Embodiment 1: the foundation of cultivating condition
1. the condition of aquaculture pond
Deep 1.2~the 1.8m in pond, area be 0.5~2 mu preferably.If water temperature is more than 33 DEG C during putting in a suitable place to breed, need to be at the top of greenhouse
Paving draws sunshade net, avoids high temperature and Qiang Guang, and ambient enviroment is kept quite as far as possible.
2. putting previous work in a suitable place to breed
(30 days) progress aquaculture ponds are leveled and are sterilized before tiger spot cuttlefish is put in a suitable place to breed, are generally discharged water to 30~40cm, clear pond
Quick lime can be used, usage amount is generally 100~150Kg/ mus per acre, also can be used bleaching powder, usage amount is 40 per acre~
50Kg/ mus.On the one hand to kill harmful organisms, bottom of pond sapropel is removed on the other hand to improve water quality and substrate.It cleans up the pond after processing,
It puts in a suitable place to breed and carries out within first 15~20 days water storage work, (inoculation oppossum shrimp or common shrimp seedling, put 10 in a suitable place to breed to culture foundation bait per acre in pond
Reserve living bait of~15 ten thousand common shrimp seedlings of tail as cuttlefish), water depth 1.2m~2m, while Feeding time selection is daily early
Upper 6:00~6:30 (once a day).Bait litopenaeus vannamei compound feed is fed, litopenaeus vannamei compound feed feeding volume is opened
Begin to be 2.5~3.5Kg/ mus, increases by 0.25~0.325kg/ mus (maximum daily ration, feeding quantity 7.5Kg/ mus) daily.
3. seed is put in a suitable place to breed
Selection health, vigor are good, the tiger spot squid larva of a length of 3cm of trunk.It is the preferred cloudy day, somewhat drizzly when seed is put in a suitable place to breed
It is best when rain but not low air pressure, if weather is all that comparison is hot, that will ensure to put seedling before the sun comes out.Greatly
Water temperature is no more than 32 DEG C (putting the seedling time as mid-June~mid-July) in canopy, it is therefore desirable to cover sunshade net on aquaculture pond top.
When putting seedling, it should be noted that water and transport are used the temperature of water body, the quality of salinity difference and cuttlefish seed in Nylon Bag and put in a suitable place to breed
Density.It can be floated on Nylon Bag in water and the method for addition water gradually transition eliminates the difference of temperature and salinity.Seed is put
When supporting, the plastic film bag equipped with seed is first allowed to float 10~15min in aquaculture pond, then seed is poured out.Cultivation density: tiger
Spot cuttlefish trunk grows 3~5cm, and cultivation density is 20~25/m2;As trunk long 5.0~7.0cm, 15~20/m of cultivation density 2.
4. aquaculture management
4.1 water quality management
Should be grasped in breeding process, when changing water slow-motion slowly go out principle, avoid hydro-environmental change excessive and make cuttlefish by
, there is ink-jet phenomenon in scaring.Water temperature control is at 23~33 DEG C, and 24~30, (water is based on keeping stablizing for salinity control;In case of
Special circumstances cannot change water, can not bait throwing in material, to reduce the influence that water quality is ruined), water transparence control 30cm~40cm,
For water colour clearly to faint yellow, appropriate pH 7.9~8.2, dissolved oxygen is not less than 5mg/L, and ammonia-nitrogen content is not higher than 0.1mg/L.Depth of water control
In 1.2~1.8m, (megathermal period water level will keep highest to system, and as far as possible should change the refrigerant fresh seawater in off-lying sea more, make water temperature
It is maintained within 33 DEG C).Dissolved oxygen control is in 5mg/L or more, and pH value control is 8.0~8.2, ammonia nitrogen < 1mg/L.Before changing water, one
Surely first to survey the temperature and salinity (such as temperature is no more than 4 degree and salinity range only 5) of sedimentation basin and reservoir, quantity of exchanged water according to
Cuttlefish food ration, the conditions such as water quality situation into, it should be noted that can not excessively change water, so as not to cause stress, generally once change water 20~
50%.If changed within every 5 days water 1 time, quantity of exchanged water 20% (or every 15 days primary, change water 30~50%).Measurement water temperature, salt daily
Degree, pH value, ammonia nitrogen and the relevant water quality indicator of cultured water simultaneously make a record.Due to the closure of warm canopy environment, make in water body
Cannot discharge, in water, the injury of the gill and liver of prawn is very big for accumulation.Green Verbatim or pond can be used per each (10~15 days)
The antidotes such as pool pellet for detoxication detoxify to pond.
4.2 feedstuff feeding
A bait table is respectively designed on four side of pond, feeds and feeds process when process just starts slowly, on a small quantity, by 5~8 days
Cuttlefish adaptation aquaculture pond is ingested afterwards, can normally be fed.Feeding time selection in every morning 6:30, afternoon 4:00 and at night 8:
30 (the first 15 minutes lamps for opening bait throwing in point being fed at night, because tiger spot cuttlefish has phototaxis), the process of feeding need to accomplish timing, determine
Point.Feed food species, size and daily ration, feeding quantity: when tiger spot cuttlefish trunk 3.0~7.0cm of length, bait is long 1.5~2.5cm, width
The frost small fish of 0.3~0.8cm or shrimp, daily bait feeding weight are the 13~17% of its weight;Tiger spot cuttlefish trunk is long
When 7.0~11.0cm, bait is that long 2.5~4.0cm, wide 0.5~1.5cm freeze small fish or shrimp, daily bait feeding weight
It is the 10~14% of its weight;When the long 11.0~15.0cm of tiger spot cuttlefish trunk, bait be long 3.0~4.0cm, it is wide by 1.0~
2.0cm freezes small fish, shrimp, and daily bait feeding weight is the 10~12% of its weight;The long 15cm or more of tiger spot cuttlefish trunk,
Bait is whole frost small fish, shrimp, and daily bait feeding amount is the 8~10% of its weight.Daily regular check feed table,
Removed in time if having residual bait, day feeding volume mainly according to the ingesting of cuttlefish, grow, cut one another's throats, in water situations such as live bait, together
When combine the conditions such as weather, water quality to comprehensively consider.If individual differs greatly it was found that the growth of cuttlefish is irregular, just illustrate bait
Material biology feeds deficiency, Ying Jia great feeding volume.
4.4 fish and transportation resources
Cultivation pool water level is drained into 15~25cm, is captured with diddle-net directly or with purse seine, process needs gently,
Reduce the interference to cuttlefish.Transportation resources: using Nylon Bag oxygenation transport, Nylon Bag specification is 50 × 25 × 25cm, fills water 1/
4, per packed cuttlefish 1~2 (250 grams of weight 2, each bags, 500 grams of weight 1, each bags).
A kind of specific cultivating condition is as follows:
Pond depth 1.5m, area are 1 mu, and paving draws sunshade net at the top of greenhouse.It puts in a suitable place to breed early period, tiger spot cuttlefish puts the previous moon in a suitable place to breed
Before, aquaculture pond is carried out disinfection using 100~150Kg/ mus of quick lime, rear to clean.Culture foundation bait connects low 5 days after disinfection
The common shrimp seedling (the long 1.5cm of body) of kind, puts reserve living bait of the common shrimp seedling of 150,000 tails as cuttlefish in a suitable place to breed, simultaneously per acre in pond
Feeding time is selected in 6:30 every morning (once a day).Bait litopenaeus vannamei compound feed is fed, Penaeus Vannmei is matched
It closes feedstuff feeding amount to start to be 2.5~3.5Kg/ mus, increases by 0.25~0.325kg/ mus (maximum daily ration, feeding quantity 7.5Kg/ mus) daily.
When tiger spot cuttlefish seed is put in a suitable place to breed, it is ensured that salinity and aquaculture pond during seed breeding are nearly.Selection is launched at the cloudy day, first allows dress
There is the plastic film bag of seed to float 15 in aquaculture pond
Min, then seed is poured out.Cultivation density: the long 3cm of tiger spot cuttlefish trunk, cultivation density are 25/m2.Breeding process
Water quality management: the principle that slow-motion goes out slowly should be grasped when changing water in breeding process, water temperature control is at 26~32 DEG C during cultivation, salt
24~30, water transparence controls 30cm~40cm, appropriate pH 7.9~8.1, dissolved oxygen 5mg/L or more, ammonia nitrogen for degree control
Content is not higher than 0.1mg/L, and the depth of water is controlled 1.2~1.5m (when about 30 DEG C of water temperature, water level is maintained at 1.5m depth).It changes
Before water, the temperature and salinity (guarantee that temperature is no more than 4 degree and salinity range only 5) of sedimentation basin and reservoir are first surveyed, every 5 days
It changes water 1 time, quantity of exchanged water 20% (when every 15 days one time, quantity of exchanged water 40%).Daily measurement water Inversion phenomenon, pH value, ammonia nitrogen and
The relevant water quality indicator of cultured water simultaneously makes a record.Per each 15 days using the antidotes such as green Verbatim or pond pellet for detoxication to pond
Detoxify primary.Feedstuff feeding: respectively designing a bait table on four side of pond, feed fed when process just starts process it is slow,
On a small quantity, cuttlefish adaptation aquaculture pond is ingested after 5 days, can normally be fed.Feeding time selected in every morning 6:30, afternoon
4:00 and evening 8:30 (feeding the first 15 minutes lamps for opening bait throwing in point at night).Feed food species, size and daily ration, feeding quantity: tiger spot
When cuttlefish trunk grows 3.0~7.0cm, bait is to grow 1.5~2.5cm, the frost small fish of wide 0.3~0.8cm or shrimp, daily bait
Feed 13~17% that weight is its weight;When tiger spot cuttlefish trunk 7.0~11.0cm of length, bait is long 2.5~4.0cm, width
0.5~1.5cm freezes small fish or shrimp, and daily bait feeding weight is the 10~14% of its weight;Tiger spot cuttlefish trunk is long
When 11.0~15.0cm, bait is that long 3.0~4.0cm, wide 1.0~2.0cm freeze small fish, shrimp, daily bait feeding weight
It is the 10~12% of its weight;The long 15cm or more of tiger spot cuttlefish trunk, bait are whole frost small fish, shrimp, and daily bait is thrown
The amount of feeding is the 8~10% of its weight.Daily regular check feed table, has residual bait then to remove in time, when the growth of discovery cuttlefish
Irregular, individual differs greatly, and just illustrates that food organisms feed deficiency, increases feeding volume.By cultivation in about 130 days,
Tiger spot cuttlefish reaches the commercial specification (average weight 0.463kg) of listing, cultivation survival rate 64.6%.And outside existing aquaculture model
Room soil is pool cultivated, and by about 130 days pool cultivated tiger spot cuttlefish survival rates 21.5% of mistress's soil, weight average weight was
0.267kg.Tiger spot cuttlefish greenhouse aquaculture model its cultivation survival rate of mode more pool cultivated than mistress's soil improves 200.5%,
Weight improves 73.4%.
