Characters of the physical nature of water in fisheries in Lincolnshire
How water responds to temperature changes
How water functions as it warms and cools is essential. First, it takes much energy to heat water, which then is relatively effective at retaining the heat contrasted with the atmosphere. This means that in reality, water is a very stable environment. For example, in temperate areas, the air temperature could be 10°C at 2 a.m. and 27°C at 2 p.m. So any land mammals have to tolerate a 17°C change in temperature over 24 hours. A reasonable sized still-water in the related area maybe 18°C at 2 a.m. and 19°C at 2 p.m. In deep water, it will be cooler and even more steady. This stability is of high benefit to cold-blooded creatures such as carp for sale and tench for sale because their physique temperature is connected to that of the water. This fact can be essential and should be remembered when transporting fish from one water body to a different one, as carp for sale and tench for sale find it tough to tolerate sudden changes in water temperature; which is recognised as thermal shock. As most liquids cool, the particles within them become less active, and the length between them is diminished. As a result, the fluid becomes ever more solid as the temperature drops and eventually freezes to a solid. We know that a solid should be thicker than a liquid and hence the frozen solid sinks through the fluid or forms on the bed. This operates for all fluids except for water. As you chill water down towards freezing, it behaves in precisely the way you would expect, with the colder, more solid water sinking to the bed. This happens until the water is at approximately 4°C (actually 3.94°C), at which period further cooling causes the water to be less dense. This signifies that water cooled from this period on actually starts to raise upwards. When it freezes at 0°C it is still less dense than the somewhat warmer water below so the ice profiles at the surface; the solid water floats on the water as ice. It is a unique molecule to behave in this way. The reason water acts like this is all to do with the electrical charges in the water particle. As the particles cool and become less mobile, they start to form into a structure stabilised by the draw of the positive and negative charges in them. This structured framework is very stable and produces spaces between the particles. Hence it is less dense than the slightly less stable water at 4.1°C. On any still-water, as the temperature drops to freezing, frozen water patterns as ice on the surface and denser water at 4°C sinks to the bottom. If the cold weather continues, then the ice at the exterior may get denser, as more water freezes, but it also creates an insulating layer. This protects the rest of the water and therefore ensures that at the bottom of the water body, more in-depth than around 1.25 m (4 feet), there is always a layer of water at 4°C or higher. This is where most of the carp for sale and tench for sale will be found during this season and they thereby obtain a differing degree of protection from freezing water. The action of water as it changes in temperature has additional profound effects on life in still-waters.
