Microbial communities on fish eggs from Acanthopagrus schlegelii and Halichoeres nigrescens at the XuWen coral reef in the Gulf of Tonkin [PDF]

PeerJ, 2020
Coral reefs are an important part of the ocean ecosystem and are a vital spawning ground for marine fish. Microorganisms are abundant in this environment and play a key role in the growth and development of host species.

Small-Scale Coastal Fishing Shapes the Structure of Shallow Rocky Reef Fish in the Aegean Sea

Frontiers in Marine Science, 2019
Shallow rocky reef fish assemblages were studied in sites of low versus high fishing pressure (FP) across the Aegean Sea, in order to assess community structure at a large scale and investigate spatial variability in relation to FP, depth, and geographic

Terrestrial contributions to Afrotropical aquatic food webs: The Congo River case

Ecology and Evolution, 2019
Understanding the degree to which aquatic and terrestrial primary production fuel tropical aquatic food webs remains poorly understood, and quantifying the relative contributions of autochthonous and allochthonous inputs is methodologically challenging ...

A spatial matrix factorization method to characterize ecological assemblages as a mixture of unobserved sources: An application to fish eDNA surveys

Methods in Ecology and Evolution
Understanding how ecological assemblages vary in space and time is essential for advancing our knowledge of biodiversity dynamics and ecosystem functioning.

Environmental drivers of fish community functional diversity in arid mangroves compared to a tropical estuary

Ciencias Marinas, 2021
Mangroves are important habitats for fish across latitudinal gradients, but few studies have examined fish community functional diversity in mangroves from arid environments.

Temporal and Spatial Dynamics of the Lotic Fish Communities: A Comparison of Coffee Filter‐Based Passive eDNA Collection Versus Active eDNA Filtering

Environmental DNA
Environmental DNA (eDNA) metabarcoding is a noninvasive and cost‐effective method for fish community monitoring, enabling the determination of both the presence/absence of fish species and their relative quantity in closed systems.

COMPOSITION DU PEUPLEMENT PISCICOLE D'UN PETIT ESTUAIRE ANTHROPISÉ (LE COUESNON, FRANCE).

Knowledge and Management of Aquatic Ecosystems, 2001
Dans un petit estuaire du nord de la Bretagne (France), l'ichtyofaune a été échantillonnée lors de chaque saison d'une année sur six stations selon une répartition amont-aval. 28 espèces ont ainsi été capturées à l'aide de deux engins de pêche, une senne

Factors structuring estuarine and coastal fish communities across Japan using environmental DNA metabarcoding

Ecological Indicators, 2021
Estuarine and coastal ecosystems are important habitats for many fish species. Large-scale patterns of estuarine and coastal fish communities can be affected by geographical factors, such as water temperature and latitude, that limit or allow fish ...

High Diversity of Waters, Communities and Stressors—Design of Croatian Fish Index for Rivers (CFIR)

Diversity
Determination of the ecological state of any water body is crucial for its adequate conservation and is, moreover, required by the Water Framework Directive.

Response of potential fish community indicators to fishing [PDF]

ICES Journal of Marine Science, 2005
AbstractFish community metrics and diversity indices have often been proposed as indicators to support an Ecosystem Approach to Fisheries Management. The response of eight fish community indicators to spatio-temporal changes in fishing effort was studied by comparing the rate of change in (i) areas subject to different levels (high, medium, and low) of
