Abstract
A method for improving quality of freshwater fish by using seawater to adjust salinity of a circulation water culture system, comprising the following steps of farming the freshwater fish through the circulation water culture system; and periodically and orderly farming the freshwater fish which are farmed as goods in dispersed ponds in the circulation water culture system having a certain seawater for a segment of time by stages, wherein the certain quantity of seawater is added to the circulation water culture system so as to adjust the salinity of the water in the circulation water culture system. Compared with the prior art, the invention has the following advantages: the method realizes the living purification of the freshwater fish, improves the quality of the fish meat, improves the culture density and farms 50-70 kg of fish in each cubic of water; multiple batches of fish can be farmed, so the economic efficiency is high; and the cost is low, and the method is simple, so the invention can be easily operated.
Description
Technical field
The invention belongs to the freshwater fish culturing field, relate in particular to and improve commodity fresh-water fishes quality technology.
Background technology
Freshwater fish culturing has dual mode in the prior art, and the one, the pond culture that disperses, the 2nd, circulating water cultivation.The deficiency of the pond culture that disperses is; Because the environment of breed region and water quality is different, and the difference of bait, makes the quality of finished product fish uneven, the standard that has even do not reach food hygiene.Circulating water cultivation can be realized industrial aquaculture, and its quality can reach certain standard, but the quality of fish is also not fully up to expectations.So how improving the quality that cultivates fresh water fishes is technical issues that need to address of this area.Have the breed fish of pair water quality inferiority before listing, to carry out the process that primary purification is cultured abroad, its purifying aquaculture just is limited to and is placed in the good cultivating system of water quality and cultures a period of time culturing fish, makes its requirement that reaches food hygiene, the change of quality essence useless.
Summary of the invention
The object of the present invention is to provide a kind of method that improves commodity fresh-water fishes quality.
The present invention realizes through following technical scheme:
Regulate the method that the circulating water culture system salinity improves the fresh-water fishes quality with seawater; Comprise with circulating water culture system and cultivating fresh water fishes; Circulating water culture system comprises breed pond, mechanical filter unit, biological purification plant, chlorination equipment, aeration device and the register that connects with pipeline; Fresh-water fishes are included in and disperse the pond to culture into the fresh-water fishes of commodity; It is characterized in that saidly regulating method that the circulating water culture system salinity improves the fresh-water fishes quality with seawater and comprising also the fresh-water fishes that disperse the pond to culture into commodity are cultured a period of time again that in the circulating water culture system that adds a certain amount of seawater adding a certain amount of seawater in the said circulating water culture system is the salinity of regulating water in the circulating water culture system.
Method of regulating circulating water culture system salinity raising fresh-water fishes quality with seawater according to the invention; It is characterized in that saidly will disperseing the fresh-water fishes that the pond cultured into commodity in the circulating water culture system that adds a certain amount of seawater, to culture a period of time again; Be stage by stage, regularly and in proper order culture; Said is that salinity with fresh water in the circulating water culture system is divided into 3-5 stage from low to high stage by stage; The salinity of fresh water is 3-5% in the phase I circulating water culture system, and each follow-up stage all increases 3-5% on the basis of salinity previous stage; Said regularly is at each stage breeding 5-8 days; It is to culture by the phase I that said order is cultured, and gets into second, third successively and follow-up phase is cultured.
Method with seawater adjusting circulating water culture system salinity raising fresh-water fishes quality according to the invention is characterized in that said fresh-water fishes comprise carp or crucian.
Principle of the present invention is: utilize circulating water culture system the finished product fish to be carried out the raising of certain hour; Can improve the food hygiene situation of disperseing to culture fish, simultaneously, the water that circulating water culture system flows can improve the quality of fish; After adding a certain amount of seawater in the water in circulating water culture system; Because the variation of internal has taken place to have in water quality, not only have the effect that purifies live body, have more the effect that improves the live body meat quality.Fresh-water fishes are directly put into the seawater raising can not become alive; Therefore; Take order to change the mode of salinity, fresh-water fishes are progressively adapted to, finally reach the degree that in the water of certain salinity, to survive; Realize becoming before fresh-water fishes go on the market the fresh-water fishes of mariculture, thereby from improving the quality of fresh-water fishes in essence.
The present invention compared with prior art has following advantage:
1, realizes the live body purification of fresh-water fishes, satisfy the requirement of food hygiene.
2, the water owing to circulating water culture system flows.Can improve the quality of flesh of fish matter.
3, owing to make the raising again to the finished product fish, cultivation density can improve, and every cube of water body can be raised the 50-70kg fish, and every year can many batches of raisings, raise back fish products matter and improve, and have very high economic benefit.
4, cost is low, and method is simple, easy operating.
Description of drawings
Drawings attached one width of cloth of the present invention,
Fig. 1 is the sketch map of the embodiment of the invention.
In the accompanying drawing, 1, raise the pond scattered, 2, circulating water culture system I, 3, circulating water culture system II, 4, circulating water culture system III, 5, circulating water culture system IV, 6, high-quality marketable fish.
Embodiment
Embodiment is described further the present invention below in conjunction with accompanying drawing:
Shown in Figure 1 is to set up four independently embodiment of circulating water culture system; Four independently circulating water culture system be respectively circulating water culture system I2, circulating water culture system II3, circulating water culture system III4 and circulating water culture system IV5; Wherein the salinity of water is 5% among the circulating water culture system I2; The salinity of water is 10% among the circulating water culture system II3; The salinity of water is 15% among the circulating water culture system III4; The salinity of water is 20% among the circulating water culture system IV5, the carp that disperses to culture is collected the back in circulating water culture system I2, cultured 5-8 days earlier, and the carp that will in circulating water culture system I 2, culture 5-8 days is then put into circulating water culture system II3 and cultured 5-8 days again; In circulating water culture system III4 and circulating water culture system IV5, all cultured 5-8 days more respectively successively then, what from circulating water culture system IV5, go out the pond is exactly high-quality carp.
