| The symptom which characterizes the brown ring disease (BRD) in Manilla clam Ruditapes philippinarum has been observed in other Bivalvia species (Veneridae and Pectinidae). Vibrio P1, responsible of the BRD in R. philippinarum , has been detected in other Veneridae which were carrying the symptom. In mussel and oysters which are cultivated in Europe, the symptom has never been reported and Vibrio P1 has not been detected. Experimental contaminations of bivalves of commercial interest with the pathogen showed a clear Vibrio P1 sensitivity of European clam R. decussatus ; this latter seems however to be less sensitive than the Manilla clam. |

| Vibrio tapetis is the marine bacterium responsible for the brown ring disease (BRD) affecting die manila clam, Ruditapes philippinarum. Identification of V tapelis has been previously performed using biochemical criteria and serological procedures. All of these methods are time consuming and ill-adapted to individual screening. This study describes an oligonucleotidic probe (Vt446) and two PCR primers, deduced from the 16S rDNA sequence, allowing a fast and specific V tapetis identification using dot blot hybridisation and species-specific primed PCR (SSP-PCR). The probe and primers have been tested on 60 strains, including referenced Vibrio sp., Gram negative and positive bacteria, marine bacteria samples and isolated clam bacteria. For all the 19 V... |

| Two populations of the Latin American shrimp Penaeus (Litopenaeus)stylirostris domesticated in Hawaii and in New Caledonia were previously shown to be genetically differentiated and proven highly inbred. In New Caledonia, where different Vibriosis affect shrimp production and antibiotic use is banned in growing ponds, the Hawaiian population was introduced to increase the allelic variability available for local shrimp farmers and start a genetic improvement program. Growth and survival rates of the two pure populations and the two-way F-1-hybrids obtained by breeding Hawaiian animals with New Caledonian animals were assessed in several simple experiments (earthen ponds, floating cages and experimental infection challenges) during two years on two... |

| El-Max fish farm is one of the most important natural fish farm in Alexandria which is suffering from die-off of large amounts of fish. Facing this problem we must deal with the estimation of the quality of the farm raring unit environment (ponds). Analysis of samples using the Bray - Curtis similarity coefficient test yielded that, the input and El-Khandac were similar at (97%), while the eight ponds were classified at different level of similarity as follows: pond1 (B1) and pond7 (B7) were similar at (86%), B2 and B3 were similar at (90%), B14, B10 and B9 were similar at (93%), where as B11 is singly separated at (83%). Moreover, results indicate that distribution of the different bacterial groups was affected with one or more chemical parameters such as... |
