The ragworms wedding as it is known, is called the springs most exciting adventure for the sea trout fisherman. And if you are lucky enough to be at the right place at the right time, there is no danger for you not connecting with fish. Although ragworms are on the sea trouts menu the whole year round, its in the spring under the annual swarming that the sea trout will go on a feeding frenzy and gorge themselves on the worms.
There are many patterns known to sea trout fishermen to imitate the worm, some better than others, some simple to tie and some, not so simple to tie. I believe the original pattern from the tying bench of innovative Swedish fly tyer Robert Lai is still for me, without a doubt the best. Robert´s pattern is probably one of the most challenging patterns, many fly tyers will ever learn to tie, but the rewards are great. No other worm pattern swims and pulsates in the water like his, imitating the natural swimming worm as closely as humanly possible with feather and steel.
Although we are not 100% sure, and thats not for lack of theories! But the spring swarming is due to the worms spawning season and seems to be triggered by two main factors. A rise in water temperature 6-7 degrees, and the arrival of a new lunar phase, (full moon) from anywhere around mid March and into April. The female ragworm broods her eggs within her long flattened body and as the eggs develop her body becomes brittle and eventually splits, releasing the eggs. The male ragworms are attracted to the egg laying by following pheromones, that are also released by the females. After spawning, both male and female ragworms die.
Ragg worm swarming can be very local in most situations, and it’s not easy to know where. Then you should look to the sky, beacause the greedy and forever hungry sea gulls can show you the way. If you can see that screaming sea gulls are flocking and circle around a area of coast, this shows you where to fish – just like the pelicans when tarpon fishing. Consider also when the strong spring sun has been high in the sky all day and warming up the shallow’s, especially with dark muddy bottoms. Most sea trout fishermen, including myself, prefer sight fishing during the day looking for rises as you fish systematically, possible holding spots in small bays and inlets as the tide rises and falls. But if you are, as most sea trout fishermen, hoping to connect with larger fish that are normally wiser and more sceptical about entering the shallower coastal waters during the hours of daylight. These shallow areas retain the days heat during the first couple of hours of darkness. It’s during this period that larger sea trout dare to venture into the shallows to feed. You should fish at least a couple of hours into the night.
The pattern I have tied here started off, 15 years ago, as a direct copy of Robert´s original pattern, but over the years it has changed a little, but this had more to do with receding memory on my part, than anything to do with developing the pattern. But the basic original principal is still there and the pattern still works. There are a few rules one must follow when tying this pattern. The tail hook should be small and light in weight. Because the worm has an extremely flexible body, a larger and heavier tail hook has a tendency to “Hang-up” on the body under casting, which results in you fishing a ball of marabou with the hook out of-line. A heavier tail hook also reduces the animation and swimming motion of the worm by restricting the tail from lifting when the bead head sinks. Another point is the central core of the fly, not the loop that you spun the marabou onto but the Dyneema spine that holds the front hook to the tail hook. This is Alfa and Omega regarding the success of tying this pattern. If the spine is not securely attached to the front hook, you can risk loosing, not only the business end of your worm but also fish. So make sure that you tie this in as well as you can and don´t be afraid to use super glue. The Latin name for the common ragworm is Nereis diversicolor, meaning they are quite variable in colour, but typically reddish brown and turning more on the green side during the spawning season. So the rule for colour is that there is no rule, you can tie the worm in any colour you like! Personally I have found the two most successful colours for me are the one shown here and bright orange. And don´t forget that ragworms are on the sea trout menu the whole year, so don´t restrict your fishing with it just to the spring, it´s also a deadly pattern for regular trout fishing.
