Problem Statement
Many human-induced environmental factors such as habitat degradation, introduction of invasive species, and historic fishing pressures have lead to the decline of the lake sturgeon population within the Lake Champlain basin.

Goal/PurposeResearch and compile information about
lake sturgeon in the Lake Champlain watershed
Determine primary stressorsMake recommendations based on
gathered data
![Page 4: Reviving the Lake Sturgeon in the Lake Champlain Watershed Sarah Donelson Nick Costello Catriona Brosius Devon Snyder](https://reader036.vdocuments.us/reader036/viewer/2022062500/56649ec95503460f94bd6001/html5/thumbnails/4.jpg)
Objectives1.) Assess the feasibility of improving the lake
sturgeon stocking program in Lake Champlain
2.) Understand negative effects of predatory and competitive species on lake sturgeon
3.) Identify historical densities, locations, and uses of lake sturgeon
4.) Based on current and historical occurrence of lake sturgeon, understand how habitat loss has affected the Lake Champlain population

It is an ancient family of fish: having been around since the Upper Cretaceous period (136 million years ago)

Fishing History Early 1800:
sturgeon viewed as nuisance species
Mid-Late 1800: heavily fished
1900 – 1970: little known, other than that populations all over were declining

Life cycle Sexual maturity is reached at ages
14 to 33 for females, and ages 12 to 22 for males
Females spawn once every 4 to 9 years
Males spawn once every 2 to 7 years
Spawning occurs on clean, gravel shoals usually below the first large rapid or dam
Life span can reach around 55 years for males and 80 to 150 years for females

Habitat Loss
![Page 11: Reviving the Lake Sturgeon in the Lake Champlain Watershed Sarah Donelson Nick Costello Catriona Brosius Devon Snyder](https://reader036.vdocuments.us/reader036/viewer/2022062500/56649ec95503460f94bd6001/html5/thumbnails/11.jpg)
Requirements of Spawning Grounds
Temperature between 6.6˚ and 16˚ C
Water Depth between 2 and 15 Ft
Water Velocity between 1.6 and 3.5 Ft/Sec
Substrate consisting of mostly gravel and cobbles

Spawning ProcessSturgeon find appropriate spawning
grounds
Lay eggs which adhere to rocks
7 to 13 days later, eggs hatch
Fry drift for sometimes even a few kilometers before landing in spaces between rocks on the river bed

Dams
Sturgeon cannot jumpDams and Natural Waterfalls affect their ability
to find suitable spawning areas
Although they can swim over 1,000 kilometers, stream obstructions make this impossible

Stocking Issues
Introduction of new genetic strains
Healthier stocked populationsCompetition
Hybridization or Outbreeding Depression

Stocking Feasibility
Study conducted for Lake Champlain in 1994Natural reproduction would not be enoughSuggested stocking
A 1995 review group gathered to evaluate planSuggested a survey of current population be
conducted before stocking implementationStill collecting data in Vermont with no
stocking plan in place

New York Stocking Program

Limited data currently available

Recommendations
Continue monitoring and collecting data but at this point, do not stock in Lake Champlain
Lower concentrations of lampricide, use TFM-niclosamide
Removal of habitat obstacles
If eventually it is possible to stock with the native genome, then establish a stocking program
