Aktivitäten des nationalen Fischereidatenerhebungsprogramms im Jahr 2004

Based on the EU Regulation 1543/2000 for the improvement of quantity and quality of fishery data the Federal Ministry for Consumer Protection, Food and Agriculture has initiated a national data collection programme, executed by three institutions, Federal Research Centre for Fisheries (BFAFi), Federal Agency for Ariculture and Food and the Federal Research Centre Agriculture, co-ordinated by BFAFi. In 2004 samples have been taken from 943 hauls during 29 commercial fishing trips; 357 000 fish have been measured. From 2002 to 2004 the number of length and weight and measurements, and age determinations could increased by 32, 65 and 156 % resp. Pilot inquiries have been carried out to prepare also the collection of economical date of fishing vessels and of fish processing plants from 2006.

Investment in the training of technologists for commercial aquaculture

The protein shortage in Nigeria is noted and the role of aquaculture (=fish farming) as a complement in increasing the dwindling food supply is registered. In addition, the manpower shortage especially in the technology cadre is noted and attributed to the lack of co-ordination and standard curricula especially in aquaculture. An inventory of tasks performed in the aquaculture industry was taken and these were classified and validated, then their final priority level was used to assess which ones were critical, important or desirable and which ones would result in disaster or not with inadequate mastery. Based on the above, recommendations are made that all critical and important tasks be included in the teaching curriculum for aquaculture in both theory and practicals: while it is advocated that all tasks listed be undertaken in fish farm operations. This will raise the competence of technologists to run the commercial aquaculture projects

Length-frequency estimation for yellowfin tuna (Thunnus albacares) caught by commercial fishing gear in the Eastern Pacific Ocean

ENGLISH: Methods of collecting samples for the purpose of estimating the numbers and weights of fish caught, by length interval, are described. Several models for two-stage sampling are described, and the equations for the estimators and their variances are given. The results from a brief simulation study are used to show the differences between estimates made with the different models. Estimators for the average weights of fish in the catch and their variances are also described. These average weights are used to provide improved estimates of the total annual catches of yellowfin taken from the eastern Pacific Ocean, east of 150°W, between 1955 and 1990. SPANISH: Se describen los métodos de recoger de muestreo para estimar el número o peso de peces capturados, por intervalo de talla. Se describen varios modelos para el muestreo de dos etapas, y se presentan las ecuaciones para los estimadores y sus varianzas. Se usan los resultados de un breve estudio de simulación para indicar las diferencias entre estimaciones realizadas con los distintosmodelos. También se describe un estimador para el peso promedio de peces en la captura y su varianza. Se usan estos estimadores para calcular estimaciones mejoradas de las capturas anuales totales de aleta amarilla tomadas del Océano Pacífico oriental, al este de 150°W, entre 1955 y 1990.

Fangversuche mit Trenngittern im Steert pelagischer Schleppnetze

1993 wurden im Institut für Fangtechnik erstmals Versuche mit Trenngittern (sorting grids) durchgeführt. In Fortsetzung dieser Versuche waren auf 357. Reise der "Solea" im August 1994 weitere Untersuchungen mit modifizierten Gitterkonstruktionen vorgesehen.

Could the library be dismantled/role of unique holdings in modern times

I have been asked by administration, how much of our collection could go into storage. They optimistically hoping for a room or two for faculty/staff offices, as some buildings need renovation or need to be closed due to safety issues. Clearly, much of the population believes that all/most library materials are available on-line – free. I will present the results of our survey’s of material held and available on-line and space “freed” thanks to archiving. How little space is freed.

Wavefront measurement of double-clad pulsed ytterbium fiber laser

Because of high efficiencies, compact structure, and excellent heat dissipation, high-power fiber lasers are extremely useful for applications such as cutting, welding, precision drilling, trimming, sensing, optical transmitter, material processing, micromachining, and so on. However, the wavefront of the double clad fiber laser doped with ytterbium is still unknown. In this paper, wavefront of a fiber laser is measured and the traditional Hartmann-shack wavefront sensing method is adopted. We measured a double clad fiber laser doped with ytterbium which produces pulse wave output at infrared wavelength. The wavefront shape and contour are reconstructed and the result shows that wavefront is slightly focused and not an ideal plane wavefront. Wavefront measurement of fiber laser will be useful to improving the lasers' performance and developing the coherent technique for its applications.

SAQUA - sistema baseado em software livre para análise do comportamento da qualidade das águas fluviais: aplicado à bacia do rio Paraíba do Sul.

Nesta dissertação foi desenvolvido o sistema SAQUA (Sistema para Análise da Qualidade das Águas Fluviais), que permite o acompanhamento dos dados de séries históricas de parâmetros físico-químicos para análise da qualidade de águas fluviais. A alimentação do sistema SAQUA se dá a partir do arquivo tipo texto gerado no Hidroweb, sistema de banco de dados hidrológicos da ANA (Agência Nacional de Águas), disponibilizado na internet. O SAQUA constitui uma interface que permite a análise espaço-temporal de parâmetros de qualidade da água específicos definidos pelo usuário. A interface foi construída utilizando o servidor de mapas Mapserver, as linguagens HTML e PHP, além de consultas SQL e o uso do servidor Web Apache. A utilização de uma linguagem dinâmica como o PHP permitiu usar recursos internos do Mapserver por meio de funções que interagem de forma mais flexível com códigos presentes e futuros, além de interagir com o código HTML. O Sistema apresenta como resultado a representação gráfica da série histórica por parâmetro e, em mapa, a localização das estações em análise também definidas pelo usuário, geralmente associadas a uma determinada região hidrográfica. Tanto na representação gráfica da série temporal quanto em mapa, são destacados a partir de código de cores a estação de monitoramento e a observação em que os limites estabelecidos na resolução CONAMA 357/05 não foi atendido. A classe de uso da resolução CONAMA que será usada na análise também pode ser definida pelo usuário. Como caso de estudo e demonstração das funções do SAQUA foi escolhida a bacia hidrográfica do rio Paraíba do Sul, localizada na região hidrográfica Atlântico Sudeste do Brasil. A aplicação do sistema demonstrou ótimos resultados e o potencial da ferramenta computacional como apoio ao planejamento e à gestão dos recursos hídricos. Ressalta-se ainda, que todo o sistema foi desenvolvido a partir de softwares disponibilizados segundo a licença GPL de software livre, ou seja, sem custo na aquisição de licenças, demonstrando o potencial da aplicação destas ferramentas no campo dos recursos hídricos.

Prism coupling of ultrashort light pulses into waveguides

We discuss coupling of ultrashort light pulses into waveguides by use of a prism waveguide coupler configuration. Theoretical analysis indicates that an extra loss induced by the short coherence times of ultrashort pulses, which has a strong effect on the reflected light and the optimum coupling condition, appears in the waveguide. Numerical simulations show that the reflectance strongly depends on the coherence times of ultrashort pulses. A method for realizing optimum coupling by compensating for the extra loss is proposed as well in this paper. A preliminary experiment of employing ultrashort pulses with different coherence times was carried out, and good agreement between theory and experiment was obtained.
