“…A tremendous amount of work was carried out during this period (see the papers in Walne 1974) but since the appearance of diseases due to Marteilia refringens (Comps 1970) and Bonamia ostreae (Comps, Tige & Grizel 1980) in France and the extension of the latter across Europe (e.g. Holland: van Banning 1990, Spain: Montes, Villalba, López, Carballal & Mourelle 1991, Ireland: Culloty & Mulcahy 1996), such specific hatchery knowledge has progressively declined. However, the production demand for hatchery‐produced juveniles is predicted to increase significantly for many mollusks, due either to genetic improvement through selection (Ward, English, Mcgolddrick, Maguire, Nell & Thompson 2000; King, Janke, Roberts & Kaspar 2004) or due to a decline in natural stocks (Laing, Walker & Areal 2005).…”

To select the best microalgae for Ostrea edulis conditioning, four single species diets were fed to batches of broodstock, which were then compared using physiological and biochemical approaches. Ingestion and absorption were first studied, showing that Chaetoceros gracilis and Skeletonema marinoï were efficiently ingested (4.9–5.3 mg g−1 h−1) and absorbed (1.9–2.5 mg g−1 h−1) while Tetraselmis suecica led to the lowest physiological responses (0.36 and 0.12 mg g−1 h−1 respectively). When O. edulis were fed any microalgae except T‐ISO with only 79 mg g−1, gonads accumulated carbohydrates from 116 to 141 mg g−1 and the extent of accumulation depended on the species supplied in the order T. suecica

“…In het intergetijdegebied is de droogligduur gemaximeerd in verband met de voedselbeschikbaarheid ; in dieper water kan voedsel-en zuurstoftoevoer beperkend zijn. Platte oesters komen in estuaria (inshoregebieden) voor tot in de laag-laagwaterzone (maximaal -1 m NAP) (Montes et al 1991). In de offshore-en nearshore-gebieden kunnen platte oesters voorkomen tot 80 m diep (Hayward & Ryland, 1998).…”

“…Since the initial reports of B. ostreae by Pichot, Comps, Tigé, Grizel & Rabouin (1979), and B. exitiosus (= Bonamia sp.) by Dinamani, Hine & Jones (1987), studies have concentrated on ultrastructure (Brehélin, Bonami, Cousserans & Vivarès 1982; Hine 1991a; Hine & Wesney 1994a,b; Hine, Cochennec‐Laureau & Berthe 2001), life or developmental cycles (Hine 1991a,b; Montes, Anadon & Azevedo 1994), experimental infections (Hervio, Bachère, Boulo, Cochennec, Vuillemin, Le Coguic, Cailletaux, Mazurie & Mialhe 1995), pathology (Balouet, Poder & Cahour 1983), host:parasite interactions (Chagot, Boulo, Hervio, Mialhe, Mourton & Grizel 1992; Hine & Wesney 1994b), diagnostic techniques (Carnegie, Barber, Culloty, Figueras & Distel 2000; Cochennec, Le Roux, Berthe & Gerard 2000), resistance of selected stocks to infection (Baud, Gérard & Naciri‐Graven 1997; Naciri‐Graven, Martin, Baud, Renault & Gérard 1998), and impact on wild and cultured oyster stocks (Montes, Villalba, López, Carballal & Mourelle 1991; Robert, Borel, Pichot & Trut 1991; Cáceres‐Martinez, Robledo & Figueras 1995). These primarily diagnostic and aetiological studies have provided much scientific information, but in order to manage the disease in wild and cultured stocks, other, often basic, information is required.…”

Oysters, Ostrea chilensis, infected with Bonamia exitiosus were held under stressful conditions for 14 days, and then under normal conditions for 3.5 months, to determine the affects of stress on B.exitiosus infection levels. The stressors used were (1) air exposure for 8 h daily; (2) hot water (25–26 °C), or (3) cold water (7 °C) for 1 h daily; (4) hyposaline (15‰), or (5) hypersaline (39–40‰) water; (6) starvation in filtered sea water; and (7) vigorous stirring four times a day. A control tank held oysters in static sea water, which was changed daily. Oysters were also (8) kept in a trough among heavily infected oysters (trough exposure), or (9) in a trough without other oysters (control), for 4 months. Oysters in hyposaline conditions all died within 3 weeks, but this was apparently unrelated to Bonamia infection. Otherwise, cumulative mortalities were highest in trough exposure, cold, hypersaline and hot treatments. There was a significant difference in prevalence between treatments, and the stir, hot, cold, hypersalinity and trough exposure treatments had significantly higher intensities of infection than controls. The mean intensity of Bonamia infection was significantly higher among female and spent oysters than in male and hermaphrodite oysters.
