Here are the Differences Between the Longline and Handline Fishing Methods

Kelolalaut.com Fishing has been a cornerstone of human sustenance and industry for centuries, evolving into a variety of specialized methods suited to different needs and environments. Two prominent fishing techniques, longline and handline fishing, are widely used across the globe. Despite both being hook-and-line methods, they differ significantly in scale, setup, environmental impact, and economic viability.

Longline Fishing

Longline fishing is a large-scale commercial fishing technique designed to catch a high volume of fish. It involves deploying a mainline that can stretch for miles, with thousands of baited hooks attached to branch lines, or "snoods," spaced at regular intervals. The line is typically set in open water and can be placed at various depths to target specific species, such as tuna, swordfish, or halibut.

This method is highly efficient for capturing large quantities of fish in a single operation. However, it has raised environmental concerns due to bycatch, the unintentional capture of non-target species like sharks, seabirds, and sea turtles. Efforts to mitigate this include using circle hooks, weighted lines, and bird-scaring devices.

Longline fishing requires significant investment in equipment, vessels, and crew. It is predominantly used by commercial fishing fleets, with operations spanning days or even weeks at sea. While highly productive, its large-scale nature and environmental impact make it a controversial method in sustainable fishing discussions.

Handline Fishing

In contrast, handline fishing is a simple, small-scale method that involves using a single fishing line, hook, and bait. The line is held and operated manually, making it one of the most traditional and sustainable fishing techniques. Handline fishing is commonly used in artisanal and recreational fisheries to catch species like cod, snapper, and mackerel.

This method is highly selective, minimizing bycatch and reducing harm to marine ecosystems. Fishers can quickly release non-target species or undersized fish, ensuring compliance with regulations and promoting conservation. The simplicity of the equipment also makes handline fishing an economically accessible option for small-scale fishers.

However, handline fishing is labour-intensive and yields smaller catches compared to longline fishing. It is best suited for nearshore or coastal fishing, as it is not practical for deep-sea or large-scale commercial operations. Despite its limitations, handline fishing remains a valuable method for sustainable and community-based fisheries.

Key Differences

The primary distinction between longline and handline fishing lies in their scale and purpose. Longline fishing is designed for mass harvesting, targeting commercial markets and large-scale operations. It demands significant resources but poses risks to marine biodiversity. Handline fishing, on the other hand, is small-scale, selective, and environmentally friendly, catering to local markets and personal consumption.

In terms of environmental impact, longline fishing's bycatch rates and habitat disruption contrast sharply with handline fishing's minimal ecological footprint. While longline fishing drives global seafood supply, handline fishing supports livelihoods in coastal communities and promotes sustainability.

Both longline and handline fishing play vital roles in the fishing industry, catering to different scales and objectives. As global demand for seafood continues to grow, balancing efficiency with sustainability remains crucial. While longline fishing meets commercial needs, handline fishing exemplifies the principles of responsible and eco-friendly fishing, ensuring the health of marine ecosystems for future generations.
