Abstract Acoustic telemetry data often contain erroneous detections, which need to be addressed before further analysis. It is important that this process systematic, standardised and reproducible. The r package actel provides a systematic conditional pipeline filter analyse acoustic in reproducible fashion, for animals moving between receiver arrays. outputs report containing the main results steps taken by user, addition summary information each animal other content such as efficiency...
Abstract Miniaturization and optimization of batteries electric components, as well new technological innovations, are driving increased use microelectronic tags to study animals in the wild that smaller than ever before. Here, we provide an overview different alternatives common electronic tagging tracking tools used for aquatic research discuss opportunities afforded by these micro challenges investigators. We optimistic miniaturization will create novel ecological inquiry. A key advance...
Abstract The River Bush (Northern Ireland) is an index river for the estimation of Atlantic salmon, Salmo salar L., stock size, population dynamics and marine survival rates. Marine estimates are based on number smolts counted at a trap 3.5 km upstream outlet. from release to coastal inshore waters acoustic‐tagged released Bushmills varied between 32% 68%, with both year brightness during exit playing significant role in explaining variations survival. This constitutes important bottleneck....
Kelts - individuals of anadromous fish species which have successfully spawned and may return to sea repeat the cycle are perhaps least studied life stage iteroparous species. To date, our understanding what makes them successful in their migration is limited. We investigated relationship between three physiological parameters (baseline cortisol, baseline glucose low molecular weight antioxidants) timing success Atlantic salmon (Salmo salar) trout trutta) kelt migration. do so, we combined...
Abstract Acoustic telemetry enables spatial ecologists to collect movement data from a variety of aquatic species. In estuaries and rivers, accounting for the complex shape water bodies is challenging. Current methods analysing utilization distributions (UDs) are restricted using locations receivers where animals have been detected, which limits information available estimate paths. We present new r package (RSP—Refined Shortest Paths) movements tracked with acoustic transmitters in...
Abstract The Atlantic salmon ( Salmo salar ) population of the River Minho represents southern natural distribution edge species. In line with general trend for salmon, this has been declining over years and is now at a critically low level. With river connectivity compromised by large dam just 80 km upstream Minho's outlet, an expected deterioration climatic conditions, it urgent to increase our knowledge identify survival bottlenecks that can be addressed. study, we used radio acoustic...
Targeted sequencing is an increasingly popular next-generation (NGS) approach for studying populations that involves focusing efforts on specific parts of the genome a species interest. Methodologies and tools designing targeted baits are scarce but in high demand. Here, we present guidelines considerations capture experiments population genetics both neutral genomic regions subject to selection. We describe bait design process three diverse fish species: Atlantic salmon, cod tiger shark,...
Abstract The survival rates of three groups seaward‐migrating Salmo salar smolts were investigated in 2005, 2016, and 2017 the River Skjern Omme, as well Ringkøbing Fjord using acoustic telemetry. extends for approximately 300 km 2 , has a narrow, regulated outlet to sea. Smolts different origins: (a) wild smolts, (b) hatchery‐reared previously released at half‐year‐old, (c) 1‐year‐old captured rotary screw traps surgically implanted with transmitters. progress during seaward migration was...
Estuaries are complex environments that provide important nursery areas for several fish species, but anthropogenic activities as well low salinities may affect reproductive potential. This study investigated spawning migrations of turbot (Scophthalmus maximus) and European flounder (Platichthys flesus) in the estuary Roskilde Fjord using acoustic telemetry. For turbot, migratory behaviour was coupled with salinity measurements to estimate likelihood successful spawning. Turbot inRoskilde...
ABSTRACT Counting departing smolts and returning adults in index rivers is essential to estimate marine survival track population trends of Atlantic salmon ( Salmo salar ). However, mortalities between counting facilities a river mouth can skew estimates. We used acoustic radio telemetry investigate survival, mortality sources behaviour wild the River Erriff, Ireland's river, Killary Fjord. Smolts were tagged with tags 2017 n = 40) 2018 35) 30). Survival was low for acoustic‐tagged (26%)...
Abstract Many coastal ecosystems are impacted by human pressures. Rocky reefs structurally complex habitats that often support elevated fish abundance and marine biodiversity. In the Baltic Sea, rocky have suffered from extraction for decades, leading to a decrease in hard substrata habitat availability. This study is first restore cobble examine biological effects. Baited unbaited underwater video systems (BRUVS UBRUVS, respectively) were employed across five years monitor communities...
