The fisheries of Lake Wamala: a report on the fisheries resources surveys conducted during 1975/78 and 1988/92

Lake wamala was opened to commercial fishing in 1960. Interviews with the local fishermen during 1975/78 (Okaronon 1975, 1976, 1977, 1989) revealed that fishing for subsistence had been going on long before stocking was done. The subsistence fishing was conducted along rivers and at river mouths using basket traps (mainly made of papyrus stems), weirs and hooks and that the fish species caught were predominantly clarias (mudfish/male) and protopterus Lungfish/Mamba). These interviews did not, however, reveal the presence of tilapiine species in Lake wamala prior to stocking. These interviews did not however reveal the presence of tillapine species in lake wamala prior to stocking. Following the opening of the lake to commercial fishing in 1960, Lake Wamala provided a very profitable commercial fishery throughout the 1960s. However, during the early 1970s the fishermen started complaining of continued decline in catch rates from about 8 kg (15 fish) of O. niloticus per net per night if in 1966 to less than 1 kg per net per night by 1975.

Experimental fisheries resource survey of Lake Wamala: Annual report 1975

During 1975, two experimental fisheries resource surveys were conducted on lake wamala from 14th to 20th May and 10th to 16th July. The purpose of the experimental fishing on this lake was to provide information required to genrate enough scientific guidelines and advice for rational exploitation, management, development and utilization of the fishery resources in the lake.

Lakes Wamala and Kijanebalola: evaluation of the fisheries resources during July 1975

This report presents the results of the second (in 1975) fisheries resource survey for Lake Wamala conducted from 10th to 16th July 1975. The first similar survey covered the period 14th to 20th May 1975. The areas sampled consisted of the river-month areas, the papyrus-fringed inshore waters and the open dee offshore waters. In an effort to find the possible major causes of the decline in catch and seasonal disappearance of fish-hence a solution to the problem(s)-a second fisheries resource survey using multifilament nylon gillnets was conducted on Lake Kijanebalola during the period 17th to 21st July 1975. The first survey was similar and covered the period 21st to 27th May 1975.

武汉东湖浮游植物的演变(1956-1975年)和富营养化问题

本文根据1956—1957、1962—1963和1973—1975年在湖北省武汉市东湖进行的三次调查资料,总结了过去二十年内在东湖两个代表性采样站上浮游植物群落生态学的主要变化(包括数量、种类组成、优势种类、多样性指数和初级生产力)。年平均总数在二十年内由每毫升几百个增为几千个。由甲藻和硅藻占优势逐步转变为以绿藻和蓝藻占优势,蓝藻中的大型种类明显增加。年数量变动曲线原来呈春季和秋季两个高峰,但60年代后,已变为夏、秋季的一个蓝藻高峰,而且数量大,延续时间长。浮游植物的年初级生产量和日最高初级生产量也有明显

Anglo-Irish relations in the framework of the EEC and Northern Ireland, 1969-1975

This thesis will analyse Anglo-Irish relations between 1969 and 1975, when two topics dominated the relationship: Northern Ireland and the entry of Britain and Ireland into the European Economic Community (hereafter EEC). In 1969 entry to the EEC was still only a possibility and awaited political developments, while the Northern Ireland problem had yet to escalate. 1975 on the other hand confirmed that Ireland would remain in the EEC even if Britain left while Direct Rule for Northern Ireland was confirmed as the British policy for the foreseeable future. These dates are significant because they encompass firstly pre and post entry to the EEC and how this transformed Anglo-Irish relations. Secondly they contain the commencement and then deterioration of the Northern Ireland problem and the attempts to resolve it that finally led to direct rule by Westminster. The study will examine the fluctuating nature of the relationship between Britain and Ireland. Special regard will be devoted to the demands of internal British politics and how such demands affected the relationship. Overall, the study will demonstrate how the bilateral relationship evolved under the pressure of events in Northern Ireland and adapted to the multilateral context of the EEC. It will compare the dynamics of the states’ interactions in two extremely different areas. The thesis will demonstrate how entry to the EEC transformed the unequal Anglo-Irish economic relationship and created one of partners within the EEC. It will also analyse how the developing Northern Ireland problem caused changes to British policy. In particular, it will examine how the British Government came to recognise the beneficial role that the Republic of Ireland might play in resolving the Troubles in Northern Ireland.

Selected Solo Music for Saxophone by United States Composers: 1975-2005

This dissertation project identifies important works for solo saxophone by United States composers between 1975 and 2005. The quality, variety, expressiveness, and difficulty of the solo saxophone repertoire during these thirty years is remarkable and remedies, to some extent, the fact that the saxophone had been a largely neglected instrument in the realm of classical music. In twentieth-century music, including Jazz, the saxophone developed, nevertheless, a unique and significant voice as is evident in the saxophone repertoire that expands immensely in many instrumental settings, including the orchestra, solo works, and a wide variety of chamber ensembles. Historically, the saxophone in the United States first found its niche in Vaudeville, military bands, and jazz ensembles, while in Europe composers such as Debussy, D'Indy, Schmitt, Ibert, Glazounov, Heiden, and Desenclos recognized the potential of the instrument and wrote for it. The saxophone is well suited to the intimacy and unique timbral explorations of the solo literature, but only by the middle twentieth century did the repertoire allow the instrument to flourish into a virtuosic and expressive voice presented by successive generations of performers – Marcel Mule, Sigurd Rascher, Cecil Leeson, Jean-Marie Londeix, Fred Hemke, Eugene Rousseau, and Donald Sinta. The very high artistic level of theses soloists was inspiring and dozens of new compositions were commissioned. Through the 1960’s American composers such as Paul Creston, Leslie Bassett, Henry Cowell, Alec Wilder, and others produced eminent works for the saxophone, to be followed by an enormous output of quality compositions between 1975 and 2005. The works chosen for performance were selected from thousands of compositions between 1975 and 2005 researched for this project. The three recital dates were: April 6, 2005, in Gildenhorn Recital Hall, December 4, 2005, in Ulrich Recital Hall, and April 15, 2006, in Gildenhorn Recital Hall. Recordings of these recitals may be obtained in person or online from the Michelle Smith Performing Arts Library of the University of Maryland, College Park.
