From a research perspective, the Mississippi River Basin serves as a major nursery for freshwater fish and provides a crucial habitat for swimming, spawning and migration. In addition, the elevated water level and temperature are suitable for over 25 species, some of which can be found in no other North American river.
The most common fish species to be found in the Mississippi River are the bass, catfish and sunfish. Bass is both a popular and abundant fish in the river, and there are multiple types that inhabit it: largemouth, smallmouth, spotted, rock and striped. The catfish is also in abundance, with the flathead and blue catfish being the top two contenders. Finally, the sunfish, of which there are 236 varieties, is highly sought after by anglers in the summer months.
Experts believe that the construction of the river has created several more favourable habitats for fish, which explains why the variances are so high. While the construction of levees and navigation locks has certainly destroyed some fish habitats, the number of areas suitable for species that enjoy current or backwaters has increased.
The Mississippi River still supports a remarkable diversity of fish. As such, passionate anglers travel from all over to take advantage of the river’s abundant natural resources and healthy fish populations. These anglers, in turn, also help to protect the fish from negative fishing practices, such as catch-and-release fishing, thereby protecting these unique species for generations to come.
Fishing Regulations
When fishing in the Mississippi, there are certain regulations to be aware of. It is important to know the regulations for both the state and the Mississippi River before starting any journey. Fisheries management programs have been developed to guard against overfishing, as well as protect current fish populations in the river. The Mississippi Department of Wildlife, Fisheries, and Parks (MDWFP) provides detailed regulation information on each fish species found in the Mississippi, including protection areas, size limits and season lengths.
It is also essential to know the number and type of fish that can be kept and the live bait regulations. It is important to bear in mind that the regulations vary depending on the area and fishers need to stay informed on existing changes. Further information regarding the regulations can be accessed from the MDWFP website.
Aquatic Invasive Species
In recent years, a variety of aquatic invasive species have invaded the Mississippi River. These are non-native animals and plants that often disrupt local ecosystems and compete with or prey on native species. They can also cause economic losses to fisheries, water supplies, and navigation channels.
The most common invasive species to be encountered in the river are the Round Goby, a small-bodied fish found primarily in Lake Erie and the St. Lawrence River. Other invasive species typically seen in the Mississippi include Asian carp, zebra mussels, and white perch.
The invasive species can have a significant impact on the native fish, out competing them and reducing fish numbers. Therefore, it’s important to take all necessary steps to reduce the spread and further introduction of these species into the Mississippi River.
Angling Etiquette
When fishing in the Mississippi River, anglers need to be mindful of the etiquette associated with the sport. Knowing the legal regulations is important, but understanding the unwritten rules is just as essential. Under The Mississippi Sportfishing Angler Matters, anglers should always follow the catch-and-release rule, use barbless hooks and be mindful of weather conditions and other potential hazards such as lightning and cold water.
Moreover, certain sections of the Mississippi River can become crowded, and thus it’s important to respect other fisherman’s space and never interfere with another fisherman’s line. By respecting the rules, anglers have the chance to take part in a classic fishing experience while helping to protect the species and keeping the Mississippi River beautiful.
Impact of Pollution
The health of the Mississippi River has a direct impact on all fish species found within it. As a result, pollution can heavily affect their population sizes and their feeding habits. Unregulated land use and industrial processes have caused high levels of chemical runoff, which can be incredibly harmful to fish. The most prominent effect of this runoff is oxygen depletion, which is caused by excessive exposure to nutrients that can lead to algal blooms and reduce dissolved oxygen levels.
In order to protect the fish of the Mississippi, scientists and conservationists are working hard to reduce the amount of pollutants and waste entering the river, as well as to protect the surrounding habitats. For example, the National Oceanic and Atmospheric Administration (NOAA) is actively addressing the pollutants caused by agricultural waste and other activities.
Financial Benefits of Fishing
Fishing plays an important role in the economy of the Mississippi river basin. It is estimated that recreational fishing in the state of Mississippi alone generates over $800 million in economic activity per year.
In total, the economic contributions of fishing to the Mississippi river basin amount to around $6.8 billion annually. This is mainly thanks to the vast array of angling possibilities present in the river, as well as its commercial fishing industry.
The wide variety of fish species that can be found in Mississippi, coupled with its long season, provides an invaluable boost to local businesses. The angling community is an important part of the economy and has a positive impact on both the environment and the livelihoods of riverside communities.
Conservation Efforts
The conservation efforts for the fish in the Mississippi are largely focused on angling regulations as well as habitat protection. From the National Oceanic and Atmospheric Administration (NOAA) to the Mississippi Department of Wildlife, many organisations are working hard to restore the river’s natural balance.
In addition to the efforts of these organisations, individuals can also make a difference by participating in river clean-ups and advocating for environmental protection. By removing pollutants and actively speaking out on issues such as water quality and conservation, any individual can help to ensure that the fish in the Mississippi River can thrive for generations to come.
Flow Management
Flow management in the Mississippi River is also vital in protecting its fish species. Flow management programs are designed to reduce the occurrence of flooding, while maintaining the river within its banks. They also achieve controlled water releases through the construction of dams, levees and other structures, when combined with stream gauges and other data collection methods.
In addition to controlling changes in water levels and flooding, the improved flow of water also helps to reduce the temperature and dissolve oxygen levels, making it a more suitable environment for fish populations. By taking a holistic approach to flow management, the Mississippi River can remain both a safe environment for fish as well as a recreational hotspot for years to come.
Impact of Water Diversion
Water diversion can have a significant impact on the fish of the Mississippi River. Water diversion projects are designed to take water from the river and funnel it into irrigation, public drinking water and other uses. This can limit the amount of water available to fish, making it more difficult for them to survive and reproduce.
In addition, water diversions can affect the temperature and water flow of regions of the river, making the environment unsuitable for certain species. Consequently, it is vital that any water diversion projects are designed with the environment in mind, to ensure that it remains conducive to the growth of fish populations while simultaneously meeting the needs of people.
