| In the last few decades, there has been a marked decline in the number of shad (Alosa alosa and A. fallax) landed in France, which prompted the French committee of the International Union for Conservation of Nature to list shad as a ‘Vulnerable’ species in 2010. The freshwater phases of shad life cycles have been extensively studied, but the marine phases remain poorly understood. The present study aimed to provide new insights into shad ecology by describing the marine distributions of twaite and allis shad using a presence/absence model based on bycatch data from commercial fishery surveys. Depth and salinity were identified as the main factors influencing shad distribution. Both species were primarily located in shallow areas, at depths of between 0 and... |
