This is the South Area still waters 1995 November surveys from the National Rivers Authority, 1996. The report focuses on the surveys of ten Cheshire Meres (Betley, Budworth, Combermere, Hatchmere, Oak mere, Pick mere, Redes, Rostherne, Tabley, and Tatton) previously surveyed in November 1994 and May 1995. Eight others (Chapel Mere, Little Mere, Marbury Mere, Mere Mere, Oss Mere, Petty Pool, Quoisley Big Mere and Tabley Moat) were surveyed for the first time. Two other lakes, Carr Mill Dam and Pennington Flash, were surveyed. Neither of these are considered to be part of the Cheshire meres group of lakes but are of a Regional interest. This report discusses the results of the November 1995 survey before making a comparison between these and the November 1994 survey results. The section on results contains information about water column profile; nutrients (chlorophyll a; Phaeophytin; Nitrate and Nitrite; Ammonia; ortho-Phosphate; Silicate; and total Phosphorus.

This is the River Gowy rapid corridor survey July 1995: Ecology South Mersey report produced by the National Rivers Authority North West Region in 1995. This report looks at the survey carried out by the South Mersey Ecology Team prior to routine deweeding operations on the main River Gowy at the end of July, 1995. The survey covered Flood Defence Stretch References RGOW03 to RGOW16. These stretches were further divided into a series of 43 stretches, each one being approximately 500m in length for ease o f mapping by Ecology. Recommendations for each length have been cross-referenced with the Bill of Quantities where possible, e.g. retention o f margins. In Flood Defence stretch RGOW03, the South West Winter Wetland forms an important habitat for birds. In stretches RGOW04 to RGOW05, the Gowy Meadows and Ditches have been designated a Grade A, Site of Biological Importance, by Cheshire County Council due to the nature of the acidic grassland and diverse ditches. In stretches RGOWIO to RGOW11 the left bank forms Hockenhull Platts, Grade A Site of Biological Importance and County Trust Reserve. In stretches RGOW15 to RGOW16, the area from Mill Farm to the Shropshire Union Canal is a Grade A Site of Biological Importance. These sites are very sensitive and detailed recommendations for working practices can be found in the relevant sections o f the survey.

This is the report on the strategic fisheries stock assessment survey of the River Winster 1995 together with a coarse fish survey in 1994 and reference to the 1995 drought, produced by the Environment Agency North West in 1996. Salmonid production within the Winster catchment was dominated by trout although good densities of salmon juveniles were found on some main river sites. Despite suffering drought conditions for much of 1995, only salmon fry production appeared to have been affected. Coarse fish populations once found in the lower reaches of the Winster appear to have declined to very low levels with no fish sampled. This may be partly due to broken tidal gates allowing saline intrusion. It seems that the lower river was suited to the development of a recreational coarse fishery, now that the gates have been repaired. This report completes the strategic stock assessment surveys planned for the period 1992-1995. It represents the last major catchment that was surveyed to determine the current status of fisheries in the South and South West Cumbria areas.

This is the Brown trout habitat assessment on the River Bela catchment produced by the Environment Agency North West in 1997. The Environment Agency (EA) and its predecessor the National Rivers Authority undertook strategic fish stock assessments in 1992 and 1995 on the River Bela catchment. These surveys found low numbers of brown trout {Salmo trutta) at some sites. Following this, habitat evaluation assessments were undertaken on the eleven poorest sites Factors probably responsible for declining trout populations on the three main tributaries of the Bela catchment include: Overgrazing by farm stock; Lack of suitable cover for parr; the absence of suitable spawning areas; existing potential of certain areas within the catchment not being utilised, due to poor dispersal. Habitat Improvement Schemes (H.I.S) are discussed and prioritised.

O trabalho a ser desenvolvido tem como objetivo compreender a relação complexa da política pública para a educação superior, entre 1995 e 2010, utilizando arcabouço teórico do neo-institucionalismo. Por meio da análise tridimensional da política (polity, politics e policy), a pesquisa procurará construir o ambiente multifacetado do processo de gestão da política pública, que teve início na constituição da agenda pública e perpassa a formulação e a implementação da política educacional nos governos dos presidentes Fernando Henrique Cardoso (1995 a 2002) e Luis Inácio Lula da Silva (2003 a 2010). O fio condutor é a dinâmica da Arena Decisória de Educação Superior, na qual a política pública gestada pelo Ministério da Educação (MEC) influenciou e foi influenciada pelo conjunto de atores governamentais e sociais. A política pública foi entendida como um conjunto sistêmico interdependente de Sete Pilares, a saber: autonomia, centralização do poder decisório, avaliação, formação de professores, flexibilização curricular, expansão e financiamento, que contribuíram para intervenção do Poder Público em prol da expansão da educação superior. Levando-se em conta as especificidades de cada momento histórico, o trabalho pretende construir um ambiente socioeconômico e as limitações fiscais, a fim de estabelecer uma análise comparativa entre as duas presidências.

Se presenta la situación actual de las lisas (Pisces, Mugilidae en Cuba, espacialmente respecto a los daños sufridos en sus pesquerías de 1971 a 1995. Se revisan las especies marinas presentes en aguas cubanas y sus características generales, así como las principales zonas, artes y épocas de pesca. Se presentan las capturas por regiones y se analizan los desembarques por categorías, de acuerdo con su composición por espec1e. Se revisa la Situación del grupo en los últimos años, cuyas capturas han disminuído a sólo un 5% del nivel más alto alcanzado, debido a los perjuicios ambientales de las lagunas y áreas costeras aledañas causadas por acciones antrópicas, que se describen, así como por disminuciones en el esfuerzo pesquero. Se presentan las relaciones entre las capturas y la capacidad de agua embalsada acumulada en el país, así como entre la talla media de las hembras de Mugil liza y el año en el periodo de 1981 a 1989 en la localidad históricamente más importante. Se analizan propuestas para incrementar la producción de los mugílidos en Cuba relacionadas con las pesquerías y la aplicación de técnicas de "Vallicultura integrada" como única vía para rehabilitar el medio ambiente lagunar con un balance adecuado de costo-rentabilidad. ABSTRACT The present status of the mullets (P1sces, Muglhdae),Cuba is rev1ewed, spec1ally in relation to their físhery between 1971 end 1995. The manne spec1es, Cuban waters, the1r general characterst1cs, as well as the main zonas, gears and flshmg Matons are shown. The captures by reg1ons and the landings by category and by specíes compositton are anatysed . The 11tuat10n ol the group in recent years is rev1ewed , in which the captures decreased to only 5% of the h1ghest leve! attamed due to envuonmental damages to coastal lagoons and nearby areas causad by human actions and by a lower flsh1ng effort. The retau onsh1ps are shown between captures and the country's cumulatíve capacitv of water dams, as well as that of the average s11e of Mugilliza tamales m the years between 1981 and 1989 ín the most historically important locat1on •. Proposals to mcrease mullet production in Cuba m relat1on to fisheries and establishment of "i ntegrated Vallicultura• as the only wav of restonng the tagoon environment with a good cost-benefi t balance are analysed.
