Description
Technical field
The invention belongs to technical field of shellfish culture, be specifically related at the bottom of spat, broadcast equipment and operating type, particularly relate to a kind of spat offshore bottom broadcast system and operational method thereof.
Background technology
It is that new development of rising in recent years is fast, a kind of breeding way of successful that Releasing and enhancing is broadcast at the end, and now large-scale promotion uses.Become the most important aquaculture model in Huanghai Sea and Bohai Sea, the 1-3 month in annual 10-12 month to next year, the spat broadcast of the end is broadcast ship the end of by and spills into mariculture area, broadcasts the subject matter that operation exists at the bottom of existing spat:
One, spat temperature of exposure and dry is long, and spat is broadcast in ship live well process being transported to the end, and dry dew reaches more than 1 hour often, and especially the low temperature in December and cold wind injure greatly to the spat of dry dew;
Two, spat carries out the end by plastic box and broadcasts ship and enter cabin, extra-vehicular working, puts, enter in cabin, extra-vehicular working operation process in live well owing to piling up, and tramples that to hinder seedling phenomenon serious;
Three, seed transport and the end, broadcast in process, and in live well, the plastic box of splendid attire seed is piled up intensive, and cycle water and oxygenation are consumed energy greatly, and partial water is blamed with seed survival up to standard;
Four, ship power consumption is broadcast greatly in transport and the end, and cost is high, and the amount of labour used is great, and intensity of workers is high.
In sum; sowing aquaculture Industry Model development at the bottom of the scale of serious restriction shellfish is broadcast at the bottom of existing spat; be badly in need of mechanized operation and substitute Traditional Man work pattern, improve spat survival rate and production efficiency, reduce recruitment number, reduce labour intensity and production cost.
Summary of the invention
For solving an above-mentioned industry difficult problem, the invention provides high, the energy-efficient spat offshore bottom broadcast system of a kind of weed survival rate and operational method thereof.
