Aquaculture


1. Aquaculture is the term for farmed oceanic resources ( fish, crustaceans, and plants ).




2. Pros and Cons of Aquaculture:

 Environmental Pros:
-Adds additional supply to overfished species (ex. salmon, sea bass)
-Regions involved in aquaculture will be more involved in the protection of coastal waters
 Environmental Cons:
-Spreads parasites/harmful bacteria/diseases to local wild fish species
-Can destroy local ecosystems/habitats
-Gene-pool= not diverse enough- inbreeding
Social Pros:
- The poor can obtain fish at a lower price
- Fisherman in this trade in developing countries may have greater employment opportunities
- Fish contain 35% more fat and therefore greater concentrations of omega 3 fatty acids
Social Cons:
- Fish is more susceptible to parasites and diseases- undesirable for consumption
- Fisherman are exposed to many antibiotics in the farming process
-Humans consume an accumulation of antibiotics, pestecides, and  polychlorinated biphenyls.
Economic Pros: 
-As production of fish increases, demand increases (Jevon's Paradox)
-Countries have the power to produce their own natural resources to profit off of
-Developing countries can have more employment opportunities
Economic Cons:
-Disease spread from aquaculture to natural aquatic resources diminishes the population of natural harvestable sea-life
- As the price of fish lowers due to increase in general fish industry, wild fisherman face higher demands
-Resolving environmental issues resulting from aquaculture costs a significant amount of money

3)I believe that aquaculture is a good thing when utilized for the farming of more simple organisms such as seaweed and crustaceans however when larger fish are cultivated (ex. salmon), there are greater complications to the ecosystem and overall environment. Plants and crustaceans do not carry diseases in a way as destructive as fish-farming does. In fish farming, local wild fish are killed by diseases that are spread and ruin ecosystems. The end product of farmed fish is not ideal either. The fact that it is so highly concentrated with antibiotics, pesticides, and polychlorinated biphenyls makes the act of eating fish no longer as beneficial to human health. If our ocean is overfished, why can't the world eat less of it? Considering the numerous sources of protein and omega 3s that can be consumed from other less destructive and cheaper sources (seeds, vegetables, fungus) farmed fish is not absolutely necessary. In my opinion, instead of destroying shorelines and sea life, it would be economically and environmentally beneficial to have more agriculture in developing countries instead of aquaculture.
