Achieving Ionic Equilitbrium in Marine Fish

For intestinal fluid therapy, it is essential for intestinal water absorption to produce luminal divalent carbonate deposits in the intestines of seawater fish (Grosell, 2006; Grosell, 2011; Kurita et al., 2008; Walsh et al., 1991; Wilson et al., 2002). Formation of the lumen sediment requires a high concentration of divalent ions and a chemically favorable high pH. The high divalent ion content required for precipitate formation is provided by the high calcium content of the absorbed sea water, which varies from 3 to 15 mM depending on species (Fuentes et al., 2006; Genz Et al., 2011). ; Wilson et al., 2002).

The osmotic pressure controller actively or passively adapts its osmotic pressure to its environment. Most ocean invertebrates are permeable mixtures, but their ionic components may be different from seawater. Osmolality regulators tightly regulate the osmotic pressure of the body. This is always constant and more common in the animal kingdom. Despite the presence of salt concentration in the environment, the osmotic regulator can actively control the salt concentration. An example is a freshwater fish. Several fish have evolved the osmotic regulating mechanism to survive in various aquatic environments. When they live in fresh water, their body tends to absorb water as the environment is relatively low permeability, as shown in Figure 1. In this hypotonic environment, these fish do not drink too much water. Instead, they pass large amounts of very dilute urine and achieve electrolyte balance through active transport of salt in sputum.

Aquarium fish are freshwater fish. Freshwater fish are fish that spend their entire or whole life in freshwater, such as rivers, lakes, and lagoons, with salt concentrations of less than 0.05%. These environments are different from marine environments in many ways. In order to survive in freshwater, ornamental fish requires extensive physiological adaptation. · Please do not put fish in the tank. Fish can grow to 1 ft and require more space to swim. Even though swimming is fast, fish give out a large amount of garbage. That is, a lot of water is needed to dilute the garbage. This means that large amounts of bacteria convert waste into less hazardous chemicals. These things need a large aquarium
