Six species beneath the surface
Vive Cabeceiras · Cavez · monitorização de 2016–2017

A sampling survey offers a small portrait of the Tâmega at Cavez.

At station 22, the 2016–2017 report recorded six fish: barbo-comum, boga-do-Norte, escalo-do-Norte, bordalo, góbio and perca-sol, using their Portuguese common names. The station profile places it in Cavez. These results document that survey; they are neither a current inventory nor directions to fishing spots.

The six names open six ways of looking at the river. The barbel leads to migration within fresh water; the nase to differences between young and adult fish; the chub to scale patterns. The bordalo and gudgeon help explore diet. The pumpkinseed introduces geographical origin. Open the cards to choose a clue and reach the species explanation.

Sampling surveys and biological profiles serve different purposes. The survey documents fish recorded at that place and time. The profiles explain general species characteristics, without demonstrating that all these behaviours were observed in Cavez. Read both together while keeping that distinction.
