ABSTRACT Fish migration through river networks is essential for completing life cycles and accessing critical habitats, but fragmentation increasingly disrupts spawning movements. In Europe, over one million barriers limit connectivity and create trade‐offs between ecological integrity and human uses, such as hydropower, flood control, fisheries and ...

ABSTRACT This study aimed to quantify the cannibal‐prey size relationship using morphometric regression models and to establish an effective size‐grading strategy to prevent cannibalism. A total of 15,000 juveniles at 73 days post‐hatching (DPH) were reared in a circular tank (approximately 12 tons) operated under a flow‐through seawater system at 26.0

BIOCHEMICAL STUDIES ON SALMONIDAE II
1) The influence of the sun-light on the eggs, larvae and fry of Oncorhynchus masou (Brevoort) are studied. 2) The intensity of the sun-light may be effected already upon their chemical compositions in the fry through the oval and larval stages. The fish fed in the lighter place (in the open air out of the hatchery), as compared with the darker place ...

First Observations of Potential Iteroparity in Pacific Capelin Mallotus catervarius
ABSTRACT Using histology to examine ovarian structures in Pacific capelin for the first time, we found biological evidence that captive, age‐1, female Pacific capelin Mallotus catervarius are capable of iteroparity (41% of mature females). Evidence of the potential to spawn over multiple years included more than one oocyte cohort, including primary ...

Brown Trout Abundance in Boreal Streams With Large Wood
ABSTRACT Large wood has been found to be a crucial component in riverine ecosystems. However, due to the heavy channelization of rivers and intensive forestry practices over the past few decades, the amount of large wood in these ecosystems has decreased worldwide. River restoration aims to mitigate the effects of channelization and restore the channel

Zebrafish Tgds, when expressed as a recombinant protein, catalyzes the dehydration of UDP‐D‐glucose, the initial step in the formation of 6‐deoxyhexoses. Corresponding Tgds mutations found in Catel–Manzke syndrome patients lead to reduced enzymatic activity and stability.
