Carp fishing is possible at low temperatures, but the main rule of sport fishing is – caught fish should be returned to the water
Fishermen always have interesting experiences and the advice they give to other fishermen with less experience, but also to people who just want to do fishing. English anglers certainly have the most experience in introducing new ways of fishing, introducing novelties in sport fishing and fishing aids (among other anglers from Europe). For example, they introduced balls, wegler floats, electronic recoil indicators, match rods and many other things into carp hunting. In England, for example, fishing for “peaceful” fish is more popular than hunting for predators.
The pike is the most popular predatory species in English waters. Catfish and perch are also popular, but these are non-native (imported) species.
Fish are organisms whose body temperature depends on the temperature of the environment in which they live (homeotherms). The activity of fish depends on the temperature of the environment. Fish are more active if the temperature is higher and vice versa. It has been experimentally determined that perch at a temperature of 20°C empties the intestinal tract 24 times a day, i.e. during 24 hours. The perch also empties its bowels only once at a temperature of 4°C. However, this does not mean that the activity of the fish increases with increasing temperature. There is actually an upper limit at which fish reduce their activity when the temperature increases further. As the temperature drops, so does the fish’s metabolism. It has long been known that at low temperatures, fish reduce their activity to a minimum (around 4°C and below). English fishermen have proven that fish take food even at low temperatures. They proved that, for example, carp takes food at a temperature of 1.6° C. That is why carp fishing is possible at low temperatures. Of course, anglers do not expect spectacular catches, but you can catch carp and some other species at low temperatures. English anglers have noticed that pike also behave differently at lower temperatures. In these conditions, the “kedered live fish” (bait for pike) is weakly mobile or immobile. Therefore, the assumption was that pike hunts prey differently in such conditions. Until then, it was thought that the pike catches prey that it sees or feels with the lateral line (an organ that fish have and which is similar to the human sense of touch). The assumption is that the pike hunts using smell. And that assumption of the English fishermen was correct. They put a piece (filet) of mackerel on the hook (instead of live fish). Mackerel is a sea fish with a very intense smell. The pike attacked the bait from the hook. Whole mackerel can be used for bait.

At the same time, it is recommended to hunt with one rod and to “move” the bait more often so that the bait acts on the pike’s lateral line. On slow-flowing waters, it has been established that pike can smell mackerel (bait) at a distance of 60 meters.
It is positive that mackerel can be bought in every food store throughout the year, so this hobby (fishing) is also possible in winter. Another condition is that there are pike in the water where the angler catches fish. And don’t forget, true sports fishermen always return the caught fish to the water.
