The Dutch had a near monopoly of the herring fishing from the 15th to the 17th centuries. The boats, called busses, were very large. They lay overnight with the drift nets set to catch the herring and were hauled by hand in the morning. The herring were salted and placed in barrels. These barrels were then transferred to small boats called jagers which were tenders to the busses. These boats took the fish to the markets.
The 18th century saw some Scottish fishermen emulate this Dutch method of fishing. In 1718, the government introduced the bounty system to promote large scale fishing. This meant that the government paid a bounty to the boat owner based on the tonnage of the vessel and would also pay a bounty to anyone for simply building a fishing boat. This continued until 1820 and did much to encourage the growth of the fishery. The fishery was valuable and the fleets often came under attack from French and Spanish privateers. Because of this, armed ships were employed to accompany and defend the fishing boats. Despite this, the Dutch style of fishing didn’t produce the results the government wanted. The bulk of the Scottish fishery was still using the line and bait method in inshore waters. However, in 1785 the government instituted barrel bounties which meant that the bounties were payable based on the amount of cured herring produced. This encouraged the herring curers to enter into contracts with the fishermen whereby they would be guaranteed a price for their catch.
The 19th century saw the greatest growth in sea fishing on the Scottish east coast. In the early years of that century the boats were very small, made of wood and were either one or two masted. They were not expensive to build and small repairs were carried out by the fishermen themselves. These early boats needed to be light so they could be dragged up the beaches.
The fishermen did not venture far from the shore as these boats were undecked and unstable under stormy conditions. In 1848, a violent storm hit the country and 124 boats were sunk, and 100 fishermen lost their lives. The government appointed Captain John Washington to enquire into the disaster and to make recommendations (the Washington Report). He pointed out that the boats were too small and being without decks prone to water inundation. However, not all of the fishermen were happy about larger decked boats. They felt that heavier boats would be harder to row and decks would make it easier for men to be washed overboard. Also beaching the boats would be impossible. But a good many fishermen took a contrary view and felt that the decked boats was a good idea. They realised that the boats could fish further from the shore and would be better in storm conditions. Larger boats could hold more fish and so profits would be greater. The first decked boat was built in Eyemouth in 1856 and this soon became the norm for the Scottish fishing fleet. These sail boats were of three main types: Skaffies, Fifies and Zulus. Common to all three types were the lugsale, hence their name - luggers. The need for the larger boats spurred on the building of harbours all along the east coast, in the 1850s and 1860s. This heralded an enormous change in the size of the herring fishery. Initially, the market for the pickled herring was Ireland and the West Indies where it was fed to slaves. The market received a setback in the 1830s following the ending of slavery on British-owned plantations and, from 1845 to 1851 when the Great Irish Famine forced a mass emigration from Ireland. However, improvements in curing techniques produced a superior product and soon meant that new markets opened up in Russia and the Baltic countries.
The fishermen, with the support of the curers, invested in larger boats and additional nets. The fleet grew quickly but was still could only fish for herring during the two months when the fish were off the Scottish east coast. By 1880, there were around 7,000 Scottish boats involved in herring fishing so the fishing season needed to be extended. This led to a migration of a sizeable amount of boats and curers to the west coast in May and June. By 1880, the numbers of boats fishing the west coast numbered more than 1,000. In the 1860s, Scottish boats were also to be found in East Anglian waters for the Autumn fishing. Initially, Scottish curers were not present in any great numbers in this fishery but by the end of the 19th century large numbers were represented in Great Yarmouth and Lowestoft. By this time, the Scottish fleet actually outnumbered the local one. The curers soon turned their attention to Shetland for the early summer fishing causing the local Shetland fishermen to adopt the drift net and larger boats. By the early 20th century, more than 1,800 boats fished the Shetland waters.
In 1884 the herring industry faced a crisis. The curers wanted an end to the contract system because they could not balance quantity and costs with market conditions and so wanted a move to an auction process. Fishermen wanted the status quo but reluctantly agreed and from 1887 the herring were auctioned.
The peak of the herring fishery industry and also its main decline came between 1900 and the First World War. Steam-powered fishing boats appeared towards the end of the 19th century and it was steam drifters that would take the volume of the catch to new heights. The powered winches allowed longer nets to be deployed and their speed enabled the boats to get to market quickly and to return to sea. In those early years of the 20th century, the Scottish catch reached 2 million barrels annually. Before the First World War, Germany and Russia were the main market for British herring. After the war, however, Germany was racked by inflation and was impoverished. Russia underwent the 1917 Revolution and civil war. Other European countries started to compete strongly with the British fleets and for twenty years the industry went into a steep decline. The beginnings of the seine net fishing began in Scotland in 1921 but the use of the large inefficient steam boats greatly hindered this new whitefish fishery. After the Second World War, the Scottish east coast fleet, with government assistance, was totally regenerated becoming mainly a whitefish industry. This in turn declined in the 1970s and 1980s due to overfishing and the subsequent imposition of quotas by the European Union. The herring industry continued to shrink. From the 1960s, trawling and purse-netting were the main methods of pelagic fishing which not only includes herring but also mackerel. Although a quota is placed on the total herring catch and with no limit on mackerel, this sector is now the healthiest in the Scottish fleet.
The Norsemen were skilled seamen and boat builders and their boat designs depended on their needs. Trading vessels were wide to allow large cargo storage while raiding boats were long and narrow and very fast. They all used the clinker fashion of planking, i.e. the planks overlapped one another. The boats used for fishing were scaled down versions of their cargo boats. The Scandinavian influence impacted on boat building long after the Viking period came to an end. Yoles from the Orkney island of Stroma were built in the same way as the Norse boats. Early Scottish boat builders copied the Scandinavian designs with their clinker planking and characteristic sharp stems and sterns.
The "Fifie" then became the predominant fishing boat on the Scottish east coast. They were used from the 1850s until well into the 20th Century. Fifies had a vertical stem and stern with a broad beam, which made them very stable. Their long keel was a disadvantage especially manoeuvring in confined spaces. These boats were two masted with a main dipping lugsail and a mizzen sail. The masts were set quite far forward and aft to release a good working space. Fifies built from 1860 onwards were all decked and from 1870s onwards the bigger boats were built with carvel planking, i.e. the planks were laid edge to edge instead of the overlapping clinker style of previous boats. Some boats were now being built up to about 70 feet in length and were very fast.
The Zulu boats were built to the carvel method of planking which was much stronger than the clinker system. The shape of the Zulus gave the boats a long deck but a shorter keel which greatly improved their manoeuvrability. Zulus were two masted boats and carried three sails - fore, mizzen and jib. The sails were very heavy and difficult to haul and the masts had to be very long and strong. Masts could be 60 feet tall on boats of 80 feet in length. Their design produced very fast boats that became invaluable to herring fishing fleets. They got to the fishing grounds quickly and returned swiftly with the catch. Because of these qualities, the Zulus rapidly became very popular along the entire east coast. As the 20th century approached, steam capstans were introduced and this made the hauling of the sails and nets much easier for the crews. One of the best of those were the capstans patented and built by MacDonald Brothers of Portsoy, in 1908.
Steam fishing boats had many advantages. They were usually about 20ft longer than the sailing vessels so they could carry more nets and catch more fish. This was important as the market was growing quickly at the beginning of the 20th century. They could travel faster and further and with greater freedom from weather, wind and tide. Because less time was spent travelling to and from the fishing grounds, more time could be spent fishing. The steam boats also gained the highest prices for their fish as they could return quickly to harbour with their fresh catch. The main disadvantage of the steam boats, though, was their high operating costs. Their engines were mechanically inefficient and took up much space while fuel and fitting out costs were very high. Before the First World War, building costs were between £3000 and £4000, at least three times the cost of the sail boats. To cover these high costs, they needed to fish for longer seasons. The higher expenses meant that more steam drifters were company owned or jointly owned. As the herring fishing industry declined, steam boats became too expensive.
Petrol and paraffin engines began to be used in 1906. At first, they were mainly fitted to smaller boats of between 18 and 30 feet in length and they provided auxiliary power to assist the sails. However, as diesel engines became more powerful, the sails were replaced all together and the engines were fitted in larger and larger boats. Motor engines were relatively cheap, making them affordable to individual Fishermen. Early engines cost less than £100 and fuel costs were low. These boats also needed less maintenance than steam vessels. The two most popular engine brands were the Gardiner and Kelvin engines. The compact engines meant they could be fitted to existing sailing drifters such as Fifies and Zulus. The traditional Fifie style was better suited to the installation of a motor, which led to the custom building of a number of modified Fifie design boats with motors.
In 1920, though, the government changed the rules by removing the guaranteed price for the herring and prices dropped dramatically. In 1921, some Lossiemouth skippers noticed that the Danish seine net boats were landing huge quantities of plaice and other white fish at the English east coast ports. Their interest resulted in a few buying some seine nets and winches and trying this form of fishing. As they perfected seine net fishing, more of the Lossiemouth fleet converted to seine net. But boat design for this type of fishing was still proving to be an obstacle. That, and the cost of the majority steam boats prompted a new style of fishing boat. John Campbell, nephew of William Campbell who designed the first Zulu boat built a wooden boat that resembled, to some extent, the "Fifie" but had a broad beam. His boat, the Marigold, did very well and over a relatively short period the entire Lossiemouth fleet (the first in Scotland) converted to the seine net. Other east coast ports followed on very quickly.
Today, trawl fishing is the main industrial method of catching white fish. These trawlers and can catch and store massive amounts of fish. They possess highly sensitive electronic equipment and remove the chance element from fishing. They operate by trawling the nets along the sea bed where the kind of fish they want to catch are located.
This the commonest of the towed fishing gear; it is also known as ‘’otter trawling’’. Trawl nets are shaped like a funnel with the sides extended ahead to guide the fish into the net. Otter boards (sometimes called "doors") spread the towing wires and keep the net open horizontally. The mouth of the net is held open vertically by the use of floats attached to the headline, while weight distributed along the ground rope allows the net to make good contact with the sea floor. The otter boards would scrape along the seabed making noises that attract fish. The fish would congregate between the boards keeping up with the them until they tired and the net would then overtake them. This method is used mainly to catch the demersal species such as cod, haddock, whiting and flatfish. The boats themselves can be less than 10 metres in length for inshore fishing to 60 metres or more for deep sea fishing.
With the decline in the volumes of roundfish, the growth in fishing for high-priced species such as monkfish and flatfish is being seen. In this case, scraper trawls are used. The nets are shaped differently with a lower headline, longer wings allowing a greater area to be swept.
Scottish seining, sometimes called fly dragging, has the net attached to two long ropes usually made of leaded polypropylene and around 3 km in length. The net is deployed in a triangular fashion with the first rope attached to a marker buoy, the dhan, to which the boat returns to complete the set. Both ropes are then winched in as the boat steams ahead slowly. Winch speed is gradually increased as the net gets closer to keep the net moving forward and also to herd the fish into the net. Like the trawl, floats and weighted footrope keep the mouth of the net open and in contact with the seabed. This method of fishing takes place on grounds on the continental shelf and not in deep sea. Seine netting is for all forms of whitefish.
The beam trawl is one where a beam, up to 12 metres in length, is attached to a skid at each end. The beam is situated on top of the skids effectively keeping the top of the net open and the fish are channelled between the skids. Two beam trawls are deployed alongside each other from outrigger booms on each side of the boat. This method is primarily for taking flatfish but these vessels can be used also for scallop dredging.
