Living in the Agricultural World #9

Source

Fish farming is widely practiced in many countries around the world. Fish are one of the most highly demanded sources of meals all over the world. This is due to both their nutritional and health benefits, such as high-quality protein, a good source of minerals and vitamins, and fatty acids. Other health benefits include cancer prevention, heart health, and improved eye health, brain function, and development. They also serve as a source of food and a means of income.

What are the most commonly cultured fish species (e.g., salmon, tilapia, shrimp)? Write in your own words.

Let me briefly list the few most commonly cultured fish species, on which I will also place emphasis.

Tilapia

Source

This is one of the most commonly cultured fish species around the world. It is best known for its high growth rate, which enhances economic activities. It has the ability to adapt to any environment and also has high disease resistance.

Shrimp

This is a member of the crustaceans family and is one of the most common cultured fish species in many countries. It is also rich in protein and is a source of economic development.

Catfish

Source

This is another common species cultured in many countries around the world, and it is also very rich in protein. In my locality, it is one of the most consumed fish species.

Salmon

This is another species mostly cultured for food and economic purposes; it is also rich in protein and includes other nutritional values.

How do different species requirements impact aquaculture operations (e.g., water temperature, feed)? Explain with examples.

Regarding this aspect, I have been fortunate to visit a fish farm in my locality. I learned about the temperature and feed supplements on which most of these species rely for proper development.
Species such as:

• Tilapia inhabit warm water with low salinity levels.
• Salmon requires cold water, which enhances their growth.
• Shrimp requires warm water with a specific salt level.

What are the challenges and opportunities in culturing non-traditional species (e.g., seaweed, shellfish)?.

CHALLENGES

The establishment of non-traditional species like seaweed and shellfish may be costly and time-consuming since it will require new cultural methods for maintenance.
Means to tackle diseases and pests that may affect the species must be established, which may also be costly to develop.
Additionally, people may not be familiar with these species, which may affect economic development.

OPPORTUNITIES

Culturing non-traditional species may bring about job opportunities, as people will be eager to try new things. It will also serve as a source of food and other nutritional benefits.
In terms of technology, researchers may be keen to develop new technologies that will help aquacultural operations, also leading to job creation.
