Electrofishing is the most scientifically advanced method of analyzing fish populations in freshwater lakes. Electrofishing provides a fisheries biologist with an accurate and safe means to sample a fishery population. AES electrofishing boat is state of the art. On average, AES shocks over 80 lakes a year. All collected fish are sampled and released unharmed into the lake; however, undesirable species will be removed during the survey. All data is tabulated and presented in a report with recommendations for improvements.

Services Performed During Electrofishing Survey:

  • Collected fish are weighed and measured
  • Evaluation of predator to prey balance
  • Visual examination of fish for diseases
  • Total species abundance
  • Identification of any undesirable species
  • Collected largemouth bass will be weighed and measured to calculate relative weight
  • Removal of undesirable or over abundant species
  • Water quality analysis will be conducted for several important water quality parameters: Dissolved Oxygen, Alkalinity, Visibility, and pH
  • Site study conducted for the physical characteristics of the lake. This includes: aquatic weeds or algae presence, dam and outlet pipe integrity, fish habitat availability, maximum depth and average depth, accurate lake sizing using satellite imagery
  • A management report includes: methods, background and specific explanations of the results in written and tabulated/graph format, detailed management recommendations for supplemental stocking strategies, harvesting rates and sizes of over-abundant/competitive species, supplemental feeding recommendations, lime application and fertilization recommendations. Recommendations also include dam/outlet repair, fish habitat enhancement, aeration requirements, and/or aquatic weed control.

Services Available Upon Request

  • Age/Growth Study: The otolith (ear-bone) will be removed from an adequate sample size of fish to determine the age of the fish. The ages of the fish along with length and weights will be submitted to provide valuable insight into their growth rate and potential.
  • Necropsy: All fish will visually be observed for external parasites. In addition to this we will exam the guts of sacrificed fish for the presence or absence of parasite, intestinal worms, flukes, etc. If fish show poor body condition this may provide us some answers on the current condition of the fishery.
  • Fish Tagging: We will tag up to 50 bass with numbered tags to track growth of those fish. All data (tag number, weight and length) will be submitted in the report to monitor their growth.
