Be in our country, from of old, red is being represented lucky, festival, and viewing and admire a fish gulesly to be like parrot of goldfish, bright and beautiful carp, beautiful arhat, blood to wait is more times suffer people to love. Recently, the friend that a lot of raising view and admire a fish asks me, look of the body when oneself Yu Gang is bought is fresh, after can raising period of time, color becomes shallow gradually, some are complete even " fade " , how is this to return a responsibility after all?

Above all, by its basically the genetic element of oneself decides quality of the bodily form that views and admire a fish, style, but the different level that grows in the fish, its style quality also is constant change. This among them the most remarkable is the juvenile in goldfish, bright and beautiful carp to phase of half adult fish, have one individual lubricious apparent change " turn color period " , this paragraph of time is the crucial period that piscine character discretion forms, if feed is proper, run do sth in the proper way, can make quality of piscine bodily form, style more perfect, its view and admire value and commercial value to be able to increase a class.

Next, environmental element is the main reason that affects piscine style quality. Different water system environment, its acid-base value, contains deliquescent gas, organic compound, mineral each are not identical. Even if the fish of same breed, grow in different relatively stable water quality environment, the difference of its style quality also is very big. Some pisciculture ace sees the fish can be spoken roughly producing area, the mainest basis is the distinction on quality of bodily form of different place fish, style. The goldfish character that the goldfish that typical case is the real estate such as Fujian, Guangdong compares northward breed aquatics generally is close friends, style quality wants gorgeous.

The 3rd, the mutation breed that artificial cross forms, if popular 7 variety are red in recent years a parrot of cap, blood, heart. Because pass factitious control,this kind views and admire a fish, undertake akin or heterogeneous cross and aggrandizement conciously the mutation gene of certain respect, make characteristic of lubricious blood-red of lovely, body stabilized its bodily form to come down gradually. Hematic parrot is become by cross of the red devil fish of kind porgy division and blow hole fish, the seed selection that passes period of time is optimized, of a formation independence view and admire piscine breed.

The 4th, add in artificial formula feed grace the practice of composition already was applied extensively, have certain effect. But different manufacturer place adds grace composition also each are not identical, grace like that one day already composition (like maize gluten pink, red turnip element, shrimp red element) ; Also have artificial synthetic (be like kind of red turnip element, jia Lisu is red, industrial synthesis pigment) . According to feed of Wuhan industry institute the department is opposite view and admire a fish (parrot of goldfish, bright and beautiful carp, blood) in group experiment of contrast breed aquatics makes clear, natural grace the effect of red element of the maize gluten in composition and shrimp is better, the other additive such as element of excel red turnip. Artificial synthesis pigment adds a capacity small, but the effect is not apparent, some synthesis pigment adds a quantity to be in when exceeding one times above, piscine body is fast and erubescent, after out of service counts day, style quality becomes low, mortality heighten. The experiment proves: Be in turn the juvenile of color period, need not add painstakingly in feed grace composition, but content of crude fat, thick protein wants tall, content of vitamin, calcic, iron wants to abound, and should digest easily absorb, had better feed Peng to change feed so. Be in blame turn the fish of color period, cast hello nutrition is balanced reasonable add natural grace the bait makings of composition, piscine body is in 3 weeks or so to appear commonly more apparent grace, become angry the effect; Hello add excessive synthesis to grace the bait makings of the agent, criterion a week left and right sides has namely grace the effect, but to piscine body bigger 損 is killed.
