Book excerpt: Excerpt from Report to the Government of Ceylon on the Pearl Oyster Fisheries of the Gulf of Manaar, Vol. 4: With Supplementary Reports Upon the Marine Biology of Ceylon, by Other Naturalists Another factor which may have an important bearing upon the future history Of the Ceylon Pearl Fisheries is the proposal that the pearl banks should be leased for a period of years to a Syndicate, which will be bound by the terms of the lease to expend a considerable sum annually in the cultivation and exploitation of the fishing grounds. It seems probable at the time of issuing this volume that the next Ceylon Pearl Fishery will be held under the auspices of the Syndicate.

This book was released on 2017-02-03 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Report to the Government of Ceylon on the Pearl Oyster Fisheries of the Gulf of Manaar, 1903, Vol. 1: With Supplementary Reports Upon the Marine Biology of Ceylon, by Other Naturalists AN introduction explaining briefly the past history Of the Pearl Banks in the Gulf of Manaar and the circumstances which led to my Ceylon Expedition, and the subsequent work to which it gave rise, is followed by a section, entitled narrative, which deals with the course Of the investigations undertaken by Mr. Hornell and myself, given in chronological order. The Observing stations where the fauna was investigated around the Coast of Ceylon are described in detail in the Narrative but those other investigations - such the anatomy Of the Pearl Oyster, a description Of its parasitic worms, and an account Of its pearl-formation - which will be dealt with separately in special articles later on, are not treated fully in this section. After the Narrative comes a Description Of the physical condition of the pearl-oyster banks or paars of the Gulf of Manaar, followed by their classification from the fisheries point of View, and by a short discussion as to the causes of certain paars being unreliable, and of the serious mortality of the oysters. Then comes a section dealing with the Observations and Experiments made by Mr. Hornell and myself on the life-history and habits of the pearl oyster, which form the basis of some of our recommendations as to the cultivation Of the oyster banks. This general part is then followed by the Supplementary or Special Reports, which various scientific friends have kindly undertaken to write upon their special groups or subjects. I feel that these articles by experts add very greatly to the completeness and value Of this Report, which without them could only have given a very imperfect account Of the fauna and flora of the Gulf of Manaar and Of the other natural conditions of existence surrounding and influencing the pearl oyster on the various paars. Of these special Reports, seven are published in the present Part I. The first of these is on the Geology 01 the Sea-bottom, by Mr. Joseph lomas, it deals with the very fundamental question of what the paar is, how the hard, cemented material usually known (and marked on the charts) as rock, which by its presence enables the pearl oysters to live there, comes to be formed.

This book was released on 2015-08-06 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Report to the Government of Ceylon on the Pearl Oyster Fisheries of the Gulf of Manaar, Vol. 2 Part I. of this work was issued in November, 1903, and contained the following sections: - (a) In the Pearl Oyster Report proper: (1)the Introduction; (2)the Narrative; (3)the Description of the Pearl Banks;(4) Observations on the Sea; and(5) Observations and Experiments on the Life-History and Habits of the Pearl Oyster; (b) In the series of Supplementary Reports: I, the Sea-bottoms; II, the Marine Algse; III, the Gephyrea; IV., the Polyplacophora; V., the Holothurioidra; VI., the Cephalochorda; and VII., the Copepoda. Along with that volume, I submitted to the Government of Ceylon a type-written section dealing with practical recommendations as to the conduct of the. inspections and fisheries, and as to the best means of conserving and exploiting the pearl banks. These recommendations, when revised and added to if necessary, as the result of further observation and experiments, will be given as the final section of the last volume of this Report. In January, 1904, Mr. James Hornell was appointed Marine Biologist to the Ceylon Government, and soon after the further duties of Inspector of the Pearl Banks were added to his office. Facilities have now been given to him for carrying out the work, both experimental and executive, recommended in this Report, and he is at the present time engaged in testing the effects, under different conditions, of lifting oysters (both young and old) in bulk, by means of dredges. The transplantation of young oysters will also engage his attention, and the first results of his labours will probably be available for use before this Report is concluded. In the present Part II., after a discussion of the past history of the principal "paars," Mr. Hornell and I give our account of the Anatomy of the Pearl Oyster, and that is followed by a notable section on the Parasites, contributed by Mr. Shipley and Mr. Hornell.

Book excerpt: Excerpt from Report to the Government of Ceylon on the Pearl Oyster Fisheries of the Gulf of Manaar, Vol. 5: With Supplementary Reports Upon the Marine Biology of Ceylon by Other Naturalists But this must be the final volume, and I wish now, in bringing the work to an end, to make use of this opportunity mainly for the purpose (1) of reiterating my thanks to many friends who have kindly helped me, (2) Of correcting such errors and omissions* in the former volumes as have come to my notice, and (3) of saying my final word as to the present position and future prospects of the pearl fisheries. I have reluctantly come to the conclusion that an index to the five volumes is impracticable. If it contained all Specific names it would be largely an unjustifiable repetition Of our lists, and every Zoologist who consults the work will be readily able to find any desired species from the classifications given in the reports. It may, however, be some aid to the reader if I give here a scheme indicating in which Part each section of the subject and each special report will be found. The sections of the pearl-oyster report proper are arranged in chronological order, as that corresponds with the natural development of the subject, from preliminaries to final conclusions, and the special, or supplementary, reports are placed in zoological order from the lowest groups to the highest, so that the position of each in the volumes can be ascertained from this list at a glance.

Locality: --Periya Paar, Gulf of Manaar, 9 fathoms. Halisceptrum gustavianum (herklots). This species is represented by one complete specimen. Of the 23 millims. forming the stalk the lower 11 millims. consist of nothing but the axis which tapers to a point. At the upper end of the 11 millims. the axis has a diameter of 1 '3 millims. and is cylindrical in shape. In the rachis the stalk becomes grooved and approximates to a quadrangular shape. A groove is distinctly seen in the prorachidial face of the rachis, but this fades away and disappears in the lower part of the rachis. The pinnules show a large number of polyps which appear to be arranged in a number of rows. In the immature pinnules the polyps are in a single row, but they soon begin to alternate, and in the mature pinnules they seem to be in six rows. The number of mature pinnules is very small compared with that of the immature, the numbers being 16 pairs to 40 pairs. Pinnules: Breadth, 2'5 millims.; height, 2'5 millims. Distance between origins of pinnules, 4 millims. Length of whole colony, 86 millims. Locality: Station LII., Gulf of Manaar, 3 to 6 fathoms. Pteroeides lacazei, var. spinosum, Kolliker. This species is represented by a fragment only of the upper portion of the rachis, measuring about 36 millims. in length, with 15 pinnules on one side, 16 on the other. The principal measurements are as follows: --'Width of rachis, 48 millims.; breadth of pinnule, 20 millims.; height of pinnule, 12 millims.; number of main rays, 12. There is a single row of zooids running down the centre of the meta-rachidial surface. The wart-like termination of the rachis is almost completely hidden between the two uppermost pinnules. The rachis seems to have been swollen towards the tip and the.
