The effect of water temperature on the biting fish

Every fisherman, whether he is a fisherman with experience or just starting to comprehend fisheries science must have been one of those days where he couldn’t catch any fish, and fishing was spoiled. How could that happen? Factors can be many: cloudy, the atmospheric pressure and the pressure in the water, strength and direction of the wind. Today, we’ll talk about the nuance, as the water temperature, because it changes the pressure in the water, as we know from school physics course. Let’s deal.

When raising or lowering the temperature of the atmospheric pressure should decrease or increase in water temperature. However, due to the structure of water, and to be more specific – heat capacity of water, its temperature does not change so rapidly and greatly as the air temperature.

How is the temperature change of the water? It’s simple: the wind catch the water to one shore of the reservoir and mixes it and causing surges wind flow. As a result, the mixing water, and therefore temperature change.

From the above it must be concluded that the change in the wind direction and its strength leads to a change in water temperature. Naturally, most strongly and quickly reduce the temperature of the Northern and North-Eastern winds.

Now let’s see how it relates to the fish? The temperature of the water and air really affect the fish, because it is from these two parameters depends on the appetite of the fish and its activity. Without any changes the fish can migrate gradually decreasing or increasing ambient temperature. With a sharp jump more than 3-5°C, which may occur during the transportation of fish from one pond to another, the fish are most likely to get sick and die.

No less important criterion is the availability of oxygen in the water, which also depends on the temperature of the water: as the temperature decreases the amount of oxygen increases.

In the result above we can sum up: the fish responds to changes in water temperature within fractions of a degree. It seems to be not a significant change, but it can leave you without a catch.

But not all fish are equally tolerate a decrease in temperature. For example, in some species it acts as a sedative, causing hibernate (a good example is the burbot in the summer); and in other causes increased appetite (carp in summer), increase of oxygen in the water. Let’s move on to the specifics. Lowering the temperature causes the activity of such fish as perch, burbot, trout, roach, roach, roach. Lowering the temperature depressing effect on carp, carp, tench. The temperature increase has a positive effect on carp, carp, crucian carp, tench, pike.

Here we must mention this important point which was noticed by fishermen in the last century: «If white fish is not answering – customize the gear on the predator». If you specify the – pike, perch, walleye, burbot.

Well, with the effect of temperature figured out, now let’s move to «universal» temperature for fishing. Alas, but it, as such, no. Can only say one thing – most of the carp in our fresh waters are well fed at water temperatures from 10°C to 25°C. Here it is necessary to take into account the fact that with increasing water temperature, the digestion rate of the fish increases, and Vice versa, while reducing the temperature of the water decreases.

Most favorable for catching fish is the temperature of 15-20°C. However, this is not a rule, because each fish species has its advantages. Let’s talk more about that. The optimum temperature for the fish (bigger number shows the peak of biting):

trout: 9-12°C;

perch: 13-15°C;

roach, roach, roach: 10-20°C;

pike: 15-16°C;

bream, silver bream, Chub, IDE, perch, Bursch: 14-20°C;

laziness: 15-22°C;

som: 18-22°C;

Golden and silver crucian carp: 18-22°C;

ASP: 18-23°C;

Rudd: 20-22°C;

carp, carp: 23-26°C;

burbot: 4-8°C.

In the hot summer weather, when the water is very warm, such fish as perch, roach, carp, bream and other very bad burn day, hiding in the driftwood, the seaweed and the deep areas of the reservoir where the water is cooler and there is shade. It is best to catch early in the morning, when the water cools down for the night. Caught a bit worse in the evenings. However, in the summer when the weather is nice, the fish actively taking the nozzle with a small and not very strong wind, including day.

If you catch a spring or early autumn, the tactic of fishing can vary considerably depending on the region. This is due to variations in temperature. If they are small, the fish may well be caught during the day, especially in calm weather. This time of year the best fishing there in the warm, Sunny days.

With a sharp temperature drop the fish cease to bite at all.

Well, it’s time to sum up the article. We have found that the best temperature for fish – 15-20°C. in summer the Best fishing is early in the morning. Best fishing in spring and early autumn – day. Don’t neglect these tips, and you catch to go back to fishing!
