Turbot is a ‘flatfish’.
Like all other flatfish they rest below the surface on the floor of a body of water, where color enables them to look like the floor’s color and texture. Both of a flatfish’s eyes sit on one side of its head and always gaze straight ‘up’ to spy feeding opportunities. Flatfish, don’t run very far to chase prey, or to secure food. Therefore, successful anglers, MUST present bait where flatfish hover, on the bottom waiting patently for feeding opportunities. Which means, you MUST present your baits and hooks where flatfish dwell in wait on the bottom.
