Behaviour represents a reaction to the environment as fish perceive it and is therefore a key element of fish welfare. This review summarises the main findings on how behavioural changes have been used to assess welfare in farmed fish, using both functional and feeling-based approaches. Changes in foraging behaviour, ventilatory activity, aggression,(More)
The Hydrogeomorphic (HGM) Approach for assessing wetlands was developed by the U.S. Army Corps of Engineers as a procedure for assessing the capacity of a wetland to perform ecological functions. The Approach requires classification of wetlands based on geomorphic setting, water source, and hydrodynamics. The objective of the Guidelines for Guidebook(More)
Data on canopy trees (stems ≥ 15 cm DBH) in riparian wetlands, spanning from headwaters to large river floodplains, were used to test whether forest canopy composition differed among hydrogeomorphic (HGM) riverine subclasses and among physiographic sub-regions (Major Land Resource Areas; MLRA) within a given HGM subclass. Riverine stands (n = 225) were(More)
Increased aquaculture production has raised concerns about managing protocols to safeguard the welfare of farmed fish, as consumers demand responsible aquaculture practices to provide ‘welfare friendly’ products. Feeding is one of the largest production cost in a fish farm and can be one of the biggest stressors for fish. Under farming conditions, fish are(More)
Self-feeding systems, where fish actuate a trigger to obtain food, may be a useful tool in aquaculture feed management programs as they can reduce food wastage, whilst improving growth and food conversion ratio’s. Furthermore, feeding on-demand can also reduce competition and fin damage. Fin damage (especially to the dorsal fin) can be caused by aggression,(More)
Following the development of demand-feeding systems, many experiments have been conducted to explore feeding motivation and feed intake in farmed fish. This work aims to review a selection of studies in the field, focusing on three key factors, related to demand feeding and fish welfare. Firstly, we outline how demand feeders should be considered when(More)
Historically, headwater streams received limited protection and were subjected to extensive alteration from logging, farming, mining, and development activities. Despite these alterations, headwater streams provide essential ecological functions. This study examines proxy measures of biogeochemical function across a range of catchment alterations by(More)
Fish can be the recipients of numerous injuries that are potentially deleterious to aquacultural production performance and welfare. This review will employ a systematic approach that classifies injuries in relation to specific anatomical areas of the fish and will evaluate the effects of injury upon production and welfare. The selected areas include the(More)
