About Municipal Fishers

Municipal fishers are at the heart of the simulation. Every day, simulated municipal fishers make decisions as they go about their lives: to go fishing or not, or seek an alternative type of livelihood.

Fishers have to support their families, for which fishing is the principal means of sustenance. Some of the fish is consumed as food, or traded within the village, but most of it is quickly sold to middlemen to be exported as sashimi-grade tuna.

Fishing Profits

Currently, fishers in Mindoro are at or near the subsistence line, their income sufficient to make a living but not to make great profits. Fishing income depends on the number of hours fishers spend at sea (effort), the abundance of fish in the ocean (fish stock), the efficiency of their fishing gear, and the selling price of the fish in the middlemen market.

Understanding the charts

Per Capita Surplus after Living Costs

This chart adds up all the sources of income that fishers' families receive. This includes fishing profits as well as other sources of income, including alternative livelihoods

Families’ subsistence expenses are subtracted, so that the zero line represents a subsistence income level. Higher incomes are positive, whereas under-subsistence incomes are negative.

When fishers’ incomes fall below subsistence, they will put in additional effort, by spending more hours at sea, in an attempt to compensate for the income loss. However, when stocks are fully exploited or overfished, such extra effort will make fish stocks fall even faster.

Population

The population of municipal fishers is not a constant. When profits are high, and fishing is a profitable occupation, new fishers and new boats start joining the fishery due to internal migration as well as intrinsic population growth. Conversely, when profits are below subsistence, the number of fishing households declines. However, there is a core community that is not capable of living for many reasons (cultural, age, socioeconomic level, etc.), and they remain fishers, even in bad times.

With healthy fish stocks, fishing profits per family are relatively stable.

When fishing is profitable, the population of a fishery may go up over time due to global growth in consumer demand.
