Description
Technical field
The utility model relates to a kind of cultivating pool sediment trap, belongs to fishery ECOLOGICAL ENVIRONMENTAL MONITORING technical field.
Background technology
Since the reform and opening-up, the fishery development policy of " to support " is carried out by China.2006, China's freshwater aquiculture output reached 2148.31 ten thousand tons, accounted for 59.78% of aquaculture total production (3593.95 ten thousand tons); Wherein, freshwater cultured output and area are respectively 1494.51 ten thousand tons and 2531.05 thousand hectares, account for 69.57% and 42.06% of freshwater aquiculture output and area respectively, and freshwater is cultured the contribution of freshwater aquiculture very important.Pond culture becomes the main body of China's aquaculture with its area, the output critical role in total amount.Yet in the behind that pond culture already develops rapidly, the pollution problem that itself exposes is troubling.Existing pond culture pattern is many from devoting exclusive attention to output and economic benefit, exchanges high production for high flow rate, the high investment of feed, fertilizer, medicine etc., causes pond waters seriously polluted, the deterioration of the ecological environment.There are some researches show in the moist forage that pond culture is thrown something and fed, have 5-10% not eaten by fish; And had 25-30% to discharge in the feed of the edible digestion of fish with the form of ight soil; The nitrogen of nature and artificial input, phosphorus have at least 50% enrichment to become the pond sediment except that only a part of with the breed variety output.Sediment is meant physics, chemistry that takes place and the precipitum that biological process produced in the water body scope.In cultivating pool, do not form the pond sediment at the bottom of the residual bait of being ingested by fish, fish excreta, aging dead plant and animal residues and dust silt etc. are deposited on the pond.The pond sediment directly contacts with water body, influences water quality from many aspects, is the nutritive salt storehouse of pond waters, is being disturbed or during changes in environmental conditions, will producing material impact to the breeding water body environment; Simultaneously, when the desilting of pond, the pond sediment can pollute external environment.Therefore, research pond sedimental generation is all significant to the pollution level of self and pond external environment etc. for science regulation and control pond water quality and assessment pond culture.
Summary of the invention
The purpose of this utility model is the pond culture pattern that is to make a kind of comparatively science, easy row, can detect the sediment generation in fish culture pond accurately, and the estimation pond culture is to a kind of cultivating pool sediment trap of the pollutional load of self.
The technical scheme that provides according to the utility model, a kind of cultivating pool sediment trap comprises foam plastic float, rope and gatherer body, the side-walls of described gatherer body upper bottom surface is provided with hole uniformly, and rope one end is connected with hole, and the other end connects foam plastic float.
The stage body shape that described gatherer body is a hollow, stage body is shaped as round platform or terrace with edge, and gatherer body upper base area can be arranged on 0.03-0.15m
2
Described gatherer body bottom surface internal diameter is 24cm, and the bottom surface internal diameter is 46cm, high 20cm.
Described gatherer bulk material can adopt glass, organic glass or stainless steel material to make.
The utlity model has following advantage: the utility model collection method science, easy row; Can detect the sediment generation in fish culture pond accurately, the estimation pond culture is to the pollutional load of self; It is all significant to the pollution level of self and pond external environment etc. for science regulation and control pond water quality and assessment pond culture to detect the sedimental generation in research pond.
Description of drawings
Fig. 1 is the structural representation of the utility model gatherer.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1: comprise foam plastic float 1, rope 2, hole 3, gatherer body 4.
The utility model sediment trap is designed to the truncated cone-shaped glass container of hollow, and vessel port is in the upper bottom surface of stage body, and the sediment that can prevent from like this to sink in the gatherer scatters and disappears to water body because of the influence of factors such as current stirring.Container upper bottom surface internal diameter is 24cm, and the bottom surface internal diameter is 46cm, high 20cm.3 holes 3 being set uniformly near the side-walls of gatherer body 4 upper bottom surfaces, be used for tether 2, the rope top is a foam plastic float 1, thus the indication gatherer in the pond approximate location and be convenient to sediment trap is picked up.In stocked carp sediment trap is put at the bottom of the pond, results are taken out sediment trap fish the time, and then the sediment in the gatherer is the sediment generation under this area (above floorage meter) during the breed.Can calculate the sediment generation of unit area in view of the above, and and then calculate the sediment generation in whole pond according to the pond planimeter.
General adopt " five-spot " placed sediment trap in cultivating pool, promptly respectively place a sediment trap in central authorities and four corners in pond.In stocked carp sediment trap is put at the bottom of the pond, results pick up sediment trap fish the time, and then the sediment in the gatherer is the sediment generation under this area (above floorage meter) during the breed.Can calculate the sediment generation of unit area in view of the above, and and then calculate the sediment generation in whole pond according to the pond planimeter.
The aquaculture organism on the table 1 test pool is put in a suitable place to breed and the results situation
Tilapia mossambica (Oreochromis niloticus) the parent fish rearing pool of test base is adopted on the test pool.Sediment is collected test and is carried out in two mouthfuls of ponds, is labeled as pool I and pool II respectively, and the area in each pond is 0.067hm
2(29m * 23m), depth of water 2m.Placing a sediment trap respectively in the center in pond (1# point) and three corners (2#, 3#, 4# point) (has one to be water inlet in four turnings in pond, so only place gatherer at other three turnings), put into 4 sediment traps in each pond altogether.Gatherer places and the time that picks up puts in a suitable place to breed with Tilapia mossambica respectively and harvest time is consistent, promptly is respectively May 2 and November 2, totally 185 days.Duration of test, the bait feeding amount in two ponds, source water source and disposal route and other daily aquaculture management measures are in full accord.The bait feeding amount of duration of test increases with the increase of Tilapia mossambica body weight, average out to 5kgd
-1(d represents the sky).Except that a small amount of moisturizing being carried out in the pond because of evaporation, seepage so that pond waters remained unchanged, duration of test did not change water, does not use oxygen increasing equipment.Each Tilapia mossambica of testing the pool is put time, stocking rate, stocking size and harvest time, harvest yield in a suitable place to breed, the results specification is as shown in table 1.
The measuring and calculating of pond sediment quality: sediment trap is picked up and takes back the laboratory, staticly settle 24h after, upper water is discharged by siphonage.Be placed on room ventilation place cold to upper strata afterwards and do not have obvious water layer.
With the sediment quality in the difference assay measuring and calculating sediment trap, promptly first weighing gatherer and sedimental gross mass (W
Always), the quality (W of weighing gatherer again
Receive), sedimental quality (W in the gatherer then
Sediment) be W
Always-W
ReceiveThe sediment yield that each gatherer that application the utility model method calculates is collected is as shown in table 2.
The sediment yield that each gatherer on the table 2 Tilapia mossambica parent culture pool is collected
