So the first thing you need to do is figure out to whom you will sell your tilapia and how you will let them know. We recommend that you hold off on hatching your own tilapia fingerlings until after you find out who your customers are and what they actually want.
Remember that the demand for your products will be based on the needs of the people to whom your advertising reaches, and may not be what you initially anticipated. Setting up for the wrong species can be a ten-thousand-dollar mistake. Trust us, we've been there. You should start off by buying one hundred pure strain mixed-sex Blue tilapia fingerlings, one hundred predominantly-male Wami hybrid tilapia fingerlings, and one hundred pure strain mixed-sex Nile tilapia fingerlings.
Put them into three 55 gallon aquariums, and get yourself familiar with the day-to-day responsibilities while you attempt to sell them. Before long, you will be able to identify the males from the females in the mixed sex tanks, and you can use them as the basis to make your own breeding colonies.
By the end of your first year, you will know everything that you need to know about the demand for your fingerlings, and your ability to sell them. We do not recommend, however, that you invest your efforts into procuring breeding sets to produce either of these males. A breeding pair to produce the Sipe's Hornorum Wami cannot be purchased without the consent of Mike Sipe himself, and genetically modified Nile males with YY chromosome pairs are lab produced in Europe, and protected by international patents.
While it is true that you might pay a little bit more per male than we do, you don't have to buy or import hundreds at a time as we do. Fair Warning: We are responsible for helping to establish much of our own retail competition. Because most of our tilapia fingerlings are headed for commercial and institutional operations.
These types of customers are typically under contractual obligations or funded by grants and can't be easily "taken" due to the planning or red tape involved. Internet sales of tilapia fingerlings to private individuals accounts for around thousand fish per year.
By the time you factor in all of the re-sellers, accidental breeders, and aquaponic opportunists, setting up websites and buying pay-to-click ads, the Internet competition feels like a bunch of wolves fighting over a hummingbird.
We strongly urge you to find a place to sell your fingerlings away from the Internet if you want to make a career out of it. I don't want to sell my fish to anyone. One of the great things about tilapia farming at home for your own personal use, is the absolute sense of independence and freedom that it provides.
Because you aren't selling your tilapia, there is no FDA involvement. You won't need a fish dealers license if your state requires one to sell tilapia, and you won't need a business license either. In fact, you won't even have to set up a business, do any accounting, or pay any taxes. Another nice thing about raising and processing tilapia for your own personal use is that you can plan your growing season and harvest date just as you would with any garden crop.
This can be accomplished by keeping a breeding colony in separate aquariums for the male and the females until you are ready for them to spawn. In our area, January is about right. As soon as you can economically keep the water temperature warm enough, you can move the fingerlings into your pond. For us, this doesn't happen until about April or May, but everyone has their own microclimate so you'll have to be the judge.
Remember, tilapia convert a higher percentage of food into weight during their first days of their life. After that, they grow much slower and the amount of food eaten to weight gained goes up considerably.
By starting out with a pure strain food grade Blue tilapia or a Wami hybrid, you will achieve the highest weight gain for the lowest food, electricity, and maintenance costs. Critical Point: It costs an average of. It will cost about. Don't be lured into saving a few cents on fingerlings today, then lose your savings later in higher costs.
Only buy food grade whenever you can. By the way, tilapia older than 18 months are a bit too gamey for our taste buds, which is why we didn't go out any further with our cost example. If your aspirations fall more on the survivalist side and you don't want to be dependent on Purina for your fish food, you can feed your tilapia duckweed Lemna minor instead.
Remember that while all tilapia are considered omnivores because of their ability to thrive on a wide variety of food, in nature, tilapia are primarily herbivores. Their jaws and teeth are specifically designed to scrape algae from rocks and grind aquatic plants. If you can grow it in sufficient quantity, duckweed is all that your tilapia will need from fingerling to harvest size. For tilapia fry, you can grow algae by putting an aquarium in a sunlit window and then scraping off what you need to feed your fry.
We recommend that you focus your home tilapia farm on the production of food grade pure strain Blue tilapia for all the reasons mentioned in the previous sections.
If you happen to be one of the unlucky few who lives in a state that doesn't allow Blue tilapia, then we recommend that you choose natural Wami hybrids, for their rapid growth, as your second choice. If you want to raise your own tilapia from eggs, you will need to purchase a breeding colony. A breeding colony is capable of producing thousands of offspring over several years.
Of course, if they are making too many babies for you to keep up with, you can always separate them. I don't want to eat them. For pond owners who wish to avoid the use of herbicides in their ponds, nothing can beat the appetite of a pond grade Blue tilapia. These special tilapia are separated out during the fingerling grading process due to their small size, and subsequent slow growth rate. Here's a quick explanation of why they are so unique.
They prefer to graze very close to the shore where the water is shallow, and they are relatively safe from the predators of deeper waters. As luck would have it, this is also where most of the algae in a pond is produced, due to an abundance of sunlight. As the tilapia grow into fingerlings, they add small aquatic plants to their diet, such as duckweed.
By the time that they are a couple of months old, their daily weight gain stays pretty constant of the next six months. Unfortunately for the pond owner, after a tilapia reaches adulthood, it is far more interested in larger aquatic plants than it is in algae. Enter the pond grade Blue tilapia. Once upon a time, these tilapia were destroyed as inferior by tilapia hatcheries.
A pond grade blue tilapia grows very slowly. So slow in fact, that it may never grow larger than eight inches. Even if it does, their older age to harvest gives them a river bottom taste that most people find hard to swallow. Fortunately for these little fish, pond owners discovered a job of them that's perfectly suited for their unique physiology.
As a pond cleaner, they are perfect. Instead of eventually growing to a point where they ignore shoreline algae for deeper water grazing, these remain small and continue to graze on a combination of algae and duckweed. In areas where ponds freeze in winter, the lower cost of pond grade blue tilapia makes restocking them in the spring a worthwhile enterprise.
I may eat one from time to time, but I am more focused on my plants. The whole idea of aquaponics is harmony, balance, and being good stewards for the environment. Yet every day, people toss random handfuls of unsorted blue or nile tilapia of questionable origin into their systems, and then hope for the best.
The problem goes back to aquaponics dealers and educators who tend to be very plant-centric, and view tilapia as nothing more than another system component. People who build DIY aquaponics systems out of IBC totes, usually only set aside one tote for their tilapia; which means that they are typically only going to raise about 75 fish at a time.
Compared to their expected vegetable crop output, a mere 35 pounds of finished tilapia filets just isn't that exciting. Another problem has to do with the marriage of hydroponic and aquaculture systems in general. As you undoubtedly know, aquaponics is really nothing more than water from an aquaculture fish system flowing through a hydroponic plant system. As separate systems, each is set up to perfectly support the life that they hold. However, when they are combined, a compromise must be found that both sides can live with.
Take pH for example. Tilapia thrive best in a pH of 8. In an aquaponic system, a trade off is made that both the plants and the fish can work with. The compromise is idea for neither, and as a result, neither will achieve the performance results of their separated systems, however both will survive and do well.
To prove the point about aquaponics educators being plant-centric, many course materials have aquaponic growers set their pH to exactly match the needs of the plants, or incorporate composting worms, without any regard to the "comfort" of the tilapia. The whole attitude seems to be: "let the tilapia tough it out So the common sense question is: Why even bother with the tilapia in the first place?
After all, fertilizer solutions for hydroponic systems are far cheaper than tilapia, and hydroponics requires a lot less maintenance. The truth is, it all goes back to harmony, balance, and stewardship of the environment. Done right, aquaponics is a near-perfect growing method.
Of course, our version of "done right" is an actual balance that isn't one-sided in favor of the plants. When people select plants for their aquaponic systems, they do their research. They read about how fast their plants will grow and how good they will taste.
They don't limit themselves to the lowest price. They understand that the lowest price usually means inferior seeds. They only buy their seeds from a reputable supplier that has great customer service and never-ending free advice, online and offline.
It kind of makes you wonder why many of these same people are so willing to carelessly buy random handfuls of tilapia fingerlings from re-sellers websites with nothing more to offer than places to spend their money.
When it comes to selecting tilapia fingerlings for aquaponic systems, there are only two rules that should be followed:. The tilapia in an aquaponic system are already in less-than-ideal conditions in general. As individuals, they have slight physiological differences within their own species as well. In other words, even in an aquaponics system where only one species exists, every tilapia is experiencing the environmental conditions in its own unique way. Sort of how some people have allergies, or are always cold, or react differently to stressful situations.
Tilapia also exhibit different behaviors such as aggression, or dominance, or submission. Most tilapia swim in social schools, however some individuals keep to the edges of the group, or outside of it entirely. When species are mixed, the number of stressed individuals increases to a point where their immune systems can be compromised, and random deaths will begin to occur.
Lowered immune systems can also result in parasitic outbreaks, or even a pathogen, which can wipe out an entire aquaponic system, including the grow beds. As far as putting ungraded, or mixed grade fingerlings in an aquaponic system is concerned, we have an entire page that explains fingerling grading in great detail.
We urge you to educate yourself about fingerling grading before putting any tilapia into your aquaponic system. Provided that you follow the above two guidelines, just about any species or grade will work in an aquaponic system.
The only grade to avoid should be pond grade, due to the fact that there will be no possibility of food return on the tilapia investment. Call Lakeway Tilapia at today! Live Tilapia Selection Guide Which is the right live tilapia species for you? How to use this guide. Hold on just one flippin' minute!
I am an aquaponic farmer. These conditions include: A safe, relatively flat surface, for the female to lay her eggs, then scoop them into her mouth, before they are eaten by the other tilapia.
A location that the male can defend, while the female deposits her eggs to be fertilized. After the male quickly releases his sperm, he goes back to defending the spot while the female gathers the eggs back into her mouth. This process is repeated several times until the eggs are fertilized. Each time, the male must fight back other fish determined to eat the eggs.
The following are noteworthy for having the best characteristics, including their rapid growth rate, among the many varieties of tilapia used in fish culture and other recirculating systems:. Nile Tilapia Tilapia Oreochromis niloticus Tilapia 2. Mozambique Oreochromis mossambicus In this article, we will address some of the variables that influence the growth rate of tilapia, the difference between growing mono-sex and mixed-sex tilapia, and the fastest growing tilapia breeds.
Because of its different strains, it is also difficult to identify which species grows the fastest. There are, however, a range of factors that usually affect fish growth rates, primarily environmental and management factors. This involve the supply of food and oxygen, water temperature, storage, and water quality. Before looking into what breed of tilapia grows the fastest, it is important to understand all these factors. Availability of food and oxygen Two of the most important factors that dramatically contribute to the growth rate of tilapia are food and oxygen.
As tilapia is primarily herbivorous, it will quickly help them achieve their mature size by feeding them a sufficient amount of plant-based food.
Below is a detailed description of each breed. Nile tilapia is a favorite of fish culture beginners because it is relatively easy to grow. It is believed to have been used for farming 3, years ago because it is a frequent subject of paintings in the tomb of a wealthy Egyptian. They can now be found in some areas of the United States with warm temperatures, although they are primarily farmed in Asia.
Among all the other tilapia breeds, it is considered to have the fastest growth rate because it grows roughly 1 to 2 pounds in 7 months. It also thrives in varying environmental conditions and water quality. The ideal pH for this breed is 5. The Mozambique tilapia is a native of Africa introduced to the United States for aquatic plant control.
It is usually olive-gray with a yellow belly, and unlike Nile tilapia, it cannot withstand cold temperatures. The growth rate of Mozambique is 2 pounds in one year. This breed should be fed 3 to 5 times a day for faster growth.
Also, the ideal pH range for this fish is between 5 and 9. Tilapia is a favorite fish to raise in pond and tank culture because of its fast growth rate. According to what we have discussed above, some of the factors affecting its growth are food and oxygen availability, water temperature, stocking, and water quality. Since tilapia also produce a lot of offspring, learning about their growth in mono-sex culture and mixed-sex culture will also help practitioners understand the relationship between stocking density and growth.
In terms of which tilapia breed grows the fastest, Nile and Mozambique topped our list. The Campbells love finding sustainable and fun ways to increase their independence from traditional brick and motor supermarkets. Aquaponics provides a full lifecycle food source for families and a great hobby. Koi are hardy fish that can withstand various water temperatures.
Still, poor water conditions may cause…. Koi fish can thrive on…. Among the several varieties of tilapia being used in fish culture and other recirculating systems, the following are notable for having the best characteristics, including their fast growth rate: Nile Tilapia Oreochromis niloticus Mozambique Tilapia Oreochromis mossambicus In this article, we will discuss some of the factors that affect the tilapia growth rate, the difference between growing mono-sex and mixed-sex tilapia, and the tilapia breeds that grow the fastest.
Factors affecting the tilapia growth rate The growth rate of fish varies from species to species.
