Water temperature are one of the factors that determines how fish behave. Water temperature is also one of the factors that determines where fish will locates themselves. Fish dont all live in the same water, and each species of fish has specific requirement regarding the temperature of the water in which they live.
If the temperature of the water is within the preferred temperature range for the species of fish living in the water, those fish will be active and hunt for food to sustain themselves. However, if the temperature of the water is outside of the preferred temperature for that species of fish, those fish will experience stress or become lethargic and may even die. Each species of fish prefer a different water temperature.
How Water Temperature Affects Fish
The preference change with each species of fish. For instance, trout prefer cold water and live best when the water temperature is between the low fifties. When the water temperature reaches the mid-sixties, trout will begin to experience stress due to a lack of oxygen in the water and will begin to seek out areas within the river or stream where the temperatures are more cooler.
Largemouth bass prefers warm water and are found to be most active in water temperatures between the seventies and eighties. Because largemouth bass prefer warmer water temperatures, they will be found in shallow area of the water with lily pads. Trout, on the other hand, will be found in shaded areas of the water or deep waters where the water temperature are cooler.
The changing seasons cause changes in the water temperatures, which directly affect the location of the fish in the water. In the winter, water temperatures in many areas of the United States range between the thirties and forties. Due to the low temperatures in the water, most fish species will exhibit slow behavior and live near the bottoms of the lakes or rivers in which they live.
Spring months leads to an increase in the water temperatures to the fifties and sixties in many areas. During spring months, most fish will begin to spawn in areas such as bass and pike. Summer months in most areas of the United States feature water temperature that reach the eighties in the shallows of lakes and rivers.
Due to the high temperatures in the water during the summer, cool water species begins to move away from the surface of the water. The thermocline is a specific layer of water in a lake that has a rapid change of temperature within that layer. The thermocline acts as a barrier to the movement of many fish species.
Within a stratified lake, the upper layer of the lake is warm water, while the lower layer is cold water. Therefore, fish that require warm water will not swim beneath the thermocline, while cold water fish will not swim above the thermocline. Instead, the majority of fish will swim near the thermocline, where there is a balance between temperature and food availability in the lake.
Thus, you can find fish more effective if you can locate the thermocline within the lake, and fish near that thermocline. Water temperature can affect the stress level of fish. During heat waves, the temperature of the lake increase, which stresses fish like bass and catfish.
During cold snaps, the temperature of the lake decreases, which stresses panfish. When fish are stressed out of the water temperature, they will eat less food. Therefore, it is important for fish hunter to monitor the water temperature within the lake using specific tools.
There are a variety of tools that can be used to monitor the water temperature within a lake. One tool is a probe thermometer, which measures the water temperature at various depth within the lake. A fish finder can also be used to find the thermocline within the lake.
Finally, there are mobile application that display maps of the lake and water temperature levels. Additionally, you should check the water temperature at the surface of the lake, as well as the water temperature at ten feet, thirty feet, and any other depths that you wish to monitor. By monitoring the water temperature at various depths within a lake, a fish hunter can find the specific water temperature that the fish that they are seeking to find and hunt for.
