“…When Crangon crangon was exposed to salinity variations over 6 h according to the present estuarine conditions a similar response was observed; its ammonia excretion rate increased crangon responded rather less to decrease than to increase in salinity. This was consistent with the findings for the summer cycle (Regnault, 1983a) and Needham's (1957) and Hagerman's (1971) remarks already discussed by Regnault (1983a). Furthermore, consistent responses to salinity changes of similar amplitude and direction were rarely observed and, in some ranges of values, the salinity change had no effect on ammonia excretion (Fig.…”

Salinity-induced changes in ammonia excretionas salinity drops from 34 %O to 14 %o, and is reduced to '1% during flood tide as the salinity returns to 34 %. The excretory response of C. crangon is influenced by at least 3 factors: direction of salinity change, salinity range over which the change occurred, and the velocity of this change. The effects of salinity fluctuations on the ammonia excretion rate of C. crangon are discussed in relation to the osmoregulatory mechanisms involved in the shrimp's adaptation to changing salinity. The excretory response of C. crangon to a winter tidal cycle is compared to that previously observed under summer conditions. The winter response is characterized by a much larger amplitude and a delay in adaptation. This last point is discussed in relation to the size of shrimp and the experimental temperature, both fitted to winter conditions. Total ammonia production over a 12 h tidal cycle was 167.53 k 3.47 pg N g 1 wet wt in shrimp undergoing tidal cycles, and 95.40 Â 9.83 pg N in shrimp maintained at a constant salinity (34 %o). Consequently, shrimp in estuarine conditions face a noticeable nitrogen loss compared to shrimp staying offshore. As opposed to summer conditions where the loss was negligible, some behavioural changes (migration, burrowing) are necessary for shrimp in order to survive winter estuarine conditions without damage.

“…The brown shrimp, Crangon crangon, is a hyper-/hyporegulator common in marine and estuarine areas, particularly in the North Sea and the Baltic Sea (Hagerman 1971;McLusky et al 1982). Generally considered as a very euryhaline species (Dornheim 1969;Heerebout 1974), its broad salinity tolerance allows for a distribution in areas with fluctuating and/or constantly low salinities.…”

“…Low salinity was compensated by hyperosmoregulation and higher salinities by effective hypoosmoregulation, and the isoosmotic point (isoosmoticity between hemolymph and medium) was found at ≈25‰. After appropriate acclimation time, this pattern occurs in animals originating from marine (North Sea) or from brackish populations (Baltic Sea;Broekema 1942;Flügel 1960;Weber and Spaargaren 1970;Hagerman 1971;McLusky et al 1982).…”

“…Hence, its ecology and physiology have been the subject of numerous investigations, and a fair amount of information is available on, for instance, the effects of heavy metal contamination (Papathanassiou 1985), population dynamics (Temming and Damm 2002), and ionic regulation in adults (Hagerman 1971;McLusky et al 1982). Hagerman (1971) provided a detailed description of the osmoregulatory capabilities of adult Crangon vulgaris Fabr. (pC.…”

Aspects of osmoregulation including salinity tolerance, osmoregulatory capacity, location of transporting epithelia, and the expression of the enzyme Na ϩ /K ϩ -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 survival rates. In media ranging from 17.0‰ to 32.2‰, salinity tolerance was generally high (survival rates: 70%-100%) in all developmental stages, but it decreased in media !10.2‰. Zoeal stages and decapodids slightly hyperregulated at 17.0‰ and osmoconformed in media ≥25.5‰. At 10.2‰, these stages showed high mortality, and only juveniles survived at 5.3‰. Juveniles hyperregulated at 10.2‰ and 17.0‰, osmoconformed at 25.5‰, and hyporegulated in media ≥32.2‰. Large juveniles hyperregulated also at 5.3‰. Expression of the Na ϩ /K ϩ -ATPase and ion-transporting cells was located through immunofluorescence microscopy and transmission electron microscopy. In zoeae I and VI, a strong immunoreactivity was observed in cells of the inner epithelia of the branchiostegites and in epithelial cells lining

Long‐term adaptation to low salinities in the euryhaline shrimp Crangon franciscorum (Stimpson)

The euryhaline shrimp Crangon fi.anciscorum is a hyper-hypoosmotic regulator, its hemolymph being iso-osmotic with the medium near 27 0100 salinity. Shrimp collected from low salinity environments are physiologically very distinct from those collected from high salinity environments. Individuals from low salinity habitats exhibit better survival, a lower water content and apparent permeability to water, and a decreased rate of sodium loss in low salinities when compared to shrimp from high salinity habitats. These differences persist after several days of adaptation to low salinity, however after acclimation to a low salinity for a longer time (5-6 weeks in this study), these differences disappear.Some studies concerning the acclimation of crustacea to a salinity change show that, after transfer to a new salinity, the osmotic concentration of the hemolymph (or concentrations of ions) reaches a new level within a relatively short time, usually between a few hours to a week (Flugel, '60; Grimm, '68; Haefner, '69; Hagerman, '71; Horlyck, '73; Thompson and Pritchard, '69; Williams, '60). After transfer to a lower salinity, the osmotic concentration of the hemolymph often stabilizes at a new level, and remains unchanged for several days. However, there is also evidence of a long term component of acclimation, one that requires considerably more time to complete. For example, several investigators have observed that animals collected from high salinities differ in osmoregulatory abilities from animals collected from low salinities (Anderson and Prosser '53; McLusky, '79; McLusky et al., '82; Segal and Burbanck, '63: Tagatz, '71; Theede, '69; Weber and Spaargaren, '70). This effect could be due to 1) genotypic differences between animals inhabiting high and low salinity habitats or, alternatively 2) incomplete acclimation in the lab of the high salinity animals to low salinity. McLusky et al. ('82) have shown that in the European shrimp Crangon crangon this effect is phenotypic, and not a result of genetic differences between populations. We have attempted to distinguish between these two possibilities in the study described in this report, and we will show that, at least for Crangon fi-anciscorm, a euryhaline shrimp and the subject of the present studies, shrimp transferred from high to low salinity rapidly lower the osmotic concentration of their hemolymph. This concentration then remains unchanged for several days and is very different from that of shrimp from low salinity habitats. This difference is in part due to differences in water content, apparent permeability to water, and rate of sodium loss between shrimp acclimated short term to high and low salinities. However, after a longer period of acclimation in the low salinity, the former high salinity animals become physiologically more similar to those collected from low salinity. MATERIALS AND METHODS Sources of shrimpShrimp were collected by trawl from two localities: 1) a system of sloughs north of Suisun Bay in the Sacramento -San Joaquin Delta,...
