This report continues to cover the period of the financial year. Although, as before, for the sake of continuity and accuracy many of the statistics refer to the calendar year. The year has been notable in particular for the launching of extensive research projects on wild-life conservation problems, and much progress has already been made. This has been rendered possible by the greatly appreciated help and interest of the Fulbright Commission, who arranged for three experienced American wild-life scientists to work on these problems in Uganda. The latter have been working in conjunction with The Game and Fisheries Department's Biologist, as a team under the general Direction of the recently created Fauna Research Committee.

This paper describes the effect of the state of the inlet boundary layer (laminar or turbulent) on the structure of the endwall flow on two different profiles of low-pressure (LP) turbine blades (solid thin and hollow thick). At present the state of the endwall boundary layer at the inlet of a real LP turbine is not known. The intention of this paper is to show that, for different designs of LP turbine, the state of the inlet boundary layer affects the performance of the blade in very different ways. The testing was completed at low speed in a linear cascade using area traversing, flow visualization and static pressure measurements. The paper shows that, for a laminar inlet boundary layer, the two profiles have a similar loss distribution and structure of endwall flow. However, for a turbulent inlet boundary layer the two profiles are shown to differ significantly in both the total loss and endwall flow structure. The pressure side separation bubble on the solid thin profile is shown to interact with the passage vortex, causing a higher endwall loss than that measured on the hollow thick profile.

In the present study the specimens collected by the Austrian-Ceylones hydrobiological mission 1970 are described. The freshwater gastropods in this study were collected from 100 different localities, mostly running waters, but some were also collected from stagnant waters like pools, irrigated paddy fields, swamps and water reservoirs (tanks). Listed from these localities are 31 species (and subspecies) 28 species are Streptoneura (=Prosobranchia), 3 species are Euthyneura-Pulmonata Basommatophora.

The experience of the Government in the recovery of loans for 28 foot mechanized vessels has been unsatisfactory. The author examines the various aspects which have contributed to this situation, and considers arrangements for financing purchase of such vessels. The risks associated with the investment in 38 foot vessels are high, and it seems that the reluctance of private investors to make the required contribution from personal funds is a result of fear of the unknown. Current incentives provided by the Government to the private sector for the purchase of 38 foot vessels are considered to be adequate.

This report concerns the aquatic and semiaquatic Hemiptera collected in Sri Lanka by Prof. Starmühlner and Prof. Costa during November and December 1970. A surprising number of new species have been found in the Starmühlner-Costa material, even in groups for which comprehensive revisions exist. Seven new species are described here.

This Annual report sets out clearly the various activities undertaken by the ministry in the field of fisheries for the period 1971. It has highlighted some commendable achievements for fisheries to claim its place among the rapidly expanding rural industries in this country. Fish production now at 162,000 metric tons per annum worth over 130 million shillings at the lakeshore, is not only a source of food but also a source of employment. It is believed that the fishing industry is at the moment employing more than 35,000 people in the various aspects of the industry, for example, fishing, fish processing, fish marketing and manufacture of fishing equipment. It is, therefore, greatly contributing not only to our nutrition but also to the economic development.
