Abstract

Aquatic environmental management is needed to carry out aquaculture in traditional ponds.The purpose of this study was to reveal and explain the composition of phytoplankton intraditional milkfish (Chanos chanos) ponds in Sidoarjo, East Java. The study was conducted inAugust - September 2024 in traditional ponds in Sidoarjo, East Java. The results showed thatthe plankton community structure found 37 phytoplankton genera in 3 divisions Chrysophyta,Chlorophyta, and Cyanophyta. The values ranged from 2179-27620 Ind / ml which includedmesotrophic waters, the diversity index ranged from 1.92 - 2.72 in the moderate category, andthe dominance index ranged from 0.27 - 0.45 which was classified as low. Air qualityparameters include temperature 30-31,8oC, brightness 38-41,5 cm, pH 9, dissolved oxygen6,87-8,4 mg/L, salinity 7-9 ppt, alkalinity 141-169 ppm, nitrate 0,87-2,35 mg/L, andorthophosphate 0,02-0,089 mg/L. As aquaculture in traditional ponds, air and soil qualitymanagement should be carried out during the preparation and maintenance of milkfish (Chanoschanos) ponds so that aquaculture management is maintained

Abstract

Mystus gulio is a local fish that can open up opportunities for the community. Pollution causes water quality to decrease. Fish are an important indicator in the aquatic environment, Histological analysis can be said to have a function as a natural biological sign to determine the health condition of fish which can be seen from changes in tissue structure in organs exposed to pollutants. Organs that’s vulnerable to water pollution is kidneys.  Kidney tissue is susceptible to damage because kidneys function as a means of filtration and excretion, The method used in this research is descriptive method. Fish were caught from river than dissected to remove the kidneys for histopathological analysis using the HE method, analyzed using the scoring method. The results obtained in both rivers were that fish kidneys caught in the Gembong River were categorized as moderately damaged, while fish kidneys caught from the Rejoso River were categorized as lightly damaged. This is in line with the results of the heavy metal lead from both rivers. Where the yield of lead in fish kidneys caught from the Gembong is on average higher than the yield from fish kidneys caught from the Rejoso.

Abstract

Keting fish is a type of fish from freshwater which is usually used as a consumption fish or ornamental fish. There is a type of kein, namely from the species Mystus gulio (Hamilton, 1922). Mystus gulio ecosystem is disturbed due to land-use change activities in the river which causes the disturbance of the habitat of Mystus gulio. The purpose of this study is to analyze the long-weight relationship, growth pattern, and condition factors of Mystus gulio in downstream Gembong and  Rejoso River. The method used in this study is to sample Mystus gulio from 3 stations on each river based on land use criteria. The research was carried out for 3 months, namely August, September and October 2023. The results of this study show that Mystus gulio caught in these two rivers all have a negative allometric growth pattern (b<3). The average value of the condition factor in these two rivers is 1 which indicates that the condition of Mystus gulio is good. The average growth of Mystus gulio caught in Gembong is relatively larger than Rejoso. The waters quality results of Gembong and Rejoso are still in optimal condition, except for Total Suspended Solid and Lead (Pb).
