Select bodily form to be stalwart, the fish with bright color
Selected the goldfish of any variety, should all select fish's body to be wide and strong, chest, belly, tail fin are complete, the tail opens the great one smoothly. Without fish of the dorsal fin, the back will select smoothly, not have incomplete dorsal fin or tubercle. And the color of the fish should select the red one delicate and red, the white one is pure white, the blue one is azure, the black one is pitch-dark, flower's person color is mediated, the pattern is careful, can be called five flowers if there must be the blue ones. Whether some fish's body is half red, half black or the body is red and the black one of edge of the fin, very beautiful for the moment, will turn into the all red one soon in fact, predict.
In selecting the fish, the peculiar outstanding one in characteristic, bodily form or color to it, should break a rule and record selecting, observe and train.
There are no fish of the disease in health to select
Generally speaking, in the pool (basin) China moves about actively, gregariously, bodily form is plump, the chest, abdomeinal fin opened and often rowed and moved smoothly, there is no white point on one's body, have no galley proof mucus of white fine hair, the tail, scale do not have blood silk, fester, seldom float on the surface of water, lie on one's side either, handstand, sink ins and outs, the stool turns black but a thick one is the healthy fish, there are fish looking for food, the above-mentioned situations can be chosen boldly.
Fish selecting the characteristic to be obvious
Various fish have a characteristic of this assortment: Very red such as selecting the elderly person for whom a birthday celebration is being held very beginning, large meatball, crane, goose's red assortment of very beginning, they all have sarcoma and become famous with the head, so, it is most developed, spacious that we want to select sarcoma which the gill cover of the head. In addition crane very red, goose head getting red to have getting red fish of sarcoma with red and very up right and foursquare (whether top of the head color relatively dark at the young fish) Person the top grade,select by scale fish pearl should pay attention to heavy, tail twoes small,tails big good. But no matter big end or small end, should select the head to be sharp and small, it is not scarce that the pearl scale is thick, it is neat until the back to arrange, but the scale can't erect, otherwise the majority sets up the disease for the scale. The belly expands thickly round, the end is smooth, this kind of characteristic is purebred. Bubble or dragon's eyeball, all named after characteristic of the eye, so, should select bubble round and big and well-balanced, the bubble quality is soft and the transparent one. While selecting dragon's eyeball, should select the eyes one big and stressing the person who likes piece.
Breed fish and raise water first, has already become experience not fought for. OK in the family " Raise " A good jar is limpid and having no water poisoned to seem essential. The family breeds fish and is different from the fishing ground to breed fish. The space of water body is narrow and small, and require water quality to be limpid and transparent, easy to view and admire goldfishes. It is for making the goldfish grow fast that the fish farm breeds fish, supervise and see water quality when there is professional fish man-hour, the water body is spacious, suitable for goldfish's growing up. The family has one's own advantages to breed goldfish. Such as the water temperature, because the family breeds fish generally indoors, is free of blowing and raining,etc.. Have it in the family breeds fish because the water yield is relatively small again, convenient water quality is observed and controlled with the medicine. The family breeds goldfish and raises water to mainly relate to five following factors.
Filter the system: Because density that family breed fish generally relatively heavy, simple to rely on water body oneself decompose very much difficult to remove impurity, wastes of the ink. Can set up one good filtration system effective water quality of keeping. The good filtration system can filter the way by comprehensive chemistry, living beings, physics,etc.. Chemistry is filtered to rely on special-purpose medicines to condense suspending in water smallly the impurity together, make it precipitate or be filtered by physics. The living beings filter and is decomposed wastes in water by the beneficial biological fungus group in water, it is harmless to resolve the harmful substance into. Physics is filtered to absorb, strain and get rid of the impurity particle through the small hole filtering the material. To goldfish's characteristic and the condition that the family breed fish, can use the following ways to set up the system of filtering. According to the Shui nationality's case size, dispose the external filter, can carry putting or filter the barrel. The flow of water can be found in the explanation of the water pump. Can 7 about water systemic circulation per hour generally speaking, for example: Long 80, 40 wide, the volume of the Shui nationality case of 40 in height is 128 liters, filter the flow of the water pump and select in 900 liters per hour. As to the Shui nationality case more, for prevent rivers from to be pace too strong, propose, entry into water mouth install the built-in filter additional, increase the return bend on the water outlet, in order to reduce the impact of the goldfish of the rivers. Filtering the box ' Barrel) China puts biochemical sponge, active charcoal, and change according to the degree of pollution of water body. But too change frequently, is unsuitable for the setting-up of the beneficial biological fungus group, generally change once in January.
The living beings decompose: Among at natural environment,it flow river place enclose for a large number of beneficial bacterium group, they can decompose the metabolite that the organism in water produce and outside pollutant. In order to keep water quality clean, harmless. Set up beneficial bacterium group among the Shui nationality case, may keep water quality for a long time, needn't change the water often. Add, nitrify bacterium to set up living beings decompose the systematic shortcut among the Shui nationality case. The ones that sold nitrify bacteria to fall into two categories, nitrified bacteria actively and nitrified bacteria artificially on the market. It regards fungus group of living subject as the main material to nitrify bacteria actively. It is by already nitrifying the material of bacterium's growth while promoting water to nitrify bacteria artificially. Nitrify bacteria actively and get up for time of result short, usually within 2-5 days according to the water temperature, the water temperature is the most obvious on function of 25-30 degrees. But holding time is short, do not usually exceed 12 months. Nitrify bacteria and does not include the active bacterial strain artificially, it is long, usually in about 2. But get up for time of result longer. Before setting up the biosystem, can combine and use water quality to clarify the use of pharmaceutical.
