Effects of temperature and browning on the functional response of a freshwater top predator
Journal of Animal Ecology, Volume 95, Issue 5, Page 824-836, May 2026.This study explores for the first time how temperature and browning affect the functional response of a freshwater piscivore, the northern pike. The authors find surprisingly weak effects of browning, challenging visual foraging theory. Pike displayed a rare dome‐shaped functional response in cold clear water, potentially driven by seasonal changes in ...

Fish and Fisheries, Volume 27, Issue 3, Page 431-450, May 2026.ABSTRACT Hatcheries and stocking programmes have long been a cornerstone of fisheries management, seen as tools for fisheries enhancement and/or conservation of threatened populations. Their use draws controversy, however, from a growing body of research over the last 50 years suggesting that stocking can have negative consequences for wild stocks, and

Fish and Fisheries, Volume 27, Issue 3, Page 478-495, May 2026.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 ...

Aspects of the washout of salmonid eggs. 4. Effects of a standard mechanical shock, applied at different stage of development, upon survival and development of eggs of brown trout (Salmo trutta L.) [PDF]
, 1985 It is generally accepted by fish culturists that salmonid eggs are sensitive to mechanical shock and that the sensitivity varies with the stage of development of the eggs.

Egyptian Academic Journal of Biological Sciences, B. Zoology, 2013 16S rRNA gene in the salmo trutta fario and Salmo trutta caspius has been polymerized, characterized and compared with within and between of salmonids species. The full lengths of 16S rRNA gene in species of salmons were sequenced approximately 1.7 kb and deposited in GenBank. We designed one pair of primer for amplification of 16S rRNA gene in species
