“…2002). Signs of ‘stress’ that are often displayed by bivalve molluscs include mantle regression, regression of the digestive tubule epithelium, pale digestive gland, oedema, haemocyte infiltration of tissues, lags in gametogenesis and increases in the frequency of ceroids (brown bodies) (Sindermann 1984).…”

Pinctada fucata Gould 1850 was first commercially cultivated in Japan in the early 1920s. Japan dominated this market until the proliferation of Akoya viral disease (AVD) in 1996. Since that time the Japanese industry has struggled. In 2000, Japanese production of Akoya pearls represented only 13% of the total world market value. A number of investigations into this downturn have concluded that the proliferation of AVD was a result of stress associated with increasing urbanization and industrialization. This relationship between environmental stress and altered immunological activity is well documented in a number of oyster species. The decline in Japanese pearl production has led to interest in Akoya cultivation in Australia. Commercial Akoya pearl oyster ventures are now in operation in the Australian states of New South Wales, Queensland and Western Australia. The development of a robust and lucrative Akoya pearl industry in Australia will rely on the cultivation and maintenance of healthy oysters. Oyster health is associated with immunological status, which can be jeopardized by both stress and disease. This review details the relationship between the oyster immune system, environmental stress and disease outbreaks in the genus Pinctada, with implications for P. fucata and the fledgling Australian industry.

“…Additional dispersal mechanisms (Carlton 1987)-oil drilling platforms, the movements of other commercially important fisheries species, the release of animals used in scientific research, the building of interoceanic and interprovincial canals (whether at sea level or not) have all been critical in the movements of a vast number of species. Particularly important in the last few years has been the increased accidental movements of pathogens and disease organisms of commercial mollusks, crustaceans, and fish around the world (Sindermann 1984(Sindermann , 1986).…”

Human activities, primarily the global movement of organisms associated with ocean-going vessels and with commercial fishery products, have lead to the redish-ibution of a vast number of marine organisms over the past five centuries. Most biological surveys postdated these transport events, so the distribution of many of these now cosmopolitan species has been interpreted as the result of natural processes, leading to underestimates of the role of humans in altm'ngpattenzs of natural diversity and dish'bution of marine otganisms along the coastal margins of the world Perceptions of the natural state of some systems versus their recent ecological alteration are illustrated by the National Estuarine Reserve Research System, within which many "natural" sanctuaries have been highly altered by exotic species The modern scale and rate of new human-mediated invasions in the ocean are difficult to recognize due to the lack of communication among scientists working with diffferent groups of organisms, dayferent habitats, and different regions. Available evidence suggests that introductions continue unabated on a large scale throughout the world Despite the existence since 1973 of a number of international conventions to control the movement of exotic marine organ-adequate control still occurs largely at the regional and local levels Present Address: Bireclor, Madlime Studies Ptogram, W i l t h m Col-Cege--Myslic Seaporr; Mystic, CT 015355.Resumen: La reorganizacidn de una gran cantidad de organismos marinos en 10s ultimos 5 siglos se debe a actividades humanus, especialmente a desplazamientos globales de organismos asociados con embarcaciones marinus y con productos pesqueros comerciales La mayon'a de encuestas bioldgicas posfechan dichos eventos de transportacidq y por consecmcia se intetpreta la dishibucidn de muchas de estas especies, hqy cosmopolitas, como resultado de p c e s o s naturales, subestimndo el rol humano en la alteracidn de la diversidad natural y en la distribucidn de organisms marinos en 10s drgenes costeros del mundo.Se ilustran percepciones sobre el estado natural de algunos sisternus versus su reciente alteracidn ecol6giw en el tro del cual muchos santuarios "naturales" ban sido fuertemente alterados por especies exdticas Debido a la falta de comunicacidn en& 10s cientificos que trabajan con diferentes grupos de organismos, habitats y regiones, es drficil reconocer la escala y tasa de las invasiones recientes en 10s ocbanos, causadospor actividudes humanas.

High levels of infection have been found in crustaceans from the heavily polluted waters of the New York Bight, USA (Gopalan & Young 1975, Young & Pearce 1975, as well as in the elevated population densities of aquaculture systems (Fisher et al 1978, Sindermann 1984.…”

The prevalence and severity of shell disease in the edible crab Cancer pagurus (L.) was investigated in animals collected from Langland Bay, Gower, South Wales, UK, at monthly intervals from 1997 to 1998. Shell disease is the progressive degradation of exoskeletal chitin accompanied by melanisation of the affected region. Over 50% of the crabs sampled had 1 or more black-spot lesions. The proportion of exoskeleton affected increased with the size of the crab. Male crabs showed significantly higher levels of the disease than females, a higher prevalence of black-spot lesions (63% in males, 40% in females) and a higher mean percentage of body covered by lesions (1 % in males, 0.2% in females). This difference between the sexes corresponded to an increase in ventral surface and chela infection in males. For both sexes, the dorsal carapace was the area most affected by the disease. Dorsal carapace regional breakdown revealed the areas most commonly affected were located to the posterior of the crab. Lesion location patterns suggested that sand abrasion injuries during back-burrowing behaviour of C. pagurus lead to the formation of shell disease lesions. Seasonal trends in shell disease were seen to be dependent on the onshore migration patterns of the different size classes and sexes over the sampling period.
