Horizontal Distribution of Psammonic Ciliates in Two Lakes of Different Trophic Status: Relationship to Physical and Chemical ParametersThe aims of this study were to identify the taxonomic diversity and abundance of psammonic ciliate communities in mesotrophic and eutrophic lakes (Łęczna-Włodawa Lakeland, eastern Poland). The effect of selected physical and chemical water parameters on ciliates community was also analysed. Psammon samples were collected during three seasons: spring, summer and autumn of 2010. In each lake, in the psammolittoral, samples were collected in the euarenal, higroarenal, and hydroarenal zones. A total of 53 ciliate taxa were recorded. The highest value of the Shannon-Weaver index was recorded in summer in eutrophic lake (2.79). At the same time in mesotrophic lake, a lower value of the index was determined (0.79). The mean numbers of ciliates ranged from 516 ind.cm-3in the eutrophic lake to 191 ind. cm-3in the mesotrophic lake. In eutrophic lake, the highest number of ciliates was recorded in the euarenal (649 ind. cm-3), and the lowest in the higroarenal (425 ind. cm-3). In the mesotrophic lake, the highest average numbers were determined in the higroarenal (235 ind. cm-3), and the lowest in the hydroarenal (155 ind. cm-3). Irrespective of the lake trophy, Hymenostomata (Paramecium sp., Glaucoma sp., Uronema nigricans) occurred in the highest numbers (from 13 to 95%). The results demonstrated that N-NH4, P-PO4and TOC can strongly regulate the abundance and taxonomic composition of ciliates. The strongest correlations between numbers of ciliates and physical and chemical water parameters were observed in the higro- and hydroarenal zones of the eutrophic lake.

Cikeruh River is a Citarum tributary that has received a lot of waste inputs, so that will affect the quality of river water and cause differences in aquatic fertility. Aquatic fertility can be determined by calculating plankton abundance and distribution. The purpose of this study was to map the spatial distribution of plankton along the Cikeruh River. The study was conducted in June 2019 to August 2019  at five stations with the purposive sampling method. The parameters observed were physical and chemical parameters of waters, plankton abundance, diversity index, dominance index, species deficit, and Morisita index. The results showed that plankton was identified as many as 33 phytoplankton genera and six zooplankton genera, the spatial distribution of plankton in the Cikeruh River was different at each station, at station 1 consisted of 14 phytoplankton genera, station 2 27 phytoplankton genera, station 3  24 phytoplankton genera, station 4 25 phytoplankton genera, and at station 5 was  found 22 phytoplankton  genera. The abundance of plankton obtained ranges from 1823-5972 ind/L. Phytoplankton diversity index obtained from ranges 0.71-0.84, while the zooplankton ranges 0.17-0.32 with  phytoplankton dominance index 0.16-0.35 and zooplankton 0.68-0.83. Phytoplankton morisita index obtained from ranges 1.37-2.17, while the zooplankton ranges 1.03-2.31. Physical-chemical parameters observed as follows: Temperature 18.58ºC – 27.77ºC, light transparency 16,68 cm -31.92 cm, current 0.17 m/s -0.35 m/s, DO 3.35-8.05 mg/L, CO2 8.36 -37.05 mg/L, pH 7.53 – 8.66, BOD5 10.83 - 25.42 mg/L, Nitrate 0.18-0.26 mg/L,  phosphate 0.18-0.26. The physical and chemical parameters qualify for Indonesian  Government  Regulation  No. 82  of  2001  class II and III.

Haris et al, 2019. The Analysis of Water Suitability for Floating Net Sprouts in Sirah Pulau Padang, Ogan Komering Ilir District, South Sumatra Province. JLSO 8(1):20-30.The purpose of this study is to analyze the level of water suitability of the floating net sprouts in sirah pulau padang, ogan komering river, Serdang Menang Village, OKI South Sumatra Regency based on water physical and chemical parameters. This study was conducted on July - August 2018 at the Komering River, Ulak Jermun village, Terusan Menang Village, and Mangun Jaya Village, OKI District, South Sumatra.

First Time

The present study was conducted in Salt marshes and Salt pans in central parts of Iran. 121 specimens of ants were collected by trapping and hand during spring, summer and autumn 2017 to 2019. Nine species belong to two subfamilies of Myrmicinae and Formicinae were identified. The vegetation, physical and chemical parameters of soil such as salinity, Ph, and other factors were investigated. Darband Shoor Mountain station with five species had the highest diversity and vegetation density and the lowest salinity of soil (72.14 ds/m) whereas Salt Lake station had only one species, with no vegetation and the highest salinity of soil (153.15 ds/m). Cataglyphis lividus (André, 1881) was the dominant species in all the stations except in Darband Shoor Mountain station. All the species were reported for the first time from salt marshes and salt pans in the central parts of Iran and were approved by Prof. Brian Taylor, in Royal Entomological Society of London, England.

The Relationship

The purpose of this study was to determine the relationship between the length and weight of Manggabai fish (Glossogobius giuris) and to know the relationship between the presence of Manggabai fish (Glossogobius giuris) and water quality in Limboto Lake. This research was conducted in February 2019, located in the waters of Lake Limboto, Gorontalo Province. The method used in determining the location of sampling is Purposive Sampling. Fish sampling is determined by considering fishing locations, litoral areas, the presence of residential areas, agricultural and plantation areas, the existence of floating net cages and in the middle of the lake. The study was conducted at 20 observation stations using fish traps in the form of bamboo and used motorcycle tires that have been modified and become traditional fishing gear. The results showed that the physical and chemical parameters in Lake Limboto and showed temperature values ​​ranged from 29.77 to 31.630C, dissolved oxygen levels ranged from 2.1 to 5.48 ppm, pH ranged from 7.09 to 8.94, TDS ranging from 0.251 to 0.369, Nitrite Levels 0.04-0.08 ppm, Nitrate Levels 1.2-4.7 ppm, BOD ranges from 2.5-57 ppm and phosphate levels 0.1-1.14 ppm. The relationship between length and body weight of fish are allometric, where W = 0.8769 L10,023 and constant b (10,023)> 3.
