The repository constains data describing fish community monitoring across stream sections in metropolitan France over the period 1995-2018 by the French Office of Water and Aquatic Ecosystems (ONEMA) using electrofishing.

The repository contains:

 description of fishing: fishing_protocol.csv

surface: sampled surface

opcod: fishing operation code, a unique identifier for each sampling event

station: unique identifier for each site

nb_sp, nb_ind: number of species, number of individuals

geographical information: station_basin.csv

X, Y: spatial coordinates of the station, expressed in metres in Lambert93 (epsg:2154)

basin: name of the hydrographic basin

environment: environment.csv ( _mean: mean, _med: median, _cv: coefficient of variation)

alt: altitude

d_source: distance to source

strahler: strahler order

BOD: Biological Oxygen Demand

temperature: water temperature

flow: water flow

community data: community_data.csv

species: three digits code corresponding to a given species (see Table S1, Danet et al. in revision)

nind: number of individuals

biomass: biomass in gram

Length of each fish individual: fish_length.csv

length: length of the fish in millimeter

Inferred food-web: class_network.rda

data:

class_id: size class of a fish individual

network: these data.frame can be handled by igraph::graph_from_data_frame()

from, to: "to" eats "from"

composition:

sp_class: concatenation of species and class_id columns

bm_std: biomass reported to the sampled surface
