What Is Line-Caught Fish and Why Does It Matter?

You will see line-caught on menus, fish counter labels, and restaurant descriptions with increasing frequency, and it is worth understanding what it actually means rather than treating it as a vague quality claim. Line-caught is a specific fishing method with real environmental consequences, and understanding it makes the case for why it matters both for the fish on your plate and for the sea it came from.

What Does Line-Caught Mean?

Line-caught fish are caught using a hook and line rather than a net. The method includes handlining, where an individual fisher works a single line with a hook or lure, and longlining, where a long main line carries multiple baited hooks. The key distinction from trawling and netting is that fish are caught individually, one at a time, rather than in bulk.

Handline fishing in particular is one of the oldest and most selective methods of catching fish. A skilled handliner targeting mackerel off the Devon coast is catching exactly the species they are after, at the size they choose to keep, and returning everything else to the water without harm.

Why Does the Method Matter Environmentally?

The primary environmental advantage of line-caught fish over trawl-caught fish is selectivity. Bottom trawls capture everything in their path: target species, juvenile fish that have not yet had the chance to reproduce, seabed habitats, and non-target species including protected animals. The bycatch from bottom trawling, fish caught unintentionally and discarded dead, represents one of the most significant inefficiencies in the global food system.

Line-caught fish by contrast produces minimal bycatch. A handliner catching mackerel is not catching dolphins, juvenile cod, or rare shark species. A longliner targeting sea bass is not dragging a net across the seabed that has taken decades to develop its ecological structure. The habitat impact of hook-and-line fishing is close to zero.

Is Line-Caught Fish Better to Eat?

Often, yes. Fish caught by line are typically killed quickly at the point of capture rather than suffocating in a net over extended periods. This rapid death produces less stress in the animal, which affects flesh quality. Less lactic acid accumulates in the muscle, and the resulting flesh is firmer, cleaner-flavoured, and longer-lasting than fish that has struggled in a net.

Freshness matters enormously for fish quality, and line-caught fish from small dayboats like those that land at Brixham market is typically sold within 24 hours of being caught. This is the key advantage of buying fish near a working port.

What We Use at Fishionados

When we can source line-caught fish from Brixham dayboats, we do. The mackerel season in particular is supplied almost entirely by handline caught fish from local boats. Our commitment to the sustainable alternatives to cod, including pollock, hake, and gurnard, reflects the same logic: we choose species and fishing methods that leave the sea in better shape than we found it.
