- Size: Up to 6ft and 100lbs, although in some locations the maximum size can be 20-30lbs.
- UK minimum size: 9kgs/20lbs (as a shark species tope has a minimum weight rather than length)

- Distribution: Wide distribution around the UK, but more common around the south east, southern and western coasts of the British Isles.
- Feeds on: Tope feed on a variety of different fish such as dab, flounder and pouting, as well as mackerel and herring. They will also take squid and on occasion crustaceans.
- Description: Slim, streamlined body and long pointed snout. Greyish upper body, sometimes with a brownish tinge and white belly with distinctive, notched tail. Two dorsal fins and large, powerful pectoral fins. Mouth full of small but extremely sharp teeth. Males identified by the presence of the clasper near to the anal fin.
Tope is a species of shark from the Triakidae family. It is a slim and yet powerful fish which is highly prized by anglers for its fighting power and the prestige of catching a shark species. While it is a species primarily associated with boat fishing it is possible to catch smaller tope from the shore, with a number of much larger fish caught by shore anglers every year.
Distribution and Habitat
Tope are found in sub-tropical and temperate waters around the world. They are found around North and off the Argentinian and Brazilian coasts of South America, off the coast of South Africa and throughout Australian and New Zealand waters. In Europe the are found throughout the Mediterranean, Atlantic and parts of the North Sea. In terms of UK distribution they are more common in the southern North Sea, south coast, south west, Wales and along the west coast of Scotland. It is rare to find tope outside of these areas, although they have been reported on rare occasions. Tope do not favour very rough ground but will be found over light mixed ground and sandy and shingle areas, usually with a decent tidal flow. Tope will come into large inshore estuaries and bays, but some depth of water is still required as they will not come into very shallow water. In south east England the Thames Estuary holds tope, as does Morecambe Bay in north west England and Luce Bay in south west Scotland. There are also tope in the fast running Bristol channel, off the coast of Cornwall and all around the coast of the Republic of Ireland. Tope are not a deep-sea fish and are found in a maximum depth of two or three hundred metres deep. Smaller tope, up to 20-30lbs may stay in small packs and hunt together with larger fish tending to be solitary. Tope are nomadic and can travel huge distances in their lifetime. It is not unusual for tope tagged in Europe to be found again in South American or southern African waters.
Spawning and Reproduction
Breeding takes place in late winter and spring. Tope are ovoviviparous, which means fertilised eggs hatch in the bodies of females making it look as if they give birth to live young. Eggs take around a year to develop inside of the females and are released into fairly shallow bays and estuaries. Usually six or seven pups are released but it can be many more than this in some cases. Pups are around one foot long at birth.
Commercial Value of Tope
There is little demand for tope from UK consumers and commercial vessels from Britain do not target this species, although it is caught as bycatch and discarded at sea. In warmer waters tope can also be caught on commercial long-lines meant for tuna. While tope is not eaten in the UK, it is popular in other European countries such as Spain, where it is marinated and then deep fried to create the dish of cazón. Tope are also exported to Asia where they are utilised for shark fin soup – hence the alternative nickname of the soupfin shark. The liver is also used for oil and the skin made into leather. The IUCN (International Union for the Conservation of Nature) classes the tope as Vulnerable meaning that it is at risk of becoming an endangered species. Greenpeace have also added tope to their redlist of fish species which are have a very high risk of being sourced from unsustainable fisheries.
Tope adapt well to being kept in captivity and can be seen in many large-scale aquariums and sea life centres across the world. Tope have never been recorded carrying out an unprovoked on humans.
Methods and Techniques to Catch Tope
Tope are very much seen as a boat fishing species and it is not common to catch a tope from the shore. Boat anglers fish for tope using heavy 50lb-class gear, as tope is a powerful fish which can run in the tide making it even more difficult to reel in. Rigs consist of a wire hooklength to protect against the tope’s sharp teeth and a heavy monofilament rubbing leader as the rough skin of the tope can tear through weaker line. Hook size is not generally too large, as this will make smaller sub-20lbs tope difficult to hook. Strong patterns in size 5/0 or 6/0 are the best choice as they can hook smaller fish and handle anything larger that comes along.
Small boat anglers catch tope just a few hundred metres out to sea, and in places such as this it will be perfectly possible to catch this species from the shore. Placing a bait into a deep fast-running gully where small fish are likely to congregate offer the best chance of shore-based anglers catching a tope. Tackle needs to be strong, as even a smallish tope will put up a great fight, especially if it can use the strength of the tide to its advantage. Large multipliers and stiff, sturdy beachasters are the only choice. Remember a tope will run and need to be given line so ensure that clutches and drags are set correctly prior to beginning to fish for this species, or the ratchet (line out alarm) is used. In terms of rigs a single hook clipped down behind an impact shield will be needed, as large baits will need to be cast a decent distance. Hook size should be 4/0 in a strong, reliable pattern such as Mustad 79515 Viking Hooks or Kamasan B950U Uptide should be used. A wire hooklength is also necessary to prevent the tope biting through the line, and a rig body made of at least 80lb line is a good idea to eliminate the possibility of the rough skin of the tope causing abrasion to the line.
Tope primarily feed on fish and these make the best baits. However, tope generally scour the seabed for food, meaning the fish they come across most often are species such as dab, flounder, pouting, poor cod and whiting. Although they do eat mid-water fish such as herring on mackerel on occasion, they do not consume them anywhere near as much as many UK anglers think they do. For this reason anglers using fish not normally associated with bait, such as pouting, whiting and dab can have a higher chance of catching a tope than the more obvious mackerel and herring. A small whiting or pouting flapper, or the centre section of a dab can all produce catches when shore fishing for tope.
Anglers should be under no illusions – catching a tope from the shore is a very difficult undertaking indeed. However, every year there are stories in the angling press of anglers achieving this feat, proving that it is certainly possible.
