Aquaponies is one way to reduce water pollution produced by fish fanning, it can also be an alternative to reduce the amount of water used in the aquaculture system. Water quality is an important factor in fish fanning activities because it can affect the growth and development of fish cultivated in reservoir waters. The purpose of this study was to analyze the water quality of the KJA (floating net cages) layered with the aquaponic system tested in the waters of the Koto Panjang Hydroelectric Reservoir. Tins research was conducted in June - August 2020 at the Koto Panjang Hydroelectnc Reservoir. Measurement of water quality parameters is earned out directly at the research location. The analysis of the physical and chemical parameters of the waters is measured in the laboratory and the calculation of the water quality parameters refers to the APHA-AWWA and is compared with Government Regulation Number 82 of 2001 concerning Class II water quality standards. Based on the results of observations on water quality in layered cages with the aquaponies system, it is known that temperature parameters range from 31-33°C. pH ranges from 5-6. dissolved oxygen ranges from 9.38 - 9.65 mg / L. free carbon dioxide ranges from 9.14 - 11, 12 mg / L and brightness range from 148.9 to 156.2 cm. Meanwhile, nitrate parameters ranged from 0.03-0.04 mg L and phosphates ranged from 0.30 to 0.06 mg L. The water quality in the layered marine cage in the aquaponies system in the Koto Panjang Hydroelectric Reservoir has been able to reduce nitrate and phosphate content so that it can reduce the impact of organic pollution that occurs in the waters of the Koto Panjang Hydroelectric Reservoir.

The problem most often encountered in fish farming is disease which can cause a decrease in fish production levels. Parasites cause one of the infectious diseases found in fish farming. The presence of parasites can cause a decrease in the quality of the growth of fish production. The purpose of this study was to identify the prevalence of ectoparasites on Nile tilapia in Sidoarjo, Indonesia. Ninety-six samples from two ponds were examined under the microscope to find out the presence of ectoparasite that exists in the outside body part of the fish. Samples were collected from skin, fins, tail, and gills using native methods and observed under a microscope in the Division of Parasitology Laboratory, Faculty of Veterinary Medicine, Universitas Airlangga. The results of this study showed 86 samples positively infected by ectoparasite and 10 showed negative. The ectoparasites found in this study were Trichodina sp., Chilodonella sp., Ichthyophthirius multifillis, Gyrodactylus sp., and Dactylogyrus sp. The highest prevalence is Trichodina sp. and Dactylogyrus sp. The number of fish infested by ectoparasite is 89.56%, this is classified in the usual category. The highest prevalence occurs in infestations of Trichodina sp. i.e.72.91% which were contained in the 70 samples. While the lowest prevalence was in Gyrodactylus sp. by 8.32% in 8 fish samples. Double infections from two different ponds were 70% within 33 samples which were included in the usual category.
