Concepts of spawning targets [PDF]
, 2000 This report discusses the concepts of spawning targets. Spawning target setting is based on the fact that the number of smolts produced by any given river is constrained by habitat availability.

Australian Veterinary Journal, EarlyView.Barramundi (Lates calcarifer) is an economically significant aquaculture species and ranks among Australia's top five farmed finfish. As global production intensifies, understanding the physiology and health of barramundi is essential to support animal welfare and industry profitability.

Potential Impact of Climate Change on Salmonid Smolt Ecology
Fishes, 2023 The migratory life history of anadromous salmonids requires successful migration between nursery, feeding, and spawning habitats. Smolting is the major transformation anadromous salmonids undergo before migration to feeding areas.

Enumerating Atlantic salmon smolt production in River Vindelälven based on habitat availability and parr densities : consequences of using different density estimation methods [PDF]
, 2010 Habitat mapping was conducted in the main stem of River Vindelälven in the autumn of 2009 along the salmon distribution area. The aim was to estimate the quantity of potential reproduction areas, including spawning and juvenile rearing habitats.

Worldwide Invasions of Centrarchidae: The Dark Side of the Sunfish Family
Fish and Fisheries, EarlyView.ABSTRACT Freshwater fish invasions are major drivers of global ecological change, disrupting native biodiversity and ecosystem functions. However, many invasive fish hold significant socioeconomic value, resulting in conflict over their management. Centrarchidae, which are globally distributed and are important for sportfishing and aquaculture, are now

Fisheries Management and Ecology, EarlyView.ABSTRACT The global decline in salmonid stocks has increased the need for knowledge of local adaptations and life history strategies of salmonids. In this study, we used radio‐telemetry tracking data from sea trout populations in two large high‐latitude rivers to model upstream spawning migration speed of trout in response to prevailing environmental ...

The relationship between smolt and postsmolt growth for Atlantic salmon (Salmo salar) in the Gulf of St. Lawrence [PDF]
, 2006 The interaction of ocean climate and growth conditions during the postsmolt phase is emerging as the primary hypothesis to explain patterns of adult recruitment for individual stocks and stock complexes of Atlantic salmon (Salmo salar). Friedland et al. (

Genetic and Ecological Management of Pacific Salmon Fisheries for the 21st Century
Fisheries Management and Ecology, EarlyView.ABSTRACT Based on ecological adaptation theory, tremendous effort is being spent on measures that are eliminating salmon hatcheries and fishing opportunities with the intention of protecting wild runs deemed to be of particular genetic importance to the survival of the species.
