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.

Rainbow trout is a new fish farming object for Uzbekistan, the adaptability of which (first of all, growth) to local conditions should be carefully studied. We analyzed the growth of rainbow trout in the conditions of flowing pools and cages in the foothill zone of Tashkent province of Uzbekistan. From March to October, the water temperature in the Khojikent reservoir varied from 4.9 to 13.1 °C, the amount of dissolved oxygen was 8.4 to 11.5 mg/l, and the pH was 7.40 to 7.67. In the flowing basin, the temperature was 15-18 °C, pH 7.2-7.5, the amount of dissolved oxygen 6.1-11.2 mg/l. The conditions of the foothill zones of Uzbekistan in terms of water quality are favorable for the development of trout breeding. During the season, fish in cages increased from 250 g to 623 g, in pools from 25 g to 390 g on average. The waste was 1.7%. The actual fish productivity of the basin is 39 kg/m3, the cage is 30 kg/m3 and the feed coefficient in the basin is 1.2, in the cages - 1.09.

Monitoring variables such as dissolved oxygen, pH, and pond temperature is a key aspect of high-quality fish farming. Machine learning (ML) techniques have been proposed to model the dynamics of such variables to improve the fish farmer’s decision-making. Most of the research on ML in aquaculture has focused on scenarios where devices for real-time data acquisition, storage, and remote monitoring are available, making it easy to develop accurate ML techniques. However, fish farmers do not necessarily have access to such devices. Many of them prefer to use equipment to manually measure these variables limiting the amount of available data to process. In this work, we study the use of random forests, multivariate linear regression, and artificial neural networks in scenarios with limited amount of measurements to analyze data from water-quality variables that are commonly measured in fish farming. We propose a methodology to build models in two scenarios: i) estimation of unobserved variables based on the observed ones, and ii) forecasting when a low amount of data is available for training. We show that random forests can be used to forecast dissolved oxygen, pond temperature, pH, ammonia, and ammonium when the water pond variables are measured only twice per day. Moreover, we showed that these prediction models can be implemented on a mobile-based information system and run in an average smartphone that fish farmers can afford.

Corn is a seasonal plant. Corn is one of the crop commodities that has an important role in agriculture and the economy in Indonesia. Problems that often occur in the cultivation of corn (Zea mays) are such as water availability, land area, weather, disease and pest attacks. Insects are animals which include an important role in the agricultural ecosystem, but not all insects are beneficial for these plants. Insects also consist of several types of Orders, namely the Order of Coleoptera, Order of Diptera, Order of Lepidoptera, Order of Homoptera, Order of Hemiptera, and Order of Thysanoptera. Insects also have their respective statuses as predators, pests, pollinators, and suckers. This study aims to identify the types of insects on cornfields and determine the effect of abiotic factor correlations on the number of insects on cornfields. This research uses quantitative descriptive method, the retrieval of insects with the absolute method and this study makes direct observations (visual) and the determination of plots using purposive sampling. The results showed 5 orders (Odonata, Lepidoptera, Orthoptera, Coleoptera, and Hemiptera), 6 families (Libellulidae, Nymphalidae, Pieridae, Acrididae, Coccinellidae, and Pentatomidae) and 9 kinds of insects. The most common insects are found in the Odonata Order, as many as 51 birds and the least insects found were found in the order of 2 Lepidoptera Familia Acrididae. Abiotic factors measured are temperature, humidity, wind speed and light intensity. Wind speed is related to the arrival of insects that come on cornfields.

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.
