River Lune salmon action plan March 1997. Draft Copy.

The River Lune was at one time one of the best salmon fisheries in England and Wales with very high catches to both rods and netsmen. During the 1960's, the stock was decimated by the disease Ulcerative Dermal Necrosis which caused a dramatic reduction in catches. Catches have not recovered to pre-disease levels. The target egg deposition rate for the River Lune system which should produce the maximum number of surplus fish returning to the system has been determined at 13.8 million eggs. This will require 4,779 adult salmon to survive to successfully spawn. Under current rates of exploitation, the target egg deposition will occur at a declared rod catch of 1,974 salmon and a net catch of 2,627 salmon. Two automatic fish counters are in operation on the river system. Data from these suggest that, within the measures of compliance, the river has met it's target egg deposition for the last 3 years.

River Lune juvenile fish stock assessment 1997 with particular reference to salmonids

This report presents data from the juvenile salmonid fish stock assessment which is part of the routine Environment Agency riverine monitoring programme. A total of 110 sites was electrofished throughout the Lune catchment between 15th July 1997 and 14th October 1997. These sites included 84 that had been previously sampled in the last comprehensive survey of the catchment, in 1991. The aim of this survey was to assess the distribution and abundance of juvenile salmon and trout in the River Lune catchment and to compare results with those of previous surveys.

Environmental effects of drought and abstractions of River Wharfe fisheries, summer 1997

This investigation was carried out to provide information on fish stocks and angling activity during 1997 in relation to the drought and, in particular, flows as influenced by Time Limited Licences. These abstractions will be for review in 1999. This report extends and updates the data presented for 1996. Fish population surveys (including eels) were undertaken on the main river and selected tributaries. Angler caught brown trout were examined, angler catch data have been reviewed, and observations by Environment Agency fisheries staff collated. It appeared that in River Wharfe both the fish populations and individual fish appeared to be in good condition and limited changes had occurred since the 1996 survey.

1997 fisheries statistics, Lake Kariba - Zimbabwe shore

The report provides catch records for the kapenta (Limnothrissa miodon) and inshore fisheries in the Zimbabwean waters of Lake Kariba for the year 1997. Kapenta usually constitute about 94% of the total catch from Lake Kariba; for statistical purposes catches are recorded for the 5 hydrological basins - Mlibizi, Binga, Sengwa, Bumi and Kariba. The kapenta, which occupy the open pelagic waters of the lake, represent a unit stock which is harvested by both Zimbabwe and Zambia; the artisanal fishery exploits inshore species which generally occupy water less than 10m deep along the shoreline. The Zambian and Zimbabwean inshore fisheries may therefore be considered to be exploiting 2 separate stocks. The main species in the inshore fishery are Oreochromis mortimeri, Sargochromis codringtonii, Tilapia rendalli, Labeo altivelis, Hydrocynus vittatus, Mormyrus longirostris, M.anguilloides and Clarias gariepinus.

Environmental effects of drought and abstractions of River Ouse fisheries, summer 1997

This survey was the second year of a three year study to examine fish populations in relation to low flows, drought and abstraction in the River Ouse. To fully evaluate the possible effects on fisheries the study set out to encompass fish population surveys from fry to adult stock, analysis of angler catch data, reports from anglers and river reports from Environment Agency Fisheries staff.

River Ribble sheep dip incident September 1997. Electric-fishing survey report

This report summarises the findings of a series of electric-fishing surveys carried out at four sites on the River Ribble from September 1997 to September 1998. The aims of these surveys were to assess the impact on juvenile salmonids of a pollution incident involving Synthetic Pyrethrin (SP) that occurred near High Birkwith I (SD 802 767) in September 1997.One of these sites was 2.65km upstream of the pollution whilst the remaining three were at varying distances downstream. Data was collected during surveys of the River Ribble in 1992, 97 and 98. The 1997 and 1998 surveys were carried out specifically to monitor for any possible effects of the SP discharge. Data are shown as grades derived from the National Fisheries Classification scheme (NFC). Results are given for the four salmonid life stages; 0+ trout, >0+ trout, 0+ salmon, >0+ salmon and also Total Salmonids.

Effects of the 1997-1998 El Niño on population size and diet of the Galápagos sea lion (Zalophus wollebaeki)

The multi-annual climatic event, El Niño Southern Oscillation (ENSO) is an important factor in the population dynamics of coastal marine species in the Galápagos. The Galápagos sea lion, Zalophus wollebaeki, suffered an apparent population decline of about 50%, considering both mortality and movements away from study sites during the 1997-98 El Niño. This change was in part due to changes in the availability of sardines of the Family Clupeidae, its main prey. These declines resulted partly from elevated mortality (35%) in sea lion colonies, particularly among pups, juveniles (< 1 year old), and dominant males and as a result of movements of adults elsewhere (15%), presumably where there were alternative prey and better environmental conditions.

Fragmento de un epítome del «Liber Glossarum» en un manuscrito de en torno al año 1000

[EN] This article consists of a study (provenance, date of the manuscript, sources of the glossary, etc.) and an edition of the fragment of an epitome of the «Liber Glossarum» which is contained in a ms. about the year 1000 A.D. From the "Spanish symptoms" which one can track in the present copy, the ms. El Escorial L.I.15, from the 16th-17th century, the author infers that his model, now perished, was written in Spain and in wisigothic script about the year 1000. On the other side, on the basis of the copy the author reconstructs the primitive glossary text of the 10th-11th century model in a critical edition accompanied by a critical apparat and sources.

Results of bottom trawl surveys carried out in Vietnamese waters (20-200 m) in 1996-1997

Bottom trawl surveys were conducted in the southwest monsoon season in 1996 (survey 1) and in the northeast monsoon season in 1996-97 (survey 2) throughout Vietnamese waters. The surveys mainly covered the depth zone 50-200 m but in the northeast monsoon season the depth zone 20-50 m was included in the northern and southern areas. Overall, 273 trawl hauls were conducted. The total biomass for Vietnamese waters in the depth zone 20-200 m was estimated at 700 000 t . Biomass estimates are given for the most abundant species. A relatively higher mean catch-per-unit effort (CPUE) was obtained from survey 2 than from survey 1 and in partcular at depth ranges 50-100 and 100-200 m in south Vietnam. Overall, the dominant families were Monacanthidae (34%), Carangidae (15%), Trichiuridae (9%) and Synodontidae (6%).

A concessão de patentes de medicamentos fitoterápicos no Brasil: uma análise do período 1997-2004

Este trabalho aborda o problema do consumo desenfreado de produtos naturais no Brasil, especificamente de medicamentos fitoterápicos, com suas consequências, discutindo à luz do Direito de Propriedade Industrial e o Direito Sanitário. Procura relacionar o papel e a responsabilidade do INPI e a ANVISA, órgãos diretamente envolvidos na legislação mencionada, para a melhoria da qualidade de produtos fitoterápicos registrados e lançados no mercado brasileiro. Mostra a necessidade de uma reavaliação dos critérios de concessão de patentes para a área analisada por parte do INPI, bem como uma maior aproximação da ANVISA junto à este órgão, de modo que harmonizem estratégias para que a população tenha acesso a medicamentos fitoterápicos seguros e eficazes. Explicita as estratégias d indústria nacional do setor em alavancar suas vendas no mercado, através de projetos de lei que não traduzem com a realidade preconizada pela OMS, para o uso da Medicina Tradicional/Complementar, contrariando a legislação brasileira para o possível registro dos produtos patenteados. Conclui-se que interesses econômicos, ligados à acirrada concorrência no mercado de fitoterápicos e suplementos nutricionais, induzem à concessão de patentes para tais produtos, em detrimento das diretrizes existentes na Lei de Propriedade Industrial brasileira, em critérios de avaliação.
