This model simulates the growth of carp in an aquaculture pond, both with respect to production and environmental effects.  Both the anabolism and fasting catabolism functions contain elements of allometry, through the m and n exponents that reduce the ration per unit body weight as the animal grows
This model simulates the growth of carp in an aquaculture pond, both with respect to production and environmental effects.

Both the anabolism and fasting catabolism functions contain elements of allometry, through the m and n exponents that reduce the ration per unit body weight as the animal grows bigger.

The 'S' term provides a growth adjustment with respect to the number of fish, so implicitly adds competition (for food, oxygen, space, etc).

 Carp are mainly cultivated in Asia and Europe, and contribute to the world food supply.

Aquaculture currently produces sixty million tonnes of fish and shellfish every year. In May 2013, aquaculture production overtook wild fisheries for human consumption.

This paradigm shift last occurred in the Neolithic period, ten thousand years ago, when agriculture displaced hunter-gatherers as a source of human food.

Aquaculture is here to stay, and wild fish capture (fishing) will never again exceed cultivation.

Recreational fishing will remain a human activity, just as hunting still is, after ten thousand years - but it won't be a major source of food from the seas.

The best way to preserve wild fish is not to fish them.

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.

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.

Simple mass balance model for aquaculture area, based on the Vollenweider equation:

dMw/dt = Min - sMw - Mout

The model was first used in the 1960s to determine the phosphorus concentration in lakes and reservoirs for eutrophication assessment.

Direct loading replaces input concentration

The key uncertainty in these models is s, the loss of phosphorus to the sediment. Calculation of s, and the retention coefficient R used in the Dillon & Rigler model, was extensively analysed on the basis of existing literature, and the final equation used was from Canfield & Bachmann, 1981, for natural lakes.
