However, their 14 effectiveness in larger water bodies with different fish communities in the presence of 15 natural vegetation still needs to be explored. Using a large scale field experiment with 16 twenty-four ponds stocked with differently composed fish communities, the present study 17 investigates the extent to which the effect of artificial refuges on fish is species-specific and 18 determined by the characteristics of the fish community. This study provides strong 19 experimental evidence for artificial refuges protecting fish against predation by cormorants, 20 even in the presence of submerged vegetation. The effect of the refuges was, however, 21 highly species-specific and depended on the composition of the fish community. Strong 22 positive effects of refuges on rudd and roach populations were observed, especially in ponds 23 where these species dominated from the start of the experiment. Overall, the total biomass 24 of young-of-the-year, one-year-old and adult rudd and roach was on average 500, 7 and 15 25 times lower in ponds without than in ponds with refuges, respectively. -
The Neurotoxin Β-N-Methylamino-L-Alanine (BMAA)
The neurotoxin β-N-methylamino-L-alanine (BMAA) Sources, bioaccumulation and extraction procedures Sandra Ferreira Lage ©Sandra Ferreira Lage, Stockholm University 2016 Cover image: Cyanobacteria, diatoms and dinoflagellates microscopic pictures taken by Sandra Ferreira Lage ISBN 978-91-7649-455-4 Printed in Sweden by Holmbergs, Malmö 2016 Distributor: Department of Ecology, Environment and Plant Sciences, Stockholm University “Sinto mais longe o passado, sinto a saudade mais perto.” Fernando Pessoa, 1914. Abstract β-methylamino-L-alanine (BMAA) is a neurotoxin linked to neurodegeneration, which is manifested in the devastating human diseases amyotrophic lateral sclerosis, Alzheimer’s and Parkinson’s disease. This neurotoxin is known to be produced by almost all tested species within the cyanobacterial phylum including free living as well as the symbiotic strains. The global distribution of the BMAA producers ranges from a terrestrial ecosystem on the Island of Guam in the Pacific Ocean to an aquatic ecosystem in Northern Europe, the Baltic Sea, where annually massive surface blooms occur. BMAA had been shown to accumulate in the Baltic Sea food web, with highest levels in the bottom dwelling fish-species as well as in mollusks. One of the aims of this thesis was to test the bottom-dwelling bioaccumulation hy- pothesis by using a larger number of samples allowing a statistical evaluation. Hence, a large set of fish individuals from the lake Finjasjön, were caught and the BMAA concentrations in different tissues were related to the season of catching, fish gender, total weight and species. The results reveal that fish total weight and fish species were positively correlated with BMAA concentration in the fish brain. -

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. -

animals Article Artificial Reproduction of Blue Bream (Ballerus ballerus L.) as a Conservative Method under Controlled Conditions Przemysław Piech * and Roman Kujawa Department of Ichthyology and Aquaculture, Faculty of Animal Bioengineering, University of Warmia and Mazury in Olsztyn, PL 10-719 Olsztyn, Poland; reofi[email protected] * Correspondence: [email protected] Simple Summary: Quite severe biological imbalances have been caused by the often ill-conceived and destructive actions of humans. The natural environment, with its flora and fauna, has been subjected to a strong, direct or indirect, anthropogenic impact. In consequence, the total population of wild animals has been considerably reduced, despite efforts to compensate for these errors and expand the scope of animal legal protection to include endangered species. Many animal populations on the verge of extinction have been saved. These actions are ongoing and embrace endangered species as well as those which may be threatened with extinction in the near future as a result of climate change. The changes affect economically valuable species and those of low value, whose populations are still relatively strong and stable. Pre-emptive protective actions and developing methods for the reproduction and rearing of rare species may ensure their survival when the ecological balance is upset. The blue bream is one such species which should be protected while there is still time. Abstract: The blue bream Ballerus ballerus (L.) is one of two species of the Ballerus genus occurring in Citation: Piech, P.; Kujawa, R. Europe. The biotechnology for its reproduction under controlled conditions needs to be developed to Artificial Reproduction of Blue Bream conserve its local populations. -

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.
