A global survey of 179 restoration practitioners spanning 65 countries identified the extent stakeholder engagement as a key factor determining success or failure projects. Lack support across sectors and for funding, policy, monitoring, governance knowledge assessment pressures their effects were most frequently cited factors contributing to failure. The responses indicate that, although nutrient enrichment is perceived be primary issue lakes globally, impacts climate change, hydrological modifications invasive species are widely recognized pervasive anthropogenic importance. Practitioners that ecosystem services impacted by these recreation tourism, in low income provisioning service, aquaculture, was considered impacted. Ecology-based and/or pressure-related targets had been set programs our survey. However, strength evidence underpinning often weak change rarely when setting targets. effective used measures target loading (both catchment in-lake) while implementation nature-based solutions lesser extent. Measures control non-native applied viewed being largely ineffective. results provide direction future work. New emerging pressures, singly combination, may require new approaches lake restoration: both devising strategies. depends on joined-up thinking better integrates science into policy practice and, importantly, ensures strong inclusive collaboration multiple sectors.

Freshwater bioindicators have been developed to assess ecosystem health and responses human-induced stressors. To date, most primarily rely on the species identity of plant animal communities do not account for interactions among organisms fluxes energy between trophic levels. Body size is one important ecological traits in aquatic ecosystems because it governs affected by environmental conditions but, surprisingly, many assessment approaches use individual body size. The community spectrum defined as linear relationship abundance reflects several features including carrying capacity, predation-prey interactions, fluxes. In this study, we explored potential using parameters (slope, elevation linearity) fish a complementary bioindicator 51 natural lakes 102 reservoirs distributed across France. We determined how other common based fish, macrophyte phytoplankton responded water quality degradation, littoral habitat alterations invasions. Results demonstrated that: (i) was driven degradation both reservoirs, while loss invasion (ii) more sensitive than lakes. This study highlights that could provide additional insights into our understanding freshwater global changes serve improve efficiency management programs. can be done at very limited cost commonly measured biomonitoring protocols.

Non-destructive and cost-effective fish diversity monitoring approaches are needed for the management protection of estuarine ecosystems. Environmental DNA (eDNA) technology is a promising, environmentally friendly that has been applied in studies In this study, we investigated seasonal composition, diversity, structure community Pearl River Estuary (PRE) using eDNA gillnetting. We identified 156 PRE, including 26 orders, 58 families, 93 genera, 115 species according to technology. And provided more taxonomic composition information PRE than did Significant or highly significant differences were detected between wet dry seasons. Fifteen eight genus-level indicator taxa differed significantly two seasons gillnetting, respectively. However, study suggest some not overlap approaches. Therefore, should include combination gillnetting comprehensive data analysis. Our findings have important implications ecosystem management.

Fish are an important component of aquatic ecosystems, thus representative and reliable assessments their population variables essential for a variety ecological applications, management conservation. Determining Density per actual Spatial Unit (volume or area, FDSU) as measure absolute fish quantity is particular interest. Gillnets undoubtedly one the most common methods assessing populations in large lentic waters. However, direct calculating FDSU from gillnet catches impossible because passive nature this method, to date there no model catches. This weakness largely limits use data applications requiring estimates. The aim study was calibrate using obtained by active (beach seine nets hydroacoustics) develop tool To achieve goal, we compared biomass estimated methods, both which cover similar spatiotemporal niches. comparison performed statistical approach based on recognition non-negligible random measurement error explanatory (active methods) response (gillnets) variables. We found strong positive linear relationship between biomasses sampled with gillnets methods. slope fitted when comparing two method used allowed inclusion estimates refining credible intervals relationship. effect effort accuracy simulated show how increased narrows interval. Finally, previously published relationships revealed but explainable discrepancy our previous models. Our showed that conversion spatial unit possible. effective sampling area square meter determined be 8 m2 waterbody surface European standard 12 mesh-sizes used, 5 four larger meshes added gillnets. further stressed impact reducing estimation variability shows may dependent community.

It is difficult to understand the composition and diversity of biological communities in complex heterogeneous environments using traditional sampling methods. Recently, developments environmental DNA metabarcoding have emerged as a powerful, non-invasive method for comprehensive community characterization biodiversity monitoring different types aquatic ecosystems. In this study, water eDNA targeting fish (wf-eDNA) four methods (electrofishing, gill netting, seining, trawling) were compared evaluate reliability efficiency wf-eDNA (vertebrate mitochondrial 12S ribosomal RNA (rRNA) an alternative approach assess freshwater communities. The results showed consistency between regarding species detection. However, some detected assay not vice versa. Comparison revealed spatial homogeneity all reservoirs. Ordination analysis that covers occupies intermediate position. addition, based on Shannon index, we found one reservoir yielded similar other reservoirs, calculated index was significantly higher than general, significant positive correlations almost We conclude seems be reliable complementary biomonitoring ecosystem management ichthyofauna.

Invasive alien species cause significant loss of biodiversity. The presence invasive is often left unnoticed until they become highly abundant, and early detection by citizens can serve as an indicator invasion. Here, we aimed to investigate the probability gibel carp (Carassius gibelio) native critically endangered species, crucian carassius), using typical methods employed conservation agencies (fyke nets) (angling). Three sites with carp, nine syntopy five were investigated. proportion caught each method was compared catch per unit effort (CPUE) a measure fish density calculated number hour. Species detectability trapping angling effects waterbody type on success analysed Beta regression model. Although are closely related occupy similar positions in ecosystem, results showed high affinity for (citizen method), while higher (common professional monitoring extent that one be easily missed when sampled only methods. These bring two important findings, namely need include citizen knowledge progress potential danger underestimating invasion conservationists scientists. also suggest may overlooked citizens. This study provides example bias hinder efforts if neglected.
