From 1855 to 1863, and also from 1874 to 1881, the returns were only ordinary, the highest being £51,017 in 1863, and £59,868 in 1881,—the best year since 1814; and during these two periods fishing was entirely omitted in nearly one half the seasons. There were five lean years from 1882 to 1886, and the 1887 fishery was only fair, with a yield of £39,609. But the returns for 1888 were large, amounting to £80,424; and those for 1891 were even greater, being £96,370, representing a yield of 44,311,441 oysters. No oysters were caught from 1892 to 1902, inclusive. In 1903, the fishery was profitable, yielding 41,180,137 oysters, and the share of the government amounted to £55,303; and in 1904 the yield was almost the same, being 41,039,085 oysters and a revenue of £71,050 to the government. In 1905 occurred the greatest fishery in the modern history of Ceylon. The season extended from February 20 until April 21, giving forty-seven working days, exclusive of Sundays and five days of bad weather, the longest period in over half a century.[131] The boats employed numbered 318, with 4991 divers and 4894 attendant _manduks_. The yield of oysters exceeded all records, amounting to 81,580,716 in number, or nearly twice as many as in any previous year within the period of British occupation. The prices at which these sold ranged from Rs.24 to Rs.124 per thousand, with an average of Rs.48.89 for the entire season. The government received Rs.2,510,727 as its share of the revenue, which was twice as much as in any previous year since the British have been in control, and doubtless the largest received by any government in the history of the industry. The oysters falling to the share of the divers must have sold for at least Rs.1,255,363 (since 1881 the divers have received one third of the catch as their compensation, instead of one fourth). The profits of the merchants, who purchased and opened the government oysters as well as those of the divers, doubtless amounted to fully as much, making a total of Rs.5,021,453, or nearly $2,000,000 as a low estimate of the local value of the pearls secured at Ceylon in 1905.
