Improving eel pass efficiency: The role of crest shape and water flow in facilitating upstream juvenile eel migration

Journal of Fish Biology, EarlyView.
Abstract River connectivity is crucial for the European eel (Anguilla anguilla) to complete its complex life cycle, which is vital for upstream recruitment to the declining population of this critically endangered catadromous fish. Eel passes, or ladders, are frequently installed on riverine structures, such as dams and weirs, to mitigate barrier ...

TECHNOLOGICAL ASPECTS REGARDING REARING OF THE ACIPENSER RUTHENUS SPECIES, ALBINO VARIETY TO SECOND SUMMER OLD, IN BRATES STURGEONS STATION

Scientific Papers Animal Science and Biotechnologies, 2023
The Acipenser ruthenus (Linnaeus, 1758), albino variety, in the second summer rearing to Brates sturgeons station from Galati was experimented. A number of 513 one year old sterlet were stocked in three Ewos fibreglass tanks, at an individual mean weight

Acclimation conditions and subsequent acute hypoxia challenges do not affect the frequency of erythrocyte nuclear segmentation in triploid brook charr Salvelinus fontinalis (Mitchill 1814)

Journal of Fish Biology, EarlyView.
Abstract Routine observations of blood smears have repeatedly shown that triploid fish have a greater proportion of erythrocytes with nuclear segmentation (ENS) than diploids; however, there is as yet no understanding of why this is the case and whether it affects erythrocyte function.

Testing non‐lethal techniques for endoparasite detection and sex determination in pumpkinseed sunfish (Lepomis gibbosus)

Journal of Fish Biology, EarlyView.
Abstract Developing non‐lethal techniques to estimate parasite infection is critical for studying disease ecology in wild animals. We tested the effectiveness of coelomic ultrasonographic examination and plasma enzyme markers to detect liver infection with bass tapeworms Proteocephalus ambloplitis (Leidy 1887) as well as the effectiveness of ultrasound

Non‐invasive ultrasound measurements for determination of hepato‐somatic index in Greenland halibut (Reinhardtius hippoglossoides)

Journal of Fish Biology, EarlyView.
Abstract Hepato‐somatic index (HSI) is widely used to indicate fish body condition and level of energy reserves related to feeding/physiology and reproduction. HSI is traditionally obtained by dissection and measurement of liver mass versus body mass, but ultrasound technology may provide a minor invasive method to obtain liver dimensions to estimate ...

Structure and composition of yellowtail kingfish (Seriola lalandi) otoliths: implications for using aquaculture‐reared fish to reconstruct life histories

Journal of Fish Biology, EarlyView.
Abstract Understanding fish life history is essential for effective management of fisheries, but continuous tracking over lifetime temporal scales can be difficult. Fish otoliths contain a natural biogeochemical record of ambient environmental conditions and habitat use over such scales.

Expression of corticoid‐regulatory genes in the gills of Atlantic salmon (Salmo salar) parr and smolt and during salinity acclimation

Journal of Fish Biology, EarlyView.
Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...
