Cellular and molecular evidence for a role of tumor necrosis factor alpha in the ovulatory mechanism of trout [PDF]
, 2010 Background: The relevance of immune-endocrine interactions to the regulation of ovarian function in teleosts is virtually unexplored. As part of the innate immune response during infection, a number of cytokines such as tumor necrosis factor alpha (TNF ...

Prevalence and Implications of “Must‐Kill” Angling Regulations for the Management of Invasive Fishes
Fisheries Management and Ecology, EarlyView.ABSTRACT Freshwater biodiversity is increasingly threatened by invasive species, which can disrupt native fish populations and the fisheries they support. Must‐kill regulations, which prohibit the live release of invasive fish caught by recreational anglers, are a management strategy that can be implemented to limit the negative effects of invasive ...

Effects of stocked trout on stream invertebrate communities
Journal of Freshwater Ecology, 2017 Brown trout (Salmo trutta) are commonly stocked in streams and rivers worldwide to enhance recreational fisheries, but this practice can adversely impact other organisms in these ecosystems.

Optimal flow for brown trout: Habitat – prey optimization [PDF]
Science of The Total Environment, 2016 The correct definition of ecosystem needs is essential in order to guide policy and management strategies to optimize the increasing use of freshwater by human activities. Commonly, the assessment of the optimal or minimum flow rates needed to preserve ecosystem functionality has been done by habitat-based models that define a relationship between in ...

Some observations on washout of brown trout (Salmo trutta L.) eggs in Teesdale streams [PDF]
, 1981 Brown trout (Salmo trutta) in Teesdale lay their eggs in the streambed gravels in the Autumn, here the eggs slowly develop to emerge as young fry in the Spring.

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 ...
