The fish featured in this section are classed as rare fish from a UK perspective as they do not turn up in catches across the country on a regular or consistent basis. Many are warm water or sub-tropical species and are therefore more common in the seas around the south and west of the British Isles. Indeed, species such as sunfish and triggerfish are increasing in numbers around Britain and the last ten years or so has seen them go from rare and notable to near-common in certain areas. However, they are certainly not common when looked at on a UK-wide basis and are therefore included in this section. Not all species are more common around the south and west – cold water rare fish such as the Atlantic wolffish, greater forkbeard and tadpole fish are more likely to be caught around the north of the UK. Other species such as the shad and angel shark are included here as they were once abundant in the UK but overfishing and destruction of their natural environment means they are now classed as a rare.
