NSERC Canadian Integrated Multi-Trophic Aquaculture Network

The IMTA Logo

Integrated Multi-Trophic Aquaculture, and its acronym IMTA, were first coined in 2004 at a workshop in Saint John, New Brunswick, Canada. Soon, it became obvious that the IMTA concept needed to be visually branded for ease of comprehension and recognition. The IMTA logo was designed in 2007.

The two arrows symbolize the recycling of nutrients, food and energy among the responsibly co-cultivated organisms within the aquaculture system and with the surrounding ecosystem. The organisms in the inner circle represent key complementary trophic components of an IMTA system cultivated in proximity: fed aquaculture (represented by a fish), organic extractive aquaculture (represented by a shellfish) and inorganic extractive aquaculture (represented by a seaweed). The drawing of these organisms is purposely generic, as species may vary according to the regions where the many variations of IMTA systems are ecologically engineered.
