Marine mammals living in the oceans (cetaceans), as well as various freshwater species, such as the European otter, are aquatic mammals. Their mode of operation depends on the aquatic ecosystem where they live.

Allis shad

Updated on 04/07/2018
Définition
Sens technique

Fish species belonging to the Clupeidae family (such as sardine and herring). The allis shad are among the anadromous species (i.e. which swim up rivers to spawn in the middle part of the rivers). As such, their populations have paid a heavy price to river development (dams without fish pass facilities, extraction of gravel changing the spawning, etc). Their presence is therefore a good indicator of the status of a river development. Two species of allis shad are present (and exploited) in French waters: the allis shad (Alosa Alosa) and twaite shad (Alosa fallax).
