Whitesel 2 Focus of Essay: In an age with decreasing farmland and marine populations but an increasing population, food insecurity is on the rise. As nations face this dilemma, they are generating innovative ways to increase food production. By combining aquacultural production of seafood and hydroponic production of plants, the highly efficient aquaponics was born. Aquaponics is an emerging but underutilized agricultural form that consumes less resources than other practices and can be used in non-traditional environments. Research and Analysis: Hydroponics is one of the most promising agricultural methods because it does not require soil. The process has evolved further by adding aquaculture or farmed seafood to the growing system. The amalgamation of the two resulted in aquaponics. The semi-closed system has plants grown at the top of the water and animals reside below or in a separate but connected tank. Microorganisms transform fish waste into nutrients the plants need, and plants replenish the water with nutrients the fish need, creating symbiotic environment. Farmers can manipulate the nutrients their plants receive through fish feed (Maguire et al). Some plants are found to grow faster in fish wastewater than regularly. Commonly used fish species are tilapia, perch, carp, barramundi, cod, and trout (Maguire et al). There are multiple different types of aquaponic growing systems. Deep water culture supports the plants with rafts that float on a channel of water fish had lived in (What is Aquaponics). This technique is most utilized commercially for fast-growing, low-nutrient produce like leafy greens. Media-based aquaponics grows the produce in various media like clay pellets or shale (What is Aquaponics). The media filters a variety of chemicals and removes solid waste. Media based systems are recommended for home use

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
