Symbiotic Between Oreochromis niloticus Fingerlings and Some Medicinal Plants: Growth Performance and Water Quality Enhancement

Aquacultural scholars and experts should create new plans to sustain aquaculture, with a minimum negative impact on the environment since aquaculture activity affects the environment and is further complicated by the paucity of good-quality water and land. As a result, a symbiotic experiment involving fish and plants was carried out to ascertain how the two organisms affected one another. The deep Flow Technique was created as a hydroponic system in its simplest form. Mentha spicata L. (mint) at 46 cm TL, Ocimum basilicum L. (basil) at 43.5 cm TL, Origanum majorana (marjoram) at 37 cm TL, Salvia Rosmarinus (rosemary) at 33 cm TL, and Origanum syriacum (thyme) at 34.7 cm TL were the plants utilized in this experiment. 400 fish/pond (1.3 g wet weight) of the Oreochromis niloticus L. species of tilapia fingerlings were stocked. A commercial feed for specific species (with a crude protein content of 25 percent) was represented as the diet in this experiment. Four plants and a control treatment comprised the five treatments, each of which had three replicates. The findings showed that using medicinal herbs improved the quality of the water, especially when compared to un-ionized ammonia (NH₃) values in both basil and marjoram. Basil and mint ponds had the greatest fish performance results without any discernible variations, while rosemary ponds had the best survival rate at 96.25%. The performance of some medicinal plants as well as the purity of the water is both benefited by symbiotic relationships with both fish and plants. In order to assess the impact of intense culture on the effectiveness of this program, more studies must be conducted.
