G. VAN TIENHOVEN. Zoölogical Station at Den Helder. ("Wonderkuil'' in foregronnd). FISHERIES IN THE NETHERLANDS BT P. G. VAN TIENHOVEN. HPHERE is no pretence at completeness in this sketch of the J Netherlands Fisheries. It is intended to give no more than a slight idea of this branch of national prosperity, so vitally important for The Netherlands, and to attract the readér's attention to a few sahent points, which will give him an impression of what the fisheries mean to this country. The water has ever been The Netherlands' greatest friend and foe, andone glance at the map convinces us that next to Navigation, Fisheries were bound to constitute a source of prosperity. The North Sea encloses The Netherlands on two sides (on the North and the West), whilst in the country itself there is moreover the Zuyder Zee, cövering an area of 357.000 H.A. (below Wieringen). This latter consists of brackish water and is of great importance for the enticing and catching of anchovies and other kinds of fish. Canals and rivers intersect the land, and in many places we find lakes and ponds, though the number of these has been greatly reduced by means of impol dering and draining. These diked-in polders testify to it, that The Netherlands justly bears the name of "waterland". HISTORY. Most prominent in the History of the Fisheries is the Herring Fishery, also called the Great Fishery, for the protection of which numerous measures were taken in the 16th century and after. This trade was introduced into Zeeland from Flanders; in 1163 the first herrings were caught and eaten in Holland. A radical change was brought about in the Great Fishery by the invention of sousing in the first half of the 14th century by Willem Beukelsz op 3 Biervliet. By this process the gills and other internal organs are removed the moment the herrings are caught; they are then packed in barrels, between layers of salt. This sousing-process enables the Netherlands fishermen to go on with their work at sea, without having to put back to port after every catch, as the English fishermen do, who work so much nearer their base of operations. The importance of the herring fishery, — 'sLands Principaele Goudmijne 1 as the old writers are fond of calling it — may be judged from the prosperity and wealth of the towns where this trade was carried on. Enkhuyzen, now one of the "villes mortes" of the Zuyder Zee, yet bears unmistakable traces of its former wealth, grandeur and prosperity, at a time when it ranked among the foremost fishing-towns. The stately town-hall, completed in 1688, vividiy remmds us of the time when a neet of 500 fishing smacks set out from this town alone. Truly, Enkhuyzen's coat-of-arms, three herrings, one above the other, is well-chosen and appropriate. In its golden days Enkhuyzen counted 40,000 inhabitants, which number, after the decline of the fishing-trade in Coat-of-arms 1840, was reduced to 4988! (To-day the of Enkhuyzen town has some 7000 inhabitants.) It was a fête day when the first of the "New Herrings" came ashore, and the old saying, "Haring in 't land Dokters aan kant." 2 proves that, besides the economie advantages, the nutritive value of the herrings was also highly prized. Down to this day the fishmonger's shops are decorated With flags and evergreens as soon as this delicacy is on sale again. In the 18th century the herring-fishery began to decline, and in 1747 the number of fishing-smacks, which in 1601 amounted to 1500, had come down to 200. By means of 1 The Chief Goldmine of the Country. 2 Herrings in the land, no doctors needed. 4 The town-hall at Enkhuyzen. View at the "Amsterdam train-oil boiliiig establishments" on Jan-May en-Is] and (1639). premiums of f 500 per vessel, to be awarded for 12 years, an attempt was made to keep the failing trade going; but with no great success, for at the beginning of the 19th century the herring fishery feil off even more, and in 1813 only 3 smacks put to sea. On the restoration of the independence of The Netherlands, the trade once more began to fiourish. In 1814, 98 smacks put out; in 1830, as manyas 173. Then followed a fresh decline, until in the middle of last century there was a revival of the sea-fisheries which brought that flourishing trade to the prosperity it enjoys at the present day. The old "Krahntor' at Dantzic, where in the middle ages the Hollanders had their own herring-stores. Whale-fishing, the so-called "Little Fishery", sprang up in the 17th century side-by-side with the herring fishery, and quite suddenly attained extraordinary prosperity. It was centralized in the "Noordsche Compagnie", which, established in 1614, consisted of "chambers" of the various 7 towns, carrying on the trade as a trust, or union of independent organizations. The actual purpose of the establishment of the "Noordsche Compagnie" was mutual cooperation, which would enable the trade successfully to cope with foreign competition, and if possible to oust the foreigner from the world mark et, numerous disputes having arisen from time to time with England and Denmark, regarding the right of the Hollanders to fish far up in the North The members of the Compagnie continued to have independent control of their own capital, and to fit out their own fieets. Annually they canie to a mutual agreement as to the quantity of whalebone and train-oil they meant to obtain. The village of "Smeerenburg", a settlement on Spitzbergen, where the men wintered and stored their tools, had grown to a place of importance within the course of a few years; in 1633 it even possessed a church, and a fortress for defensive purposes. In 1645 the Compagnie was dissolved owing to lack of interest, and Smeerenburg ceased to exist. Besides w hal es, this trade included the catching of walrusses and seals; howconsiderabletheresultsoften were, may be seen from the number of whales which an Amsterdam whaling-fleet caught in the year 1684, no less than 1185. After the dissolution of the Compagnie whale-fishing was continued by private enterprise with intermittent success, off Greenland and about Davis Strait. The 14,167 vessels which put to sea after the Compagnie had ceased to exist, yielded a total of 44J million guilders. Towards the end of the 18th century, however, the industry began to decline, and in 1864 the last whaler, the Dirkje Adama, was sold at Harlingen. In 1869 another attempt was made by Mr. C. J. Bottemannb to establish a Whaling Company, but the venture went into liquidation in 1872. FISHERY LEGISLATTON. Whereas sea-fishing attained comparative prosperity in the 2nd half of last century, fresh-water fishing, in rivers, canals etc, slowly decreased, chiefly owing to the fact that 8 Loading nets for a herring-trip unauthorised fishing in private waters, though prohibited, was punished only by the lightest of penalties, (not as a crime, but as a trespass). A more adequate regulation of the Fisheries was repeatedly pressed for, and the fishers themselves eagerly looked forward to fresh legislation. The Act of June 21st, 1881, contained regulations regarding sea- and coastal-fishing, and also regarding fishing in the Zuyder Zee and the Zeeland streams, fresh-water fishing being regulated in the Act of 1857, along with the chase. This state of things was brought to an end by means of the new Fisheries Act, which after endless difficulties and lengthy preparations was enacted on October 6th, 1908, and came into force on July l8t, 1911. For the first time, all the fisheries Were comprised in the one bil], being èlassified as : I. Sea-fisheries. II. Ooastal-fisheries. III. Inland-fisheries. This Act institutes & Fisheries Board, in which has been merged the former Sea-Fisheries Board. This Board gives advice independently, or acts as advisory body in cases where the Government consults it regarding the true principles of conduct for Government intervention in thisbranch of national prosperity. The work of the former Adviser in fishery matters, and of the former State institution for investigation at sea, has been entrusted by Decree of May 10"' 1912 to a State Institute for Fishery Investigation, which furnishes scientific information on all matters concerning the fisheries. Following the example of other countries, a newsphere of activity has been created by the introduction of a system of Inspection. Officials are appointed to supervise the fisheries, to enforce the carrying out of the enactments, to serve as technical helpers and advisers to those employed in the fishing-trade, and to investigate how and by what means the fisheries can be promoted. This work covers a wide range, and in the first years of its establishment the service errew to a ereat number of officials. 11 I S E A-F IS HERI ES. From an economie point of view this branch of the fisheries is by far the most important. Itiscarried oninthree different ways: 1. Drift-net fishing for herrings. 2. Long-line fishing. 3. Trawl-net or trawl-fishing. Drift-net fishing. The herring fishery is carried out by means of drift-nets, 100 or 150 of which are fastened together, often to a length of 3 to 4 K. M. (This is called the "Vleet"). Towards the middle of last century a great improvement was introduced by the shipowner A. E. Maas of Scheveningen, who substituted light cotton nets for the heavier hemp nets, and who copied the French type of lugger, which was found to be far more serviceable for the fishing-trade than the old smack. Even to this day the herring fishery remains the most important branch of the sea-fisheries. In 1913 it formed 74.52 % of the total catch of salt-water fish for that year, the profit representing 69.59 % of the total yield. As the type of herring-vessel got larger, the old seaside towns, where in winter the smacks were laid up on the beach, as for example Zand voort, Scheveningen, Noord wyk, Hellevoetsluys and Katwyk, no longer came up to the requirements. Special harbour accomodation was needed; in 1899 Scheveningen got a fishing-port, which was completed in 1905. The plans for the extension of the inner harbour at Katwyk are awaiting execution. The need of centralization for the sale and despatch of fish was likewise feit, so that those harbours that were easily accessible, and had sufficiënt depth, soon attained greater importance, as the vessels from other ports could come in and land the fish there. The major, part of the herring-Heet is concentrated in 5 ports, to wit: Katwyk, Maassluys, Scheveningen, Vlaardingen and Ymuyden; and in 1913 the number of their craft amounted to 72% of the whole fleet, representing 89 % of the total tonnage. 13 r | Harbour at Maassluys.

In 1913 this amounted to 7,107,198 K.G., with a profit of fl. 576,641, as against 2,960,835 K.G. (fl. 235,444) in 1912, and 740,775 K.G. (fl. 75,032) in 1911. In 1914, on account of the war, only one English drifter came to the Ymuyden market, so that the supply of fresh herring and mackerel from foreign vessels in 1914 was only very small. The smaller fishing-boats are gradually disappearing; in 1913 there were only 119, and in 1914 only 64 boats of the old type left. Luggers took their place, — as it was difficult to engage crews for them — the men preferring to serve on the larger boats, which moreover allow the fishing-trade to be carried on more economically. In 1913 the herringfleet totalled 751 boats, the cubic contents being 182,184 M3; in 1912 it was 741 boats, with 174,028 M3. contents, whereas in 1892 the number had been 546, with 83,451 M3. contents. It is curious to observe how little mechanical means of propulsion have sofar been applied to herring-fishing, far less than in trawl-fishing, and that the former trade is carried out mostly by means of sailing-boats, which in the trawlfishing trade have already been replaced by steamboats. 15 _ ; Fislimarket at Vlaardingen. In Vlaardingen, however, steamboats are beginning to be used, since the construction in 1896 of the first steamer for Mr. A. Hoogendijk Jzn., and the practice is growing as these boats have proved to be adaptable for long-line fishing in winter, as well as for herring-fishing in summer. Long-live Fishing. This is carried out by means of long lines, anchored to the bottom of the sea, and branching off into shorter sidelines furnished with hooks, to which the bait is fastened. These so-called "lines" are often as long as 12 K.M. Long-line fishing is a trade which is decreasing every year, and which is now being carried on mainly as a side industry in spring and autumn, along with drift-net fishing. Most long-line fishing-boats engaged in the main trade are registered in the three towns of Middelharnis, Maassluys and Pernis. From 50 vessels in 1892, the number feil to 12 in 1913, and to 6 in 1914 ! . With the line are caught mainly: Haddock, cod, halibut, ray, and ling. Haddock and cod constitute 78 % of the total supply, and represent 88 % of the total profit. Trawl or trawl-net fishing. This is carried on by means of trawl-nets which are dragged along the bottom of the sea. The development of this trade is closely connected with the immense rise of Ymuyden as a fishing-port. In the course of a few years it has become the largest in the European continent. Only England has larger fishing-ports, like Grimsby, Aberdeen and Huil. Its situation at themouth of the North Sea Canal, and in close proximity to Amster- supply of long-line fish. 1912 1913 1914 2,049,413 K.G, 1,530,980 „ 890,602 „ fl. 604,626 „ 539,667 , 317,332 17 Scheveningen fishing boats on the shore before the fishery-harbour had been constructed. dam, enables Ymuyden to despatch the fish by water as well as by the main railway-lines. It has Germany as hinterland, ^,nd daily despatches enormous quantities to the Rhine province and Belgium. Ymuyden owes its existence and its rise to the construction of the North Sea Canal, which directly connects Amsterdam and the Zuyder Zee with the North Sea. In 1865 the work of construction was begun, and on Nov. 1**1876 the Canal was inaugurated. Ymuyden at that time was far to seek, and now it nurabers more than 10,000 inhabitants! With truly American rapidity it is growing into a town of importance, leaving the town of Velsen, under administration of which it falls, far behind in development. Originally the fishing-boats entered Ymuyden as a refuge, and lay sheltered in the canal. When however the locks were extended, and the increasing fishing traffic blocked the entrance to the harbour, there was no longer room for the fishing-boats, so in 1887 the Government decided to make a special harbour for fishing-boats, which was inaugurated in 1896. The depth of the canal and harbours renders it possible for steamboats to carry on the fishing trade; as early as 1901 the harbour had to be enlarged, and it now covers an area of 13 HA.! The anchorage, which is now being constructed, will cover an area of 3,5 HA. The catch is taken to three tish-markets, situated next to the railway, the markets even being provided with a special despatch-station of their own. The auction is conducted by the Government. Thus the State remains liable for the purchasers, but the liability, in virtue of a contract between the State and some Banking firm, is taken over by the latter body. At the other ports the fish-auction is not a Governmentinstitution. There the auctions, though public in name, are conducted by the ship-owners' societies or by the municipalities themselves. The rapid development of Ymuyden may be judged from the number of ships entering the harbour: 1897: 9,794 vessels with 690,507 M3. total contents, average content 70.5 M3. Of these 68 were steam-trawlers, and 8,872 trawl-fishing sailing-boats. (6981 coastal-fishers.) 191é: 13,598 vessels with 3,358,125 M3. total contents, 19 average content 246,50 M3. Of these 4514 were steam-trawlers and 6314 trawl-fishing sailing-boats (4666 coastal-fishers). 255 of them were long-line fishers and 349 drift-net fishers, whilst 2,166 were cargo-boats for the transport of fish. The number of foreign vessels, xnostly English, is considerable: in 1913 it amounted to 338 steamboats (333 of which were English) and 46 English sailing vessels. Next, a few items conceming the total supply of fish at the Government market: 1900 fl. 818,970 1905 , 4,072,666 1911 „ 5,379,029 1912 . 6,974,394 1913 , 6,995,785 1914 | 7,134,466 1«* 9 months of 1915.. „ 10,388,148 The increase from 1912 to 1913 is comparatively low on account of the fishermen's strike in November and December 1913. The greater part of this fish is for export In 1913 the water-carriage amounted to 7,064,285 K.G., in 1914 to 7,009,040 K.G. The export by rail from Ymuyden in 1913 was: 34,391,926 K.G., in 1914 35,503,241 K.G., and the proportional percentage for the 5 countries of destination was: The Netherlands. Germany. Belginm.

Only a small quantity of certain kinds of fish is consumed in The Netherlands, where so far fish cannot be called a "national dish". The war, however, has caused a rise in the price of meat, and so the " Central Bureau for the sale of fish", called into being by the abnormal state of affairs, is trying to meet the exigency by introducing fish as a cheap food for the people. In 1915 the municipalities of numeroüs toWns established markets or shops for the sale of fish. TRAINING FOR THE FISHING-TRADE. In 1913 and 1914 the number of men employed in the sea-fishing trade amounted to about 12,000, including some 1000 hands serving on vessels engaged in coastal-fishing as well as sea-fishing. Fishery-Schools exist in twelve towns: Enkhuyzen, Harderwyk, Hindeloopen, Katwyk-on-Sea, Maassluys, Marken, Noordwyk-on-Sea, Scheveningen, Spakenburg, Vlaardingen, Volendam and Ymuyden. A fishery-course ismoreover conducted by the School of Navigation at Helder. Most of these schools are municipal institutions, others have been 25 Harbour of Ymuyden with fish-auction-buildings established by different Societies, all are endowed by the State and the Province. On the whole however, the instruction leaves much to be desired as yet, and is not conducted on the same basis and lines of development as in England. At the Fishery-Schools the men are principally taught to navigate their vessels, they learn the rudiments of navigation, and the repair of fishing-tackle, whereas it would be advisable rather to instruct them in the handling of the fishing-tackle, in the life and habits of the fishes, and the way to deal with them afloat and ashore, in the most rati- . t'ishery-school with a number of pupils at Maassluys onal method of exploiting the fishing-waters, in the economics of the fishing-trade, and in fishery-legislation. Not long ago a bill was introduced into theStates-General,regulating the professional instruction, and dealing also with the Fishing-trade. The appointment of an itinerant Fishery Instructor is being likewise discussed, and in the State budget for 1915 a sum has already been set aside for his remuneration. By giving practical instruction in Fishery at the principal Fishery-Schools, this official is, for the time being, to amend the defects of the present system of training. 27- Fishing with the so-called "ankerkuil" (Zuiderzee). HOSPITAL AND CHURCH BOAT. As a result of private initiative, and with an annual State endowment of about fi. 10,000, the Hospital and Church Boat "de Hoop" was fitted out, and siüce 1899 has been rendering service to fishermen of all nationalities. From June until the herring-fishing is over, this vessel cruises in the North Sea, in order to provide the crews of the fishing-fleet with medical and religious assistance. II. COASTAL-FISHING. As distinct from sea-fishing, coastal-fishing is mainly a "retail trade", except in regard to oyster culture and part of the mussel-fishing. The Act of 1908 regulated it apart from sea-fishing. For sea-fishing as well as for coastal-fishing the boats have to be registered and need a consent. (In 1913 there were 4,752 vessels registered and 8,849 consents were granted). The regions for coastal-fishing comprise the Dollard, the Wadden, Lauwerzee, Zuyder Zee, the Zeeland and South-Holland streams, and the territorial waters, so that in some places sea-fishing is practised along with coast-fishing. With the exception of the territorial waters, which on the whole are of a purely North Sea nature, all the said regions show more or less similar or equivalent biological properties, and the fisheries are of the same nature. The coastal-fishing comprises the fishing of: o. mollusca, (oysters, mussels). b. crustacea (lobsters, shrimps). c. divers kinds of fishes. Though of less importance than sea-fishing, coastalfishing yet plays a considerable part in the fishing-trade, providing a direct means of livelihood for more than 10,000 persons. In the years 1892—1897 coastal-fishing yielded an average of fl. 940,000, and from 1898 to 1903 of fl. 1,900,000 a year. And ever since the profits have been increasing; in 1912 thev amounted to fl. 3,984,783, in 1913 to fl. 5,160,096. 29 The major portion of the profit is yielded by the mollusca, in 1913 as much as 46.72 % of the sum total; next come the divers fishes grouped together, 42.32 %, then the crustacea with only 10.96,% of the sum total. 31 Volendam fishermen fishing with the2so-calledJj''wonderkuiL" a. Fishing for Mollusca, mainly Oysters and Mussels. Artificial oyster culture, which flourishes especially in Zeeland (Ierseke), dates from the end of last century. The young oysters are caught on tiles lying in the water, or in shells, and are taken to deeper water, outside the dyke. There they remain until they are full-grown; they are caught again by means of trailing-nets, and kept in the socalled "putten" (pits). Besides in Zeeland, we find oyster culture in the North, near Harlingen, in the Lauwerzee, in Texel and in Wieringen. 1913. number. profit.

M ussel-fishing is pursued on the banks in the north of the Zuyder Zee, and in Zeeland In the latter province it is of most importance. England is the principal pur«haser, whither the export is mainly carried on from Harlingen and Helder. Amount in KG.

This important factor for the Zuyder Zee fisheries will be treated separately further on. b. Fishing for Crustacea or Shell-fish, meaning here Shrimps, Lobsters and Crabs. Of these shrimpsare the most important. The fishermen of the North and South Holland sea-side towns fish in territorial waters, either in open boats, with a small shrimp-net, or on foot with a bayshaped push-net. At the mouths of the South-Holland and Zeeland streams larger vessels are used, whilst in the Zuyder Zee the fishing is done with the beam- and the ottertrawl. Also off Helder and in the Lauwerzee there is a good
