Largemouth Bass are the prized fighters of North American freshwater, but even the mightiest can fall. Learn about the causes of death and the fascinating fate that befalls them after they die. Anglers and conservationists, this is one read you don’t want to miss! How and why do bass die … read on to find out!

How And Why Do Bass Die?

Quick Answer

Largemouth Bass can die due to a variety of reasons such as natural causes, disease, habitat loss, pollution, and improper handling. They can also suffer from oxygen depletion if they are kept out of the water for too long, such as when taking pictures. Once a Largemouth Bass dies, its body sinks to the bottom of the water and becomes a food source for scavengers, returning nutrients to the ecosystem.

Reasons for largemouth bass mortality

Largemouth Bass are a popular game fish in North America, known for their size and strength. Unfortunately, like all living creatures, they are not invincible, and various factors can lead to their death.

Top 5 causes that kill bass
  1. Hook injuries. Improperly removing a hook from a Largemouth Bass can cause internal injuries that may lead to death. Leaving hooks in the fish can cause fatal infections or damage their internal organs.
  2. Oxygen depletion. Largemouth Bass require oxygen-rich water to survive. When water temperatures rise or oxygen levels drop, they may become stressed or suffocate. In shallow, stagnant water, oxygen levels can drop to lethal levels, causing mass die-offs. Keeping fish out of the water too long for taking pictures causes stress and oxygen depletion. This can lead to fatal consequences.
  3. Disease and parasites. Largemouth Bass can be vulnerable to a variety of diseases and parasites that can weaken or kill them. These can include bacterial infections, fungal diseases, and parasitic infestations.
  4. Environmental stressors. Changes in water temperature, pH values, and pollution can all stress Largemouth Bass, making them more susceptible to disease and death. High water temperatures can increase metabolic rates, leading to oxygen depletion and death. Changes in pH can affect the fish’s ability to maintain proper bodily functions, leading to organ failure and death. Pollution can cause a range of health problems in Largemouth Bass, including reproductive failure, reduced growth rates, and mortality.
  5. Improper catch and release practices. Improper catch and release practices, such as using the wrong type of hook or releasing fish back into the water too quickly or too slowly, can increase the mortality rate of Largemouth Bass. If a fish is hooked deeply, it is often better to cut the line and leave the hook in rather than causing further injury. Fish that are released too quickly can experience trauma or shock, while fish that are held out of the water for too long for taking pictures can suffocate or become more vulnerable to predation.

The Circle of Life: What happens when bass die

When a Largemouth Bass dies, its body will sink to the bottom of the water, where it can provide nutrients for scavengers and other organisms. As the body decomposes, it releases nutrients into the water that can be taken up by plants and other aquatic organisms. This process of decomposition is an essential part of the aquatic food web and nutrient cycle, as it allows for the recycling of organic matter and the transfer of energy from one organism to another.

Scavengers like crayfish, turtles, and other fish will feed on the carcass of the Largemouth Bass. They break down the body and reducing it to smaller pieces. Bacteria and other microorganisms will also play a crucial role in the decomposition process, breaking down the organic matter and releasing nutrients into the water.

Over time, the body of the Largemouth Bass will decompose completely, returning its nutrients to the ecosystem. These nutrients are taken up by plants, which can be eaten by herbivorous fish and other organisms. In this way, the Largemouth Bass, even in death, continues to play an important role in the ecosystem, providing nutrients that support the growth and survival of other organisms.

3 Facts about Bass Mortality

  1. Largemouth bass can die due to hook injuries and mishandling during catch-and-release.
  2. Low oxygen levels in the water can lead to suffocation and death of largemouth bass.
  3. Natural predators, diseases, and pollution can also cause mortality in largemouth bass.

Summary

Largemouth Bass can be vulnerable to various factors that can lead to their death. Proper handling techniques when fishing and being mindful of environmental stressors can help prevent unnecessary mortality. Improper catch & release practices and keeping fish out of the water for too long for pictures can also increase the mortality rate.

When a Largemouth Bass does die, its body becomes an important part of the ecosystem, providing nutrients for other organisms. Understanding the causes of death and what happens after death is essential for conservation and management efforts to maintain healthy populations.
