The concentrations of nine elements (Ag, As, Cd, Co, Cr, Cu, Mn, Ni and Zn) were measured in the oyster Isognomon isognomon and the edible clam Gafrarium tumidum from different sites along the SW New Caledonian coast which is subjected to important chemical inputs due to intense land-based mining activities (New Caledonia is the third world producer of nickel). Results indicate that concentrati...

23 The concentrations of 9 elements (Ag, As, Cd, Co, Cr, Cu, Mn, Ni and Zn) were measured 24 in the oyster Isognomon isognomon and the edible clam Gafrarium tumidum from different 25 sites along the SW New Caledonian coast which is subjected to important chemical inputs due 26 to intense land-based mining activities (New Caledonia is the third world producer of nickel). 27 Results indicate that...

In April, 1992, paralytic toxicity substantially exceeding the quarantine limit of 4MU/g edible part as paralytic shellfish poison (PSP) was detected in cultured oyster Crassostrea gigas, mussel Mytilus edulis and short-necked clam Tapes (Amygdala) japonica from Hiroshima Bay, Hiroshima Prefecture concomitantly with the appearance of the toxic dinoflagellate Alexandrium tamarense. The toxicitie...

Ostreolysin (Oly), an acidic, 15 kDa protein from the edible oyster mushroom (Pleurotus ostreatus), is a toxic, pore-forming cytolysin. In this paper, its toxic properties have been studied in rodents and the LD(50) in mice shown to be 1170 microg/kg. Electrocardiogram, arterial blood pressure and respiratory activity were recorded under general anaesthesia, in intact, pharmacologically vagotom...

The impact of coastal pollution was studied using edible oysters, Crassostrea rivularis as an indicator at two sites viz., North Wandoor (NW) and Phoenix Jetty (PJ) in Port Blair, Andaman. The hydrographic parameters showed that nitrite, nitrate and phosphate concentration were less and dissolved oxygen were more at NW compared to PJ. The oysters were collected from the study sites and biochemi...

Pleurotus eous is an edible oyster mushroom currently available in Southern part of India. There is no information about the antioxidant and therapeutic properties of this mushroom. Pleurotus eous aqueous extract (PEAE) were prepared and analysed for their antioxidant activity by in vitro assays such as DPPH, hydroxyl radicals, Ferric Thiocyanate (FTC) and Thiobarbituric acid (TBA) test. The ne...

The present study forms the first report of Nematopsis sp. infection in the edible oyster, Crassostrea madrasensis from India. The study was carried out as part of a detailed pathological investigation of C. madrasensis along the southwest coast of India. Sporozoites of Nematopsis sp. were found in samples collected from two locations. Light microscopic observation revealed ellipsoidal oocysts ...

1 Hasija Hasanspahić, DVM, MSc, Veterinary Inspectorate, Federal Administration for Inspection Issues, Sarajevo Canton, Bosnia and Herzegovina Summary This study evaluated the sensory characteristics of oyster (Ostrea edulis) samples during refrigeration at the temperatures of 4°C, 7°C and 15°C at several time points (one, three, five, seven, nine and eleven days). The indicators of shellfish q...
