Abstract The restoration of fish passage has been focused on anadromous species, whilst studies accommodating coarse species have often considered incidental, yet frequently these are the predominant group encountered in rivers. In addition, fishway designs depend greatly interplay between hydraulics and biomechanics, very little data available responses to specific hydraulic settings for species. This study aims explore effects water velocity turbulence behaviour a cyprinid ‐ Iberian barbel...
Summary Freshwater systems are severely impacted by connectivity reduction due to the construction of dams and weirs. The breach this longitudinal imperils freshwater fish species world‐wide. There is thus an increasing need for numerical tools that help decision‐makers correctly allocate resources prioritize restoration actions. This study provides a methodology prioritizing removal barriers. It based on spatial graphs, which represent structural units as nodes relationships between links,...
Rivers are experiencing increasing anthropogenic pressures and salinity has shown to affect freshwater fish behaviour, potentially disrupting ecological processes. In this study, the aim was determine sub-lethal effects of salinization on using a widespread native cyprinid species, Iberian barbel (Luciobarbus bocagei) as model species. Behavioural trials in mesocosms setting were performed assess three levels gradient - control (no salt added water, 0.8 mS/cm), low (9 high concentration (18...
Fish are particularly sensitive to connectivity loss as their ability reach spawning grounds is seriously affected. The most common way circumvent a barrier longitudinal connectivity, and mitigate its impacts, implement fish passage device. However, these structures often non-effective for species with different morphological ecological characteristics so there need determine optimum dimensioning values hydraulic parameters. aim of this work study the behaviour performance two (Iberian...
Throughout the world, emerging barriers in river systems block longitudinal connectivity for migrating fish, causing significant impacts by precluding them from carrying out vital life cycle activities. Fishways are still main mitigation solution implemented, where barrier removal is not feasible. Within multiple technical fish passage devices, vertical slot fishway (VSF) considered most reliable. Early design guidelines, established cyprinids, indicate that volumetric dissipation power (Pv)...
1. Over the last decade development of small hydropower projects has been one most active areas energy sector. One main environmental challenges faced by such is related to fish passage. 2. The impact 18 plants (SHPs) with distinct levels fish-pass effectiveness was investigated in summers 1998 and 1999 comparing assemblage composition structure at 36 sites, above below SHPs. 3. With regard effectiveness, it estimated that eight (44.4%) surveyed passage facilities were suitable for target...
Summary 1. Reliable lotic ecological monitoring requires knowledge of river typology, environmental factors, the effect stressors known here as ‘pressures’ and appropriate indicators anthropogenically induced change. We sampled benthic macroinvertebrate, fish, bird macrophyte communities along an intermittent Mediterranean analysed community structure (relative abundance) function (metrics) relative to pressure gradients in order identify suitable indicator group(s) for future mitigation...
The presence of small weirs, far more numerous than dams, has increased habitat fragmentation on rivers worldwide. This study aims to evaluate the upstream passage performance a potamodromous cyprinid, Iberian barbel (Luciobarbus bocagei), over an experimental broad-crested weir by varying key-hydraulic parameters. Fish success was studied for different combinations waterfall height (Δh), plunge pool depth (D) and flow discharge (Q). pattern downstream characterized with 3D Acoustic Doppler...
Research on how intermittent water releases from hydropower plants affect the early life stages of fish has advanced in last years, focusing not only direct impacts rapid flow changes (hydropeaking), but also short-term fluctuations temperature (thermopeaking). Flow and thermal caused by hydropeaking may movement patterns migration at critical a species' cycle, e.g., inducing passive downstream drift. Using two experimental outdoor channels, we investigated nase (Chondrostoma nasus,...
Introdução: A sífilis adquirida é uma doença infecciosa causada pelo patógeno Treponema pallidum. Sua transmissibilidade ocorre através de transfusões sanguíneas e relações sexuais desprotegidas, caracterizando essa enfermidade como Infecção Sexualmente Transmissível (IST). Apesar ser curável, sua evolução sem tratamento adequado pode levar a complicações sistêmicas graves, cardiovascular neurossífilis. Estudar o perfil epidemiológico da fundamental, especialmente em regiões Rondônia, onde...
Biodiversity assessments at the river basin level represent a crucial step in drawing conservation strategies for freshwater biota. As basins are independent functional units, it is fundamental to ensure that spatial information on species presence fitted where they effectively occur. To maximize quality and fitness data usage, scientific names recorded during fish sampling, which may be outdated (synonyms), need associated with currently accepted names. The RivFISH database shows of all...
Objective: The objective of this study is to evaluate the quality drainage water from a saline-sodic soil at different collection points and times regarding its use for irrigation. Theoretical Framework: research based on guidelines characterizing irrigation according University California Committee Consultants, adapted by Ayers Westcot (1994).
