Aquaponics systems are sustainable, closed systems that utilize fish waste as a mode of fertilization for various crops. Historically, aquaponics systems have mostly used fish such as tilapia, cod, and catfish rather than other aquatic life; however, an increasing number of aquaponics farmers have been successfully using crayfish, shrimp and prawns. A wide variety of plants have been grown in aquaponic systems. Allelopathic plants, or plants that are able to inhibit or enhance growth of other plants by releasing certain chemicals from their roots to interact with nearby plant roots, have not been studied in aquaponic systems. The following paper provides a details of a research study completed to observe the effects of garlic allelopathy on tomato plants within a crayfish aquaponic system. This study has the potential to optimize crop growth and yield in personal and commercial aquaponics systems, as well as broaden the understanding of how environment plays a role in the efficacy of allelopathic chemicals.
