Communication of properties of blood and dwelling of a fish

The water environment is extremely changeable concerning the maintenance dissolved O₂ and CO₂. Concentration N which is of great importance respiratory function, also changes over a wide range. Not all fishes are adapted for wide variations to changes of environment.
Oxygen acts as the major ecological factor rendering the big influence on development of some morpho-physiological and biochemical adaptations, the factor adjusting distribution of fishes and limiting their distribution to the nature. Accumulation in water CO₂, N and the raised temperature leads to reduction of linkage O₂ by hemoglobin in respiratory bodies of fishes, hence these factors can favour and interfere with breath.
Accumulation CO₂ in blood can have various intensity. It is connected with quantity of bicarbonates available in blood. The more bicarbonates (an alkaline reserve), the can communicate CO₂ more, the metabolism can be especially intensive.
Such general communication between physiological features of fishes and physical and chemical conditions of environment is observed. Fishes with a high level of oxidizing processes have the hemoglobin sated O₂ at raised partcial pressure. Such fishes badly transfer environment with the lowered maintenance of oxygen, rise in temperature and concentration free CO₂, and also downturn Ñ€Ð½ environments. Increase of an oxidizing exchange in an organism conducts to increase of concentration CO₂ in blood, and it leads Ð°Ñ†Ð¸Ð´Ð¾Ð·Ñƒ, that considerably reduces linkage O₂ by hemoglobin.
Output from such inconsistent position is usually translation of a fish in well aerated water with the lowered temperature. If the temperature of water is raised, it should have not only the normal maintenance of oxygen, but also a significant alkaline reserve that facilitates linkage exhaled CO₂. Such environment is sea water.
To have a high level of an exchange at the raised temperature and the lowered quantity of oxygen and sour reaction of environment, the fish cannot. At it high oxidizing process in fabrics due to water type of breath cannot proceed and it should pass to air breath. If fishes living in well aerated water to translate in conditions with the lowered maintenance of the dissolved oxygen at them quickly enough develops Ð°Ð½ÐµÐ¼Ð¸Ñ‡ÐµÑÐºÐ¾Ðµ a condition (downturn of the general metabolism) leading infringement of many physiological processes. The environment with its features of physical and chemical and chemical character demands the certain fitness of fishes to the given conditions. When environment changes, it makes new demands to an organism which should accordingly will change to not be lost.
But the important role in this process is played also with microcells. For normal realization of respiratory function 5 elements (Fe, Cu, Co, Mo, Zn) are necessary. To receive them it is possible only from an environment.
