Largemouth Bass Populations: What Affects Bass Fishing on Large Reservoirs

no-image

Anglers generally hold a passion for a particular species of fish and often it is tied to a specific fishery say for example the largemouth bass population on Kentucky Lake. Kentucky Lake is one of the most famous bass fishing destinations in the country, and those that live here have a special bond with the expansive fishery. That passion has led much of the tough fishing and what has happened to the largemouth bass population on the lake in the last few years to be misattributed to many different factors.

The lake is going to experience a rebound and the data is being used to not only predict but also explain what actually happens with a bass population on extensive and diverse fisheries when many ecological factors change.

This will serve as a longer narrative on what can actually hurt and help bass populations and dispel many of the common notions and conspiracy theories that really don’t affect large fisheries the way they affect smaller ponds.

Here are 8 common factors for focus that can affect or at times mistakenly get blamed for a decline in a largemouth bass populations:

  1. Over harvest
  2. Tournament pressure
  3. Carp influx (i.e. food competition)
  4. Lack of grass
  5. Water levels around the spawn
  6. Habitat
  7. Stocking
  8. Spawn Class Size and Abundance
