of seed, every square metre can put 400~450 in a suitable place to breed；The young cuttlefish of 3.0~5.5 centimetres long of trunk, often puts down
Fang meter Ke puts 300~35 in a suitable place to breed；Adding the composite microbe fertilizer of the invention can promote the fast-growth of cuttlefish, and EPA content increases
Plus, cuttlefishes disease is reduced, reduction of dying of illness, while also increasing the beneficial microbe in water body, final quality and quality are all
It is improved.
Cultural method in the invention and Sepiella maindroni cannot be suppressed in breeding process in the prior art
Precocity, lifts the reproductive capacity of Sepiella maindroni.
The content of the invention
The technical problems to be solved by the invention are to provide compacting Sepiella maindroni sex premature, the one of increase fish brood amount

Preferably, mode low after temperature is first high in step 5 is to reduce 1-2 DEG C with every 15 days temperature to be ultimately maintained at
22-24 DEG C, the mode that temperature is stepped up is that every 10-12 days temperature raise 1-2 DEG C.
Beneficial effect：The cultivation method for enhancing of this raising Sepiella maindroni reproductive capacity that the present invention is provided, can suppress
Sepiella maindroni sex premature, increases the head of Sepiella maindroni, and fish brood amount is changing pond fortune than generally much higher
The transportation resources of defeated middle use Nylon Bag oxygenation, it is ensured that the survival rate of Sepiella maindroni in transport, spore worm of being adulterated during nursing is net
Prevention diplostomiasis.
A kind of cultivation method for enhancing for improving Sepiella maindroni reproductive capacity is provided present invention employs above-mentioned technical proposal,
The deficiencies in the prior art are compensate for, it is reasonable in design, it is easy to operate.
Specific embodiment
It is described in further detail with reference to embodiments：
Embodiment 1
A kind of cultivation method for enhancing for improving Sepiella maindroni reproductive capacity, comprises the following steps：
1）Culturing area is set up：Set up multiple culturing areas and be respectively culture pond, seedling pond, culturing pool, culturing pool uses cement
Plate is built, and culturing pool depth is 3m, and the cultivation depth of water is 2m, and culturing pool periphery is provided with slope, and the gradient is 45 °, body temporary curing cement pond week
While be provided with some depths for 23m, a width of 10m circular groove as storage pond, holding pond, culturing pool top is provided with sunshade net, and culvert system is
Enter west in the east to go out, bottom of pond is plane, and gate mouthful is inclined in certain slope.
2）Pond treatment：With disinfectant, then pond pasteurised completely is reused with 75kg/ mus for example with limewash
Disinfectant, spiral shell essence of for example going out spills elimination cone reality spiral shell with 200g/ mu low to pond paving, is all spread around pond and pond after sterilization black
Color thickness mulch film, the low mud depth 20cm in pond is intake for 10 days before fry is put into.
3）Smart egg hatching：Placement is provided with egg apparatus in culture pond, embryonated egg water temperature be 20 DEG C, salinity be 26, water-soluble oxygen
Amount is hatched in the seawater more than or equal to 6mg/l, and water temperature is gradually risen in hatching process, is heated up with daily 0.4 DEG C, most
Constant temperature is cultivated after water temperature reaches 24 DEG C afterwards, controls the PH of seawater to be maintained at 7.5, and illumination is less than 500lux in hatching process, makes an uproar
Sound is less than 65 decibels, and seedling hatches the daily increase by 3 of increase and changes waterside number, and 4h starts with artemia without section children after seedling incubation of membrane
Body dispensing feeds for the first time as bait.
4）Seed rearing：The seedling that will be hatched is put in a suitable place to breed in seedling pond, and the seawater water temperature in seedling pond is 20 DEG C, and salinity is
30, illumination is 7000ux, and water-soluble oxygen amount is higher than 6mg/l, and pH value is 7.5, is fed with artemia nauplii dispensing, the component for feeding
Weight according to Sepiella maindroni gradually increases, and after seedling trunk 6mm ~ 8mm long, seed rearing is completed.
5）Seed is put in a suitable place to breed：The seedling that will be cultivated is dropped in culturing pool, input seedling trunk 8mm long, 100 every square metre,
Intake within 10 days before delivering seedling again, water inlet coolant-temperature gage is 30, and salinity 22, pH value is 7.5, and some algae are cultivated in culturing pool pond,
Aerator is provided with culturing pool, 22 DEG C was ultimately maintained in the form of 1 DEG C of drop using every 15 days using low after temperature first height during cultivation,
Based on chilled wild fishes feed, start progressively to heat up when ovary germinates was increased in the form of 1 DEG C using every 10 days, and was added
Plus the bait rich in unrighted acid PUFA is fed, start to feed rich in albumen and unsaturated lipid when ovary is further ripe
The fresh food of fat acid PUFA.
In the prior art of the routine techniques dawn known to those skilled in the art in step 1 ~ 5, narration is not in detail made herein.
Transportation resources of the pond using Nylon Bag oxygenation is changed in nursery, and the transportation resources of Nylon Bag oxygenation uses 40cm × 70cm
Nylon Bag can put 50 seeds, transported below 30 DEG C of temperature, avoid during transport high light direct projection, high temperature more than 33 DEG C with acutely rolling
It is dynamic, periodically sterilized with chlorine-containing agent full pool spilling head during water quality management, medicine is periodically added in bait is made bait feeding, described
Aerator in culturing pool is periodically opened, and fine day noon drives aerator 2 hours, overcast and rainy midnight start, is started shooting when raising the nose above water to breathe heavier
To daybreak, the fresh food composition and its weight portion rich in albumen and unrighted acid PUFA are：Compound protein powder 80
Part, 50 parts of unrighted acid, shrimp med 25, fish meal 25,3 parts of fish oil, 2 parts of vegetable oil, 3 parts of hemalbumin powder, 0.2 part of algin,
0.3 part of tamarind gum, 0.5 ~ 2 part of composite mineral matter, 1 part of plant acid, 1 part of carrotene, 3 parts of vitamin C, sodium alginate 0.5
Part, 0.3 part of thiamine.
Embodiment 2
According to the different cultural methods for implementing point ponds in stage, the composition changed in seawater by the different demands of different phase with
And different feeds are put into, first to using the smart cone reality spiral shell that pond is low of the spiral shell that goes out in pond with lime disinfection and then again before raising, in advance
There is diplostomiasis in anti-cuttlefish, after seedling trunk is long qualified, is cultivated with 30 DEG C of water temperatures at the beginning, then use temperature first after height it is low with
The form cultivation of 1 DEG C of drop in every 10 days, is ultimately maintained at 25 DEG C of constant temperature cultivation, so cultivates the low compressibility precocity of temperature, and
Head is big, and bait is based on chilled wild fishes；Start progressively to heat up when ovary germinates and increase within every 15 days 1 DEG C of form,
And addition feeds the bait rich in unrighted acid PUFA, reproductive capacity is improved, start to feed richness when ovary is further ripe
