Abstract
The invention discloses a method for artificially culturing perineries aibuhitensis in a biological filter. The method is mainly characterized in that: a gravel layer, a coarse sand layer, a fine sand layer and a soil layer are sequentially spread from bottom to top in the filter provided with a water inlet pipe and a drain pipe. Before clamworm seedlings are put into the filter, fresh water is injected into the whole filter, the filter is soaked for 1 week, the fresh water is drained after 1 week, and fresh seawater is injected. The perineries aibuhitensis seedlings are artificially scattered, the size of the seedlings is 3 to 10 joints, and the seedling density is 600 to 2,000 pieces per square meter. The quantity of bait is 8 to 12 percent of the overall weight of the perineries aibuhitensis in the filter, and the bait consists of residual bait and feces of artificially cultured seawater fish, wherein the residual bait and feces are filtered and collected by a silk net of 50 to 100 meshes and concentrated and dried. The temperature of the perineries aibuhitensis culture water in the filter is 4 to 40 DEG C; in 1 to 2 weeks after the seedlings are put, water is not drained, and only water is injected; and after 1 to 2 weeks of putting the seedlings, the water is changed twice every day, and the water in a volume which is 1/3 of the volume of the filter water is artificially changed every time. By the method, the perineries aibuhitensis with high survival rate can be cultured artificially in batch.
Description
Technical field
the present invention relates to the method that a kind of aquaculture method, particularly artificial culture enclose clam worm.
Background technology
Enclose clam worm and belong to Annelida; Enclose Nereidae; It is a kind of typical intertidal zone zoobenthos; Be the high-quality bait of important aquaculture organisms (fish, shrimp) simultaneously; Also be the important step of marine ecosystems energy Flow and material circulation, it is playing the part of the key effect of forming a connecting link in marine ecosystems.Research shows, encloses clam worm and belongs to medium-and-large-sized Polychaeta animal more, and the particle size range of its nature sedimentary particle of ingesting is (10～250 μ m) very extensively, to sedimental grazing rate average out to 5.71+2.76mg.mg-1dw.d-1 (Wang Shihong, Zhang Zhi south, 1998); Handle the sediment yield (Loper G L, Leventon J S., 1987) that is equivalent to body weight (dry weight) at least its every day through feeding activity.Utilize and large-scalely enclose the clam worm animal ingesting of organic granular material repaired and handled industrialized aquiculture system with transformation function, have using value.
Yet, to disperse to be grown in the natural environment owing to enclose clam worm, Protean external environment not only can not satisfy the growth needs of clam worm, make its survival rate low, and the dirt-removing power of clam worm can not given full play to.
Summary of the invention
The object of the present invention is to provide a kind of can cultivate in batches and biofilter that survival rate is high in the artificial culture method of enclosing clam worm.The present invention cultures to enclose the Nereidae animal in artificial constructed biofilter, and various enclosing under the clam worm suitable growth condition that manual work is created in the filter tank lived.
Technical solution of the present invention is following:
1, biofilter: there is a upper shed groove in this filter tank, and this groove can adopt various materials to process, like the inside and outside metal material of all establishing anticorrosive coat, nonmetallic materials, the filter tank of preferably adopting brick and cement masonry.5-10 ° of the preferably preceding high back of this filter tank bottom land low dip is to make things convenient for the water in the emptying pond.Establish water inlet pipe at this top, filter tank, in the bottom, pond, preferably low level one side is provided with drainpipe at the bottom of the pond; Drainpipe passes back, pool wall bottom and links to each other with the filter tank outer water pipe with elbow; Mouth of pipe height through adjustment pool outer water pipe changes water level in the filter tank, forms miniflow water nereis culture mode.Lay gravel layer, coarse sands layer, fine sand layer and dirt bed in the filter tank from bottom to top successively, wherein gravel size is 1～3 * 1～2 cm, and thickness is 8-12cm; Fine sand particle diameter 0.5-1.0mm, thickness are 13-17cm; The dirt bed lower thickness limit is 10cm.
2, enclose the input pre-treatment of clam worm seedling: before the clam worm seedling is thrown in, inject fresh water in the whole filter tank, soaked for 1 week.After 1 week, discharge fresh water, inject fresh seawater.
3, enclose clam worm and throw seedling: enclose the mode that the Nereidae seed all adopts manual work to splash, water is ladled out band water and is evenly splashed in the filter tank, and the seed size has just saved for 3-10, throwing seedling density be the 600-2000 tail/square metre.Saidly enclose that the Nereidae animal comprises perinereis aibihitensis Grube, multiple toothly encloses clam worm, solely tooth encloses clam worm and flat tooth encloses clam worm, pillow encloses clam worm and Japan thorn clam worm.
4, clam worm is thrown something and fed: bait throwing in quantity is to enclose the 8-12% of clam worm TBW in the filter tank, along with the growth of clam worm progressively increases bait.Residual bait of the marine fish of propagating artificially and the ight soil that dries is collected and concentrated to bait for filtering through 50-100 mesh sieve tulle.The marine fish of propagating artificially comprises turbot, lefteye flounder, Cynoglossus semilaevis, salmon and grouper etc.
5, cultivate water temperature and change the water mode: the kind according to enclosing clam worm is different, and clam worm cultivation water temperature excursion is 4-40 ℃ in the filter tank.1-2 adopts not draining in week after throwing seedling, and the mode of a water filling is cultured after putting seedling.Throw seedling 1-2 after week, can adopt and change water twice every day, the mode of each 1/3 filter tank water volume is carried out artificial changing water.
6, dead clam worm is handled: find to occur getting out above the dirt bed of filter tank, motionless dead clam worm is in time used the dead clam worm of mode sucking-off of plastics pipe racks water siphon, the communicate illness in order to avoid dead clam worm is rotted.
7, clam worm growth measurement: regularly got unit are (10cm in every month
2), take all clam worms in this area, count and weigh unit of account clam worm average weight.Through the monthly variation of average weight, record clam worm growing state, and in time adjust the quantity of throwing something and feeding.
The present invention compared with prior art has following advantage:
1, clam worm begins just to put into artificial filter tank from seed, and progressively in good filter tank artificial environment, grows up, and is not subjected to external environmental interference; Simultaneously its to the adaptation of filter tank environment from little beginning, strong to the adaptive capacity of filter tank environment.
2, enclose clam worm and begin from the young, its bait is the ight soil and the residual bait of marine fish culture, and it has adapted to this kind bait for a long time, has guaranteed after clam worm grows up the food of having a liking for to this kind bait, so that bring into play ingesting and transformation efficiency of clam worm in the filter tank better.
3, enclose clam worm survival rate height.Because the existence of above-mentioned two advantages, the clam worm survival rate and provides sufficient organic matter under the prerequisite of bait in manual work up to more than 90% in the filter tank in, and the clam worm growth rate is fast.
