| 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... |
