Biological traits of fish sampled by electrofishing (except specific abundance indices) on the River Oir since 1988 (France).Since 1988, an annual campaign is conducted to quantify by electrofishing the abundance of fishes in the Oir basin. Originally, the main target species were salmon and trout. Beginning in 2000, eels were monitored in the same way as salmonids. The inventory of the entire fish community has been carried out on a network of seven sites. It is usually done in September and october. Two sites are also monitored in May for all species The data consist of 1738 electrofishing operations and 138765 fish caught. Biological traits measured on the fish sampled are sex, maturity status, length, weight and age. Some of the salmon, trout and eels are identified individually with a pit tag. Scale sampling is carried out on a sample to estimate the age of the fish. The survey is carried out under the Research Observatory on Diadromous Fish in Coastal Streams (ERO DiaPFC) program. The data are stored in the database of the ERO. They are used to develop predictive models and tools for providing scientific advice to improve the management of this heritage species. 2017-08-09 22:18:37.3472017-11-29 14:08:24.202857
Abundances indices and biological traits of juvenile salmon sampled in the Nivelle river (France)A survey started in 2003 is conducted every year in early autumn (late September to early October) to quantify the abundance of juvenile Atlantic salmon in the Nivelle in Pays Basque. The electric fishing protocol of Prévost and Baglinière (1995) is used. It targets Atlantic salmon young of the year (0+ parr), but older fish (juvenile salmon ≥1+) are also caught and included in this dataset. Sampling is restricted to areas with shallow running water flowing on coarse bottom substrate, i.e. the preferred habitat of young of the year salmon. The data consist of abundance indices and biological traits measured on the fish sampled: sex, maturity status, length, weight and age. The latter is ascertained from scale samples taken from the fish which size does not allow to determine their age unambiguously. The survey is carried out under the Research Observatory on Diadromes Fishes in Coastal Streamss (ERO DiaPFC) program. The data are stored in the database of the ERO. They are used to develop predictive models and tools for providing scientific advice to improve the management of this heritage species. 2016-12-20 15:29:13.9952018-01-22 16:54:18.415016
Biological traits of the smolts salmon sampled in the survey of Salmon in the Oir river (France)Since 1985, a monitoring is conducted to quantyfy the abundance of smolt Atlantic salmon on the Oir basin. In the downstream part of the Oir river, there is a trapping system which allows control the downstream migrating salmon. On this occasion, biometric characteristics are made to characterize the population to feed this data set. 2016-08-05 11:25:08.022017-11-29 14:01:42.618988
Caractéristiques des juvéniles de saumons échantillonnés lors des Indices d'abondance "Saumon" du Scorff (56) - Biological traits of the juveniles salmon sampled in the survey of Salmon abundance Indices in the Scorff riverSince 1993, an annual campaign is conducted to quantify the abundance of juvenile Atlantic salmon in the Scorff basin. It is usually done in September and according to the protocol of Prévost and Baglinière (1995). This data set consists of the biological traits measured on the fish sampled on this occasion. 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. 2016-12-20 15:53:36.0492017-11-29 14:01:42.618988
