Ebook "Recent freshwater ostracods of the World: Crustacea, ostracoda, podocopida" is richly illustrated with distribution maps, line drawings of key generic characteristics, and numerous SEM photographs. Serving as an excellent starting point for all further research on freshwater ostracods, it can be widely used not only by ostracodologists, but also by crustaceologists, evolutionists and ecologists.

Correlated genetic response in survival to selection for high growth has not been reported in giant freshwater prawn (GFP) (Macrobrachium rosenbergii). The main aim of this study was to measure genetic changes and estimate heritability for this character (survival rate) and its genetic associations with body traits in a GFP population selected over eight generations from 2008 to 2015.

Seven microalgae strains from samples collected from freshwater lakes in Central Vietnam were isolated and cultivated in BBM medium for investigating their biological characteristics and their applicability. These strains were identified belonging to 6 species, 3 genera of the family Scenedesmaceae, division Chlorophyta.

A new freshwater ostracod genus, Comalcandona gen. nov., and its type species (Comalcandona tressleri sp. nov.) are described from John Knox Ranch, Comal County, Texas, USA. The new genus differs from the related genera in the presence of the shallow pits on the trapezoidal shape of the carapace and presence of one well-developed anterior claw (posterior claw and both anterior and posterior setae are absent) on the uropod, a diagnostic character.

For water quality assessment, based on TCVN 7220-2: 2002, the water in Van Long RAMSAR is in low level of pollution. According to ASPT index on average (3.42), this parameter was under medium to heavily polluted. The results recommend utilizing family taxon of macrozoobenthos with the recorded scales to assess quality of aquatic environments of freshwater bodies in northern Vietnam.

This study, the first such attempt in Turkey, aimed to investigate the distribution of diatom species related to the variation of total phosphorus (TP) in eight basins to determine trophic weight and indicator values of diatom species and to develop the Trophic Index-Turkey (TIT) for assessing the ecological status of freshwaters. The distribution of the diatom species in 225 running water bodies from 8 basins of Turkey was determined in 2014 (summer and fall) and 2015 (spring and summer) in association with TP variation.

Bioassessment of surface waters is one of the most important approaches to predict the deterioration of ecosystems and achieve environmental sustainability according to the application of the European Water Framework Directive. The present review emphasizes the importance of the bioassessment of freshwater quality especially running waters based on diatom metrics. Nutrient enrichment and hydromorphological alternation driven by human activities are the main factors for the ecological compromise of freshwater ecosystems.

Lake Baikal is one of the oldest freshwater lakes and has constituted a stable environment for millions of years, in stark contrast to small, transient bodies of water in its immediate vicinity. A highly diverse endemic endemic amphipod fauna is found in one, but not the other habitat. We ask here whether differences in stress response can explain the immiscibility barrier between Lake Baikal and non-Baikal faunas.

Water retting of whole jute (Corchorus olitorius L.) plant is convenient to the majority of farmers. Jute bundles are extensively retted in isolated stagnant inland freshwater bodies, often having insufficient water, during the months of August–October in the Indo-Bangla subcontinent. It leads to transportation expense, improper retting with low fibre quality, complete loss of huge organic retting residue and transitory deterioration of the aquatic environment affecting local ecology.

The freshwater copepod Mesocyclops Sar, 1914, a species-rich genus within the family Cyclopidae Rafinesque, 1815, is common in tropical areas. In addition, the genus members are used for the biological control of mosquito larvae (Anopheles, Aedes) which are vectors for transmitting dengue fever. In Vietnam, a total of 11 Mesocyclops species have been recorded in inland freshwater bodies. Of which, one endemic species (M. sondoongensis Tran & Hołyńska, 2015) and two species were described from Vietnam, namely M. yenae Hołyńska, 1998; M. ferjemurami Hołyńska & Vu, 2000.

The ichthyo-fauna in the Ba Che and Tien Yen rivers, northern Vietnam is highly diverse, with a total of 245 species determined. However, data on the distribution of fish species are not sufficiently provided for the whole area. This study was conducted from 2008 to 2011 at 27 stations from the Ba Che and Tien Yen river basins to determine the distribution of fish species according to different sections of the rivers, water bodies, seasons, and salinity levels.

This study was conducted to enhance the understanding of phytoplankton diversity of Duyen Hai town, Tra Vinh province. We selected 12 representative sampling sites and investigated phytoplankton diversity in both dry and rainy seasons. The phytoplankton of this area were comprised of 134 species, belonging to 64 genera, 45 families, 31 orders, 8 classes and 5 divisions. Among those divisions, Bacillariophyta was the most dominant in species, accounting for 70% of the total number of species and Cyanobacteria commonly had high density at 12 surveyed sites.

The effect of oral administration of probiotic, biogut on growth, survival, and immuno response and disease resistance against white muscle disease was examined in freshwater prawn, M. rosenbergii. Biogut was administered to prawn through the diet at 1%, 1.5% and 2.0% body weight/day for a period of 90-day in recirculatary rearing system. The prawns were sampled on 90 day and challenged with white muscle disease virus, which is highly potential disease to prawn through injection route at 50 μl / juvenile.

Dark body disease has become a serious problem for climbing perch, Anabas testudineus, cultured in freshwater intensive farming systems in Vietnam. Outbreaks of the disease occur when the fish are about 20-65 days old with 40 - 100% mortality. The main clinical signs of the disease are dark body, haemorrhagic or yellowish liver, and little or no food in the intestines.

A computer-based database for freshwater algae recorded in Turkey has been established. The first phase of the project involved the selecting of data types available for freshwater algal species occurring in Turkey. Such data were obtained from algal studies previously carried out in various freshwater bodies of the country.

Striped catfish (Pangasianodon hypophthalmus) occur in freshwater and brackish water bodies in Asian countries. However, there are few published papers on the effects of salinity on the physiological characteristics of the striped catfish although seawater levels are predicted to increase in the future.
