Are the sturgeons adapted to the life out of basin of garden?
In France, the majority of the sturgeons sold for the ornament of Acipenser baeri, are also called Siberian sturgeons. They rather affectionnent water fraiches and oxygenated (in the beginning they live in the estuaries, the rivers and the big lakes).
Ideally, it is thus judicious to prefer the basins which are supplied by a source or a brook. However, in the case of a closed basin, even equipped with a pump of recirculation, one needs at least 3 m3 by sturgeon, with shade or a corner of freshness (thus a certain depth, 90 cm with 1 m seem to be the minimum), if not there is a risk of lack of oxygen during the summer. Avoid introducing small fish trops (less than 30 cm), they are youthful thus very fragile.
Last council: attention with the filamentous algae, they tend to clog hearing of the sturgeons which eat them by seeking their food.

How long can one transport fish of ornament?
For your red koï and your fish, we provide you a bag inflated with the oxygen which gives you more than 24 hours of autonomy for transport. To the need we provide an isothermal packing to avoid too great thermal fluctuations. For the sturgeons or the loves white, the principle is the same one, but the durations of transport divided by two. Try to provide you with a container (standard boiler or plastic case) or we will fix the plastic bag. It is necessary that the dimension of the vat is sufficient to make hold fish flat. In all the cases there will be no splash in the car!

Why classify the koï by rank?
Classification has, B, C of the koï is purely suggestive. For a purist, only the rank has merit the name of koï, or rather of nishikigoï.
However generally the amateurs agree on following classification:
Carpe Koi rank has (or nishikigoi): corresponds to the criteria of classification of the international contests: colors, reasons, silhouette, etc (established rules at the origin by Japanese). Each fish must be able instantaneously to be indexed in one of the recognized families. The carp koi rank AA is the name sometimes reserved for worthy fish to take part in a contest (very rare in France because few amateurs ready to put the price).
Carpe Koi rank b: these koï results generally parents rank has, but they are downgraded, either for a defect of silhouette, or of color, or of distribution of the colors Parfois there are good deals because obviously they are less expensive. It should be noted that even with 2 excellent parents rank has, one hardly obtains more than 1% of descendant rank has (except for certain families with plain dress or the results are better).
Koi keeps C (or koï European): In general they are the remote carp descendants of higher ranks, their colors are more insipid and they do not have reasons not defined well. Raised in pond, they are robust, grow quickly, and are ideal to brighten a basin or a pond if one is interested little in the koï and that one does not wish to invest in more expensive fish.
Finally to finish it is necessary to specify that there is no standard and what relates to the koï, consequently the salesman can easily deceive his customer beginning on the rank from its fish. Thus animaleries are very frequently seen and known signs to sell koï under name koï Japan or koï rank has or Quality has whereas the fish are ranks B to see bottom-of-the-range European koï Then be patient and take your time to choose beautiful fish.

For a koï, the rank of quality have-you it a direct relationship with the source?
In the absolute, the ranks at all do not reflect a source or an geographical area. However the rank has very often come from Japan (sometimes of the USA), the rank B of Asia and from Israel, a little Europe, the rank C come from Europe because it is not profitable to import some besides. Theoretically, one can raise rank perfectly has in France, but the great difficulty rests on the control of the genetic selection, which nobody for the moment manages to do with same quality only the Japanese stockbreeders. Certain importers of koï make enlargement, i.e. that it enlarge the koï rank has to sell them with a higher size. There too it is delicate, (especially from a medical point of view), and only of large specialists reach that point perfectly.

Are white love, silver plated love, effective?
The herbivorous carps, or loves white, are very effective to reduce the algae in a water level. They are rather apprehensive and wild, and become very large in a few years, redoubling effectiveness. They are by far the least expensive solution for those of enters you who have small invaded ponds of vegetation. To know how much fish to introduce, one needs a diagnostic precis according to the varieties of plants present, the rate of invasion and of course, the surface of the water level Contactez us! We disadvise to you introducing love white into the following cases:
- if your basin is small (less than 10 m3): they will have evil to find their balance.
- if the fish are youthful (less than 15 cm): they are rather fragile, and are likely all to die in a few weeks.
- if you wish to preserve a varied and developed flora: they do not distinguish the algae and the plants génantes from those which you planted patiently
The loves silver plated have a filter action. They thus nourish phytoplankton, but their clearing up action is very debatable: indeed more they eliminate the microalgues, more water is cleared up and more there is photosynthesis. Consequently of other microalgae reappear, and water is not really cleared up On the other hand these very original fish from an aesthetic point of view will not damage your plantations. They become also very large, then attention not to introduce them into a too small basin

Are fresh water moulds, effective?
The fresh water moulds filter water to nourish phytoplankton. However their action on the turbidity of the basin is negligible. Introduce them only if you wish to diversify the fauna of your basin, but without expecting a miracle result to clear up water
How to use salt to look after its fish of basin?
Salt (or sodium chloride NaCl) is the first emergency remedy for your red koï and your fish. Salt makes it possible to treat and eliminate quickly the majority from the parasites and external diseases of your fish (disease of the white points, mushrooms, foams, necrose fins, wounds, etc) It also makes it possible to destroy the toxicity of nitrites. It is very economic, does not disturb the bacteria of your system of filtration. As far as possible, salt not iodized should be used. Two possible methods to manage the treatment:
1°) Treatment of the whole of the basin - proportioning must be salt 0,2% (0,3% maximum, which represents 2 kg of salt per cubic meter of water (1000 liters).
Start if possible by renewing 20 to 50% of the water of the basin (attention to the thermal shocks).
Then to pour 1 kg of salt per cubic meter every 12 hours with 3 recoveries, to arrive at 3 kg/m3 in 36 hours (to apply, dissolve salt in a water watering-can of basin). In the event of urgency, to apply 2 kg per m3 in only once.
Let act 2 weeks, then renew 5 to 10% of water each day during 10 to 15 days to eliminate salt.
Caution: Salt does not disturb the water lilies nor the irises. It can make yellow lettuces and the hyacinths. Elodea do not support it, place them separately during the treatment. 2°) Treatment of sick fish by balneation
Proportioning must be salt 2% (3% maximum), which represents 20 G of salt per liter of water.
Prepare your salt in a bucket of a few liters of water of the basin, attention to the weighing of salt! Once dissolved salt, capture your fish with the scoop and place it in the bucket during 10 maximum mn. Supervise fish attentively. If it gives sign of weakness and that it lies down on the side, stop the treatment and give fish in the basin before starting again with an amount less half. If the fish is agitated and tries to jump, it is normal, treat 10 maximum mn. To renew every 2 days in possible alternation with another treatment.

Some easy ways for the small pains
Your koï or your red fish suffers from an open wound (lost scale, scratch, blow of nozzle of héron) or of does one necrose fins? It is necessary to be vigilant, because is a situation favourable with an infection (bacterial, fungic or parasitic).
Here two products on sale in pharmacy, not very expensive and often much more effective than all the very expensive remedies sold in animalery
The BETADINE in GEL (and nonliquid). Delicately whitewash the wound (and only the wound) before giving fish to water.
The POTASSIUM PERMANGANATE: it buys liquid, delicately apply it with a cotton to the wound before giving fish to water.
These products are idéals in alternation with the salt treatment in balneation. There exists two different products, harder to find, very effective in balneation against the fungic and parasitic problems:
CHLORAMINE T and the GREEN MALACHITE, this last often applying in partnership with formol. Proportionings are delicate and depend on the concentration of the solution mother: you with the note refer.
As for the METHYLENE BLUE, it is not very effective for fish of basin, it is preferable to use it only in a preventive and noncurative way.

HEADING AQUICULTURE

With what do nourish you trouts?
The trouts are carnivorous fish which in France are nourished with food riguoureusement controlled, composed of flours and oils of fish whose source is entirely traced, and also of a small fraction of cereals (without GMO). There is thus no flour of terrestrial animals in food for fish. In addition the profession is very attentive so that the standards concerning the dioxane rates are never exceeded, which obliges the food manufacturers to control each batch of wild fish entering the composition of food.

Do you use drugs for fish with the Pisciculture of the Villette?
Our artisanal pisciculture is centered on the refining of trouts. We receive healthy alevineurs and stockbreeders since our small trouts, almost adult. Those finish growing bigger on our premises. In our pisciculture we do not use drugs (thus not antibiotics). In order to prevent the medical problems, we practise a preventive disinfection of the material and fish ponds. These is a rare choice which implies a mortality higher than that of a using breeding of the drugs, but we made this choice with an aim of quality and better communication for our sales. In the case or there is a disease, it should then be identified; Some imply the demolition of the livestock, but it is extremely rare (that never arrived to us), mainly owing to the fact that the diseases of salmonidés are not transmissible with the man. Thus a sick fish is still marketable for consumption. On the other hand certain viral diseases imply that the fish cannot be reintroduced any more in river or pond, in order not to disseminate the disease. Several breedings in France are prohibited of sale of alive fish, on standby of éradiquer the virus (by a assec with disinfection in general).
How does one become pisciculturist, is this an easy trade?
Many young people come towards me to get information about the trade of pisciculturist, or because they have a community project in this direction. It is very open questions to which I then to bring only tracks so that you find even your own answers.
First of all, it should be known that it is a difficult trade and disaster victim, since there are much less pisciculturists today than there is a score of years.
In addition, it is not enough to like fishing and fish to launch out! It is a complete trade: trade, management, red tapes innumerable, deliveries, work in workshop of transformation, maintenance of the material and site (plumbing, masonry, green areas), and finally care with fish. Consequently, it is necessary for all to be courageous (work 7 days a week is not rare), general-purpose, trading, to like nature (but also to like to work all alone in its corner while the others rest!). As for fishing, and well in general a pisciculturist does not have time to go there or if little.
In short, it is an enthralling but difficult trade.
There exists in France excellent formations on several levels: BEPA, Vat pro, BTSA, even second and third cyles university or engineers: information in the centers of orientation, on Internet
The problem lies in the fact that there are much more graduates than of places available on this very small labour market. My council is thus to make studies plus general practitioners as long as you can it, or to specialize in a related die richer in employment (environment, agriculture and green areas, etc). Then, you will be able to always specialize you by taking again a piscicultural teaching on your level.
The result, it is that if you do not find work in aquiculture, you will be able to always find another work while waiting.
Do not forget: serious, motivation and courage (before even passion) are the keys of the trade.
