Differences in Dolphin Mortality Rates in Night and Day Sets for the U.S. Eastern Tropical Pacific Tuna Purse Seine Fishery

Because dolphins sometimes travel with yellowfin tuna, Thunnus albacares, in the eastern tropical Pacific (ETP), purse seiners use the dolphins to locate and capture tuna schools. During the process of setting the purse seine nets, dolphins often become entangled and drown before they can be released. Data for the U.S. purse seine fleet in the ETP during 1979-88 show that dolphin mortality rates in sets made during the night are higher than mortality rates in sets made during the day. Even with efforts to reduce nightset mortality rates through the use of high intensity floodlights, night set mortality rates remain higher. The data are also used to simulate a regulation on the fishery aimed at eliminating night sets and show that dolphin mortality rates would decrease.

Seventh Annual Report for year ended 31st March, 1972

This is the seventh Annual report of the Cumberland River Authority on information of its activities and responsibilities on river management in its area between the beginning of April 1971, to the end of March 1972. The report contains 5 main sections on water resources, land drainage, fisheries, pollution, and finally the expenditure and income for the 12 month period. The first area that the report deals with is water resources, which includes periodical surveys, hydrometric schemes, acceptable flows, conservation works and a review of rainfall and river flow. The section on land drainage looks at work on improvement schemes, floods, charges and information on maintenance work carried out on rivers including Wampool, Waver, Derwent and Eden. The fisheries section covers 5 districts of the River Eden, Esk, Ellen, Derwent and South West Cumberland. It includes angling information and a general report for salmon and sea trout, brown trout and freshwater fish. Fish disease and fish hatchery are also covered as well as fisheries protection and licence duties. The fourth section on pollution deals with water quality, and the results of samples taken for chemical analysis from rivers Eden, Eamont, Petteril, Caldew, Calder, Irthing, Esk, Irt, Mite, Derwent, Ehen, Wampool and Waver are also given. It also covers information on sewage and trade effluents. The River Authorities preceded the Environment Agency which came into existence in 1996.

Entre a capela e a catedral: tensões e reinvenções da identidade religiosa na experiência do protestantismo histórico atual

O trabalho analisa as transformações ocorridas nas igrejas protestantes históricas no campo religioso atual. A partir da análise de um estudo de caso feito em uma igreja histórica no Rio de Janeiro, a pesquisa busca compreender que elementos podem ser identificados na experiência religiosa desta comunidade, que indicam transformações em sua identidade religiosa. A reflexão parte de uma discussão sobre a própria noção de pentecostalização, que no contexto do campo religioso evangélico, tem sido utilizada como elemento que simboliza a disputa de identidade entre os grupos ligados ao protestantismo histórico e os movimentos pentecostais. O texto faz uma análise sobre as tensões existentes entre grupos tradicionais, ligados ao que foi chamado aqui de intelectualidade protestante, que faz uso do termo como categoria acusatória, ou seja, a pentecostalização para estes setores seria uma espécie de degeneração da tradição das igrejas históricas. A pesquisa visa repensar essa categoria que aparece no campo religioso, discutindo aspectos teóricos sobre a acusação aos pentecostais e sua influência no campo como uma religiosidade mágia que é enfrentada pela religiosidade intelectualizada presente na tradição histórica do protestantismo. A noção de pentecostalização utilizada na pesquisa aponta que para além dessa dicotomia magia (pentecostais) e religião (históricos), estão ocorrendo mudanças importantes na identidade religiosa evangélica, onde as igrejas históricas estão dialogando e resignificando elementos da matriz pentecostal com o objetivo de resignficar essas práticas a fim de dialogar com as mudanças ocorridas no campo evangélico atual, principalmente diante do crescimento do movimento pentecostal.

Festas e visitação religiosa em uma comunidade evangélica na Ilha Grande

Apesar de ser percebida como uma entidade supra-humana, a instituição Igreja é o resultado de um trabalho desenvolvido cotidianamente por indivíduos dedicados a tal empreendimento. Na Igreja Assembleia de Deus da vila Provetá, Ilha Grande, Angra dos Reis, RJ, esse trabalho contínuo vem sendo realizado com bastante êxito. O crescimento da vila foi concomitante ao crescimento da Igreja e seu corpo ministerial. Vinculado à sua história houve o processo de evangelização de grande parte dos moradores. Assim, a Igreja Assembleia de Deus Provetá detém uma clara hegemonia sobre o modo de vida local há pelo menos três gerações. Seu território é designado e percebido, tanto pelas pessoas dali, quanto pelas pessoas de fora, como um lugar regido por preceitos religiosos, cuja moral é predominantemente pentecostal. Este trabalho concentra-se na investigação acerca dos conjuntos da Assembleia de Deus, suas festas religiosas e desdobramentos. As festas e principalmente a organização e preparação das mesmas são veículos através do qual um cotidiano e/ou uma maneira de viver se manifesta. Tais práticas formam um complexo empreendimento que mobiliza grande parte da população local e revela dimensões sociais específicas. Ao delinear a forma com que a Igreja se inscreve na vida cotidiana dos fiéis, pode-se compreender de forma mais clara a interface entre religião e comunidade presente neste estudo de caso.

A Igreja no Brasil e o zelo pastoral de D. José Joaquim Justiniano Mascarenhas Castelo Branco: breve olhar sobre a implementação do catolicismo colonial e seus reflexos no sétimo episcopado carioca do século XVIII

A presente pesquisa aborda a formação da identidade da religião católica no Brasil colonial e seus reflexos nos desregramentos recorrentes na segunda metade do século XVIII, na diocese de São Sebastião do Rio de Janeiro durante o episcopado de D. José Joaquim Justiniano Mascarenhas Castelo Branco (1773 1805) tendo sido este o primeiro bispo a assumir o comando de sua diocese natal. O tema proposto aborda diretamente a complexa relação entre os poderes temporal, representado pelo Estado português personificado na figura da realeza , e o espiritual, pertencente à Igreja sua representatividade máxima no local varia de acordo com a posição ocupada pelos clérigos, respeitando-se, assim, a hierarquia eclesiástica (monges, freiras, padres, bispos etc.). Apesar da obrigatoriedade do catolicismo na colônia, a coroa metropolitana não foi capaz de dar o suporte necessário para o estabelecimento de uma religiosidade fiel às determinações do Concilio de Trento, conforme determinava o direito de Padroado. Isso levou à formação de um catolicismo colonial por vezes aparente. A miscigenação étnico-cultural deu brecha para o surgimento de praticas sincréticas e diferentes comportamentos sociais reprovados pela Igreja. O desvio de conduta era um problema que afetava, não só os fiéis, mas também o clero, sendo este composto na época por sacerdotes mal formados e alguns estrangeiros de índoles duvidosas. Assim, os bispos do Brasil do século XVIII tiveram que lidar com problemas que eram, na verdade, reflexo da realidade da estrutura colonizadora local onde, apesar de ter sido a Igreja uma importante aliada do Estado lusitano, e vice-versa, havia também grande rivalidade entre ambos. Dessa forma, ocorriam na época constantes embates entre as autoridades civil e religiosa, as quaisuniam-se e desuniam-se de acordo com seus interesses.

Does the California market squid (Loligo opalescens) spawn naturally during the day or at night? A note on the successful use of ROVs to obtain basic fisheries biology data

The California market squid (Loligo opalescens Berry), also known as the opalescent inshore squid (FAO), plays a central role in the nearshore ecological communities of the west coast of the United States (Morejohn et al., 1978; Hixon, 1983) and it is also a prime focus of California fisheries, ranking first in dollar value and tons landed in recent years (Vojkovich, 1998). The life span of this species is only 7−10 months after hatching, as ascertained by aging statoliths (Butler et al., 1999; Jackson, 1994; Jackson and Domier, 2003) and mariculture trials (Yang, et al., 1986). Thus, annual recruitment is required to sustain the population. The spawning season ranges from April to November and spawning peaks from May to June. In some years there can be a smaller second peak in November. In Monterey Bay, the squids are fished directly on the egg beds, and the consequences of this practice for conservation and fisheries management are unknown but of some concern (Hanlon, 1998). Beginning in April 2000, we began a study of the in situ spawning behavior of L. opalescens in the southern Monterey Bay fishing area.

Lunar, diurnal and tidal periodicity in relation to the prawn abundance and migration in the Godavari estuarine systems

Preliminary investigations to study the lunar, diurnal and tidal periodicity in abundance and migrations of prawns were made in the Bairavapalam distributary of the Goutami branch of the Godavari estuary during the period of November 1961 to July 1962. The study was based on observation of the catches of a stake net (bag net) operated near the mouth of the estuary. Records of the catches were maintained tidewise daily. Comparative estimates of abundance were made on the basis of catch per hour's operation. It was generally observed that the catches were higher during the darker half of the month than in the brighter fortnight. The landings during low tides were generally higher than those during high tides and usually heavier catches were made during nocturnal low tides than during the day low tides. A continuous inward and outward (immigration and emigration) movement of prawns of all size groups was observed in the estuary from November to July. In general, more penaeid prawns were found to be immigrating at dawn than at dusk. Similarly, the number of emigrants was also found to be generally higher during the new moon period than during the full moon. Metapenaeus monoceros showed an almost distinct nocturnal periodicity in migration, while no such periodicity was observed, distinctly, in other species. In the case of Penaeus indicus the movement of migrants was prolonged. In M. brevicornis the migrants were scarce till March and thereafter increased numerically. The migrant forms of Metapenaeus dobsoni continued to be abundant till May with peak periods in January and February. The migratory pattern of Metapenaeus affinis was similar to that of Metapenaeus brevicornis, though the migrants of the former species appeared a month earlier than the latter. Intensive studies over extended areas for longer periods are required to understand clearly the migratory pattern of the various species. The phenomenon of immigration of prawns can be clearly understood only by vital staining or tagging studies. Perhaps the emigrants might be returning with the succeeding changing life. To verify this, laboratory experiments, by vital stains, were conducted. The marked specimens, if released during the low tides on a large scale, may be recaptured during the subsequent high tides and the duration also may be calculated. At least some percentage of the emigrants remains in the sea for maturity and breeding.

Stock assessment and biology of Johnius glaucus (Day) off the northwest coast of India

The stock size and biology of Johnius glaucus (Day) resource off the northwest coast of India were studied for 1982-83 and 1983-84. The total length at the end of 6, 12, 18, 24 and 26 months was 121 mm, 183 mm, 237 mm, 261 mm and 264 mm respectively. The length growth parameters were: L∞=300 mm, K=0.0807 (monthly) and t(sub)0=-0.51 month. The weight growth parameters were: W∞= 317g, K=0.0762 (monthly) and t(sub)0= -0.41 month. The exploited stock mainly composed of 1/2 + and 1+ age groups. The annual Z, M and F were 2.34, 1.49 and 0.85 respectively. The l(sub)b, t(sub)b, l(sub)r, t(sub)r and selection factor K were 155 mm, 0.75 year, 65 mm, 0.25 year and 3.875 respectively. The Yw/R was optimum at the exploitation rate (E) of 0.75 and coded mesh size of 37 mm. The total stock for 1982-83 and 1983-84 was 14,624 and 26,190 tons respectively. The standing stock of 1982-83 and 1983-84 was 5,645 and 10,110 tons respectively. The MSY for 1982-83 and 1983-84 was 6,623 and 11,788 tons respectively. The F and Z were lowest in 0+ age group and highest in 1+ age group.

Some aspects of the biology of Otolithes cuvieri (Trewavas) and Johnius glaucus (Day) from Veraval

The length-weight relationship in O. cuvieri and J. glaucus can be described by the equations log W=-5.27997+3.13225 log L and log W=-4.93431+3.02556 log L respectively. The length at first maturity in O. cuvieri is estimated as 256 mm and in J. glaucus as 180 mm. Empty stomachs occurred in high percentage in both the species. A study on composition of food items revealed that O. cuvieri feeds on a variety of organisms while J. glaucus a selective feeder.
