My favourite species of fish to target on light tackle in estuaries, using artificials has to be the River Snapper. I have the utmost respect for this fish, he is without doubt the most challenging of our estuary species in Southern Africa, and worthy of the respect given to him by anglers around the country. I thought I would write a bit of a tribute to this species, including some of my thoughts on catching them, some facts about them and throw in some pics of these magnificent fish that I have got in my picture library.
Their scientific name is
Lutjanus argentimaculatus But these fish go by a number of common names. Rock salmon, River roman and Nkulunkulu are some of the names that River snapper go by here in South Africa. Nkulunkulu is actualy the same name that the Zulus and Xhosa use for God, so this shows the respect that these people have for this species! In Australia they are called Mangrove Jacks.

River snapper have to be one of the wiliest fish in any salt water river sytem, they are notoriously difficult to catch at times, as they will stubornly refuse any offerings when they are not in the mood to eat. I once made at least 50 casts to a piece of structure, knowing that a river snapper must be hiding beneath it. I tried just about every lure in my box, yet there was no sign of the snapper. A small kingfish then hit one of my lures and I started pulling him in, suddenly there was a massive boil on the water's surface and a flash of deep copper as the stubborn snapper finally came out of his lair and had a go at the struggling kingie. He had been there all that time, watching my lures and refusing them, but couldn't resist the temptation of the little kingfish!

It is for their cunning that River Snapper are well known, as well as for the agressive smashes that they do make when they decide to eat a lure. They basically turn on the lure and hit it going back to their lair, making a big swirl and hitting extremely hard as they accelarate in the opposite direction. They are extremely dirty fighters, and will cut you off in a flash given half a chance. They live in foul structure, and the fight is often over before it began, with the bemused angler holding a rod with a limp piece of line hanging from it.
River Snapper seldom venture far from their chosen structure during daylight hours, preferring to hold up where they feel safe, and will rush out and ambush any passing prey which comes close enough for them to attack without moving too far from the security of their homes. They are predominantly nocturnal feeders, as you can see by the large eye, which is an adaptation for hunting in the dark. This species will roam around the river system at night, often moving right out over sand and hunt for its prey. They like to feed on crabs, shrimp, fish and just about anything else that moves in the water, whether it be on the surface, the midwater or right on the bottom, when they are in feeding mode.

River Snapper will use just about any structure as cover, depending on the availability in the river that they inhabit. The more prime the location ( better structure) will generally have the bigger fish, while the smaller fish will be left with whatever cover they can find. These fish are highly residential, and will inhabit the same spot for years. They are not territorial in the strict sense of the word, however, and if the structure can hold multiple fish, then they will live there in groups. A bank of submerged mangrove roots for example may hold hundreds of fish in a fairly small area. They create an underwater maze, which the fish can swim in and out of, giving them complete security and cover. I have snorkelled amongst mangrove roots in a large estuary in Kenya and was amazed at the density of river snapper in a small area, all appearing to live in complete harmony with one another.

In estuaries where there are not mangrove roots they will use different structure as cover. Reedbeds are a good place to find river snappper in many of the KZN and Zululand systems. The River Snapper will live along the edges and within the stands of Phragmites reeds, where there are gaps below the water's surface for them to move in and out of cover. Along rocky banks where trees hang low over the water is a favourite in Transkei estuaries. Below cliffs or ledges, where there is deep dark water is another favourite haunt of this species in the Eastern Cape rivers. Bridge and jetty pilings create good structure for river snapper, particularly if there is a deep hole scoured out where the piling enters the sand on the river bed.
These fish are highly adaptable, and can survive in almost any river system. They are tolerant of a wide range of salinities, from totally fresh water, to sea water. I have caught them in the upper reaches of rivers in Mozambique amongst the water lilies in fresh water, more than 40km from the river mouth.

Above is a river snapper caught along the edges of bulrushes at least 30km from the river mouth in totally fresh water in the Govuro river, Mozambique.
This adaptability, along with the fish's natural cunning makes it a real survivor. In mammalian terms I would compare it to a leopard. It is one of the few species of predatory fish that continues to be successful in some of the badly silted up and polluted river systems of the KZN South Coast, for example. It can survive in a river system that is totally cut off from the sea for years, and will exist in places where you would not believe it possible for such a fish to live. This makes it special in my book, and also means that the challenge of catching these wily fish does exist for those of us who have the patience and perseverance to stalk them in the waterways which are ignored by most anglers.
Catching river snapper requires stealth, above all else. In the above pic you will see the electric trolling motor, which makes it possible to sneak up on likely spots and cast to the fish without advertising your presence.
These fish can be targeted in a variety of ways, and many will be succesful on different days. The traditional way of catching River Snapper in KZN is with live glassies or mullet. I like to fish with artificial lures, however, so I will be talking about fishing for them that way here. Being predominantly nocturnal, most activity will be during the hours of dawn and dusk, when the fish are still in, or getting into feeding mode. Successful snapper fishing means waking up early and being on the water in the dark, and being the last off the water in the evenings. Even better, if you are up to it, is to fish well into the darkness, which is never easy, but can produce great results.

One of the most satisfying ways of catching River Snapper is on topwater lures. Almost any lure worked slowly along the surface in the right zone has a good chance of getting eaten at the right time. There are some favourites though, that have worked well for me over the years. Rapala Skitter Pops, Storm Chug Bugs, mirrOlure 7m's, and Rapala X-Rap Walk lures are amongst my top performers when it comes to catching River Snapper on surface lures.

Apart from the visual impact of the spectacular smash of a snapper hitting a slowly worked surface lure, it is also a very effective way of targeting these fish for a couple fo reasons. Firstly you can get the lure right over the most foul of structure, but it will not hang up, as the lure stays on the surface. Secondly the snapper has to leave the safety of his lair to eat the lure on the surface and you have more time to turn him and get him away from the structure before he cuts you off.

It is crucial to use tackle that can turn a snapper, before he gets back into his structure, but at the same time you want to be able to cast light surface lures. Braid has made this possible. A fairly light rig with a strong drag and 15 to 20lb braid is generally ideal. I like to use a leader of 30lb fluorocarbon, as this material has the best abrasion resistance and is most likely to survive getting scraped against rocks, branches and mangrove roots. Very often the structure is covered in small barnacles, mussels and sun oysters, which will cut through line in an instant when the line is under tension.

Another succesful method of targeting river snapper, is to use diving lures or soft plastics. I have found that soft plastic minnows, texas rigged, bass style can be very effective. This method has the advantage of being weedless, and you can cast the lure right into the structure. You need to have your wits about you though, for when the snapper hits, you need to strike very hard. This is firstly to set the hook through the plastic of the lure into the fish's jaw, and secondly to take advantage of the element of surprise and get him away from the structure before he is aware of what is going on.

Some of the diving lures by Rapala also work well. I have had great success with Rapala X-Rap lures, twitched around at the edge of the structure, or over it.
