Pathology 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 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...
متن کاملCrangon crangon (Decapoda, Natantia)
Preliminary observations indicated that the shrimp Crangon crangon (L.) appeared to be affected by the level of the ambient noise expressed as sound pressure. The significance of ~ t s metabolic response was studied by comparing its ammonia excretion rate under usual laboratory conditions E (= +25 dB pbar-l) to its rate under sound-proof conditions C (= -4 dB pbar-l). The relationship between t...
متن کاملOsmoregulation, immunolocalization of Na+/K+-ATPase, and ultrastructure of branchial epithelia in the developing brown shrimp, Crangon crangon (Decapoda, Caridea).
Aspects of osmoregulation including salinity tolerance, osmoregulatory capacity, location of transporting epithelia, and the expression of the enzyme Na+/K+-ATPase were investigated in the developing brown shrimp, Crangon crangon (L.), from the North Sea. Early developmental stages and large juveniles were exposed to a wide range of salinities for measurement of hemolymph osmolality and surviva...
متن کاملFirst Description of a Pure-search Mating System and Protandry in the Shrimp Rhynchocinetes Uritai (decapoda: Caridea)
Previous studies on two species of the genus Rhynchocinetes (‘‘hingebeak’’ shrimps) have described mating systems in which large dominant ‘‘robustus’’ males, with hypertrophied cheliped and third maxilliped weaponry, guard and defend smaller females during copulation. The sexual system of these species is gonochoric (separate sexes). In this preliminary study on the sexual biology of R. uritai,...
