Living in the wild tropical fish are not spoiled by an abundance of food, and therefore can long without it. But during the rainy season, forage is enough, this time the fish reach maturity and spawn. In favorable conditions the young grow up without any problems and becomes sexually Mature. The main task of the aquarist is to find a substitute for natural forage, To determine the correct composition of the diet have to be able to distinguish three fish groups.
a) fish feeding on plant food (herbivores)
b) fish feeding on small aquatic fauna, zooplankton and bentoel and plant food (omnivorous)
b) the fish, feeding at an early age small, and later a major animal food and fish (carnivores).
In the natural environment with an abundance of food a certain kind of fish chooses the one that fits him best, and in captivity, fish are totally dependent on what they will offer. So among aquarists can often hear that this or that kind of got used to the unusual stern. However, this can be hidden tricky, because the fish can take the feed of hunger and the addiction to food can lead to later health problems. Good food and regular feeding is especially important for young and breeding fish (manufacturers). Giving the fish a natural food, we thereby satisfy their needs in proteins, carbohydrates, fats, vitamins, mineral homestake. Different is the case with artificial food, which is slowly but surely becoming the predominant element in the diet of aquarium fish. It would have been useful information manufacturer about the components of the feed mixture. Continue reading
The causative agent in fast-flowing water persists for long (in hours). Its virulence is low, as it usually causes disease in immunocompromised fish spawning. After amplification of their virulence by passaging in the body is weakened fish it causes disease in a large number of fish in the form of epizootic outbreaks.
Ehpizootologicheskaja data. Disease in pikes usually occurs within a few days after spawning (March – April). The most susceptible Mature individuals. The perch, bream, roach and burbot the disease recorded in the summer. The emergence of the disease contributes to cold spring, especially during the spawning period of pike. Then the flash increases and reaches maximum development during the summer months. It fades by the end of summer,
Epizootic process can continue in a large body of water (reservoir, lake) for several years and spread to other reservoirs-current water with transportable or migratory fish. The source of infection are sick and dead fish, microbiological. They are contagious from the beginning falls into the water with secretions, or the decomposition of corpses. Most researchers believe that infection occurs via povrezhdeniya the skin, mucous membranes, intestines. Continue reading
