| A Critical Hazard Analysis Rating (CHAR) based on the Hazard Analysis Critical Control Point (HACCP) concept is used to monitor oyster purification in New South Wales (N.S.W.), Australia. Critical areas for assessment include oyster condition, separation of raw and treated oysters, water quality (turbidity, salinity, temperature, aeration, circulation), purification period, flow rate, steriliser efficiency and tank hydraulics. Batch records and product identification are included. Purification supplements a total management program for producing safe oysters. The rating can also be used to endorse oysters produced under industry self-regulatory, quality assurance programs. The four main CHAR areas are operational standards, quality assurance, public health... |

| The study reported here sought to investigate the effect that the dredging of the harbour basins and the entrance channel has had on sediment deposition rate into the Dar es Salaam harbour. Echo-sounding was carried out along berths No 2, 3, 4, 6, 7 and 8 as a means of detecting changes to their bathymetry in the four years since 1998, when the dredging commenced. Concentrations of transported sediments into and out of the harbour were determined using sediment traps. Short-term measurement of waves and currents were also carried out. Sediment traps, a wave-gauge and a current-meter were deployed in the entrance channel during the South East and North East monsoon seasons respectively. Our results reveal that the sedimentation rates after improvement of... |
