Tilapia Temperature Requirements For Aquaponics

Last Updated on October 30, 2022 by Cinthia

Tilapia is the most famous loving fish among aquaponics farmers. They are pretty forgiving when it comes to adaptation generally. However, the tilapia temperature requirements are quite demanding because they are temperature sensitive.

Tilapia is a warm water fish. When it comes to using tilapia for your aquaponics setup, it is important for you to be aware of tilapia temperature requirements for aquaponics. This way, you will enjoy an amazing growth of tilapia, a good production rate, and a smooth aquaponics system.

In this post, we will be exploring tilapia temperature requirements so read on to learn.

Firstly, you should know tilapia fish is a very tolerant fish. They can adapt to a poor or substandard water quality environment. They are not food selective and they can feed on nearly anything edible.  But they are pretty delicate when it comes to temperature.

The most appropriate tilapia temperature requirements range from 75 degrees Fahrenheit to 86 degrees Fahrenheit.

Most tilapia fish are temperature sensitive and if the water temperature in your aquaponics drops to 68 degrees Fahrenheit, tilapia will be stressed and the growth of your tilapia fish will depreciate. Now, if the temperature drops below 50 degrees Fahrenheit, your tilapia fish metabolism will be super slow and the survival rate may be pretty low.

If they now fall below 40 or even 30 degrees Fahrenheit that will be a terrible time for your tilapia fish and they will most likely die.

The stress caused by temperatures below 50 degrees Fahrenheit causes deprivation to diseases resistance thus exposing or leading to tilapia infection caused by fungi, bacteria, and other pathogens.

Therefore, ensure you always keep your water aquaponics system in the right temperature range for your tilapia fish.

Tilapia fish originated from Africa or tropical regions as such have warm temperature requirements. Therefore, in other regions that are cooler especially in winter, you must adjust the tilapia fish environment temperature to suits their requirements.

Dealing with Tilapia in Colder Region

For all year round tilapia fish aquaponics system, recirculatory indoor systems are ideal. This is because the construction of the system can be insulated to preserve optimal heat for your tilapia fish. The heated water is as well conserved throughout the recirculatory system.

You can as well introduce an emergency heating just in case the climate snaps and meets you by surprise and you are unavailable or not close by. I’m sure you wouldn’t want to let your amazing aquaculture set up you have nurtured for a good period go down the lane by just a snap of climatic change, would you?

However, if you do not wish to spend too much money on heat, you can simply opt for the breed of tilapia fish that can tolerate cold or simply go for trout fish.

Tilapia Water Temperature Adaptation with Cold Water

It’s not uncommon to see tilapia fish adapt to their environment being that they are quite forgiving. There are various species of tilapia fish. From generation to generation, they might adapt and withstand temperature changes over time.

There are some tilapia breeds that have shown good tolerance to temperature changes. An example of cold-hardy tilapia species is the blue tilapia (Oreochromis aureus) and. The blue tilapia can do well from 45 degrees Fahrenheit. Therefore, we recommend you opt for this type of species if you wish to raise tilapia in a cooler region.

Nonetheless, when kicking off with raising your tilapia fish, especially the ones that were mailed or given to you by anyone – ensure you maintain a warm temperature of at least 60 degrees Fahrenheit.

What temperature does tilapia need to grow?

Depends on how old they are. If they're a year old or more, you should be fine with a slightly warmer tank. However, if they're only a few months old, you'll want to be careful and keep the water at around 80-85F (27-29C).
An adult tilapia will eat food every 2-3 hours. Tilapia are a long-living fish, but not as long-lived as other species. Their lifespan is estimated at up to 15 years in captivity. ATilapia are very easy to breed. They are extremely fertile and can easily produce hundreds of offspring.

Are tilapia good in aquaponics?

Yes, they are fine. They have a lot of benefits when compared to other fish. One benefit is that they don't require much space. You can buy them from any pet store or online. They are also relatively cheap. 

Tilapia doesn't require any special care and it's not too picky about its water. It will survive in almost any condition. Tilapia is an ideal fish for an aquaponics system as it will grow well on a plant-based diet.

What temperature kills tilapia?

It is safe for tilapia to be raised at temperatures up to 55°F above the water temperature.
Tilapia is an excellent fish for an aquaponic system. In a proper system, it will do very well. I would suggest that you have the tank filled with water and then add your fish.Tilapia are excellent for aquaculture because they’re hardy, fast growing and easy to raise. They’re also cheap to buy. Tilapia can be farmed by anyone and are popular in many different cultures. Tilapia farming can be carried out indoors or outdoors. You can also rear tilapia in tanks or ponds.

Can tilapia fish survive in cold water?

Tilapia can tolerate cold water and even live in water temperatures down to 0 degrees Celsius (32 degrees Fahrenheit).
They are also very resilient, with the ability to withstand a wide range of salinity levels.

What is the desirable water quality for tilapia?

The ideal water quality for tilapia is free of bacteria and nitrate. Bacteria are naturally present in water. They are normally harmless to fish, but if the water contains high levels of bacteria (such as when a reservoir or pond is over-fertilized), they can cause disease in fish.

Nitrate is a naturally occurring compound found in water that causes blue-green algae to grow in water containing too much nitrate. Blue-green algae are very toxic to fish and may even kill them. Nitrates can also be an issue in lakes, ponds and streams. Most water testing services will do this for you. If you don't want to go through the hassle of sending your water to a lab, there are kits available that you can use at home. You can also get kits at your local sporting goods store or bait shop.

Raising Tilapia In Tanks

As we have pointed out that most tilapia species are warm fish. The conclusion is that the temperature requirements of tilapia range from 75 degrees Fahrenheit to 86 degrees Fahrenheit. Temperature below 50 degrees is fatal for your tilapia fish. Temperatures matter a lot when it comes to raising tilapia fish. So if you wish to enjoy optimal growth and a smooth aquaponics system, get the temperature right.

So, we can see that raising tilapia fish in a colder region is not impossible. You just have to go for the appropriate tolerating tilapia species like the blue tilapia. This is because they can withstand temperatures around 40 degrees Fahrenheit. Also, you can simply create a comfortable environment for your warm loving tilapia by making use of the indoor recirculating aquaponics system. This can save heat for your tilapia fish during the cold season.

We also recommend you have a backup or emergency heater so climatic change doesn’t meet you or your tilapia by surprise.
