The Best Animals for Integrated Multitrophic Aquaculture


  • Integrated Multitrophic Aquaculture (IMTA) is a new and eco-friendly way of doing fish farming.
  • People like this method because it helps make less waste and is better for the environment compared to old fish farming ways.
  • IMTA usually means growing various types of animals and plants, like fish, shellfish, and water plants, in a way that looks like how nature works.
  • The friendly partnership between these creatures makes the fish farming place more balanced and it can look after itself without needing a lot of help.
  • The big idea in IMTA is to use one species’ waste as food for another.
  • Doing this doesn’t just help the environment, but it also makes fish farming work better and It makes it so fish farming can keep going for a longer time.
  • IMTA is a big change in fish farming, moving towards methods that are better for the environment and can keep going for a long time.
  • Next, we’ll look more closely at the kinds of IMTA systems, what things you need for work, and the different animals and plants you can use to get the best outcomes.


  • In IMTA, polyculture means that people who do fish farming grow many types of animals at the same time, and these animals can live together happily in the same water .
  • This could mean having fish, shellfish, and seaweed all together.
  • Every kind of animal or plant in the system has a job to do.
  • One helps clean up the waste made by another.
  • This way of doing things makes a balanced and connected system that uses resources in the best way possible.

Integrated Recirculating Aquaculture

  • In Integrated Recirculating Aquaculture, fish farmers keep cleaning and reusing the water in their fish farm all the time.
  • Doing this helps protect the environment and saves water.
  • It also keeps the water good for the fish and other water animals.

Seaweed-Shellfish Polyculture

  • In this IMTA system, people grow seaweed and shellfish together.
  • Seaweed is a kind of algae that can take extra wastes from the water and make the water better.
  • At the same time, shellfish such as mussels and oysters eat tiny creatures and natural stuff means dead plants and small living organisms found in the water .
  • Doing both of these things together makes it so there’s not too much wastes in the water and the whole system works better.
  • Fish farmers have different IMTA methods to choose from, so they can pick the one that works best for what they want, what they have, and what’s good for the environment.
  • Every method has special advantages, and these help make fish farming more sustainable.
  • Next, we’ll talk about the important parts needed for IMTA systems to work well and look at the specific animals and plants that can be used to get the best results.

Components for Success

Species Selection

  • Choosing the right animals and plants to live together in the same fish farming system is a very important part of making IMTA work well .
  • For example, picking fish that make good food and other species like algae or filter feeders can help make a balanced system.

Nutrient Cycling

  • The heart of IMTA is about how waste from one species becomes food for another .
  • It’s just like how things get reused in nature.
  • When nutrient recycling works well, there is less wastes, and it helps keep the whole system clean.

Efficient Monitoring Systems

  • Keeping an eye on things and gathering information is really important for making IMTA work well.
  • Continuous observation of water quality, species health, and nutrient levels ensures that the system remains in balance.
  • Keeping a close watch helps fish farmers fix problems quickly and stop things from going wrong in the system.

Environmental Considerations

  • When making IMTA systems, it’s important to think about the environment and plan carefully. 
  • Things like how warm the water is, how salty it is, and how the local environment works are very important in deciding if the animals and plants you choose will work well, and if the whole system will be a success.
  • We need to check how things affect nature and do things in a way that keeps our Earth clean and healthy.
  • To make a good fish farm that takes care of the environment and works well, these things are really important.
  • They help create a system that can support itself, is kind to nature, and works efficiently.
  • Next , we’ll look at which animals work best for IMTA and why it’s a good idea for both money and the environment.

Ideal Animals for IMTA

  • In IMTA, a good plan is to put fish and shellfish together.
  • At the same time, mussels and oysters clean the water by eating tiny plants and debris.
  • This mix makes a balanced system that reduce wastes and makes better use of resources.

Algae and Seaweed

  • Algae and seaweed are really important in a lot of IMTA systems.
  • They absorb extra nutrients in the water, making the water better and by preventing too many nutrients from building up. 
  • Also, growing algae and seaweed can bring in extra money in IMTA setups.

Filter Feeders

  • Some kinds of shellfish, which filter the water, are great choices for IMTA.
  • These shellfish are very important in keeping the water clean because they actively remove small particles and extra nutrients from the water.
  • When we add filter-feeding animals to the setup, people who farm fish and other water animals can make the water cleaner and recycle more nutrients.
  • Choosing the right mix of animals depends on what the fish farm wants to achieve and whether the selected animals can work well together in the IMTA system.
  • These animals help to reduce waste, improve water quality, and create a balanced system for integrated multitrophic aquaculture.
  • In the last part, we’ll talk about why it’s a good idea for both money and the environment to use IMTA methods.

Save Money

  • We can save money on food and power by mixing fish farming, seaweed, and shellfish farming.
  • This means we can produce more food in the same area.


  • IMTA helps decrease the pollution caused by fish farming.
  • when fish make waste, seaweed can eat it, which keeps the water cleaner.

Less waste, more taste

  • IMTA is good for the environment because it reduces the waste and produce extra food than traditional aquaculture.

Getting More Food with Less Effort

  • When we grow different kinds of creatures together, they can support each other.
  • It’s like teamwork in your underwater garden. Fish, seaweed, and shellfish cooperate to make everything grow better.


  • In short, using integrated multitrophic aquaculture (IMTA) is a good and eco-friendly way to do fish farming. 
  • This is a method that helps nature and can make money for you.
  • When you put different water animals together and take care of how they work together, IMTA can make less wastes, give you more fish, and make the environment clean and healthier.
  • By using different kinds of fish and being kind to the environment, IMTA makes it possible to have a better future for fish farming.
  • We suggest you try using IMTA and think about using these methods in your fish farming.
  • This can help make fish farming better for the environment, more effective, and also good for your pocket.
  • You can help make seafood production better for the environment.
