Sprat spawning in two fjord areas of western Norway in 1982 and 1983 [PDF]
, 1984 A southern and a northern fjord at Western Norway were surveyed for sprat spawning from the end of May until July, six times in 1982 and four times in 1983. Sprat spawned in both areas and the surveys covered just a part of the spawning season.

River Research and Applications, EarlyView.ABSTRACT Relieving barriers and increasing free flowing rivers is a global imperative to restore habitat connectivity for migratory fish stocks. While reducing river fragmentation will certainly improve biodiversity, the spread of non‐native species throughout a river system may be facilitated as an inadvertent outcome.

White sturgeon spawning areas in the Lower Snake River
, 2000 We documented 17 white sturgeon Acipenser transmontanus spawning locations in the Snake River from the mouth to Lower Granite Dam (river km 0 to 173). Spawning locations were determined by the collection of fertilized eggs on artificial substrates or in ...

River Research and Applications, EarlyView.ABSTRACT The presumptive standards approach to environmental flows offers a method to develop interim guidelines for ecological and social‐cultural flow needs. The approach is based on deriving acceptable percent‐of‐flow limits based on naturalised flows (the absence of depletion or alteration of flow), and it can be an effective precursor to a full ...

The Role of Sediment Supply on Fish Habitat Dynamics of a Morphologically Active River Widening
River Research and Applications, EarlyView.ABSTRACT Restoration measures, such as river widening, aim to reactivate key morphodynamic processes, which are critical drivers of fluvial habitat dynamics. While some evidence supports the important role of sediment supply on river widening's morphology, its link to fish habitat availability and dynamics remains unclear.

Effects of Sediment‐Control Operations on Fish and Macroinvertebrate Communities in Dam Reservoirs
River Research and Applications, EarlyView.ABSTRACT Sediments are avoided in many river and dam managements because of their adverse effects on water usage and flood control. Recently, sedimentation control measures, including sluicing, have been employed to manage sediments in river channels and restore communities in dammed rivers.

Remote Sensing in Ecology and Conservation, EarlyView.This research established a new object detection model based on YOLOv11 to recognise benthic organisms, specifically sea cucumbers, by utilising high‐resolution photogrammetric‐based orthomosaics acquired along infralittoral Mediterranean Sea beds. The model demonstrated impressive performance metrics and, when combined with the Deepness plugin for the

Cod spawning in the Borgundfjord Marine Protected Area
, 2020 The Norwegian coastal cod population north of 62°N declined in the years from 1997 to 2005 and has since remained low. The Borgundfjord has since 2009 served as an extractive Marine Protected Area (MPA) for protecting the coastal cod, as it is an important spawning ground for this threatened population.
