Приведены результаты исследования видового состава ихтиофауны р. Ахурян до и после малой гидроэлектростанции (МГЭС) «Амасия», проведенного в 2018–2019 гг. Отмечено 12 видов рыб. Впервые изучение рыб было проведено с помощью электролова. Наибольшее число (7) зафиксировано весной 2019 г. нижнем течении реки у пос. Мармашен, наименьшее (3 вида) – осенью 2018 года на участках отбора проб вблизи МГЭС «Амасия» водозабора притоке Ахурян. На всех станциях вылова были отмечены восточная быстрянка...
The effect of 96 h exposure the goldfish Carassius auratus to two different types bioplastic particles, originating from commercial shopping bag (Bag, ~5 mm) and polylactic acid-based (PLA) cup (Cup, ≤5 mm), petroleum-based polyamide particles (PA, 0–180 µm) was studied. All were studied as virgin after simulated UV-degradation (at concentration 30 mg L−1). experiments conducted according OECD 203 test guidelines. toxicity endpoint evaluated in fish brain gills lipid peroxidation (LPO)...
Harmful algal blooms (HABs) are overgrowths of toxic strains algae (diatoms, green) and cyanobacteria (blue-green algae). While occurring naturally, human-induced environmental changes have resulted in more frequent occurrences such worldwide. Meantime, the ecotoxicological risk HABs is rarely evaluated by means standard test methods. For first time, genotoxic potential HAB event 2020 was assessed using two different Tradescantia-based systems (Trad-SHM Trad-MN, 24-h exposure). An integrated...

The mitochondrial genomes from two individuals of the extinct subspecies Sevan trout Salmo ischchan danilewskii are published in this paper. DNA (mtDNA) is 16,665 base pairs (bp) length and contained 13 protein-coding genes, 2 rRNA 22 tRNA genes. overall composition genome descending order was 27.9% A, 29.4% C, 16.7% G, 26.0% T without a significant AT bias 53.9%.
The endangered endemic species Sevan trout (Salmo ischchan Kessler, 1877) is under the threat of extinction and its survival dependent on restocking by smolts. Thus, there an urgent need to find effective solution for wild populations. After developing a theoretical methodology reveal most suitable parts spawning rivers natural reproduction, we consider incubation eggs in as appropriate method validation results assessment. estimate eggs’ differences microcosm conditions which found...
The Soviet Union played the leading role in fish introductions Eurasia. However, only 3% of all prior to 1978 gave a commercial benefit. One noteworthy examples appears be Sevan trout (Salmo ischchan Kessler, 1877)-an endemic salmonid Lake Armenia. This species has been introduced Kirghizstan, Kazakhstan, and Uzbekistan, however, Kirghiz population persisted relatively high numbers. In this paper we provide first extensive molecular study S. using samples from native three hatcheries...
