Fish lives at different depths within a body of water, and each species of fish choose specific depths within the water based off the temperature, oxygen, and light within that depth. A person who wish to find fish within a body of water must understand how deep the water is and how the fish species within that body of water chooses to stay within certain depths based upon the environment of that water. Water temperature influence the depth at which fish species remain within a body of water.
Warm water fish, like largemouth bass, remains in shallow waters in that area. Bass remains in shallow waters to find there food, and to maintain their high metabolism levels. Other fish species, like walleye and perch, remains in the middle depths of the water body.
Where Fish Live in the Water and How to Find Them
These species remains in these depths because the areas within those depths contains rocky shelves and light levels appropriately for there vision. Trout fish species remains in deep, cold waters. Trout remains in the thermocline, which is the layer of water in which the temperature drop the most within that body of water.
The temperature in the thermocline is usually around fifty-five degree Fahrenheit. The thermocline is important in that the thermocline influence the amount of oxygen that is within the water. The water at the surface of many water bodies can reach warm temperatures, trapping the oxygen in certain area of that body of water.
The depths beneath the thermocline can contain very little oxygen. Predators stays just above the thermocline in the water because of the amount of oxygen in that depth of the water. A person can use electronic fish finder to map the depth of the thermocline within the water.
These electronic fish finders map the thermocline as a line in the water. If a person ignores the thermocline, the person may find there bait in empty area of the water. Some fish species can handle depths more better than other fish species.
For instance, you can find bass in both shallow and mid-depth waters. Smallmouth bass prefer rocky area, while largemouth bass prefers areas with abundant weeds. Pike and muskies prefers both shallow and mid-depth waters.
Trout can be found in depths that are very deep in the water. Deep water trout may remain at depths of more than one hundred feet. Panfish, like bluegill and crappie fish, stay in groups or school around areas with brush cover in consistent depths.
Seasons change the depth where fish stays. During spring, fish heads toward shallow waters to spawn as the water becomes warm. During summer, fish seeks the edges of the thermocline.
In the fall, the lake water mix together which causes the dissolved oxygen to move to different level in the water, thus forcing the fish to head towards shallow waters again. During winter, deep basin in the lake attract the fish due to the stable water temperatures. Fish also seek shallow waters at dawn and at dusk to feed, but head to deeper area of the lake in the middle of the day.
Dissolved oxygen is necessary for fish to survive. The surface water in lakes contains alot of dissolved oxygen due to the mixing caused by the wind and water waves. However, water deeper than fifty feet contain very little dissolved oxygen thus most fish cant survive in deep water alone.
Some of the exception include burbot. Depending on how deep the fish are, a person must choose the correct fishing technique. If a person wants to find trout, they can wade into the shallow waters and use nymphs.
If a person wants to find crappie, they can use minnows to float over the weed. To find bass, people can use jigs to cast on the breaklines. For lake trout people can troll with weights to attract the fish.
Thus, the fishing technique that a person uses must be correlated to the depth and cover of the water in which they are fishing. Fish have a natural instinct to move in response to gradients and currents in the water caused by the wind and the clarity of the water. For instance, windy days pushes fish toward the shore, while clear water allow the fish to seek deeper waters.
A person can use electronics to find fish in the water. However, using these device requires an understanding of the movement of the fish. If shallow waters in a lake do not contain any fish, then a person can move there fishing bait to deeper waters since the fish are located in specific layer of the lake.
