Your Sponsorship Will Help Ensure Conservation Officers Have a Proven, Selective, Safe, and Low-Cost Method for Controlling the Asian Carp Population.

Environmental Threats


Murky Waters

The Bighead, Silver, and Common carps invaded Lake Yankton in a 2011 flood. By 2014, they comprised over 90% of the fish bio-mass.

Water visibility decreased from 7+ feet to under a foot and all of the game fish were gone.

The Asian Carp problem became so prolific that officials decided to kill ALL the fish with the highly toxic Rotenone, and then drained the entire lake.

It took several years and millions of dollars to restore Lake Yankton.

Pushing Out Native Fish

Bighead and Silver Carp can grow over 6 inches in the first year, ceasing to be prey for most native game fish. As the Asian carp fish bio-mass increases, the population of native filter feeding fish like gizzard shad and paddlefish decreases. The native game fish (like bass) are threatened, too, as their food source disappears.

Changing the Composition of Plankton- The Building Block of Life

Plankton are floating organisms including (but not limited to) algae, bacteria, immature animals and protozoa. Plankton is the basis of marine animal life.

Asian Carp quickly out-compete native filter feeding fish for this food source. They are voracious filter-feeders that eat smaller plankton than most native filter feeding fish, causing a severe shortage in the food supply.

These carps’ digestion are inefficient and are always excreting. The excrement will change clear water green. The bighead and silver carp will concentrate toxic bluegreen algae, harmful algae blooms.

Strong Migration Instinct

Asian Carp escaped from fisheries in Arkansas during a flood in 1980. The Fish now inhabit 6,400 river-miles throughout the Mississippi Basin

Their territory grows every year. The bighead and silver carp move freely throughout the Mississippi Basin, crossing locks and traveling hundreds of miles a season.

Threatening A Way of Life for Boaters & Fishers

Concussions, Broken Bones, and Bruising

Getting hit with a 20 lb. Flying Asian Carp is no joke, especially if youre in a boat going 20-30 mph. there have been reports of concussions, broken bones, cuts, and significant bruising.

Ruining Fishing

Best case: Native game fish are severely endangered and their population drops significantly. In the worst cases, like Lake Yankton, they completely disappear.

What’s Being Done Now

The Federal Government is Spending about 53 Million Tax Dollars Every Year On the Following Measures:

1. Barriers

The Asian carp migration is slowed down by natural and manmade barriers. Examples are waterfalls, dams, or electric currents. Some barriers cost $200 Million to build. They are somewhat effective, expensive, and serve as a passive defense and they don’t do much to counter the problem

2. Enforcement, Education & Early Detection

The public’s help is needed to control the bighead and silver carp. In an effort to combat the invasion, conservation officers monitor uninfested rivers and lakes for the presence of asian carp using eDNA tests. They ask that any caught Asian Carp be destroyed on site.

It’s illegal to own live asian carp in most states.

3. Population Control

Harvesting (net fishing) is the only population control used. Here’s the limitations of harvesting:

– Fish avoid people, nets and electricity.

– At best only 25% of the Asian carp infested 6,400 river miles are intermediately harvested.

– Harvesting a 50 mile stretch of river costs $1+ million/ year. It took 7 years of harvesting to significantly reduce the Asian Carp population.

A lower-cost method is needed to reduce all life stages in
all 6,400 river miles if we are to control the Asian carp population.

A Proposed Solution

Pesticides must be an integral part of reducing and controling the population of Asian Carp.

What Is a Pesticide?

The Definition:

A pesticide is defined as “any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any pest.”

Pesticides are regulated by the EPA.

Are All Pesticides Dangerous?

Not all pesticides are dangerous. Table salt is an EPA registered pesticide, and so is capsaicin- an active component in chili peppers.

The Ideal Pesticide

An ideal pesticide is safe to handle, affects only the target species, and then degrades in the environment to safe chemicals already present.


MJSTI is a Kansas City Startup that has spent 3 years developing a proven safe, selective, and low cost pesticide for Asian Carp.

The MJSTI Solution

1. Selective

The formulation is selective since it is a digestive poison. Only the fish that eat like the Asian Carp should be affected. In contrast, an inhalation toxin like rotenone kills all the gill breathing animals.
Conservation officers should be able to increase the selectivity by choice of bait and habitat.

2. Safe

The ingredients are FDA approved materials. Since the outside of the formulation is vegetable fat, it is safe to handle. If the Asian carp do not eat the bead or bio-bullet it will sink to bottom of the river or lake and decompose to safe levels of chemicals already found in our rivers and lakes.

3. Low Cost

The estimated raw material cost is 1/12 to 1/30 the raw material cost of the United States Geological Survey (USGS) Antimycin A/ beeswax bead. The raw materials are either EPA registered pesticides or approved inert materials with well-known and public toxicity studies. This should allow for a fast and low cost EPA registration of the formulation.

We Need Your Help!

We have developed a solution that can help fight back against the Asian Carp invasion. We need funds to commercialize it. You can make a difference. You can help protect our river systems. Please consider making a contribution!

Be Part Of The Solution.

There are over 20 million people (fishers, boaters, paddlers) directly affected by the Asian Carp invasion. MJSTI has spent over $40,000 and 3 man years to prove the formulation of its pesticide.

We have applied for grants, and will continue to do so. We seek investors and donors. Without funding, the testing and commercialization of our solution will cease. Your contribution can make a difference.
