“…and Pseudornonas spp., which have been commonly reported from shell disease lesions (Cook & Lofton 1973, Cipriani et al 1980). Many of these agents are also common in estuarine waters (Hood & Myers 1974) and thus do not appear to be obligate pathogens.…”

“…All the bacteria which we isolated from shells of both clinically normal blue crabs and those with shell disease had either lipase or chitinase enzymes; some had both enzymes. These biochemical markers have been traditionally associated with shell disease pathogens (Cook & Lofton 1973. Cipriani et al 1980).…”

“…Predominant colonies were picked, purified by restreaking 3 times, and identified using API identification systems (Analytab Products, Plainview, NY, USA), as well as standard tube tests for confirmation of some reactions. All isolates were also tested for chitinase and lipase activity using standard procedures (Colwell & Wiebe 1970, Cipriani et al 1980. Fig.…”

“…The proximate causes are thereby a dysbiosis of different chitinolytic and lipolytic bacteria such as Plesiomonas, Vibrio and Aquimarina (Cipriani et al, 1980;Feinmann et al, 2017;Getchell, 1989;Meres et al, 2012;Rosen, 1967). These pathogens are common in marine environments Fisher et al, 1978;Hock, 1940;Malloy, 1978;Smolowitz et al, 1992) and are also present on the cuticle of healthy crustaceans (Rosen, 1967), in this case without any impact on the host.…”

A B S T R A C TThe prevalence of black spot shell disease is increasing among marine crustaceans worldwide. Rising seawater temperatures -often stressful for ectothermic species -are assumed to enhance the occurrence of shell disease. In the North Sea > 50% of local populations of the brown shrimp (Crangon crangon) are affected by the disease. While fisheries are suffering because diseased crustaceans are barely merchantable, the impact of shell disease on life history traits of crustaceans is little understood. To determine the role of temperature on the development of black spots and its implications for survival and physiology in the brown shrimp, a prolonged (3 months) thermal stress experiment was performed. We measured the increment of shell disease and the effect of molting in shrimps kept at control (15°C = equivalent to the seafloor temperature in the North Sea during sampling) and increased temperature (20°C = according to predictions for the end of the century). The resting metabolic rate was analyzed to determine the physiological state of diseased compared to non-diseased animals. In the present study, the warmer temperature in the range of 20°C did not increase the spot size of shell disease and no differences were observed between the two temperatures. The process of molting thereby seemed to diminish and in most of the cases even completely remove the signs of shell disease. At 15°C but not at 20°C, metabolic rate was reduced in diseased in contrast to healthy individuals. This study showed that shell disease might lead to a higher mortality rate and an impairment of the physiological state in C. crangon.

“…Chitinolytic bacteria are the principal aetiological agents involved in cuticular degradation (Vogan et al 2002). Lesion initiation, however, requires the removal of the thin non-chitincontaining epicuticular layer, and this may occur by the enzymatic activities of microorganisms (Cipriani et al 1980), wounding or abrasive injuries (Dyrynda 1998, Vogan et al 1999 or chemical attack (Schlotfeldt 1972). Thus, the causes of shell disease are likely to be area-specific, varying according to the geographic location of the crustacean population.…”

Shell disease syndrome is a degradative condition of the crustacean exoskeleton which results in the formation of black-spot lesions. Field surveys on the edible crab Cancer pagurus (L.) population at 2 sites in the Gower Peninsula of South Wales, UK, namely Langland Bay and Rhossili causeway, revealed similarities in the prevalence of shell disease but differences in the severity. Male crabs from Langland Bay displayed significantly greater severities of the disease on the dorsal carapace and ventral surfaces than those in Rhossili. The greatest severities of the disease in Langland were attributable to sand abrasion injuries during back-burrowing behaviour and prolonged exposure to high numbers of chitinolytic bacteria. Lower severities of shell disease in males from Rhossili were a reflection of the inability to back-burrow due to the nature of the onshore sediment, and hence the crabs were only exposed to low levels of chitinolytic bacteria in the water column. On areas of the causeway that permitted back-burrowing, the chitinase enzyme activities in sediments were significantly lower than those in Langland Bay. It is concluded that the potential for crustacean shell degradation is higher at Langland than Rhossili, but whether the differences in chitinolytic abilities of the sediments at the 2 sites are a result of differences in pollution levels or simply of different substratum types, remains to be determined.
