Abstract |
Mysids are important components of the zooplankton biomass of estuaries and coastal regions. Twelve species were identified from the Bristol Channel and Severn Estuary (British Isles). The most abundant species was S. Spiritus (Norman). The seasonal distribution and numerical abundance of this species are described. The peak of abundance of S. spiritus occurred in the Inner Channel in September. The species contributed 43% of the total integrated omnivore standing stock. This peak of biomass was the product of the development of the juveniles from the reproductive period in the spring. Correlation analyses were carried out between S. spiritus biomass and 10 physical and biotic variables. Temperature and salinity, which are simple indices of seasonal change, exhibited significant correlations with the mysid's abundance in both months. |
