Swanside Beck, fisheries survey, 22nd September 1992

Swanside Beck is formed from a number of minor tributaries which rise in the Middop area to the west of Barnoldswick. The Beck is approximately 10 km long from the source of its longest tributary (SD. 850445) to the confluence with the River Ribble (SD. 769455). Swanside Beck has one major tributary, Ings Beck, which rises from a number of sources on Twiston Moor and is approximately 6km in length from the source of its longest tributary (SD. 812418) to the confluence with Swanside Beck (SD. 785453). Both Swanside and Ings Becks are important spawning and nursery areas for salmon and sea trout from the River Ribble. In recent years a perceived decline in the migratory fish population of the becks has been reported. This decline has been reported in terms of both adult returns and juvenile production and has been particularly noted in Swanside Beck. The aim of this survey was to assess the likely benefits to Fisheries and Conservation interests of the adoption of a set aside policy for agricultural land adjacent to Swanside Beck. The survey also formed part of an on-going Fisheries study of factors limiting juvenile migratory salmonid production in Swanside Beck. This section of the report deals with the Fisheries aspects of the survey.

Electric fishing survey of the gravel addition sites on the River Wyre, Grizedale Beck and Joshua's Beck.

Although geographically the River Wyre lies between two rivers containing major migrations of adult salmon and sea trout, its rod & line fisheries have for a number of years produced exceptionally low catches. In order to determine the causes of this the Wyre Salmon and Sea trout Restoration Group (WSSRG) was conceived in 1994 as a partnership between the then National Rivers Authority (now Environment Agency), local landowners, angling clubs and interested parties. Two studies of 1994 and 1995 stated that there is a shortage of useable spawning gravels on the river. This is compounded by Abbeystead Reservoir acting as a gravel trap, the siltation of gravels on several side becks and problems with access to available gravels by returning adults. There was also perceived to be a need for accurate fishery data from the river encompassing redd counts, catch data and surveys of fry populations. The 1995 report suggested a number of management proposals which might be adopted in order to improve and create available spawning habitat for migratory salmonids. Funding was made available to create three spawning gravels on each of two side becks (Grizedale Beck and Joshua's Beck) and the addition of gravels to a site oh the main river below Abbeystead Reservoir. Modifications were also made to the fish pass at Abbeystead to allow easier passage of fish. These improvements were made in the autumn of 1995. Salmonid spawning redd counting was undertaken on the whole Wyre catchment in 1995/1996 and specific surveys by electric fishing on the gravel enhancement sites in the summer of 1996. This report details the current state of the improvement works that were undertaken and presents the results of electric fishing surveys in September 1996. A number of lessons have been learnt which will be of great benefit to the Fisheries Function in other parts of the Wyre catchment and the Central Area in general.

Electrofishing, survey of Skirden and Swanside Beck August/September 1987.

As a follow up survey, the report assesses Skirden and Swanside Beck (North West England) in order to determine: 1. The status of these systems as salmonid nursery streams. 2. The success of planting with salmon fry and parr, carried our earlier in the year. The report gives methods, results, a summary and the author's recommendations.

A report on the strategic stock assessment survey of the Colton Beck catchment 1994 with particular reference to salmonids

This is the report on the strategic stock assessment survey of the Colton Beck catchment in 1994 with particular reference to salmonids in Colton Beck, River Ea, River Gilpin and Rusland Pool. This report forms one part of the third year of a triennial survey programme for the South West Cumbria and South Cumbria catchments. It was produced by the National Rivers Authority in 1994. Colton Beck had excellent densities of sea trout (Salmo trutta) and a small population of salmon (Salmo salar) in its lowest reaches. The total productivity was very good throughout the catchment. Stocking of sea trout fry in 1993 has enhanced the population with survivors through to parr probably adding to the scoring of double class A at two sites in the survey in 1994. Stocking was not undertaken in 1994, but the population appears to be maintaining itself at a very high level.

Report of 1996 survey of Trout Beck with particular reference to spawning gravel quality and invertebrates as a food source for salmonids

This is the Report of 1996 survey of Trout Beck with particular reference to spawning gravel quality and invertebrates as a food source for salmonids produced by the Environment Agency North West. Whilst the main River Derwent is quite a high profile salmon fishery, Trout Beck is not a significant fishery in its own right, but serves to maintain the genetic integrity of the wild populations of trout and salmon in the catchment by providing a unique habitat. This survey addressed the invertebrate food availability, and additionally looked at the substrate to try to determine whether the bed type might actually be unsuitable for spawning, especially in view of the previously mentioned silt inputs.

Report on fisheries invertebrate survey of the Groove Beck,Thornsgill Beck,Troutbeck system

This is the Report on fisheries invertebrate survey of the Groove Beck, Thornsgill Beck and Troutbeck system produced by the Environment Agency North West in 1997. In 1996 the National Rivers Authority (NRA) report on the 1992 strategic stock assessment for the Upper Derwent catchment Jane Atkins recommended that should subsequent electrofishing show continued low densities, a survey of the invertebrate fauna should be undertaken to assess the food availability for salmonids, in order that lack of food could be ruled out as a contributory factor in their poor breeding success. Additionally the survey looked at the substrate to try to determine whether the bed type might actually be unsuitable for spawning, especially in view of the previously mentioned silt inputs.

Maryland commercial fisheries statistics, 1944-1945

This report presents a statistical analyses of the "fin" fisheries, as distinguished from the crab and oyster fisheries of Maryland, for 1944 and 1945. Comparative data on the catch by species, by area, and by gear, based principally on daily reports from the fishermen, are available for the first time as a result of a comprehensive statistical survey made by the Department of Research and Eduction to determine the results of the new management plan for the fisheries, referred to as the Maryland Management Plan. With the initiation in 1941 of a new system of fishery management in the State, a conservation plan based on the principle of stabilized fishing effort, it became obvious that a more accurate catch record system was needed for the proper administration of the program. The Management Plan stabilized the number of licensed fishermen at the 1939-1940 level, and provided for controlled expansion of the fishery to take place only when and where the industry warranted it as a result of increased fish populations. The text of the Plan may be found in Article 39, Section 60, Annotated Code of Maryland, 1943 Supplement. Publications 1, 2, 5, and 6 of the Educational Series of the Department of Research and Education explain the operating principles and the application of same to two important Maryland species, the shad and the rock or striped bass. Ocean fishery records only cover monthly gross landings.

Temas de Ciencias Naturales.

El 29 de abril del año próximo pasado se cumplieron veinte años del fallecimiento de Raúl Adolfo Ringuelet, quién fuera uno de los científicos más destacados que han dado las ciencias naturales de la Argentina. Salvo contadas excepciones, no hubo recordatorios sobre este acontecimiento, pero el Dr. Ringuelet es uno de los casos que no necesita de la magnanimidad y el tiempo de los mortales para tenerlo presente, ya que la vigencia y el peso de su obra, hacen cumplir con aquello de que “mientras el recuerdo permanece, la muerte no existe”. El Programa para el Estudio y Uso Sustentable de la Biota Austral (ProBiota) quiere recordarlo reproduciendo la publicación de una serie de conferencias dictadas en su juventud, durante 1943 y 1944, en LS 11 Radio Provincia de Buenos Aires y que fueron publicadas en 1946 bajo el título de “Temas de Ciencias Naturales”. En ese año, Raúl A. Ringuelet contaba con treinta dos años y el mundo se encontraba en su mayor parte lacerado y bajo ruinas por la conducta recurrente de la “especie hipócrita” que, en nombre de las ideologías y la paz universal, había concretado la matanza de varios millones de personas. En nuestro país se asistía al nacimiento de un nuevo movimiento histórico y el comienzo de profundos desencuentros en nuestra sociedad, los cuales, lamentablemente, aún no han terminado. En esta década la ciencia argentina sería destacada con el Premio Nóbel a través del Dr. Bernardo Houssay y en las ciencias naturales se habían publicado, entre otras obras, los rasgos principales de la Fitogeografía argentina de J. Frenguelli, la Zoogeografía de Cabrera y Yepes, la última entrega del catalógo sistemático de las aves de Argentina de Steullet y Deautier, y el estudio de la Selva Marginal de Punta Lara de A. L. Cabrera (hijo) y G. Dawson. La lectura de estas conferencias, un total de diez, nos muestra, ya entonces, el espíritu rico, inquieto y polifacético de Raúl A. Ringuelet, el cuál lo distinguiría pocos años después. En algunas de ellas realiza la reseña de la vida y obra de diferentes científicos y naturalistas de nuestro país; en las restantes, expresa ingeniosamente conceptos precursores sobre biodiversidad, conservación y manejo de los recursos naturales y su transferencia a los diferentes niveles de la sociedad. Finalmente, desde ProBiota consideramos que la trascripción de este tipo de documentos constituye un aporte para aquellos interesados en la historia de las ciencias naturales y, asimismo, una contribución para que nuestras jóvenes generaciones de biólogos y naturalistas posean una noción más clara de quienes marcaron rumbos e hicieron escuela en nuestra disciplina con un genuino sentido nacional.
