Transcriptome Sequencing and Analysis of Wild Amur Ide (Leuciscus Waleckii) Inhabiting an Extreme Alkaline-Saline Lake Reveals Insights Into Stress Adaptation
Transcriptome Sequencing and Analysis of Wild Amur Ide (Leuciscus waleckii) Inhabiting an Extreme Alkaline- Saline Lake Reveals Insights into Stress Adaptation Jian Xu1, Peifeng Ji1, Baosen Wang1,2, Lan Zhao1, Jian Wang1, Zixia Zhao1, Yan Zhang1, Jiongtang Li1, Peng Xu1*, Xiaowen Sun1* 1 Centre for Applied Aquatic Genomics, Chinese Academy of Fishery Sciences, Beijing, China, 2 College of Life Sciences, Tianjin Normal University, Tianjin, China Abstract Background: Amur ide (Leuciscus waleckii) is an economically and ecologically important species in Northern Asia. The Dali Nor population inhabiting Dali Nor Lake, a typical saline-alkaline lake in Inner Mongolia, is well-known for its adaptation to extremely high alkalinity. Genome information is needed for conservation and aquaculture purposes, as well as to gain further understanding into the genetics of stress tolerance. The objective of the study is to sequence the transcriptome and obtain a well-assembled transcriptome of Amur ide. Results: The transcriptome of Amur ide was sequenced using the Illumina platform and assembled into 53,632 cDNA contigs, with an average length of 647 bp and a N50 length of 1,094 bp. A total of 19,338 unique proteins were identified, and gene ontology and KEGG (Kyoto Encyclopedia of Genes and Genomes) analyses classified all contigs into functional categories. Open Reading Frames (ORFs) were detected from 34,888 (65.1%) of contigs with an average length of 577 bp, while 9,638 full-length cDNAs were identified. Comparative analyses revealed that 31,790 (59.3%) contigs have a significant similarity to zebrafish proteins, and 27,096 (50.5%), 27,524 (51.3%) and 27,996 (52.2%) to teraodon, medaka and three- spined stickleback proteins, respectively. -

Mercury content was higher in the muscles than other organs in both species (p < 0.05). Mercury accumulates along the food chain of the lake’s ecosystem. The value of the bioconcentration factor (BCF) indicated that Hg had accumulated in the highest amounts in muscles and in the other organs as follows: muscles > liver > gills > gonads. -
Coastal Fisheries in the Eastern Baltic Sea (Gulf of Finland) and Its Basin from the 15 to the Early 20Th Centuries
Coastal Fisheries in the Eastern Baltic Sea (Gulf of Finland) and Its Basin from the 15 to the Early 20th Centuries Julia Lajus1,2, Alexei Kraikovski2, Dmitry Lajus3* 1 National Research University Higher School of Economics, St. Petersburg, Russia, 2 European University at St. Petersburg, St. Petersburg, Russia, 3 St. Petersburg State University, St. Petersburg, Russia Abstract The paper describes and analyzes original data, extracted from historical documents and scientific surveys, related to Russian fisheries in the southeastern part of the Gulf of Finland and its inflowing rivers during the 15- early 20th centuries. The data allow tracing key trends in fisheries development and in the abundance of major commercial species. In particular, results showed that, over time, the main fishing areas moved from the middle part of rivers downstream towards and onto the coastal sea. Changes in fishing patterns were closely interrelated with changes in the abundance of exploited fish. Anadromous species, such as Atlantic sturgeon, Atlantic salmon, brown trout, whitefish, vimba bream, smelt, lamprey, and catadromous eel were the most important commercial fish in the area because they were abundant, had high commercial value and were easily available for fishing in rivers. Due to intensive exploitation and other human-induced factors, populations of most of these species had declined notably by the early 20th century and have now lost commercial significance. The last sturgeon was caught in 1996, and today only smelt and lamprey support small commercial fisheries. According to historical sources, catches of freshwater species such as roach, ide, pike, perch, ruffe and burbot regularly occurred, in some areas exceeding half of the total catch, but they were not as important as migrating fish and no clear trends in abundance are apparent. -
History Characteristics of Ide Leuciscus Idus in the Eastern Baltic Sea M
Fisheries Management and Ecology Fisheries Management and Ecology, 2015 Life-history characteristics of ide Leuciscus idus in the Eastern Baltic Sea M. ROHTLA, R. SVIRGSDEN, I. TAAL, L. SAKS, R. ESCHBAUM & M. VETEMAA Estonian Marine Institute, University of Tartu, Tartu, Estonia Abstract Otolith Sr:Ca and Ba:Ca profiles were used in parallel with age data to investigate the life-history characteristics of ide, Leuciscus idus (L.) (n = 111), in the V€ainameri Sea, West Estonia. Sr:Ca profiles were more variable and useful than Ba:Ca profiles. Flexible life-history patterns were observed within and among the three study sites. Most of the individuals (72%) hatched in semi-enclosed bays that are fresh water during spring spawning but are often flooded with brackish water during other seasons. The importance of lotic spawning varied among sites and was the highest (88%) in Matsalu Bay, moderate in Saunja Bay (33%) and lowest (0%) in K€aina Bay. Young of the year emigrated from natal sites and entered the sea within the first summer; 95% did so during the first month post- hatch. Juvenile ide undertook non-spawning, freshwater migrations in the following spring; however, the reasons behind this phenomenon remain unknown. As the importance of lotic spawning has significantly decreased and multiple historically important ide spawning rivers lack anadromous runs altogether, it is suggested that actions should be taken to aid the recovery of those imperilled spawning stocks.

(Perciformes: Percidae), and redescription of Phyllodistomum macrocotyle (Lühe, 1909) with notes on the species diversity and host specifcity in the European Phyllodistomum spp. (Trematoda: Gorgoderidae) Romualda Petkevičiūtė1*, Alexander E. Zhokhov2, Virmantas Stunžėnas1, Larisa G. Poddubnaya2 and Gražina St anevičiūtė1 Abstract Background: European species of the large genus Phyllodistomum Braun, 1899 had historically been erected based solely on morphological characters. Unfortunately, many of them are still poorly known and inadequately described. Molecular approaches are critical to delineate species which were impossible to diferentiate based on morphology alone. Methods: New samples of adult Phyllodistomum spp. were collected from the urinary bladder and/or ureters of Euro- pean freshwater fshes and fxed to conduct a light and scanning electron microscopy study, and to obtain sequences of nuclear (ITS2 spacer and 28S rRNA gene), to be analysed in the context of a molecular phylogeny. Results: Based on new fndings, a new species of Phyllodistomum from the urinary bladder of the European perch, Perca fuviatilis, in Volga River basin, Russia, is described. Additionally, new data on the morphology and tegumental surface topography of P. macrocotyle (Lühe, 1909) Odhner, 1911 from ureters of the common rudd, Scardinius eryth- rophthalmus, is presented. The host range of P. folium, confrmed by DNA analysis, is extended to other cyprinid fsh species. Conclusions: The present study has again shown that species of the genus Phyllodistomum are in dire need of revision based on both molecular analysis and detailed morphological redescriptions of the forms attributed to the genus. -
Detection of Koi Herpes Virus (KHV) Genome in Apparently Healthy Fish

Meyer3, D. Schrudde1 and J. Kempter2 1 Friedrich-Loeffler-Institut, Federal Research Institute for Animal Health, Institute of Infectology, Südufer 10, 17493 Greifswald-Insel Riems, Germany; 2 Agricultural University, Department of Aquaculture, K. Królewicza4, 71-550 Szczecin, Poland; 3 Veterinary High school, Hannover, Bünteweg 17, 30559 Hannover, Germany Abstract Koi herpesvirus (KHV) induces a lethal disease in species belonging to Cyprinus carpio, covering common carp and koi or fancy carp. To date, other cyprinid fish species kept together with KHV infected carp or koi, such as goldfish (Carassius auratus) or grass carp (Ctenopharyngodon idella) had never shown any sign of KHV infection. Unexplainable outbreaks of KHV infection in common carp or koi led to the suspicion that more disease influencing factors exist, than so far explained. In challenge experiments and by natural routes of infection, it has been demonstrated that naive carp or koi can be infected by the following mechanisms; exposure to water from severe KHV diseased fish, co-habitation with KHV infected carp, by injection or immersion with cell supernatant of KHV infected cultures. Experiments were conducted to determine if apparently healthy koi (carriers/ survivors) or non-Cyprinus carpio species stocked with KHV infected carp could become infected. The study proved that these species were able to transfer KHV to naïve carp. As a result scientists suspected that some ornamental fish species could act as reservoirs of KHV infection. -

Advancing Improvement in Riverine Water Quality Caused a Non-Native Fish Species Invasion and Native Fish Fauna Recovery
www.nature.com/scientificreports OPEN Advancing improvement in riverine water quality caused a non‑native fsh species invasion and native fsh fauna recovery Łukasz Głowacki*, Andrzej Kruk & Tadeusz Penczak The knowledge of biotic and abiotic drivers that put non‑native invasive fshes at a disadvantage to native ones is necessary for suppressing invasions, but the knowledge is scarce, particularly when abiotic changes are fast. In this study, we increased this knowledge by an analysis of the biomass of most harmful Prussian carp Carassius gibelio in a river reviving from biological degradation. The species’ invasion followed by the invasion’s reversal occurred over only two decades and were documented by frequent monitoring of fsh biomass and water quality. An initial moderate improvement in water quality was an environmental flter that enabled Prussian carp’s invasion but prevented the expansion of other species. A later substantial improvement stimulated native species’ colonization of the river, and made one rheophil, ide Leuciscus idus, a signifcant Prussian carp’s replacer. The redundancy analysis (RDA) of the dependence of changes in the biomass of fsh species on water quality factors indicated that Prussian carp and ide responded in a signifcantly opposite way to changes in water quality in the river over the study period. However, the dependence of Prussian carp biomass on ide biomass, as indicated by regression analysis and analysis of species traits, suggests that the ecomorphological similarity of both species might have produced interference competition that contributed to Prussian carp’s decline. Non-native species are a major driver of the biotic homogenization and loss of biodiversity of freshwater ecosystems1–3. -
Ammonia and Nitrite Acute Toxicity in Juvenile Piavuçu Leporinus Macrocephalus (Actinopterygii, Anostomidae)
Ammonia and nitrite acute toxicity in juvenile piavuçu Leporinus macrocephalus (Actinopterygii, Anostomidae) DANIEL DE SÁ BRITTO PINTO1, LUCAS CAMPOS MALTEZ1*,GIOVANNA RODRIGUES STRINGHETTA1, LUCAS PELLEGRIN1, LILIAN FIORI NITZ1, MARIO ROBERTO CHIM FIGUEIREDO1 & LUCIANO DE OLIVEIRA GARCIA1 1Universidade Federal do Rio Grande (FURG), Instituto de Oceanografia (IO), Laboratório de Aquicultura Continental (LAC), BR 392 Km 21, Rio Grande, RS, Brazil. *Corresponding author: [email protected] Abstract: The present study aimed to evaluate the acute toxicity of non-ionized ammonia (NH3) - and nitrite (NO2 ) in piavuçu Leporinus macrocephalus juveniles. Two trials (96 h) were performed in 7 L aquaria (6 fish/aquarium), in semi-static systems, with 3 replicates per treatment. On the first trial, the juvenile piavuçu (3.0 ± 0.3 g) were exposed to 7 concentrations -1 of non-ionized ammonia (control; 0.36; 1.85; 2.43; 2.80; 3.50 and 4.86 mg NH3-N L ). On the second trial, fish (6.7 ± 0.4 g) were exposed to 6 different nitrite concentrations (control; 80.00; - -1 101.00; 120.50; 138.20 and 155.60 mg NO2 -N L ). Mortality was recorded every 24 h and the lethal concentration (LC50) was calculated by the Spearman-Karber method. The estimated LC50 -1 of non-ionized ammonia was 3.1, 2.9, 2.5 and 1.9 mg NH3-N L at 24, 48, 72 and 96 h, - -1 respectively. For nitrite, the estimated values were 130.0, 116.2, 105.8 and 94.4 mg NO2 -N L at 24, 48, 72 and 96 h, respectively. The estimated safe level for non-ionized ammonia was 0.19 -1 - -1 mg NH3-N L , while for nitrite was 9.44 mg NO2 -N L .Visual clinical signs of intoxication with ammonia (hyperexcitability, hyperventilation, erratic swimming, loss of equilibrium, lethargy and coma) and nitrite (hyperventilation and lethargy) were described throughout the experiment.
