Spatial and temporal variation in fish community of the Ria de Aveiro estuarine lagoon (Portugal).
Fish assemblages of Ria de Aveiro coastal lagoon (Northwest Portugal) were studied from February 2012 and January 2013. Sampling were monthly conducted with a traditional beach-seine net (“chincha”) at 9 sites. Multivariate approach were used in order to analyse the spatial and temporal variation in...
