Elephant Fish – Callorhinchus milii – Top Target Species for Surfcasters
Elephant Fish can be caught close to shore in Spring and Summer
Other names for elephant fish: silver trumpeter, reperepe
The elephant fish is rather unusual. A large fleshy cartilaginous trunk protrudes from the snout and together with large wing-like pectoral fins combine to give a rather grotesque deformed appearance. The first dorsal fin has a large sharp folding spine.
The overall colour is a silver-grey with brown blotchy markings. This species is closely related to sharks and therefore has no boney skeleton; instead it has a back-bone of gristle. This means that it provides two large boneless fillets which have for a long time been used in the fish and chip trade. Elephant fish is very good eating.
The odd appearance of the elephant fish would put-off most buyers should they see it whole in their fish monger’s shop window. For this reason the fillets are sold with names like silver trumpeter and silver fish. They are excellent eating.
The elephant fish is rather unusual species related to sharks. Average size 60 to 90 cm. It has smooth skin which is bright silver with dark blotches when first caught. Will take cut-bait but is best targeted with shell fish and grab baits. Strong fighter on rod and line.
Elephant fish are very strong fighters when hooked even on surfcasting gear. They will often swim strongly back and forth before being landed.
Female elephant fish come into the shallow waters of the South Island ‘s east coast between October to November to lay their egg capsules in the sand close to shore. It takes until April for the baby elephant fish to fully develop and emerge from their horny egg case. They do this by escaping down through the narrow passage at one end of the egg capsule that is normally close off by a special valve. At times large numbers of their discarded egg capsules are eventually washed ashore, particularly at Sumner and New Brighton Beaches . I have found these used egg capsules from Amberley to South Rakaia beaches.
They look much like just another piece of washed up seaweed. In the water, they are a yellowish brown colour but darken to black under the sun much like a thin piece of old dried leather. The egg capsules of the elephant fish are almost pear shaped: being round at one end and pointed towards the end with, the escape tunnel. Egg capsules of the carpet shark and skate are smaller and square shaped. In the case of the skate, they have tendrils at the corners.
From April onwards sometimes very large numbers of elephant fish egg cases are washed up on the beaches between Sumner and the mouth of the Waimakariri River making it most likely that the shallow inshore waters of Pegasus Bay are an important breeding ground for this species.
Anglers surfcasting from Canterbury beaches twenty or more years ago were at times able to catch a dozen or more in a day on baited hooks. They are now only caught very occasionally in this way. It is now a good day’s fishing if a single elephant fish is caught in this way. They are powerful swimmers and a large specimen, about 1.2 metres (4 feet long), will put up a spirited fight on rod and reel.
From a video I watched on the internet of an elephant fish filmed underwater they appear to get a lot of forward thrust from their large pectoral fins rather than from their whole body in the way a typical shark does.
Bait for Elephant Fish
Elephant fish are bottom feeders and according to biologists their diet consists almost entirely of shellfish and crustaceans – crabs, and shrimps. They seldom eat fish and when they do only very small ones. Elephant fish don’t often take a hook baited with cut fish fillets. Good baits include pipi, mussel, tuatua and toheroa. Like rig shark elephantfish feed on animals, they find living on or under the seafloor.
Crustaceans like crab and lobster are also excellent bait for elephant fish. Both cooked and uncooked shrimps and prawns obtainable from any supermarket are also good baits for this species. I’d go for uncooked preferably. Possibly the best baits to use are small crabs split open and tied on the hook with bait elastic. If they are too big then cut the crabs in half. Shellfish and crab are probably the best baits for elephant fish that will out-fish anything else. But I have caught elephantfish from time to time on yellow-eyed mullet, and even pre-frozen squid.
A word of warning; toheroa is only allowed to be taken during a very limited season that is declared only about one day each year.
Most of the elephant fish caught by anglers are taken on pipi and tuatua baits, though on occasion they have been caught on squid, octopus and sometimes even yellow-eyed mullet fillets. If you have fished a particular beach for many years and not caught any elephant fish you will be surprised what a difference changing over to crab and shellfish can make. The time of year
Best Time of Year for Elephant Fish
The best time of year to fish for elephant fish in Canterbury seems to be during December and January. However, I have caught elephant fish on the South Island’s West Coast on several occasions during mid-winter.
Elephant Fish are from the same group as the Sharks and Rays
Unlike bony fish, elephant fish are like sharks having no bones; their skeleton is made of cartilage, which although tough and fibrous, it is not as hard as bone. This means you get a considerable amount of firm fish fillets from an elephant fish.
Steel traces are required as the elephant fish has powerful crushing teeth that will soon cut through monofilament. Big hooks aren’t necessary. A size 2/0 being quite a sufficient hook size. Traces can also be tied from heavy monofilament (37kg or 80lb).
The beach at Spencer Park just to the south of the mouth of the Waimakariri River seems to be a very good spot for surfcasting for elephant fish. They are also caught from the beaches of the Canterbury Bight from Birdlings Flat down to the Rangitata River. I’m sure they move about in schools as many experienced surfcasters report that when they have caught elephant fish they sometimes get quite a few at the same time. A mate of mine who has a bach on the south side of the Rangitata River mouth tells me that some evenings 20 or more elephant fish have been caught by him and his mates surfcasting across the road. I suspect they are moving around in sizeable schools.
Elephant fish are by no means confined to Canterbury. I have caught them on the West Coast of the South Island as far south as Haast. Elephant fish are strong hard fighters even when hooked on heavy, surfcasting tackle. They swim strongly up and down the beach when hooked.
