Anchor seine fisheries and fly-shooting

You have a buoy with an anchor and a long heavy rope. The anchor is thrown overboard and you let the rope unreel as you slowly motor away. You then knot a large net to the rope which contains another long rope. You throw the net overboard and motor in a large arch back to the buoy. When you pull in the two ropes simultaneously, the ropes herd the fish into the net. This method is used to catch flatfish and was especially popular by Danish coastal fishermen for a long time. They call this technique 'snurrevaad'. The method is also known as Danish seining.

  • Fly-shooting

    The snurrevaad method is a typical form of coastal fishing. Around ten years ago, this technique was further developed for deeper waters. This adaptation is known as 'Icelandic seining' or 'fly-shooting'. In this case, the fishing lines can be as long as 8 kilometers. The first fishing line is not anchored but is shot into the distance. More and more Dutch fishing companies are starting to use this method for catching plaice.

    Modern anchor seine fisheries are often referred to as one of the better alternatives for the beam trawler with its heavy tickler chains. Anchor seines have much less negative effects on the sea floor than the tickler chains. In addition, this technique costs relatively less energy since no heavy chains need to be towed over the bottom. The experiences from fishermen that use this method confirm this advantage. These fishermen have also found that the quality of the caught fish is much better.

  • Two disadvantages

    This method has two major disadvantages. Sole remains difficult to catch in this way, so that it is not interesting for companies that specialize in sole fishing. Pulse fishing, the sumwing and otter trawling are better alternatives for sole fishermen.
    Furthermore, converting a beam trawler (where the equipment is mid-ship) to a fly--shooter (where the equipment is in the stern) is very radical and expensive. The method is really only suitable for a company that wants to build a new vessel.
