Simple phytoplankton and oyster model

Joao G. Ferreira
Very simple model demonstrating growth of phytoplankton using Steele's equation for potential production and Michaelis-Menten equation for nutrient limitation.

Both light and nutrients (e.g. nitrogen) are modelled as forcing functions, and the model is "over-calibrated" for stability.

The phytoplankton model approximately reproduces the spring-summer diatom bloom and the (smaller) late summer dinoflagellate bloom.
 
Oyster growth is modelled only as a throughput from algae. Further developments would include filtration as a function of oyster biomass, oyster mortality, and other adjustments.

Pacific oyster, Crassostrea gigas, growth model

Pacific oyster, Crassostrea gigas, growth model 
Implementation of the model developed by Kobayashi et al., (1997). The model was setted to individual growth. 
Reproduction and effects of TPM on filtration rate (FR) were not included. [yellow variables]
The values of Chlorophyll, Salinity and Water Temperature are from Mondol et al., (2016). 
The growth follows a similar trend of that reported by Modol et al., (2016) but the wet weight tissue values are 3 times higher that the expected.

Eastern oyster, Crassostrea virginica, growth model

Eastern oyster, Crassostrea virginica, growth model
Implementation of the model presented by Cerco (2014), with a lot of adaptations. Model translates the individual growth. 

The food source was only considered as phytoplankton, and the forcing variables temperature, DO and salinity were not considered.
