Methods of Fishing

Back to: Pre Vocational Studies JSS 2

 

Welcome to class

In our previous lesson, we learned about  the various uses of fish and fish products. Today, we’re going to go deeper into the different methods that people use to catch fish, from traditional techniques to modern technologies.

Traditional Fishing Methods

• Handline Fishing: Using a simple line with a hook and bait to catch fish. This method is often used for recreational fishing and can be done from the shore or a boat. It’s a classic technique that requires patience and skill.
• Net Fishing: Using nets to capture fish in large quantities. There are various types of nets, including:
  • Gillnets: Nets that catch fish by their gills. Gillnets are often used in commercial fishing, but they can also have a significant impact on marine ecosystems, as they can capture non-target species.
  • Seine nets: Nets that are pulled through the water to enclose fish. Seine nets are often used in coastal areas and can be used to capture a wide variety of fish species.
  • Trammel nets: Nets that have two layers, with the fish becoming entangled in the inner layer. Trammel nets are often used in deep-sea fishing and can capture large quantities of fish.
• Hook and Line: Using a line with a hook and bait to catch fish. This method is often used for recreational fishing and can be done from the shore or a boat. It’s a popular method for catching a variety of fish species, from small panfish to large game fish.
• Harpoon Fishing: Using a long, barbed spear to pierce and capture fish. This method is often used for large fish, such as tuna and marlin, and requires a high degree of skill and accuracy.
• Trapping: Using traps or cages to capture fish. This method is often used for shellfish, such as crabs and lobsters, and can be a sustainable way to harvest these resources.

Modern Fishing Methods

• Longline Fishing: Using a long line with thousands of hooks attached to catch fish. This method is often used for deep-sea fishing, targeting species like tuna and cod. Longline fishing can have a significant impact on marine ecosystems, as it can lead to bycatch of non-target species, such as seabirds and turtles.
• Purse Seining: Using a large net that is encircled around a school of fish and then pulled closed to capture them. This method is often used for small fish, such as anchovies and sardines, and can be a highly efficient way to catch large quantities of fish.
• Trawling: Using a large net that is dragged along the bottom of the ocean to catch fish. This method can have a devastating impact on marine ecosystems, as it can destroy habitats and capture non-target species. Trawling is often banned or restricted in certain areas to protect sensitive ecosystems.
• Aquaculture: Farming fish in controlled environments, such as ponds, tanks, or cages. Aquaculture can help reduce pressure on wild fish populations and provide a sustainable source of seafood. However, it’s important to ensure that aquaculture practices are sustainable and do not have negative impacts on the environment or local communities.

Summary 

Fishing has been a human activity for thousands of years, and it continues to play a vital role in our lives. By understanding the different methods of fishing and the importance of sustainable practices, we can ensure the long-term health of our oceans and the continued enjoyment of this ancient pastime. It’s important to choose sustainable seafood options and support efforts to protect marine ecosystems.
