Description
Technical field
The present invention relates to a kind of regulate and control method of sea pond ecologic breeding, especially a kind of method of preventing and treating of lichen in sea water culture pond.
Background technology
We know, moss is a kind of silkweed.Begin the breeding growth when spring is warm, grow nonparasitically upon another plant as hair in early days at the bottom of the pond, color is dark green.After heavy rain, weather is fine, and water temperature is suitable, and moss is a large amount of breedings (water temperature is grown fast especially more than 23 ℃) just, in the outstanding Zhang Yushui of net.Become flocculence when old and feeble and fly at the water surface, be yellow-green colour, feel is satiny.Moss breeds in a large number in the breed pond, can seriously consume the inorganic salts in the water body, other planktonic organism and zoobenthos have been suppressed, it is thin that water quality becomes, and causes natural bait to lack, and influences the growth of aquaculture product, and water quality is thin, transparency is excessive, and sunlight shines directly on the aquaculture product, and its growth is caused disadvantageous effect.When moss breeds in a large number culturing the pond, how dark Chi Shuiyou is, and how high moss just have, covering mud as dragnet is coated with, therefore the shellfish that culture the bottom can be choked to death, and products such as the fish of other breed, shrimp, crab also can be snarled by algal filament influence it and look for food and extremely, reduced surviving rate.Along with the rising of water temperature, temperature, the moss death of in the pond, rising, it produces toxic gases such as hydrogen sulfide in decomposition course, improved the ammonia-nitrogen content in the water, has reduced oxygen in water content, can cause that aquaculture product is poisoned, hypoxia death.At present, the measure that moss appears in the pond is cultured in prevention: after annual aquaculture product results finished, Jiang Chishui drained, and cuts out top layer mud with dozer, and the sterilization of clear pond; When receiving the liquid manure pond spring, look the pond liquid manure degree rational application of fertilizer, receiving water can not be too shallow, and fertilizer will dissolve, and full pool spilling head is even, avoids fertilizer to sink to the bottom.Treatment process after in culturing the pond, moss occurring: when culturing that the fishery products seedling is not put in the pond in a suitable place to breed and when a large amount of moss occurring, every mu of water surface will sprinkle a few kilogram of raw lime moss is killed, and drains Chi Shui then, again Na Shuifeichi.When a small amount of moss occurring, raise pond water water level when culturing that the fishery products seedling has been put in the pond in a suitable place to breed as much as possible, breeding unit cell algae grows fat Chi Shui, suppresses the moss breeding.When culturing that the fishery products seedling has been put in the pond in a suitable place to breed and moss in the pond during a large amount of breeding, use medicines such as prometryn, moss are clean, copper sulfate, sodium pentachlorophenate to remove.In addition, also can adopt powership to travel and in the pond, produce turbid wave, or the yellow mud of splashing, make pool water change muddy, reduce water transparence, suppress the moss growth, and adopt instruments such as bamboo pole or special hardship are harrowed, net drags for manually to drag for and remove.Though unslaked lime is spread in employing or medicine can kill moss, also to repeatedly change water brush pond, and Na Shuifeichi again, make troubles to operation, increased aquaculture cost, and medicine works the mischief and has side effects easily to its aquaculture product.Employing produces turbid wave or the yellow mud of splashing inhibition moss growth and manually drags for and remove, and exists the big deficiency of labor strength.
Summary of the invention
Kill moss cost height in order to overcome the prior art Chinese traditional medicine, and easily breed variety is worked the mischief and has side effects, manually suppress, remove the big deficiency of moss labor strength, the invention provides a kind of method of preventing and treating of lichen in sea water culture pond.This prevents and treats not only advantages of simple of method, operation feasible, and cost is low, and can provide abundant natural bait for the aquaculture product of culturing in the pond, helps the growth of aquaculture product, improves surviving rate.
The technical solution adopted for the present invention to solve the technical problems is: a kind of method of preventing and treating of lichen in sea water culture pond, it is characterized in that: in culturing the pond along be arranged in parallel fixedly well rope rope more than two of culturing pool direction of flow, fixedly the rope body two ends of well rope rope are fixed at the bottom of with fixture and described pond, on the fixedly well rope rope rope body between two inboardends, be fixed with some cursory, adjacent two fixedly is intrinsic some multiply seedling ropes between the well rope rope, accompanies the marine alga seedling between the thigh of seedling rope and thigh.
Described be clipped in the seedling rope the thigh with the thigh between the marine alga seedling be river hedge seedling or sargassun seedling.
Fixing used fixture is timber or stone stone roller or anchor at the bottom of the rope body two ends of described fixedly well rope rope and the described breed pond.
The present invention adopts cultivation hanging on the raft ocean macro in culturing the pond, ocean macro after the growth keeps the sun off, reduced water transparence, suppressed the moss growth effectively, prevented the light direct projection simultaneously, for breed variety provides comfortable water temperature and good growing environment, set up the new eubiosis, help the growth of aquaculture product.The large ocean algae of Yang Zhiing is again the natural bait of aquaculture product simultaneously, has reduced aquaculture cost.
The invention has the beneficial effects as follows that method is reasonable, cost is low, and operation is simple and feasible, the fast growth of fishery products, surviving rate height.
