Title: Systems- Balancing Feedback Loop

ThesisStatement:The fishing business depends upon a balancing feedback loop ofrenewed fish population.


  1. Professor Meadow’s explanation of the fishing business depending on a reinforcing feedback loop in a system.

Stockchanges determine the rate and dynamics within which systems operate.As an example, industrialization cannot move at a faster rate thanthe rate of which industries are erected and the speed at whichpeople study to operate these industrial machines. Stocks, includingfish stocks, allow for outflows and inflows to remain independent andsometimes imbalanced. However, according to Professor Meadow, asystem aimed at stabilization, goal seeking and regulating, defines abalancing feedback loop. This type of feedback loop opposes anydirectional change the system is imposed. If a fishing stock ispushed too far up, the balancing feedback loop will try to bring itto equilibrium. Likewise, if the system is shoved too low, thebalancing loop will work against it to bring it up. This feedback isdirectly significant in the fishing business as professor Meadow putsit across. Losing a lot of fish at once will take a considerableamount of time to recover the loss. Hence, a balancing feedback loopthat is aimed at stock maintenance possesses adequate goals which aimat compensating for any inflows or drains from the system. Otherwise,the initiated process will fail if the stock population surpasses thetarget.

  1. An example of overfishing and Meadow’s implication that balancing feedback loop should be respected.

Fishregeneration is not a constant value but varies according to thedensity of fish in a particular area. If the population of fish istoo high, then the reproduction rates among the fish are almost zero.This aspect is attributed to heightened competition for food andspace. If the fish population declines at a smaller margin, the fishcan regenerate much faster because of usable resources within theshared habitat. However, if the fish population declines by a largermargin, the numbers do not improve but declines even further becausethey cannot find partners to breed with or a different species havedominated their niche. These are the implications of overfishing. Thetragedy of the commons exhausts the fish population in most globalfisheries because no feedback exists between the fishing populationand the verdict to capitalize on fishing equipment and vessels suchas boats.

Itis important to note that the common fallacy that fish price is apositive feedback is wrong. This opinion states that as fish becomescarce, the prices in the market shoot and fishing becomes a moreprofitable business. However, this is a tenacious feedback that willonly lead to the collapse of the system. Professor Meadow advocatesfor the respect of balancing feedback loops. This is because theworld’s renewable resources are flow limited. These resources canonly support extraction at a restricted rate that is equal to theregeneration frequency. If the fish are extracted at a faster ratethan the speed at which they regenerate, the populations may finallyfall below the critical edge hence, becoming both a non-renewablebusiness activity and non-renewable resource.


Withthe ever increasing human population, there is a self-centeredconcept of wanting to exploit everything. Although there is a subtleidea that these resources will eventually be depleted and cause thecollapse of systems, many people continue to disregard the idea.Therefore, being conscious about the systems around is being mindfulof the future generations.
