Fish Farming for Survival Protein, by J.D.

One of the requirements for long term survival is high quality protein. High on the list for many survivalists would be chicken eggs and rabbit meat. Of course one problem is having something available to feed the chickens or rabbits. I have been experimenting with another source that basically raises itself and is easily obtained. I am talking about fish. Here is a summary of my results after experimenting with my small pond:
In order to provide enough fish [with a "natural' (not food supplemented) pond], count on 1 acre of pond per adult and perhaps 1/2 acre per child. Of course if you supplement this with chicken eggs or other sources, you can get by with less.
To start, it is best to begin with a clean slate. This means contacting your local fish and wildlife department and having them poison your pond with a temporary poison. This will remove all undesirable trash fish that will compete with your production. This step is optional, and I was successful without resorting to this method by overstocking my forage fish.
Next, consider the food pyramid. What you are doing is creating an ecosystem. At the bottom of your food pyramid are phytoplankton and bacteria. In order to boost their production, you can add a small amount of fertilizer to the pond. In a post-TEOTWAWKI scenario, this can include chicken manure. If your pond is murky, then this step is probably unnecessary.
The next level of the pyramid is zooplankton. After some research, I discovered the daphnia, also known as the water flea. These little critters feed on bacteria, but they are also one of the few organisms that feed on one-cell algae. The best place I discovered to buy them is from Dallas Discus. Google on "Dallas Discus Daphnia" to find their web site. They will ship daphnia to you direct. I purchased the 3 species starter culture for around $25. Daphnia also have a great feature. When the water temperature drops, they will lay eggs that will survive the winter. During warmer months they reproduce by live birth and increase at a geometric rate. I found a sheltered area of my pond that had a lot of water plants to introduce the daphnia.
Next on the list is forage fish. I used two species, the fathead minnow and the blue gill bream. The fathead minnow will get clobbered if put directly in a pond, so I put mine in the creek that feeds it. A good portion stayed in the creek, but clouds of minnows would periodically swim into the pond.
For forage, it is hard to beat the blue gill. These fish will spawn multiple times per year and will also reach eating size. Be careful and order only “native blue gill”, “non-hybrid blue gill”, or “copper nose bluegill”. Do not order “hybrid blue gill” or “hybrid bream/sunfish”. These will grow quickly, but they do not reproduce well. The copper nose bluegill is actually a sub species, and not a hybrid. They are great for the pond, however they should only be used in warmer areas. Native blue gill can be used in most of the U.S. and are even a popular fish to catch ice fishing in Minnesota. Another cold water forage fish to consider is the yellow perch. I do not have much experience with them, and can not comment on their use. One fish to avoid, however, is the crappy.
The red ear bream or shell cracker is another species of forage to consider. They will reach eating size also, and they eat different foods then the blue gill, such as snails. These should only be used in more southern areas however.
Finally there is the apex predator. These are needed to keep the bream population healthy, and they provide a lot of meat. For my pond I chose the large mouth bass, though the channel catfish is another alternative.
Stocking Rates: For a healthy population, stock 1,000 bream per 100 bass, per acre. So a typical stocking rate would be 800 native blue gill, 200 red ear bream, and 100 largemouth bass. You should also stock 10 pounds of fat head minnows. Put a few pounds in any creek or stream that feeds your pond, a few pounds in the vegetation, and the rest in the open water. The native bass will hammer the open water minnows, which will allow your new bream to find safer waters.
Harvesting: For harvesting, use the same ratio. Remove 10 bream for each bass you catch. The bream are easily caught using a cricket or worm on a hook. To prepare, cut off their heads and gut them. Remove the scales. Fry whole. Bass are best prepared by filleting them. Both species are excellent to eat with a very mild flavor.
After you stock your pond, you are finished. You really don’t have to do anything else. However, I have been able to increase my production by feeding my bream. It is best to use a 30% protein floating catfish pellet to do this, though I have had great success using Wally World kitten chow with the same protein content. Post-TEOTWAWKI, you can increase production by raising earthworms and feeding these to the fish. I have not done this yet, but I will try using grass clippings to feed the earthworms. The composted grass and worm casing mixture should make for an excellent additive to a vegetable garden.
My next experiment for this season is to try preserving the fish. I have not done this yet, but from what I have read, I will soak the fish for thirty minutes in a brine solution and then cold smoke for 12 hours. This would make for a good winter food supply, though bluegill can be caught year round, even via ice fishing. I have friends who stored smoked fish using regular canning methods and ate it all winter long.
Preparing a fish pond is an excellent option for a retreat that you can not permanently live in, since if you stock using the correct ratio, the pond will stay in balance and take care of itself. Your protein supply will be waiting for you after the Schumer hits the fan. Remember to stash a large supply of fishing gear including hooks and monofilament line. Also, a pellet gun [could potentially be useful] for removing unwanted herons. Note that this is currently illegal, so follow your local, state, and federal laws. - J.D.

JWR Adds: In my estimation it is a far more efficient use of resources (especially time) to install protective netting over your fish ponds, rather than guarding them against predators. Osprey, herons, egrets, kingfishers, and cormorants are relentless. They will wait until the days that you are away from home and then clean out your pond. Unless your pond is quite large, the expense of constructing net supports and buying netting is far outweighed by the value of the extra fish that you will harvest. Fish farming is great way to provide self-sufficiency and it can be very profitable. "The Werewolf" (SurvivalBlog's correspondent in Brazil) is a fish farmer. He raises Tilapia. I know of one gent in Idaho that started out with one 20 foot diameter tank full of trout. He eventually added more and more tanks. He sells primarily to the restaurant market, shipping out the fish packed in boxes chilled with dry ice. His operation eventually grew so large that he and his family were spending several hours a day, seven days a week, just gutting fish. So he bought a $25,000 electric fish cleaning machine from Germany. You insert a whole fish head-first into the machine and it pops out the other end completely de-gutted and washed. That machine is quite a labor saver.
