Abundances and biological traits of the juveniles salmon sampled in the survey of Salmon abundance Indices in the Oir river (France)
Description
Since 1993, an annual campaign is conducted to quantify the abundance of juvenile Atlantic salmon in the Oir basin. It is usually done in September and according to the protocol of Prévost and Baglinière (1995). The electric fishing protocol of Prévost and Baglinière (1995) is used, which is specific to Atlantic salmon young of the year (0+ parr) . Sampling is restrited to areas with shallow running water flowing on coarse bottom substrate i.e. the preferred habitat of young of the year salmon.This data set consists of the abundance and biological traits measured on the fish sampled on this occasion. Observations made on this occasion are descriptive data (species, sex, maturation and biometric (length, weight). In addition, scales samples are taken to determine the age of the fish.
