Abstract
The invention provides an artificial egg taking method for sepia pharaonis. An egg taking place is subjected to water exchange by using a slow water flowing method, the water exchange amount is over 3 full doses, one side of the egg taking place is continuously subjected to air inflation, and an egg taking device is placed on the other side of the egg taking place; and an environment applicable to the egg taking place and an appropriate transportation way are selected. Through the invention, collected eggs are more in number and high in survival rate, the collecting cost is low, and the collecting method is simple.
Description
Technical field
The present invention relates to a kind of artificial acquisition technique, be specifically related to a kind of method of tiger spot cuttlefish ovum artificial collection.
Background technology
It is a new industry of China that cuttlefish is propagated artificially, and the report of golden cuttlefish and the success of Sepiella maindroni factorial seedling growth is arranged at present, includes these two kinds of cuttlefish mating, lays eggs, the patent application of the artificial breeding technique such as hatching and larval culture.The tiger spot cuttlefish is tropical deep large kind, with these two kinds be the marine site, temperate zone kind living environment and lay eggs and notable difference arranged in the behavior.Such as, the behavior of dwelling at the bottom of the tiger spot cuttlefish is obvious, and swimming time is significantly shorter than the time of having a rest, likes in half-light, quietly mating under the condition, likes laying eggs at the dark colour adherance etc.So the method for tiger spot cuttlefish ovum artificial collection also has its special character.
Just require the spawning pond depth of water more than 2 meters, spread 5-10 centimetre of fine sand (0.5～1.25 millimeter of diameter) indoor light at the bottom of the pond less than 200lux, lay a side of adopting egg apparatus in the pond and do not inflate.The seawater salinity of tiger spot cuttlefish and golden cuttlefish life is also different, and the tiger spot cuttlefish can live in 28-35 ‰ seawater.
Summary of the invention
The method that the purpose of this invention is to provide a kind of tiger spot cuttlefish ovum artificial collection.
The technical scheme of taking for the present invention that achieves the above object is:
A kind of method of tiger spot cuttlefish ovum artificial collection comprises the steps:
(1), migration is supported and is transported to the ground of laying eggs temporarily to putting into dredger running water storehouse after the tiger spot cuttlefish adult of offshore is caught;
(2), the net cage of selecting on the bank cement pit, large-scale PVC bucket or bank is as laying eggs ground, area is more than 10 square metres, the depth of water is more than 2 meters, the 5-10 centimetre of fine sand in shop, the end, ground of laying eggs, the diameter of fine sand is 0.5～1.25 millimeter;
(3), adopt the way of miniflow water to carry out the water exchange, water exchange capacity is at 3 more than the full dose with laying eggs, lay eggs ground one side continuous charge another be sidelong and adopt egg apparatus;
(4), adopt coir rope net sheet, nylon mesh sheet or the PVC plastic crate that egg apparatus adopts dark colour (as black, red, brown);
(5), lay eggs ground environment: seawater dissolved oxygen 7.5 mg/litre, ammonia-nitrogen content＜0.1 mg/litre, nitrite＜0.05 mg/litre, salinity is 28-35 ‰, water temperature 20-28 ℃, illumination is less than 200lux, and room noise is less than 65 decibels, breeding density 3-4/square metre, net cage can reach 7-8/square metre, the preoviposition period, female and male ratio is 3: 1, spawning period, female and male ratio are 2: 1; The fresh and alive shrimp crab class of mainly throwing something and feeding is take small fish as auxiliary material;
(6), when egg laying amount is little, collected once in per 2 days; Spawning period one day is collected and is adopted egg apparatus once, and ovum is focused in the hatchery hatching or is transported to other nursery.
Adopting egg apparatus soaks with 3/1000ths to 5/1000ths liquor potassic permanganate and can be reentered into attached ovum in the spawning pond after 10 minutes.The long-distance transport of ovum can be selected aviation, highway and railway, and haulage time is the longest to be 48 hours; The short-distance transport of ovum can be selected running water car, in transit continuous charge; In order to prevent that the ovum grain is squeezed in transit, first the ovum string is put into plastic crate or brandreth basket.
The method of miniflow water namely refers to: 2-4 water inlet pipe installed at the diagonal place at spawning pond (preferably circular pond), makes water make horizontal tangent along pool wall and flows.Spread one deck fine sand at the bottom of the pond, have a rest to satisfy the end dwelling property cuttlefish.Osculum is placed in pond central authorities lowest part, with outlet pipe (PVC or other material) water is drawn spawning pond.By regulating inflow, the height of drainpipe, the water yield of drainpipe, make depth of water keep about 2 meters, water day, exchange capacity was at 3 more than the full dose.
By the present invention, the ovum quantity of collection is many, survival rate is high, and acquisition cost is low, collecting method is simple.
Embodiment
Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
Embodiment 1:
A kind of method of tiger spot cuttlefish ovum artificial collection comprises the steps:
(1), migration is supported and is transported to the ground of laying eggs temporarily to putting into dredger running water storehouse after the tiger spot cuttlefish adult of offshore is caught;
(2), select the large-scale PVC bucket as laying eggs ground, area is more than 50 square metres, 3 meters of the depth of waters, 5 centimetres of fine sands in shop at the bottom of the large-scale PVC bucket, the diameter of fine sand is 0.5 millimeter;
(3), the large-scale PVC bucket adopts the way of miniflow water to carry out the water exchange, water exchange capacity is at 3 more than the full dose, lay eggs ground one side continuous charge another be sidelong and adopt egg apparatus;
(4), adopt the PVC plastic crate that egg apparatus adopts black;
(5), lay eggs ground environment: seawater dissolved oxygen 7.5 mg/litre, ammonia-nitrogen content 0.05 mg/litre, nitrite 0.01 mg/litre, salinity are 30 ‰, 23 ℃ of water temperatures, illumination is less than 150lux, and room noise is less than 50 decibels, 3/square metre of breeding density, the preoviposition period, female and male ratio is 3: 1, and spawning period, female and male ratio are 2: 1; The fresh and alive shrimp crab class of mainly throwing something and feeding is take small fish as auxiliary material;
(6), when egg laying amount is little, collected once in per 2 days; Spawning period one day is collected and is adopted egg apparatus once, and ovum is focused in the hatchery hatching or is transported to other nursery.
Adopting egg apparatus soaks with 3/1000ths to 5/1000ths liquor potassic permanganate and can be reentered into attached ovum in the brood pond after 10 minutes.The long-distance transport of ovum can be selected aviation, highway and railway, and haulage time is the longest to be 48 hours; The short-distance transport of ovum can be selected running water car, in transit continuous charge; In order to prevent that the ovum grain is squeezed in transit, first the ovum string is put into plastic crate or brandreth basket.
By the present invention, the ovum quantity of collection is many, survival rate is high, and acquisition cost is low, collecting method is simple.
