Lucrarea de față reprezintă rezultatele cercetărilor ihtiofaunei fluviului Nistru în anii studii 2020-2023. Este evidențiată importanța protecției tronsonului situat ava barajul Dubăsari, fiind o zonă deosebit sensibilă caracterizată mare diversitate ihtiofaunistică, unde se află vaste boiși ale speciilor litofile și psamofile pești. De asemenea au fost analizate loturile reproductive speciei Alosa immaculata din punct vedere al intensității migrației fl. gradului încărcare parazitară.În...
Lucrarea de față reprezintă rezultatele elaborării și modernizării metodologiei reproducerii natural-dirijate a speciilor vulnerabile pești, după exemplul linului Tinca tinca, Linnnaeus, 1758. S-a demonstrat eficiența mai mare utilizare reproducătorilor domesticiți în comparație cu cei capturați nemijlocit înaintea perioadei reproducere naturală. Cea probabilă cauză dereglare comportării reproductive la loturile sălbatice este influența stresului produs procesul capturare, transportare,...
În lucrarea de față se analizează dinamica diversității ihtiofaunei râului Prut, afluent al fluviului Dunărea. Investigațiile efectuate în ecosistemul menționat au scos evidență o diversitate ihtiofaunistică constituită din 62 specii, atribuite la 13 ordine și 22 familii. Se constată că efectele schimbărilor climatice, exprimate prin secete lungă durată urmate inundații masive pe arii extinse provoacă răspândirea mai activă a speciilor pești diverse zone piscicole cadrul bazinului...
Based on the multi-annual studies conducted in aquatic ecosystems of Republic Moldova, have been developed scientific and practical recommendations regarding prevention reduction active eutrophication phenomenon country. One environmentally friendly method, economicaly efficient advantageous is use macrophytophagous restorative phytoplanktonophagous fish species.
This paper presents the most important recommendations for combating of pisciculous invasions in aquatic ecosystems Republic Moldova context increasing threats to indigenous fish species.There are exposed concrete actions on monitoring, prevention and biological pollution with allogenic species hydrobionts, which will serve as a methodological scientific basis implementation National Program ivasions.
At present, particular attention is paid to large rivers without realizing that the ecological status of a lotic ecosystem depends on state its tributaries. Thus, in conditions growing anthropogenic presetting, we aimed demonstrate importance ecotone zones formed between two riparian ecosystems different sizes, order ensure welfare fish resources both sides.
The purpose of this paper is to analyze the taxonomic structure and ecological indices fish communities in two types aquatic ecosystems separated by Dubasari Dam. carried out research revealed a richer specific diversity significantly higher quantitative values fishing downstream area hydro power plant. decisive factor fragmentation Dniester River, causing interruption reproductive, trophic winter migration reobionticfish species.
The paper presents the results of scientific research and ichthyological observations on Costesti-Stanca reservoir from succesional point view. It is first review state ichthyofauna this ecosystem since its formation. Along time, registered number fish species has increased 22 to 34. In years after filling up (1980), catches were numerically dominated by perch – 46.5%, common roach silver crucian carp with 8.7% each. Due systematic populations economically valuable (carp, pikeperch bream),...
The populations of most fish species in the Republic Moldova reproduce naturally, however, as a result increasing anthropogenic impact on aquatic ecosystems, conditions for their natural reproduction have deteriorated significantly. In this context, one research objectives 2020 was development efficient technological principles conservation and rational use local stock. It revealed ensuring vulnerable stages ontogenesis controlled environmental is basic productivity management Danube...
The present work presents the results of research ichthyofauna largest accumulation lakes in Republic Moldova (Dubăsari on Dniester River and CosteștiStânca Prut River) under conditions climate changes intensification anthropogenic pressure. state profound change ichthyocenosis Dubasari reservoir is demonstrated, which currently dominated by small species (gobius species, bleak, bitterling, blackstriped pipefish), indicates urgent need to carry out ameliorating measures populating ecosystems...
