A preliminary characterisation of the habitat use and feeding of Allis shad (Alosa alosa) juveniles in the Minho River tidal freshwater wetlands
The availability of high-quality rearing areas and survival during the early life-history stages are considered key factors determining the number of recruits produced and are prerequisites for the successful recruitment of several fish species. To identify the freshwater habitat use of Allis shad,...

| Sumario: | The availability of high-quality rearing areas and survival during the early life-history stages are considered key factors determining the number of recruits produced and are prerequisites for the successful recruitment of several fish species. To identify the freshwater habitat use of Allis shad, several samples were collected in the tidal and non-tidal freshwater areas of the Minho River during the autumn of 2009. The two places where juveniles were found are substantially different in terms of sediment texture and organic matter but similar in depth and water current velocities. The food items found in the stomach contents may indicate that movements of juveniles occur in the estuary. |
