Further improvement to said method: the bait feeding in the described mature stage management: after 3~May of spring and late October in autumn, satisfy the growth needs of sea cucumber, must manually throw something and feed, to remedy the bait deficiency, adopt marine alga processing algae powder more and be sprinkled into the ginseng pond after evenly with the ooze mixed diluting; Water quality exchange in the mature stage management: pond water day exchange capacity be greater than 30% of pond water inventory, when changing water, to be with net to enter with harmful organisms in the waterproof; Daily monitoring in the mature stage management: should note strengthening the monitoring of water quality, salinity, water temperature, sea cucumber growing state, security measure during the breed; Should note observing the activity of sea cucumber every day, and the situation of ingesting is regulated daily ration, feeding quantity, guarantees that sea cucumber keeps animation preferably, feels every 10~15 world water, observes the growing state of measuring sea cucumber; Harmful animal in the mature stage management is removed: thoroughly clean up the pond with bleaching powder before putting seedling, remove harmful animal, use at least 80 order net filtrations during water inlet, in case fish shrimp crab ovum and harmful animals such as the young, water flea thereof enter; Select 40~50 order net filtrations when intaking in the mature stage for use; Starfish will detect outside the pond and dry.
The present invention compared with prior art has the following advantages and good effect:
The present invention adopts discarded scallop cage as every mu cost-saved about 600 yuan of artificial sea cucumber rocks, and discarded scallop cage is turned waste into wealth, and reduces environmental pollution and waste.In actual mechanical process, the scallop cage is convenient to observe more, and operational administrative is very convenient, greatly reduces labour intensity.The results that also help the growth of the adhesion of ooze and benthon bait and sea cucumber are adopted and are caught.Material of the present invention is easy to get, and it is convenient, easy to utilize to implement.
Embodiment
The concrete grammar of preferred implementation of the present invention is:
(1) builds foster ginseng pond
Utilize local geography superiority at middle tide band or low tide band, cay substrate preferably, with the pond that concrete and stone are encircled a city shape, differed in size, the sea area enclosure wall that wind is big will be thickeied reinforcing; Or build the pond on the bank or utilize the transformation pond of shrimp-cultivation pool.To guarantee during neap that retaining is not less than 1.5 meters, and non-leakage; Must not there be pollution, especially oil pollution in selected sea area; Salinity is not less than 28%, and no river injects; Culture that the pond is respectively stayed one to advance, emptying gate, this pond seawater preferably relies on nature to receive tide, and the water yield of receiving every day is not less than 30%, and mean depth of water is more than 1.5 meters in the pond.
(2) throw in artificial sea cucumber rock
Some scallop cages are connected (quantity of connection is decided on pond length or width) one by one, stretch then, tighten, be fixed at the bottom of the pond, be vertical or horizontal laying, line space is a 3-5 rice.
(3) input of seedling
The input of seedling has two kinds of methods: the one, directly throw in method, and be suitable for the input of big specification seedling, the seedling of transporting back is spilt the waters that is put into the reefglider place uniformly; The 2nd, mesh bag is thrown in method, is suitable for the input of the small dimension seedling about the long 1cm of body.It is put into mesh bag, allow seedling slowly climb up artificial sea cucumber rock and adhere to, help improving survival rate.The input density of seedling can be according to the different and control rationally of the specification of seedling, by seedlings throw in less, the seedling principles of throwing in regulate more, the seeds of common 300~500/500 gram sizes are thrown in controllable density built in 10~30/square metre; Specification can be controlled in 5~10/square metre at the seedling of 30~50/500 grams.
(4) mature stage management
A, bait feeding:
In the pond, culture sea cucumber because density is bigger, the lacking of natural bait, especially after 3~May of spring and late October in autumn, because water temperature is lower, miniature animals and plants are less in the water, it is very clear that water seems, causes the bait wretched insufficiency, and at this moment be the thermophilic phase of sea cucumber growth, therefore, during this period, satisfy the growth needs of sea cucumber, must manually throw something and feed, to remedy the bait deficiency, adopt more some marine algas simply process or with manufactured feed be sprinkled into the ginseng pond.
B, water quality exchange
Change water except can guaranteeing water quality pure and fresh, can also provide the part natural bait, can also avoid the variation of pond water salinity in addition in rainy season, for sea cucumber provides metastable living environment for sea cucumber.Pond water day, exchange capacity was greater than 30 percent of pond water inventory, it should be noted that and will be with net to enter with harmful organisms in the waterproof when changing water.
C, daily monitoring
Should note strengthening the monitoring of water quality, salinity, water temperature, sea cucumber growing state, security measure during the breed.Be that Chi Shui changes maximum season summer, and too high as finding water temperature, water colour should change water unusually immediately, in order to avoid cause sea cucumber death; Should note observing the activity of sea cucumber every day, and the situation of ingesting guarantees that with take appropriate measures (adjusting daily ration, feeding quantity) sea cucumber keeps animation preferably, feels every 10~15 world water, measures sea cucumber, observes the sea cucumber growing state; Especially rainy season of the safety of pond dykes and dams, high sea more should note season.
D, removing harmful animal
Sea cucumber is easy to suffer attack and the predation of other aquatic animals because the self-defence poor ability, therefore removes the work of sea cucumber harmful animal and also be key one ring in culturing.The main harmful animal of sea cucumber has shrimp crab class, water flea, predacious fish, starfish etc.Available 20ppm bleaching powder is thoroughly cleaned up the pond before putting seedling, removes harmful animal, during water inlet with 80 order net filtrations, in case fish shrimp crab ovum and harmful animals such as the young, water flea thereof enter.Shrimp crab class can adopt the trapping of " cage " net between mature stage; Predacious fish can be with gluing net, and hook angles catches and kills, the most handy 40-50 order net filtration when intaking in the mature stage; Starfish will detect outside the pond and dry.
Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention is not limited to above-mentioned giving an example, those skilled in the art, and in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement all should belong to protection scope of the present invention.
