System Zoo Z409 Fishery dynamics from Hartmut Bossel (2007) System Zoo 2 Simulation Models. Climate, Ecosystems, Resources
Fishing is a classic example for use of a renewable resource. Unless overfished, fish populations If is hardly by fishing, then the fish population will persist at a constant size corresponding to its specific ecological envi ronment If the stock is overfished, the juvenile generation becomes too small to fully replace the adult generation. If overfishing continues. the population cannot recover and will collapse in short time. Even if fish catch stops now/, it could take decades until the fish population recovers to its original size if it hasn't become extinct meanwhile. In many of the world overtlshing has led, and still leads, to the complete collapse of formerly huge tlsh populations: herring in the North Sea, codtlsh in the Northern Atlantic. tuna, whales to name only a few. With the collapse of fish stocks came the collapse of the t1shing industry in many regions. Employment and
incomes disappeared: whole regions (like Newfoundland) lost their economic base.

Acest model este adaptat după reprezentarea lui Harmut Bossel, în lucrarea "System Zoo 3 Simulation Models, Economy, Society, Development."
Utilizarea modelului ne poate ajuta pentru a vizualiza evolutia populatiei pe grupe de varsta sau pentru a gestiona probleme cum ar fi ocuparea forței de muncă.

System Zoo Z302 - Global carbon circulation from Hartmut Bossel (2007) System Zoo 2 Simulation Models. Climate, Ecosystems, Resources
By photosynthesis and decomposition of organic matter (stand litter and humus) and by respiration of plants and animals large amounts of carbon dioxide are constantly being removed from and returned to the atmosphere. These gigantic C02 flowswere in equilibrium over millions of years. Annual C02 gains and losses of the atmosphere balanced rather exactly, so that the atmospheric C02 level hardly changed. Since the beginning of industrialization this dynamic equilibrium between the reservoirs of atmosphere and (living and dead) biomass has been disturbed by the burningof fossil fuels and the deforestation of large areas. Every year more C02 now reaches the atmosphere than is taken out by photosynthesis. This leads to an increasing fraction of the greenhouse gas C02 in the atmosphere a major cause of gradual temperature increase and of climate change.

Based on the Market and Price simulation model in System Zoo 3, Z504. In this model the profit calculations were not realistic. They were based on the per unit profit, which does not take items not sold into account. Also the model was not very clear on profit since it was included in the total production costs and consequently in the unit costs and subsequently profit was calculated by subtracting unit costs of the market price. Thus profit had a double layer which does not make the model better accessible. I have tried to remedy both in this simplified version.
