Lake Nipissing Walleye Fishing – Restocking

For over 18 years the Lake Nipissing South Shore Association supported by the Ministry of Natural Resources has been running a Walleye Restocking Program to help maintain a healthy fish population in our beautiful lake. Each year volunteers put in hundreds of work hours to make sure future generations will be able to enjoy fishing Lake Nipissing.Studies show that the survival rate in a natural spawn is about 3 – 4 % while restocking in a properly run hatchery has a success rate of over 85 %!

Mobile Walleye Hatchery

In 2001 / 2002 a new mobile hatchery was built to replace the old but still good working facility. It will allow us to run the hatchery wherever the circumstances (water supply etc.) are best for a particular year and even to take it on the road to schools and other interested groups. Education is one of the main concerns to make this and other similar programs work.


Mobile Hatchery

Step 1 – Catching Walleye in Lake Nipissing

In spring when the Walleye spawn our work begins: We catch the fish in nets that will allow us to release it healthy and unharmed after milking them.

Step 2 – Milk Walleye

Male and female Walleye are brought to shore in live wells and milked to collect and fertilize up to 1 million eggs

Milking the fish is a very delicate job and demands a lot of concentration and attention or the fish could easily be harmed.

Step 3 – Fertilize Eggs

Once the eggs and sperm are collected they are mixed. By using a birds feather and stirring them gently we make sure all the eggs get fertilized without being damaged.

Step 4 – Add Tanic Acid

The eggs are hardened when circulating in a basket of fresh lake water. Using tannic acid we prevent them from sticking toghether, then they are brought to the hatchery.

Step 5 – Place Eggs in Jars until They Hatch

The eggs are now put in jars until they hatch. This will take between 17 and 35 days. Our hatchery holds up to 2 million eggs.

Step 6 – Release Fry Into Special Ponds

Once the fish hatch they are called fry.

In previous years these baby Walleye have been released into special ponds to grow to about 1 1/2 inches in size. Then the fingerlings were released into the lake.

Step 7 – Release Walleye into Lake Nipissing

In 2001 and 2002 some of the fish was released into the lake as fry. A MNR study will show if this will improve the survival rate of the baby fish. The same study will also try to find out if the Walleye returns to the spot where it was released to spawn in years to come.

Step 8 – Clean Hatchery and Prepare for Another Year

Cleaning and maintaining the hatchery and ponds conclude the work until winter comes and the lake freezes. It is during the cold months of the year that we do another job: by putting rock piles on the ice that will sink to the bottom once the ice melts we create new spawning beds for the Walleye’s natural spawn.


We work with nature – come and join us|: please support the Walleye Restocking Program, catch and release and use our natural resources responsibly

We want to thank everybody involved for the time and effort they put into this great cause. Without all the volunteers it would be impossible to do all the work!

    I am not familiar with Lake Nippising but I have fheisd in Canada numerous times. Here is what I’ve found- Most Border and Canadian Lakes can be easily fheisd with only a handful of various bait’s and lures. Bait’s?- Leeches and Shiners will be your best bait for Walleye, Smallmouth Bass, medium-sized Northern Pike. If you are dead-set on catching trophy Pike with bait an 8-12 Sucker would be your best bait. Lures?- Jigs are probably the cheapest and most productive lure. 1/4-3/8 OZ being the best weight’s and Black Chartreuse being the better colors. Berkley Gulp Leeches and 4 Curly-tailed Grubs are good trailers for your jigs. Jigs are also perfect tipped with a live minnow or leech. Spoons can be fantastic for Northern Pike/Musky. Rapala’s can be productive in the shallower sections of any Canadian lake. Any Rapala that resembles Cisco’s, Shiners, or Shad can be deadly if trolled behind the boat. It’s important to use Fluorocarbon leaders or a low diameter Braided line in some clear Canadian lakes because of the amazing clarity of the water. I’ve used Fireline 4/10 smoke-colored braid and Power Pro 3/8 braid with very good results. Dog -walked Topwater lures can be esp deadly on Smallmouth Bass and Northern Pike. Try to find current or a stream flowing into your lake. This will increase your odds of catching fish. Remember, it’s not unusual to catch 50-100 fish in one day in Canada! Hope this info helped ya? Good fishing. Was this answer helpful?
