Regional Fisheries Advisory Committee 4th March, 1985

This is the report from the Regional Fisheries Advisory Committee meeting, which was held on the 4th March, 1985. The report contains sections on Public Water Supplies in West Cumbria, proposals for water supply for British Nuclear Fuels Limited (BNFL), and the proposals for a fish pass at Ennerdale Weir. The section on BNFL looks at the proposal of British Nuclear Fuels Limited to take more water from Wastwater. This section includes information about Wastwater, Calder Valley Boreholes, Mine Water and the River Ehen, and other groundwater investigations. 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.

Ciência e política: a aproximação Brasil-Argentina e a cooperação nuclear no subcontinente (1964-1985)

O objetivo geral da pesquisa é compreender por qual motivo e de que forma Brasil e Argentina optaram pela cooperação na área nuclear ainda durante seus governos militares. Segundo a literatura tradicional da área de Relações Internacionais, os ganhos relativos deveriam estar em evidência e, por conseguinte, impediriam a coordenação de posições em uma área tão importante para as estratégias de desenvolvimento e de inserção internacional dos dois países o que não se verificou na prática. Minha dissertação tem como meta entender o porquê. Da finalidade principal, decorrem objetivos específicos. São eles: lançar uma nova percepção acerca das relações Brasil-Argentina, ainda hoje encaradas primordialmente de acordo com padrões de inimizade e de desconfiança; compreender até que ponto as motivações dos países para o domínio da tecnologia nuclear estão relacionados a questões de segurança ou de desenvolvimento nacional; compreender quais foram as bases materiais e ideacionais que permitiram aos dois países integrar-se e, portanto, compartilhar soberania em um tema de high politics; demonstrar que a cooperação não é exclusividade de regimes democráticos; analisar a influência de grupos não políticos na formulação de políticas e do processo decisório; comprovar que não houve corrida armamentista na região ou a intenção de utilizar o aparato nuclear contra o vizinho. O recorte temporal deste trabalho partirá do final dos anos 1964, quando houve coincidência de regimes militares nos dois países, até o ano de 1985, quando a democracia é restaurada no Brasil. O marco temporal não é hermético, já que há referências anteriores a 1964, mormente no tocante à cooperação científica, e após 1985, quando a coordenação nuclear brasileiro-argentina é elevada a um nível superior, com o estabelecimento da ABACC. Na tentativa de responder às perguntas propostas, minha dissertação se baseia na análise de dois atores primordiais: o Estado e as comunidades epistêmicas.

Os livros didáticos de Geografia no período da ditadura civil-militar brasileira (1964-1985): quando o ensino serviu, em primeiro lugar, para forjar a ideia de país grande, país potência e em constante desenvolvimento

O principal objetivo da pesquisa foi averiguar o quanto o ensino da disciplina de Geografia, por meio dos manuais escolares, contribuiu para forjar a ideia de país grande e em constante desenvolvimento no período da ditadura civil-militar brasileira (1964-1985). Para isso, tornou-se necessário analisar a influência do mercado editorial, os processos educacionais do período, as legislações, os materiais adquiridos pelo(s) governo(s) e distribuídos entre as escolas e, consequentemente, analisar as ideologias que os governos militares pretenderam passar por meio das obras didáticas. Para viabilizar esse estudo, discutimos a importância da pesquisa em livros didáticos e desenvolvemos uma breve análise do uso dos manuais escolares em períodos anteriores e posteriores ao golpe, com a finalidade de investigar mudanças e permanências nos discursos ideológicos

Year-to-year changes of vertical temperature distribution in the California Current region: 1954 to 1986

Studies by Enfield and Allen (1980), McLain et al (1985), and others have shown that anomalously warm years in the northern coastal California Current correspond to El Niño conditions in the equatorial Pacific Ocean. Ocean model studies suggest a mechanical link between the northern coastal California Current and the equatorial ocean through long waves that propagate cyclonically along the ocean boundary (McCreary 1976; Clarke 1983; Shriver et al 1991). However, distinct observational evidence of such an oceanic connection is not extensive. Much of the supposed El Niño variation in temperature and sea level data from the coastal California Current region can be associated with the effects of anomalously intense north Pacific atmospheric cyclogenesis, which is frequently augmented during El Niño years (Wallace and Gutzler 1981; Simpson 1983; Emery and Hamilton 1984). This study uses time series of ocean temperature data to distinguish between locally forced effects, initiated by north Pacific atmospheric changes, and remotely forced effects, initiated by equatorial Pacific atmospheric changes related to El Niño events.

Preliminary observations on the availability of Tor tor (Hamilton) fry in the River Narmada near Hoshangabad, Madhya Pradesh

Collection of mahseer (Tor tor) fry during December to January from three centres of the river Narmada near Hoshangabad, (Joshipur ghat, Dungerwada ghat and Kherra ghat) using a special type of fry collection net is described. The physical features and physico-chemical conditions of the collection sites are also dealt with.

A note on the calorific values of a freshwater teleost, Labeo gonius (Hamilton)

Forty specimens of Labeo gonius (Ham) were analysed for protein, carbohydrate and fat values. The calorific value was calculated by multiplying the value of protein and carbohydrate with the energy factor 4.1 and for fat by 9.3. The average calorific values of fish for protein, carbohydrate and fat were 72.16, 9.55 and 11.90 cal/100 g respectively suggesting that the fishes are highly nutritious.

Determination of ubiquinone and tocopherol in heart, liver and muscle tissues of fresh water fish, Rohu (Labeo rohita, Hamilton)

The liver, heart and muscle tissues of Rohu, (Labeo rohita, Hamilton) were examined for their ubiquinone (UQ) and tocopherol contents. These three tissues contained respectively 11.60, 3.94 and 0.19 mg of ubiquinone and 10.16, 5.32 and 3.58 mg of tocopherol per 100 g. The 4% (V/V) of diethyl ether (EE) in light petroleum ether (PE) fractions of all three tissues on paper chromatographic separation gave spots having the same Rf value as standard ubiquinone-50 (UQ 10). Both the 4% and 6% (V/V) diethyl ether in light petroleum ether fraction of liver, heart and muscle tissues gave a single spot with the same Rf value as α – tocopherol.

Predation by Channa striatus (Bloch) on Rana tigrina (Daudin), Puntius gonionotus (Bleekeer) and Labeo rohita (Hamilton) in the laboratory

The growth performance of a predatory snakehead, Channa striatus was tested by supplying tadpoles of Rana tigrina and fingerlings of Puntius gonionotus and Labeo rohita as prey for a period of 21 days in aquaria. Prey consumption by C. striatus was significantly different (P<0.05) for different prey used (T1 - R. tigrina, T2 - P. gonionotus, T3 - L. rohita). Tadpoles of R. tigrina were preferred by the predator (C. striatus) over P. gonionotus and L. rohita although tadpole is nutritionally inferior to each of P. gonionotus and L. rohita. Each predator rayed on 50-330 mg per day per g of their body weight. Fish preyed on tadpoles also showed the highest growth. Significant difference in weight gain was found between T1 and T2 and also between T1 and T3 but no difference was found between T2 and T3. Food conversion ratio (FCR) was found to be lowest in treatment T3 followed by the treatments T2 and T1 respectively.

A histological study of the spermatogenesis in Ompok pabda (Hamilton-Buchanan 1822)

The present study deals with the histological analysis of testicular development in Ompok pabda. For the study, male gonads were collected month wise from January to September at Freshwater Station, BFRI, Mymensingh. From the analysis, 4 stages of sperm formation, namely, spermatogonia, spermatocytes, spermatids and spermatozoa, were distinguished. The percent distribution of spermatozoa was highest in July (about 92%). Maximum GSI value was 1.129±0.271 found in July. By analyzing the histology of spermatogenesis it was established that this species breeds once in a year.

The western Indian Ocean tuna fishery from 1980 to 1985: a summary of data collected by coastal states

Longliner and purse-seiner catch/effort statistics for tuna fisheries in the western Indian Ocean collected by Mozambique, Seychelles and Somalia are summarized. Although the data are not considered sufficient to indicate trends for the western Indian Ocean as a whole, an examination of data from the Seychelles EEZ shows that catch rates for yellowfin tuna declined consistently from 1982 to 1985, to about half their former levels. The data were processed by the FAO/Indo Pacific Tuna Development and Management Programme, Colombo, Sri Lanka.
