Key Concepts

Karibu! Let's Dive into the World of Fishing!

Habari mwanafunzi! Ever enjoyed a delicious plate of ugali and fried tilapia from Lake Victoria? Or maybe some tasty prawns from the coast in Mombasa? Fishing is a massive part of our Kenyan life, from the food we eat to the jobs it creates. But to truly understand it, we need to learn some key concepts. Think of these as the essential tools in your geography toolbox. Ready? Let's cast our nets and get started!

1. What Exactly is Fishing?

At its core, fishing is the activity of trying to catch fish and other aquatic organisms. These can be from freshwater sources like our lakes and rivers, or from saltwater sources like the vast Indian Ocean. It's an economic activity that falls under the primary sector, just like farming and mining, because it involves harvesting a natural resource.

2. The Two Main Scales of Fishing

Not all fishing is the same! We can classify it based on its purpose and scale. The two main types you need to know are:

• Subsistence Fishing: This is small-scale fishing, often done using simple tools like canoes (mtumbwi), hooks, and small nets. The main goal is to catch enough fish to feed the family. Any small surplus might be sold at a local market. This is common in places like the shores of Lake Turkana or along the River Tana.
• Commercial Fishing: This is large-scale fishing with the main goal of making a profit. It involves advanced technology like large, motorised boats (trawlers), echo-sounding equipment to locate fish, and huge nets. The catch is sold to processing plants, exported, or supplied to big markets across the country.

Think About It: Imagine a fisherman named Omondi who goes out on his canoe in Lake Victoria every morning to catch fish for his family's dinner. That's subsistence. Now, picture a large ship with a crew of 20 leaving the port of Mombasa for a week to catch hundreds of kilograms of tuna to be sold in Nairobi and even exported to Europe. That's commercial.

3. Where the Fish Are: Fishing Grounds

Fishing grounds are the specific areas where fishing takes place. In Kenya, we are lucky to have two main types:

• Inland Fisheries: These are our freshwater sources. They are incredibly important for providing fish to the interior parts of the country.
  • Lakes: Lake Victoria (the largest source of Nile Perch/Mbuta), Lake Turkana, Lake Naivasha (known for crayfish), and Lake Baringo.
  • Rivers: River Tana and the Athi-Galana-Sabaki river system.
  • Dams: Man-made lakes like Masinga Dam also support fishing.
• Marine Fisheries: This refers to fishing in the saltwater of the Indian Ocean along our coastline. The area is rich in species like tuna, prawns, crabs, lobsters, and snapper. Key fishing towns include Lamu, Malindi, Mombasa, and Shimoni.

4. A Modern Approach: Aquaculture (Fish Farming)

What happens when the fish in the lakes and oceans are not enough? We farm them! Aquaculture, or fish farming, is the breeding, raising, and harvesting of fish in controlled environments like ponds, tanks, or cages.

It's becoming very popular in Kenya, especially in counties like Nyeri, Kirinyaga, and Kakamega. Farmers can raise species like Tilapia and Catfish. It's a brilliant way to increase our fish supply without putting more pressure on our natural waters.

5. Crucial Terms You Must Know

To speak like a true geographer, you need to understand these critical terms.

• Overfishing: This is a major problem! It means catching fish faster than they can reproduce and replenish their population. This can lead to the collapse of a fishery.

**The Cycle of Overfishing:**

[High Demand for Fish] ---> [Fishermen use bigger nets, more boats] ---> [Too many fish are caught, including young ones]
       ^                                                                                   |
       |                                                                                   v
[Fish population cannot recover] <--- [Fewer fish available for future] <--- [Fish stocks decline sharply]

• Sustainable Fishing: This is the solution to overfishing. It means fishing in a way that meets our current needs without compromising the ability of future generations to meet their own. It involves using nets with bigger holes to let young fish escape, respecting fishing seasons, and avoiding catching endangered species.
• By-catch: These are the unwanted fish and other marine creatures caught unintentionally while trying to catch a different species. For example, a trawler trying to catch prawns might also catch sea turtles or small sharks in its nets. This is very wasteful and harmful to the ecosystem.
• Exclusive Economic Zone (EEZ): This is a very important concept in marine fishing. It's an area of the sea, extending 200 nautical miles (about 370 km) from a country's coastline, over which that country has special rights for exploration and use of marine resources, including fishing! No other country can fish commercially in Kenya's EEZ without our permission.

Let's do a quick calculation to understand the EEZ distance.

### Calculating the EEZ in Kilometres ###

# Given Information:
1 Nautical Mile ≈ 1.852 Kilometres
The EEZ extends 200 Nautical Miles from the coast.

# Formula:
Distance in km = Distance in Nautical Miles * Conversion Factor

# Calculation:
Distance in km = 200 * 1.852
Distance in km = 370.4 km

# Conclusion:
Kenya has exclusive rights to the marine resources up to approximately 370.4 kilometres out into the Indian Ocean!

Here is a simple diagram to help you visualise it:

      KENYA (Land)

                     ||    Territorial    #      Exclusive Economic Zone (EEZ)

                     ||    (12 NM)        #          (200 NM from coastline)

Well done for making it through these key concepts! Understanding these ideas is the first step to becoming an expert on fishing in Kenya. Keep revising them, and you'll be ready to tackle any question that comes your way. Kazi nzuri!
