Abstract European grayling populations have declined significantly in their central range, prompting numerous stocking programs with reared fish that did not bring desirable population prosperity. This study evaluated the effectiveness of long‐reared brood before spawning period. It focused on monitoring presence juveniles coming from natural spawn stream and recapture rates growth parameters stocked to estimate adaptability a river environment. The results revealed rate was notably low,...
This study investigated how 2+-year-old stocked pond-reared European graylings ( Thymallus thymallus ) acclimatised to a wild environment during six months (May–October 2019) after released. We examined the quantity and composition of lipids in liver, muscles visceral adipose tissues (VAT), as well size parameters, condition factors stomach contents. Our results showed low post-stocking recapture rate (5.17%) fish 6 suggesting poor acclimation environment. During monitoring, fishes exhibited...
Pharmaceutical pollution represents a rapidly growing threat to ecosystems worldwide. Drugs are now commonly detected in the tissues of wildlife and have potential alter natural expression behavior, though relatively little is known about how pharmaceuticals impact predator-prey interactions. We conducted parallel laboratory experiments using larval odonates (dragonfly damselfly nymphs) investigate effects exposure two pharmaceuticals, cetirizine citalopram, their mixture on outcomes found...
Fry of rainbow trout, Oncorhynchus mykiss (Walbaum, 1792), was subjected to one-hour and four hours immersion in Alizarin red S (ARS) bath 150 mg · L –1 . The experiment involved seven age groups (40, 50, 60, 70, 80, 90, 100 days) conducted estimate the minimal salmonids for mass marking with ARS enabling subsequent effective, simple field nonlethal identification, based on fin rays checking. fish were examined at ages 200 300 days. results showed a high retention level traces caudal ensured...
European grayling, Thymallus thymallus (Linnaeus, 1758) (Actinopterygii: Salmoniformes: Salmonidae), represents one of the highly attractive riverine fishing species in Europe. Its populations have declined Czech Republic due to various adverse factors. Current approaches for strengthening these based on restocking with artificially reared 1+ or 2+ old individuals proven be ineffective. This study focuses possibilities supporting restoring by reintroducing two-month-old, fast-growing fry...
