Aquaponics & Greenhouse Gas Emissions

1 collaborator

WHAT IS IT?

A model of a commercial aquaponics operation with various parameters
GENERAL MODEL NOTES

Default Fish & Plant Parameters 1. Salmon 2. Lettuce
Model Assumptions 1. Operation size: commercial 2. Assumed relative humidity: 70% 3. Timescale: 40 ticks per day, 1.667 ticks/hr 4. All fish in the operation are held in the same tank (in the real world, most fish species would be separated by age/weight, sex, and for breeding) 5. Fish and plants are harvested in the simulation based on size 6. All season temperatures are determined using the corresponding month's averages 7. Greenhouse temperature and related greenhouse gas emissions is dependent on the fish type, climate, and season 8. Lighting duration is dependent on plant type, climate, and season 9. Heating method is dependent on climate (e.g., Japan generally utilizes electricty for their heating) 10. Water in the system is cycled through the system twice an hour and is based on the total modelled volume of the fish and plant tanks 11. Heating and electricity emissions were determined using the reference location's method of heating.

HOW IT WORKS

The user selects the parameters they are interested in investigating...
HOW TO USE IT

The 'setup' button sets up the simulation, randomly placing the fish in the tank and the plants are setup in a grid. The 'go' button runs the simulation, the fish wander around the tank, eats when one comes across food patches, reproduces, and some are harvested after eight months.
THINGS TO NOTICE

(suggested things for the user to notice while running the model)
THINGS TO TRY

(suggested things for the user to try to do (move sliders, switches, etc.) with the model)
EXTENDING THE MODEL

(suggested things to add or change in the Code tab to make the model more complicated, detailed, accurate, etc.)
NETLOGO FEATURES

(interesting or unusual features of NetLogo that the model uses, particularly in the Code tab; or where workarounds were needed for missing features)
