The Longline; A Look At The Hook

In this episode, we examine longlining in the Northeast Atlantic, focusing on fishing activity off the coasts of Portugal and Spain. Longlining is a widely used commercial fishing method involving baited hooks deployed across long distances in open wate

We explore how the practice developed into a major industrial fishery in the region, the species it primarily targets, and how catch composition has shifted over time, including increasing interactions with shark populations. The episode also looks at how longline gear operates in practice, where the catch enters global supply chains, and how different markets make use of both target and non-target species.

Finally, we consider alternative fishing methods with lower bycatch rates, alongside ongoing debates around sustainability, transparency, and fisheries management.

Description

Sharklines: The Beat is an investigative report on fishing, the fish we eat and the hidden economics of the ocean. I’m Rory Forsyth, and together we’re diving into the hidden world behind the fish on your plate. From sharks and tuna to fishing fleets, bycatch and billion-pound industries, we’ll follow the journey from ocean to supermarket shelf to uncover what really happens in the supply chain. How does a fish caught in deep water end up fresh in your fridge days later? Who decides what lives, what dies, and what gets sold? Through science, experts and firsthand voices, we will find out.
