Nursery function of Wadden Sea tidal flats for the brown shrimp Crangon crangon
The significance of the tidal zone as nursery area for the brown shrimp Crangon crangon became evident during a study on density and size-distribution of predator populations on a 50 km2 tidal flat in the western Wadden Sea (The Netherlands). A clear picture of the nursery system and its function in the annual cycle of brown shrimp is obtained when nursery population-data are combined with expe...
متن کاملPathology and ultrastructure of an intranuclear bacilliform virus (IBV) infecting brown shrimp Crangon crangon (Decapoda: Crangonidae).
The brown shrimp Crangon crangon supports an important fishery in Europe (over 25000 t, valued at 80 million euros in 2000). Through the course of histopathological screening of crustaceans from the Clyde estuary, western Scotland, for the biological effect of contaminants, we have discovered a highly prevalent (up to 100%) non-occluded intranuclear bacilliform virus (IBV) infection in the hepa...
متن کاملHydrostatic pressure affects selective tidal stream transport in the North Sea brown shrimp (Crangon crangon).
The brown shrimp (Crangon crangon) is a highly abundant invertebrate in the North Sea, with its life cycle stages ranging from deep offshore spawning to shallow onshore nursery areas. To overcome the long distances between these two habitats, brown shrimp are suspected to use selective tidal stream transport (STST), moving with the cyclic tide currents towards their preferred water depths. Howe...
متن کاملHematodinium sp. and its bacteria-like endosymbiont in European brown shrimp (Crangon crangon)
BACKGROUND Parasitic dinoflagellates of the genus Hematodinium are significant pathogens affecting the global decapod crustacean fishery. Despite this, considerable knowledge gaps exist regarding the life history of the pathogen in vivo, and the role of free living life stages in transmission to naïve hosts. RESULTS In this study, we describe a novel disease in European brown shrimp (Crangon ...
متن کاملSeasonal variation in starvation resistance of early larval North Sea shrimp Crangon crangon (Decapoda: Crangonidae)
The North Sea shrimp Crangon crangon (Linnaeus, 1758) has seasonal dimorphism in egg size, with larger winter eggs and smaller summer eggs. In the laboratory, we compared the tolerance of nutritional stress in Zoea I larvae hatching from the different types of eggs (referred to as ‘winter larvae’, WL, and ‘summer larvae’, SL, respectively). Starvation tolerance was quantified as median point-of...
