How Fishing Nets are Made: Techniques and Tools
Fishing nets have been used for centuries and their production has evolved over time. The process of making a fishing net involves several techniques and tools that are essential for its creation. In this section, we will discuss the most common techniques and tools used to make fishing nets.
The first step in making a fishing net is to determine the size and type of net required. Once this has been decided, the netting material is cut into strips or threads of the appropriate length. These strips are then knotted together to form a grid-like structure, which is the basis of the fishing net. The knots used in the netting process can vary depending on the type of net being made, but the most common knot used is the square knot.
- Knotting: As mentioned earlier, knotting is the primary technique used in making fishing nets. It involves tying the netting material together to form a grid-like structure.
- Twisting: Twisting is another technique used in making fishing nets. It involves twisting two or more strands of netting material together to form a stronger, more durable net.
- Weaving: Weaving is another technique used in making fishing nets. It involves interlacing the netting material to create a tight-knit structure that is more durable and resistant to wear and tear.
- Netting Needle: A netting needle is a long, thin needle used to thread the netting material through the knots to form the grid-like structure of the fishing net.
- Mesh Gauge: A mesh gauge is a tool used to measure the size of the mesh in the fishing net. It is essential to ensure that the net has the correct size and mesh density for the type of fish being caught.
- Shuttle: A shuttle is a tool used to weave the netting material together. It is a flat, pointed tool with a hook at one end that is used to pick up the netting material and weave it together.
Finishing the Net
Once the netting process is complete, the fishing net is finished by adding weights and floats to the bottom and top of the net, respectively. The weights keep the net upright in the water, while the floats keep the top of the net on the surface. The fishing net is now ready to be used to catch fish.
Environmental Impact of Fishing Nets
Fishing nets are an essential tool for fishermen, but they can have a significant impact on the environment. When nets are lost or discarded, they become a form of marine debris and pose a risk to marine life. Ghost fishing, where abandoned nets continue to catch fish and other marine animals, is a serious concern.
There are also environmental concerns associated with the production of fishing nets. Synthetic materials used in nets are often made from non-renewable resources, and their production can contribute to greenhouse gas emissions and pollution.
Discarded nets can entangle marine animals, causing injuries, and often leading to their death. The nets can also damage coral reefs and other fragile ecosystems. The entanglement of marine animals in fishing gear is a major threat to marine biodiversity and can have significant ecological and economic impacts.
Discarded nets and the synthetic materials used in fishing nets can remain in the ocean for years, contributing to plastic pollution. The decomposition of these materials can release toxic chemicals into the water and harm marine life. In addition, the production and transport of fishing nets can contribute to air and water pollution.
- Natural fibers: Some fishing nets are made from natural fibers such as cotton, hemp, or jute, which are renewable resources and have a lower environmental impact than synthetic materials.
- Biodegradable materials: There are biodegradable alternatives to synthetic materials, such as polylactic acid (PLA) and polyhydroxyalkanoates (PHAs), which can break down in the ocean.
- Reducing waste: Proper disposal of fishing gear and recycling of nets can help reduce marine debris and pollution.
The environmental impact of fishing nets highlights the importance of sustainable fishing practices and the need for responsible management of marine resources. It is crucial to develop and implement solutions that address the ecological and economic impacts of fishing nets while supporting the livelihoods of fishermen and ensuring the sustainability of our oceans.
