Abstract
The invention discloses a spat culture method for intertidal zone shellfish seeds, which comprises the following steps of: selecting a pool with more sand and less mud as a fingerling-holding pond, thoroughly cleaning and then carrying out rotary tillage on the bottom of the pond; introducing natural seawater at the mid-to-late May, filtering with a 60-mu mesh wing to prevent fish and shrimp eggs from entering; in early June, sowing spats with the shell height of 0.8-2.0mm at the bottom of the pond; after 10-15 days, replenishing for charging water by combining with spring tide, keeping the usual water level at 0.8-1.0m, and increaseing the water level to 1.4-1.5m at a high-temperature season; regulating and controlling water quality, controlling the salinity to be 25-30 and the pH value to be 8.2-8.8 as well as the transparency to be 30-50cm; in the overwintering period, keeping the water level of the pond to be above 1.5m, and controlling the dissolved oxygen of the pond water to be not lower than 5mg/L; and capturing when the offspring seeds grow to about 1cm of the shell height. The invention has the characteristics of directly sowing at the bottom for temporally culturing, ensuring that the offspring adapts to the bottom material environment in advance, reducing the mortality rate of the shellfish during the culturing, and being capable of improving the survival rate of the offspring seed to 70-80 percent.
Description
Technical field
The present invention relates to the mariculture field, be method for temporarily cultivating in the middle of a kind of intertidal shellfish seed that increases the intertidal shellfish weed survival rate by regulation and control substrate and water quality environment, support temporarily the centre that is particularly useful for intertidal shellfish seeds such as mercenaria mercenaria linnaeus, blood clam, clam, scallop.
Background technology
China has very long coastline, has a large amount of suitable beach that carry out aquaculture and the neritic areas can be for exploitation, at present on shore reclamation mainly based on the extensive aquaculture of intertidal shellfish.The output of intertidal shellfish aquaculture accounts for about 82% of China's mariculture gross yield, and principal item is variegated clam, clam, blood clam etc., and the kind of introducing exploitation has scallop, mercenaria mercenaria linnaeus etc.In order to satisfy the demand of large-scale cultivation to seed, the aquatic science and technology workers have captured the technical barrier of multiple shellfish hatchery.Yet support link in the middle of the seed does not temporarily solve all the time preferably, traditional way is to hang bag in high 0.8～2 millimeter stage of seed shell in the pond to support temporarily, move on to the sea area behind high 2 millimeters of the shell and hang bag, seed is reached faster culture that to put seedling requirement specification shell high about 1 centimetre, but survival rate is lower, generally have only 10～20%, good can reach 30%.So all need a large amount of close shellfishes to grow seedlings every year, satisfies the demand with huge radix, caused increasing of cost virtually.
The present invention is based on the ecological habit of intertidal shellfish, in conjunction with company's prior art, by the method that the end is broadcast, uses a series of technological means that survival rate has been brought up to 70～80%.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, provide a kind of in the pond end broadcast the method that the intertidal shellfish seed is supported temporarily in the middle of carrying out, utilize this method to make to form motility rate temporarily in the middle of the intertidal shellfish seed to reach 70～80%.
The present invention is achieved by following technical proposals: select husky many mud few, silt content is done storage pond, holding pond in the pond more than 70%.Behind the thoroughly clear pond, rotary tillage is 5～10 centimetres at the bottom of the pond.Mid or late May is advanced nature seawater, and with 60 orders sleeve net filtration, prevents that the fishes and shrimps ovum from entering.At the beginning of 6 months, high 0.8～2.0 millimeter young shellfish of shell is broadcast at the end, puts seedling density 100～1,500,000/mu.After 10～15 days in conjunction with flood tide replacement water, every damp replacement 50%.Water level remains on 0.8～1.0 meter at ordinary times, and high temperature season is flooded to 1.4～1.5 meters.Regulation and control water quality, control salinity 25～30, pH value 8.2～8.8, application company " unit cell algae directive breeding technology " control transparency is at 30～50cm.Overwintering period pond water water level remains on more than the 1.5m, and in time sweep away snow snowy day, and application company " subglacial biological enhancementoxygen technology " control pond water-soluble oxygen is not less than 5mg/L.Seed is long to be caught to the high 1cm of shell left and right sides Shi Qi.
Compared with prior art, the present invention has following beneficial effect: directly broadcast temporarily and support at the end, makes seed adapt to bottom environment in advance, has reduced the lethality when becoming shellfish to culture, and survival rate brings up to 70～80%.
Embodiment
The invention will be further described below in conjunction with supporting embodiment in the middle of the mercenaria mercenaria linnaeus seed temporarily.
Select husky many mud few, silt content is done the middle storage pond, holding pond of mercenaria mercenaria linnaeus seed in the pond more than 70%, preferably selects draining convenient, and natural biological bait is abundant, water nonpollution, and away from the pond of advancing Haihe River mouth, the pond size is advisable with 30～100 mu.Behind the thoroughly clear pond, rotary tillage is 5～10 centimetres at the bottom of the pond before the water inlet.Mid or late May is advanced nature seawater, and with 60 orders sleeve net filtration, prevents that the fishes and shrimps ovum from entering.At the beginning of 6 months, high 0.8～2.0 millimeter mercenaria mercenaria linnaeus children of shell shellfish is broadcast at the end, throws in density 100～1,500,000/mu, and seed is thrown in and adopts dry method to broadcast seedling, evenly throws in along set mark, and seed is thrown in and avoids bad weathers such as burning sun, heavy rain.Throw in the clam seedling and begin replacement water after 10～15 days, every damp replacement about 50%, water level remains on 0.8～1.0 meter at ordinary times, and high temperature season is flooded to 1.4～1.5 meters.Regulation and control pond salinity water 25～30, pH value 8.2～8.8, application company " unit cell algae directive breeding technology " control transparency is in 30～50cm.Overwintering period pond water water level remains on more than the 1.5m, and in time sweep away snow snowy day, and application company " subglacial biological enhancementoxygen " technology control pond water-soluble oxygen is not less than 5mg/L.The clam seedling is long catches sale to 1cm left and right sides Shi Qi.
