If your site has a pond, you can breed fish. Fish farming in ponds is an interesting and profitable occupation. Almost everyone in my childhood was the aquarium. However, not all have kept this hobby for life. But it’s not terrible. Importantly, the idea of breeding fish in captivity.
The fish habitat is water. This is for anybody not a secret. But few people know exactly what should be the water that the fish stay away. If you were observant, you might notice: a large grassy puddle, and her boys caught a whole bunch of carp. Or another example is a large lake with picturesque shores, and no matter how much I wait with bait – no one bites. What is the reason?
Back to the aquarium. Remember, if the water in the aquarium began to thicken – the fish began to die. Besides, you regularly use the microcompressor, enriching the water with oxygen. Sometimes heated up the reflector, so that your animals did not freeze. Tried time to feed, feed purchased, depending on the species of fish. In a pond all the same. The fish grew and bred, she needs pure water enriched with oxygen. The water temperature must conform to a certain norm. Keep in mind that the fish in the cold is not propagated. Even fish need a good forage base. Continue reading
Recently in fish farms of Ukraine, the cases of emergence and spread of protozooses. caused by the ciliated infusoria. The spread of disease contributes to the pollution of waters with organic substances, violation of fish and animal health requirements.
For modern aquaculture is characterized by a sharp deterioration of water quality in ponds. This considerably weakens the body of fish, lowers its resistance to diseases, promotes the accumulation of pathogenic microorganisms, which when tight crop of fish raises the risk of a protozoal disease.
We investigated parasitological situation in feeding and nursery ponds of fisheries Krinichansky. This is a full-cycle farm with a cascading arrangement of ponds. The total area of the ponds is 465 ha. Water is pumped from a selection of water from Dneprodzerzhinsk reservoir and Wet of the river Sura. The objects of fish farming are carp and silver carp, which are grown in polyculture. We used the classical method of complete parasitological dissection of fish ( Bykhovskaya-Pavlovskaya. 1969). When conducting parasitological studies in carp yearlings during the summer period were found several species of ciliated infusoria: Trichodinella epizootica. Trichodi na acuta and Ichthyophthirius multifiliis. Extensionactivity (EI) tradename reached 100 %, the intensity of invasion (AI) – 4,5±1,20 instances on the fish. Continue reading
