A survey of aquatic invertebrates of the Somerset Levels, August 13-14, 1981

Since 1975 the wildlife interest of the Somerset Levels and Moors have been assessed. Detailed information has been obtained on the conservation interest of meadows, breeding and wintering bird populations and the botany of aquatic habitats (rhynes). Little work to date has been carried out on the terrestrial and aquatic invertebrate fauna. The prime aim of this survey was to sample a wide variety of rhynes in order to obtain information on the nature and distribution of aquatic invertebrates.

Salmon action plan. River Ribble - August 2000

In February 1996 A Strategy for the Management of Salmon in England and Wales was launched by the National Rivers Authority. The strategy concentrates on four main objectives for the management of salmon fisheries in England and Wales: (i) Optimise the number of salmon returning to home water fisheries, (ii) Maintain and improve the fitness and diversity of salmon stocks, (iii) Optimise the total economic value of surplus stocks, (iv) Ensure necessary costs are met by beneficiaries. These four objectives will be addressed through local Salmon Action Plans (SAPs) which will be produced for each of the principle salmon rivers in England and Wales by the year 2001. This Salmon Action Plan for the River Ribble reviews the status of the stock and the fisheries, seeks to identify the main factors limiting performance, to draw up and cost a list of options to address these, and to consult with local interest groups.

A field guide for Agency staff operating the SIMRAD EY500 portable scientific echosounder. 2nd draft 3rd August 1999

This manual has been produced by members of the national acoustics group (NAG) and represents the first in a series of outputs designed to promote co-ordination and consistency in Agency hydroacoustic surveys. It is designed as a field guide for Agency staff operating the SIMRAD EY500 portable scientific echosounder. It should be simplistic enough for the newcomer to EY500 to be able to set up and run a mobile hydroacoustic survey with some knowledge of the supporting theory. It should act as guidance for standardisation of survey procedures providing a concise list of settings and recommendations that can be used as a quick reference guide in the field. This manual condenses 5 years of practical experience of surveying fish populations using Simrad hardware and software for surveying large rivers and still waters throughout England and Wales. This document should be used as a companion to the manufacturers instruction manual and not act as a substitute for it.

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.

Biology and assessment of the painted sweetlips (Diagramma pictum (Thunberg, 1792)) and the spangled emperor (Lethrinus nebulosus (Forsskål, 1775)) in the southern Arabian Gulf

The population biology and status of the painted sweeplips (Diagramma pictum) and spangled emperor (Lethrinus nebulosus) in the southern Arabian Gulf were established by using a combination of size-frequency, biological, and size-at-age data. Transverse sections of sagittal otoliths were characterized by alternating translucent and opaque bands that were validated as annuli. Comparisons of growth characteristics showed that there were no significant differences (P>0.05) between sexes. There were well defined peaks in the reproductive cycle, spawning occurred from April to May for both species, and the mean size at which females attained sexual maturity was 31.8 cm fork length (LF) for D. pictum and 27.6 cm (LF) for L. nebulosus. The mean sizes at first capture (21.1 cm LF for D. pictum and 26.4 cm LF for L. nebulosus) were smaller than the sizes for both at first sexual maturity and those at which yield per recruit would be maximized. The range of fishing-induced mortality rates for D. pictum (0.37−0.62/yr) was substantially greater than the target (Fopt=0.07/yr) and limit (Flimit=0.09/ yr) estimates. The range of fishing-induced mortality rates for L. nebulosus (0.15/yr to 0.57/yr) was also in excess of biological reference points (Fopt=0.10/yr and Flimit=0.13/yr). In addition to growth overfishing, the stocks were considered to be recruitment overfished because the biomass per recruit was less than 20% of the unexploited levels for both species. The results of the study are important to fisheries management authorities in the region because they indicate that both a reduction in fishing effort and mesh-size regulations are required for the demersal trap fishery.

Evidências de necessidades de autocuidado de militares com hipertensão arterial sistêmica da Marinha do Brasil: contribuição da Enfermagem

Este estudo refere-se às evidências de necessidades de autocuidado de militares com hipertensão sistêmica da Marinha do Brasil. A hipertensão arterial é uma das doenças crônicas mais frequentes, de maior prevalência no mundo e a sua evolução leva a complicações que comprometem todos os sistemas orgânicos. Neste sentido o problema apresentado é: como se caracterizam as necessidades de autocuidado de militares hipertensos da Marinha do Brasil. Para tanto, o objetivo geral da pesquisa foi: Discutir as necessidades de cuidado no processo saúde/adoecimento do militar da Marinha do Brasil e os objetivos específicos: Descrever as características sociodemográficas e de autocuidado dos militares atendidos no ambulatório de cardiologia do HNMD; Identificar através dos depoimentos dos militares, as necessidades de autocuidado e; Propor estratégias de autocuidado em saúde aos militares. O referencial teórico utilizado foi o Modelo de Promoção de Saúde de Nola J Pender. Trata-se de um estudo misto de caráter exploratório e descritivo, realizado no ambulatório de Cardiologia do Hospital Naval Marcilio Dias, no município do Rio de Janeiro, no período de julho a agosto de 2014. Os sujeitos do estudo foram 20 militares hipertensos da Marinha do Brasil com idade acima dos 25 anos. Os dados foram coletados por meio de entrevista semiestruturada, em seguida, submetidos à análise de conteúdo de Bardin, emergindo três categorias e subcategorias assim denominadas: Primeira: Evidências de necessidades de autocuidado. Segunda: Identificação situacional da saúde dos militares com a subcategoria: A experiência do autocuidado para o militar com HAS. Terceira: Interesse pelo autocuidado com duas subcategorias: Interesse pelo aprendizado e Estratégias para o aprendizado do autocuidado. O perfil dos participantes caracterizou-se da seguinte maneira: Dos 20 militares, 19 são homens e 1 mulher, sendo 3 da ativa e 17 da reserva, a maioria são casados, idosos, de etnia parda e crença religiosa cristã, possuem ensino médio completo, com remuneração acima de 4 salários mínimos, residindo em local com saneamento básico. Quanto ao autocuidado referido pelos participantes: a maioria controla o uso de sal, ingesta hídrica adequada, utilizam alimentação balanceada, praticam algum tipo de exercício diário, a maioria referiu uso regular de anti-hipertensivos, e procura pelos serviços de saúde, quando necessário. Conclui-se que apesar do autocuidado referido, estes estão aquém às necessidades de saúde e não atendem às demandas de autocuidado necessária à manutenção da vida. Apesar de diversos fatores contribuírem para desmotivar os militares em relação ao autocuidado, eles apresentam interesse em aprender novas tecnologias de cuidar para adequação de sua saúde atual e melhora da qualidade de vida. Para atender às necessidades de autocuidado identificadas, sugere-se planejamento das ações estratégicas de promoção à saúde conjunta, com a equipe multiprofissional, instituindo a consulta de enfermagem, avaliação do autocuidado, prevenção dos fatores de risco e acompanhamento regular para análise das mudanças efetivas dos hábitos de vida saudáveis.

Regional Fisheries Advisory Committee 26th August, 1980

This is the report from the Regional Fisheries Advisory Committee meeting, which was held on the 26th August 1980. The report contains the minutes of the last meeting and a review of the Local Fisheries Advisory Committee including recommendations for these committees. The Fisheries Advisory Committee was part of the Regional Water Authorities, in this case the North West Water Authority. This preceded the Environment Agency which came into existence in 1996.

Intensive biological survey of the Glaze Brook catchment. Supplementary report on the water quality as indicated by macrophytes. August 1981

This is the Intensive biological survey of the Glaze Brook catchment: Supplementary report on the water quality as indicated by macrophytes produced by the North West Water Authority in 1981. This report describes the results of the macrophyte survey including data on their distribution and the prevailing water quality (nutrient status and toxic metal contamination) It supplements the initial report,TS-BS-81-3, which described the macroinvertebrate survey. The aim of this project is to describe the distribution of macrophytes within the river, paying attention to areas where weed growth may directly affect water quality or amenity usage, and describe the distribution of toxic metals. In the survey 16 sites of 500 m lengths of river were analysed, noting the relative abundance and percentage cover of the macrophytes present, plant score and Community Description Class (C.D.C.) were computed.
