SSC - Scottish Seine
A progression from the anchor seine where the net is hauled against the vessels own power rather than an anchor
Scottish seine is a very skilful operation requiring extensive knowledge in locating fish within the grounds, accurate rigging of the gear, and consideration of tidal streams in relation to the gear throughout the shooting, towing and hauling operation. The modern seine net vessel can work anything up to 14 coils of rope each side of the net. Each coil consists of 220 metres (120 fathoms) of lead cored, abrasion resistant rope, from 19mm up to 32mm diameter depending on the size of vessel. One end of the ropes is shot, with a dhan (buoy) attached. The vessel then steams round in a circular shaped course shooting one side of the ropes, one end of the net is attached to the ropes and the net shot away half way round the circle. The other side of ropes is attached to the other end of the net and they too are shot away with the vessel completing the circle close to the dhan, picking it up, leading both ropes to the winch and starting to ‘tow’ the gear. The vessel will tow until strain is on both ropes, then engage the winch to begin heaving slowly. At this stage the vessel is moving slowly ahead, the winch is used to haul the seine net ropes in, slowly at first, and speeding up as the gear is closed up. As the ropes are hauled in, the vessel will gradually start to be hauled astern towards the net even although the engine is still trying to drive the boat ahead. Once most of the ropes are hauled in, the gear is almost closed up and the net is hauled to the stern of the vessel, hauled on board and the cod-end emptied on the side deck of the boat or nowadays into a reception hopper. The gear is ready to be shot away again, and the skipper will take about an hour and a half to three hours.
The efficiency of seine net very much depends on the skipper’s experience and ability to keep the gear square and to get the speed of hauling correct at the various stages, taking into account the weather, the tidal conditions, the behaviour of target species and the depth of water. At one time (1950s to 60s), Scottish seine net was probably the main fishing method in Scotland for demersal fish. At this time, there would have been only a handful of vessels in England using the method; anchor seining was still their favoured method. Over the years, many vessels have changed to trawling, and up to year 2000 there would have been only a few vessels left using Scottish seine in the UK. However, in recent years, there has been a small resurgence in seine netting, with a few new vessels being built specifically for this method of fishing. This is probably because seine netting is a very fuel efficient method of fishing, and it gives the skipper the opportunity to land fish to the market in prime condition, thereby securing top prices on the market. The main areas of operation in the UK are North and North East Scotland, and Shetland, but only by a few vessels. Over the years, many Scottish vessels have turned to pair seining.
