| A model simulating growth and feeding is presented for Crassostrea gigas and incorporates such physiological processes as filtration rate, pseudo-faeces production and ingestion, oxygen consumption and spawning. The only state variable is flesh weight. This model is designed to incorporate the effects of quantity and quality of food, temperature and oyster dry weight. Comparison of simulation outputs with real data showed that the model closely simulated the seasonal changes in weight over a two-year sample interval. This simulation confirms that oyster growth in Marennes-Oleron Bay is strongly regulated by the non-organic concentration in the seston. This latter factor dilutes the potential food for oyster and causes a large amount of food rejection in... |

| A comparison was made between multi-year, multi-season cruise information from the surface waters of the Scotian shelf and satellite imagery from the Coastal Zone Colour Scanner (CZCS). The colour imagery was able to identify several physical processes on the shelf (such as outflows and upwelling) to approximately the same degree as previously reported with thermal imagery. Because processing CZCS data requires the use of atmospheric and marine models defined by a range of input parameters, the various processing steps and assumptions were evaluated for potential impact on any marine interpretation of the imagery. The shelf waters were not a pure oceanic water mass throughout the year and turbidity levels were found to be the most significant interfering... |
