Development of Crassostrea belcheri (Sowerby, 1871), Crassostrea iredalei (Faustino, 1932) and inter-specific cross spats at different salinity
Hybrids between Crassostrea belcheri (CB) and C. iredalei (CI) were produce to evaluate their aquaculture potential. These inter and intra-specific crosses consisted of CB♀XCB♂, CI♀XCI♂, CB♀XCI♂ and CI♀XCB♂. To evaluate their environmental preferences, the spats of 40 day-old were cultured in 10, 20 and 30 ppt for 30 days. Hybrids showed significantly higher (p<0.05) shell increment when cultur...
متن کاملLarval settlement and spat recovery rates of the oyster Crassostrea brasiliana (Lamarck, 1819) using different systems to induce metamorphosis.
This study aimed at the assessment, in the laboratory, of the larval settlement and spat recovery rates of oysters of the species Crassostrea brasiliana using plastic collectors, epinephrine (C9H13NO3 C4H6O6) and shell powder in settlement tanks. Polypropylene was used attached to bamboo frames. The material was chosen due to its pliability--that favours the spat detachment. Two experiments wer...
متن کاملTropomyosin, the major tropical oyster Crassostrea belcheri allergen and effect of cooking on its allergenicity
BACKGROUND Many types of shellfish including oysters are sometime cooked before ingestion and it has been demonstrated that cooking may affect the allergenicity of food. Therefore, the aim of our present study is to identify major and minor allergens of tropical oyster (Crassostrea belcheri) and to investigate the effect of different cooking processing on the allergenicity of this oyster. MET...
متن کاملA Glycoprotein in Shells of Conspecifics Induces Larval Settlement of the Pacific Oyster Crassostrea gigas
Settlement of larvae of Crassostrea gigas on shell chips (SC) prepared from shells of 11 different species of mollusks was investigated. Furthermore, the settlement inducing compound in the shell of C. gigas was extracted and subjected to various treatments to characterize the chemical cue. C. gigas larvae settled on SC of all species tested except on Patinopecten yessoensis and Atrina pinnata....
متن کاملCharacterization of Antibacterial Protein from Hemolymph of Oyster Crassostrea belcheri
The hemolymph of oyster Crassostrea belcheri was found to possess significant antibacterial activity against Vibrio harveyi, V. vulnificus and V. cholerae. Hemolymph was partially purified by gel filtration chromatography on Sephacryl S-200 and fractioned into four parts: P1, P2, P3 and P4. The P3 showed the highest antibacterial activity against V. parahaemolyticus, V. cholerae, V. alginolytic...
