Red tilapia, Oreochromis niloticus is the main commodity of freshwater fish in Indonesia. Red tilapia have a good price compared to tilapia. The aims of this experiment to determine of survival, growth, and water quality of red tilapia cultured in aquaponic system. The treatment of this experiment, namely A) Red tilapia cultured without aquaponic (control), B) Red tilapia cultured with pakcoy, and C) Red tilapia cultured with caisin. The result showed that the highest of survival rate, weight, and length absolute found at Red tilapia cultured with pakcoy (96.00±1.73%, 32.31±0.74g, and 7.57±0.21 cm) and Caisin (96.00±1.73%, 32.31±0.74g, and 7.57±0.21 cm) than that of without aquaponic (86.67±1.15%, 25.77±1.05g, and 6.43±0.31 cm) (P<0.05). Vegetable leaf production of pakcoy was 6.57±0.16 Kg and Caisin was 6.17±0.11 Kg. The water quality parameters such as DO, TAN, nitrite, and nitrate of Red tilapia cultured using aquaponics was better than that of without aquaponic.

An ectoparasitic infection is one of the causes of losses for the farmers of red tilapia (Oreochromis niloticus). This study was aimed to determine the types of parasites, the level of attack includes the prevalence, intensity and dominance of ectoparasites in red tilapia by adding fermented copra meal to the feed. The research was carried out at the Maros Fish Farming Center, South Sulawesi, while observing parasites in fish were carried out at the BRBAPPP Fish Pathology and Health Laboratory, Maros. The treatments were tested by addition of fermented copra meal as follows: (A) 0% control; (B) 15%; (C) 30% and (D) 45%. The experimental feed was applied to the fish once a day by satiation. The parameters observed were 1) identification of parasites; 2) prevalence rate; 3) attack intensity; 4) dominance and 5) water quality. A total of 30 tilapia from containers were taken to observe the fish organs included, ectoparasites were observed using a smear method on the target organ (gills, scales and fins and eyes), then examined microscopically. The ectoparasites were identified based on Kabata (1985), Grabda (1981) and Moller and Anders (1986). The result found two types of parasites namely Argulus sp. and Epistylis sp. The result of the prevalence of Argulus sp. of treatments A, B, and D were obtained (3.33%) and intensity (1 ind/fish) except that Treatment C was obtained prevalence and intensity (0%). While the highest prevalence rate of Vorticella sp. in A (Control) was 20% (frequent infections) while other treatments were still relatively low at 3.33% - 13.3% (sometimes infections) with intensity of attacks 0-1 ind / fish (low infection rate). The dominance value in all treatments ranged from 0.1 to 0.85%. The range of water quality of fish container were temperature 26.3-29.2 °C, pH 7.5-7.8, DO 5.8-6.4 ppm and ammonia 0.02-0.26 ppm. The value was within good range for Red Tilapia.

Urban development, agricultural runoff and industrialization have contributed pollution loading on the environment.  In this study Hemavathi river water from a stretch from its origin point to its sangama was studied for pollution load by determining parameters of water quality like pH, Alkalinity,  Ca, Mg, Nitrate, TDS, BOD, COD , and the results were compared with WHO and BIS standards to draw final conclusion on the quality of water.

Changes of microbial indices of water quality in the Vistula and Brda rivers as a result of sewage treatment plant operationThis paper reports the results of studies of microbiological changes in the water quality of the Vistula and Brda rivers after the opening of sewage treatment plants in Bydgoszcz. The study involved determining the microbiological parameters of water quality. Based on the results obtained, it was found that the quality of the water in both rivers had improved decidedly after the opening of the plants, although an increased number of individual groups of microorganisms was found at the treated sewage outlet from one of the plants.

Environment Degradation

Environment degradation in Rawa Pening’s lake is caused of descend lake’s functions for some potentions and activities around the lake. Some problems in the Rawa Pening’s lake has emerged i.e : decrease water quality of lake, abundance of water hyacinth growth and increase sediment in the bottom lake. A research about infl uences of land ecosystem on Panjang and Galeh river corridors for Rawa Pening’s lake has been done. Two rivers named Galeh and Panjang are the largest water contribution in Rawa Pening’s lake. That caused the land characteristic ecosystem of that river corridors gives infl uences in the Rawa Pening’s lake.Key words: land ecosystem, river corridor, water contribution, Rawa Pening Lake.
