It was this aspect of the fisheries which was mostly regarded by the statesmen of those times, and for which the “political lent” and the protective legislation were designed. The causes which led to the decay in the English fisheries were no doubt various, but perhaps the chief one, and the one on which most stress was laid in the latter part of the century, was the Reformation. The very large consumption of fish due to the observance of Lent and the numerous days of fasting, or fish-days, has been referred to (see p. 58). The suppression of the monasteries (1536-1539) and the dispersal of the inmates and dependants must alone have had considerable influence, but the relaxation of ecclesiastical rule among the laity which followed was much more detrimental to the fisheries. The decay of the sea-coast towns, so frequently spoken of in the reign of Elizabeth, was mainly attributed to this cause. Another influence which operated in the same direction, most markedly towards the end of the century, was the great growth of the fisheries and commerce of the Dutch. After the assertion of their independence of Spain (1581), commonly called the “abjuration of Philip,” their fisheries developed with great rapidity. One of the first acts of the new Republic (1582) was the codification of the fishery statutes; and about this time they applied to the deep-sea herring fishery the name of Great or Grand Fishery (_Groote Visscherye_), as being “the chief industry of the country and principal gold-mine to its inhabitants,” in contrast to the real gold-mines of Spain. They furnished the greater part of Europe with cured herrings and other fish, and the fish supply of England, and more particularly of London, fell to a large extent into their hands. Their herring fishery was carried on along our east coast, and the spectacle of great fleets of foreign fishing vessels frequenting our waters, while the native fisheries were falling to decay, roused envious and jealous feelings in the breasts of patriotic Englishmen.[156]
