Effects of temperature and browning on the functional response of a freshwater top predator

Journal of Animal Ecology, EarlyView.
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 ...

Using structured decision making to evaluate the tradeoffs of selective fish passage

Conservation Science and Practice, EarlyView.
Abstract Dams have dramatically altered rivers and are a major contributor to native fish population declines. However, many dams serve important ecological, social, and economic functions, such as flood control, invasive species control, and provision of recreational opportunities.

A Review of a Decade of Anadromous Salmonid Hatchery (And Stocking) Research: Insights for Policy, Management and a Changing Climate

Fish and Fisheries, EarlyView.
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

A Meta‐Analysis on Environmental Triggers of Spawning Migrations Reveals a New Classification of Thermal Guilds in European Freshwater Fishes

Fish and Fisheries, EarlyView.
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 ...

Morphometric and External Injury Characterization of Rainbow Trout (O. mykiss) Used for Stocking in the Alpine River Inn (Bavaria, Germany)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Stocking fish is a common practice in fisheries management, particularly for species of high conservation value or economic importance. Despite its widespread use, systematic evaluation of fish stockings remains scarce. This includes non‐native species such as rainbow trout (Oncorhynchus mykiss), which are intensively stocked into European ...
