32 OKHAMAITDAL MARINE ZOOLOGY REPORT 



Section II. — Recommendations eequieing Trained Supervision. 



A. — Chank Culture. If this be resolved upon I recommeud : — 



{a) That a number of chank egg capsules be obtained, say by reward offered, 

 and placed in a suitable pound or enclosure, where, after hatching, the 

 young shall be safeguarded for some weeks till, being of a size better fitted 

 to enable them to cope with enemies, they be distributed to the principal 

 chank grounds. 



{b) Later on, when further experience be gained, numbers of sexually mature 

 adults may be impounded with a view to obtain egg capsules more readily, 

 and in greater numbers. 



B. — Culture of Edible Oysters. 



When an officer with sufficient training be available, I suggest that he should 

 be instructed : — 



(a) To ascertain the limits of the spatting season, and to determine the factor 

 which supplies the stimulus necessary to induce emission of the sexual 

 products ; whether this be increase of temperature, as in Europe, or 

 decreased density of the water consequent upon monsoon floods, as is the 

 factor in Southern India. 



(6) To set spat collectors of different forms in different places in Aramra Creek 

 at the beginning of the spawning season, and to note the comparative 

 results with exactitude. 



(c) When the young oysters thus obtained be of sufficient size, to detach them 



and " lay " them on prepared bottom on the banks of the creek. 



(d) To vary the experiments as greatly as possible with a view to ascertain what 



procedure gives the best results locally. 



Section III. — Sea-fishing and Fish-curing. 



While restrictions of area preclude any great development in the case of all the 

 preceding marine products, sea-fishing is wholly without such hampering bonds ; on 

 the other hand, as no nucleus of such an indu.stry exists on or around which to build 

 and develop, a great amount of preliminary investigation and effort is requisite before 

 practical work on a commercial scale can be attempted. The first requisite is to obtain 

 a well-trained and level-headed expert having practical knoivledge of the more 

 important methods of fishing as practised in other countries. To him should be 

 entrusted the task of ascertaining : — 



(a) All that is worthy of note in the collecting, curing, and distributing of fish 

 on the neighbouring coast of Sind.
