Freshwater Biota

The highly use of polyethylene plastics in Indonesia has negative impact toward freshwater aquaculture systems. Omnivorous fish is one of the freshwater biota that exposed by microplastics. This study aims to determine the effect of microplastics to water quality and the prevalence of microplastic exposure in tilapia. The experimental design is conducted using a microplastic exposure (polyethylene scrub) with concentration of 0.01 g/L (P1), 0.1 g/L (P2), and 1 g/L (P3). Each treatment is repeated 3 times. The organ groups observed are the gastrointestinal, liver, gills, and gonads. The stages of the research including fish raising, microplastic extraction, water quality measuring parameter, and counting the amount of microplastics. The result obtained for water quality parameter is temperature, pH, and dissolved oxygen still within safe fish farming limit. Microplastics at high concentration in water can cause a decrease in the total value of ammonia and do not affect the value of water temperature, pH, and dissolved oxygen. Microplastics are found in the digestive organs, liver, gills, and gonads. The digestive tract of tilapia is the organ with the most microplastics after 14 days of exposure. It is concluded that microplastic is harmful for the life of tilapia because it can absorb to the liver and gonads.

Osteochillus hasselti was commonly inhabit the Lubuk Siam Lake. A research aims to understand the standing stock of O. hasselti in that lake was conducted in July to August 2018. The fish was sampled everyday for 10 days in July and 10 days in August, in 3 sampling points (in the inlet area, in the middle of the lake, and the outlet) using gill nets. The standing stock was analyzed using Leslie method. Results shown that the initial population (No) of the fish was 315 kg and the final population (Nt) was 301 kg and the exploitation level was 8%. The water quality parameter shown that temperature was 27-28oc, clarity 6395 cm, pH = 6 and dissolved oxygen was 5.32–5.40 mg/L. Data obtained indicate the water quality in the Lubuk Siam Lake is good and it is able to support the life of O. hasselti.

Optimal salinity on rearing media is needed to get the best production performance of climbing fish culture. The aim of this experiment is to get an optimal salinity on rearing media of climbing fish. This experiment was conducted in wet lab of Research Institute for freshwater Aquaculture and Fisheries Extension. The treatments were different salinities on rearing media; 0 ppt, 3 ppt, 6 ppt and 9 ppt. Each treatment has 3 replicates. Experiment design use completely randomized design. The initial weight of fish was 1 ± 0.11g and initial length of fish was 2 ± 0.3 cm. Aquaria of 40x22x20 cm was used for rearing media. Each aquarium with 15 lt of water was stocked 350 fish. Fish was fed frozen blood worm (protein contains of 62.5%) at ad libitum. Duration time of rearing was 40 days. Sampling was conducted every 10 day for fish weight, lenght and water quality. The result showed that optimal salinity of survivale rate, specific growth rate and total length were on salinity of 1.8 ppt, 2.5 ppt and 3.3 ppt. The value of water quality parameter in aquaria such as temperature, pH, Oxygen, nitrite, nitrate an amonia is still feasible for climbing fish rearing.

This paper presents a multiparameter water quality sensor chip with temperature compensation. The sensor chip was manufactured using microelectromechanical system (MEMS) technology. The surface of the chip integrated pH, dissolved oxygen (DO), ammonia nitrogen, and temperature sensors. To compensate for the solution temperature, the chip was also designed with a sandwich, plate-type serpentine Pt resistance heater. The experimental results showed that the pH sensor had a high sensitivity of 0.288 mA/pH with good linearity ( R 2 = 0.9998 ), the sensitivity of the temperature sensor was 0.949 Ω/°C, the sensitivity of the ammonia nitrogen sensor was 0.1139 mA/ppm, the sensitivity of the dissolved oxygen (DO) sensor was 2.22 μA/ppm, and the sensitivity of the temperature changes with respect to the heater power was 0.3126°C/mW. Compared with a single water quality parameter sensor, the as-prepared sensor chip could simultaneously detect multiple parameters of a water sample and had a good temperature compensation effect. Moreover, the sensor chip was small in size, rugged, and highly accurate.

Nine runoff containment basins (RCBs), used directly or indirectly for irrigating plants in ornamental plant nurseries, and one adjacent stream were sampled for water quality between Feb. and July 2013 in Maryland (MD), Mississippi (MS), and Virginia (VA). Triplicate water samples were taken monthly. Analysis was done for 18 water quality variables including nitrate-nitrogen (NO3−-N) and ammonium-nitrogen (NH4+-N), orthophosphate-phosphorus (PO4-P) and total-phosphorus (T-P), potassium, calcium, magnesium, sulfur, aluminum, boron (B), copper (Cu), iron (Fe), manganese, zinc (Zn), pH, total alkalinity (T-Alk), electrical conductivity (EC), and sodium. Additionally, 15 RCBs from 10 nurseries in Alabama (AL), Louisiana (LA), and MS were sampled in 2014 and 2016. Most prevalent correlations (P = 0.01) were between macronutrients, EC, B, Fe, and Zn, but none were prevalent across a majority of RCBs. Water quality parameter values were mostly present at low to preferred levels in all 25 waterways. Macronutrient levels were highest for a RCB that receives fertility from fertigation derived runoff. Water pH ranged from acidic to alkaline (>8). Results of this study show water quality in RCBs can be suitable for promoting plant health in ornamental plant nurseries, but also shows levels will vary between individual RCBs, therefore demonstrates need to verify water quality from individual water sources.

Water Quality Indicators

The growth and development of fish depend on the physicochemical properties of water, such as temperature, turbidity, concentration of hydrogen ions (pH), dissolved oxygen, total alkalinity, total hardness, nitrates, nitrites, etc. The article presents data on the hydrochemical regime of growing ponds of the farm “Rudnyky” of Lviv region. Studies have shown that the water quality indicators of growing ponds during the growing season are within the normative values and the water is suitable for fish farming. In the breeding ponds of the Rudnyky fishery, the water quality indicators fluctuated within the following limits, namely: the hydrogen index (pH) was within the maximum permissible concentrations (6.7–8.0). The content of dissolved oxygen in the water during the growing season was within normal limits (6.5 to 7.8 mg/l) and fully met the requirements for carp fish ponds, the alkalinity of the water was average and varied between 2.40 and 3.20 mg-eq/l, permanganate and dichromate oxidation varied slightly – 8.6–15.45 mgO/l and 25.6–40.50 mgO/l, which corresponds to the normative indicators for fish farming. The concentration of ammonium nitrogen (NH4+) in the growing ponds of the farm averaged 0.008–0,520 mg N/l, the content of nitrites and nitrates was 0.002–0.100 mg N/l and 0.060–0,520 mg N/l, respectively. The average concentration ranged from 0.10 mg P/l to 0.40 mg P/l of mineral phosphorus (PO4-3), which did not exceed the normative values. The amount of total iron in the water of the pond did not have high values, averaged 0.10–0.38 mg Fe/l, which was within the maximum allowable concentrations. The values of total hardness of water were determined as moderately hard and were in the range of 2.9–5.0 mg-eq/l. The salt composition of pond water was characterized by total mineralization, the ratio of ions and the content of chlorides, sulfates, bicarbonates. During the study period, the content of chlorides (Cl-) sulfates (SO4 2-); hydrocarbons (HCO3-), did not exceed the maximum allowable concentration. Among the cations in the pond water, calcium ions (Ca2+ ) predominated, their content averaged 28.2–80 mg Ca/l. In the studied pond, the concentration of magnesium (Mg2+) reached average values – 6.8–20.0 mg/l. The total mineralization of water was 300.4–440.4 mg/l. By the nature of the ionic composition, the water of the growing ponds belongs to the hydrocarbonate composition of the calcium group.
