MARION Reservoir Rough Fish removal Study
Rough Fish Removal at Marion Reservoir Final
Report
Over 551,155 pounds were removed between 2008-2010
Results:
Body condition of sportfish increased
Numbers of young gizzard shad increased
Severity of Blue green algae blooms decreasedSlide5
MARION Reservoir Rough Fish removal Study
Recommendations from studyCONTINUE PERIODIC REMOVAL OF ROUGH FISH AT MARION AND EXPAND EFFORTS TO OTHER LAKES WITH
h.a.b
. ISSUES
Modify removal efforts to include fishing during the spawn and use gear that will capture all sizes of carp (few small carp were removed during the study)
Consider technological advances such as
pheromoneS
and
autocidal
technology to reduce future spawning successSlide6
Same Sex aquaculture Production
Currently most rainbow trout stocked in Kansas are female
All female production uses testosterone for sex reversal of broodstock
Sex reversed females are then crossed with normal females to create all female (XX) offspring for stocking
Female trout grow faster and attain a larger size
A similar technique can be used to create “YY” males of any species using estrogen for sex reversal Slide7
New Autocidal Technique
YY TroJan Males
Produce and Regularly stock Trojan males (no “X” chromosome)
skew the population
towards 100%
males
Integrate with removal efforts
theoretically
resulting in wild population extirpationSlide8
Idaho research effort
developed two genetic sex markers
for Brook
Trout
employed juvenile sex reversal
methods using estradiol
Produced YY males for release into the wild
YY males spawn with wild females to produce all male offspring

currently developing YY common carp broodstockOver time the target species can be eradicatedSlide9Slide10
Trojan Male Technology
The Association of fish and wildlife agencies are voting this summer to allow use of federal SFR $ to fund a nationwide Trojan male undertaking to control a variety of aquatic invasive species
Kansas will join a partnership on common carp and possibly Asian carp efforts
Trojan male efforts need to be combined with removal efforts in an integrated pest management approach.
The dream of eradicating invasive species seems more possible than ever before
The Trojan males are not genetically modified organisms
No fish exposed to estradiol are released into the wild (they are hatchery broodstock kept on site)Slide11
Harmful Algal Blooms and Fishes
KDWPT will continue to utilize commercial fishing as a management tool
The state should consider continued subsidies for carp removal
Autocidal
techniques should be pursued to control invasive species contributing to
