Fish Distribution in Fauna Data in Lagoon oFish Distribution in Fauna Data in Lagoon of Aveiro (North Portugal): a Comparative Analysis between 1758 and the Present—An Interdisciplinary Case Study

摘要

The present study aims to identify fish species mentioned in the Parish Descriptions of 1758 to the lagoon of Aveiro, comparing them with those existing at present. By crossing and interpretation of the resulting data of these two analyses (1758 and timeliness), we can identify which species that remain and those who no longer have individuals in the habitats listed in historical source. Explanatory hypotheses are presented to the absence or presence of fish species. Special attention is also being paid to anadromous and catadromous fish which are extremely vulnerable to anthropic impacts meantime introduced in lagoon and river ecosystems.
