Description
Technical field
The utility model belongs to coral cultivation field, is specifically related to a kind of device cultivated and collect coral fertilized egg.
Background technology
Coral phylum cnidaria is the underlying biological of composition coral reef ecologic system.Coral reef system healthy in ocean, the whole world every year every square kilometre of fishery production reaches 35t, the fishery production in the whole world about 10% comes from coral reef area, with oneself, 1/4 of all marine species know that 1/5 (4500 kinds) of marine fishes are all lived in coral reef ecologic system.The stable Quantityanddiversity for maintenance marine species of coral reef ecologic system is extremely important.
But in recent years, under the impact of the mankind and the dual-pressure of global warming, occurred in the world the phenomenon that many places coral reef is degenerated being mainly manifested in reducing gradually and disappearing of coral reef.Because the marine organisms lived in coral reef ecologic system lose the habitat of depending on for existence, their Quantityanddiversity also correspondingly significantly reduces.This has also had a strong impact on the quantity of the catch of fishery and the income of fisherman.In order to slow down the rate of decay of coral quantity, increasing coral quantity, maintaining diversity of organism in coral reef, generally attempt at present manually cultivating coral.
Anthozoic mode of reproduction has two kinds: sexual reproduction and asexual reproduction.Coral polyp divides hermaphroditism and gonochorism two type; Anthozoic asexual reproduction refers to: the ejaculation ovulation respectively of the spermary on hermaphroditic coral polypide inner septum and ovary, and sperm and ovum combine and form fertilized egg, and grow in gastrovascular cavity; Anthozoic sexual reproduction refers to: ejaculation, the ovulation respectively of dioecious anthozoic male body and female body, sperm enters female body with current and is combined with ovum, and grows in gastrovascular cavity.No matter be sexual reproduction or asexual reproduction, fertilized egg all will be discharged by stomatodeum, then develop into larva in vitro when growing in anthozoic gastrovascular cavity and arrive similar maturation.
The artificial culture process of coral comprises carries out concentrating cultivation to a large amount of coral fertilized eggs.At present, the coral fertilized egg used in this process obtains mainly through field acquisition.But field acquisition not only needs to be artificially collected by diver, labor intensive and material resources, and owing to being difficult to predict the time of coral discharge fertilized egg under natural conditions, cause collection efficiency low; In addition, easily fertilized egg is damaged in the process of artificially collecting, cause lower being proliferated into motility rate.
Utility model content
The utility model object is to provide a kind of device cultivated and collect coral fertilized egg, and it drastically increases the collection efficiency of fertilized egg, saves man power and material, and adds the artificial fecundation survival rate of coral fertilized egg.
Solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
Cultivate and collect a device for coral fertilized egg, it is characterized in that comprising:
A transparent coral hatches water tank, its inside is provided with one or more parent and breeds case, each described parent is bred case and is provided with an outlet pipe, described outlet pipe respectively leads to a fertilized egg collecting box, and has the fertilized egg collector one dismountable, bottom surface is filter screen at the exit of described outlet pipe cover;
Described coral is hatched above water tank and is also provided with a water inlet manifold, and described water inlet manifold is communicated with one or more and leads to the water inlet pipe that each parent breeds case;
Described outlet pipe, drainpipe are all provided with check valve, and to control the direction of current, stationary flow speed, prevents from flowing backwards.
Preferably, described coral is hatched in water tank and is also provided with overflow pipe, and its upper limb height hatches the top edge height of water tank lower than coral, and inside is provided with check valve.When the seawater that coral is hatched in water tank is too much, drain by overflow pipe.
Preferably, the back wall that described coral hatches water tank is also provided with one or more drainpipe.When hatching water tank to coral and cleaning, unnecessary sewage can be disposed to outside water tank by drainpipe.
Preferably, the water outlet of described water inlet pipe is also provided with filter.This filter is used for the impurity in filtering sea, such as algae or plankton etc.
The utility model by building the flowing of water body, and controls speed and the temperature of current, for desirable environment is built in the ovulation of coral parent propagation, improves the efficiency of coral parent ovulation.Simultaneously, the flowing of the fertilized egg that current drive coral parent to discharge, and be automatically collected at fertilized egg collector place, thus avoid the existing damage artificially collected fertilized egg, improve the collection efficiency of coral fertilized egg under indoors artificial proliferation conditions and survival rate.
Particularly, the water inlet pipe that first seawater passes through water inlet manifold and be communicated with water inlet manifold, injects coral parent and breeds case.Subsequently, then flow through outlet pipe, to fertilized egg collecting box, finally hatch in water tank at coral and collect.Unnecessary seawater can be discharged by overflow pipe.After the coral parent coral parent of breeding in case discharges fertilized egg, fertilized egg Parallel to the flow direction flows, and the fertilized egg collector being arranged on outlet pipe exit retains collection.
The seawater part of overflowing fertilized egg collecting box is retained in coral and hatches in water tank, for breeding of coral parent provides water bath heat preservation.
Coral of the present utility model is hatched water tank and is used transparent material to make, and light-permeable, is conducive to the breeding of coral parent, is also conducive to staff and observes coral parent ovulation state.
Compared with prior art, the utility model has following beneficial effect:
1., by water-in and water-out speed and water temperature in adjustment water tank, the condition of simulation coral parent required for natural environment propagation, improves the output of fertilized egg;
2. retained by screen pack and automatically collect fertilized egg, reduce manual labor, and avoid the destruction artificially collected fertilized egg, greatly improve collection efficiency and fertilized egg survival rate;
3. hatch with spilling seawater temperature control, the propagation not being only coral parent provides stable condition, more improves propagation water body availability, decreases total water consumption;
4. utilize the natural sea-water of flowing as propagation water body, simulate the condition that coral parent is bred under natural environment to greatest extent, and ensure that the food source of parent coral.
