| Com o objetivo de selecionar produtos efetivos contra o cancro estriado, foram conduzidos dois ensaios; no primeiro, procurou-se avaliar o efeito preventivo e no segundo, o efeito curativo. Foram testados os seguintes produtos: Mancozeb, Clorotalonile metalaxil-Mancozeb, Metalaxil e Captafol utilizado como padrao. Dentre os seis fungicidas testados, os produtos a base de Metalaxil, Ridomil e Ridomil-Mancozeb apresentaram bom desempenho no controle de Phytophthora spp., evidenciando os efeitos preventivo e curativo desses produtos. Com base nesses resultados, o Metalaxil-Mancozeb pode ser indicado como alternativa para o controle do cancro estriado. |

| Em 1994, na Estacao Experimental da UEPAE Porto Velho e em areas de produtores, plantas de seringueira apresentavam rachaduras na regiao do coleto. No local afetado havia acumulo de latex coagulado e o tecido necrosado atingiu a casca e, consequentemente, os vasos laticiferos, sem, contudo, danificar o lenho. O diagnostico de laboratorio revelou nao existencia de microrganismos patogenicos e inicio de cicatrizacao natural dos tecidos, descartando a possibilidade de doenca. O problema parece ser de ordem fisiologica, pois o porta-enxerto sofreu rachaduras e exsudacao do latex, o mal nao foi seletivo. Tal fato poderia ser explicado pelo acrescimo do volume de producao do latex em periodo chuvoso. Recomenda-se inspecao periodica nos seringais e pincelamento... |

| While only 4 species were known for the family Nannastacidae in West Africa, a recent study has revealed 11 more species - Procampylaspis maurini, P. arguini, P.thalassae, Cumella africana, Schizotrema atlantica, Campylaspis macrophthalma, C. mauritanica, C. bonetti, C. legendrei africana, C. jonesi. Of these, S. atlantica and the last 4 Campylaspis species are new species, and are described. Both male and female adults are described, with explanatory diagrams, and additional observations are included. The species of Campylaspis are incorporated modified form. It is thought that this description completes not only acquaintance with the fauna of the Saharian section of the Atlantic, but also the whole of the Atlantic Ocean. |

| Introduction : It is now clear that the world's fishery resources are being subjected to exploitation at or above their capacity to produce maximum sustainable yields. At the same time as these trends are being felt, there is a very large wastage of fishery resources from discarding unwanted catches at sea. At the end of each fishing operation a part of the catch is often returned to the sea after sorting by the fishermen. A 1994 FAO report provided an estimate of global discards in commercial fisheries of 27 millions of tons per year compared to 50 million tons of direct human consumption. A more recent FAO document estimated that discards were in the order of 20 million tons in 1997. The majority of the world's fisheries are multi-species in nature and... |

| A redescription of the genus Mustelus was undertaken in order to resolve the taxonomic confusion surrounding it. Metric characteristics, number of vertebrae, size and form of the teeth, colour, biology and geographical distribution are considered in description of the species M. mustelus (Linnaeus, 1758), Mustelus asterias Cloquet 1821, and M. mediterraneus new species, the several synonyms for each of which are listed. General remarks on each are made, and a final dichotomous key for identification is presented. |

| Confusion has arisen over the nomenclature of certain fish of the family Centracanthidia, because of the colour variations due to sexual dichromatism, sexual inversions, protogynous hermaphroditism, and seasonal modifications according to the stage of maturity. A historical survey of nomenclature is presented for species described under the genera Maena, Smaris and Spicara, the last being the most recent. A morphological study and an electrophoretic study of the crystalline lens of the various species involved is described. The techniques and standards used are given. As a result of the study, and bearing in mind the effects of the variations mentioned above, it was concluded from electrophoretic comparisons that only 2 species are valid, Spicara maena and... |

| Representative species of the families Pleuronectidae, Bothidae and Soleidae were studied throughout the year. Changes are described which were seen in the ovaries, and photographs of cross sections of the tissue are shown. The progress of egg release was noted, and in some cases correlated studies were made of gonadal changes in male. The period of egg release was prolonged over 1 one half -2 months for plaice and turbot, and for 6 months for sole. Individual fish showed these extended periods of laying, and the actual months of the year differed for each species. The massive mobilisation of reserves which necessarily accompanied the release of large numbers of eggs was reflected by turbot, in sperm production. In addition, the increase in gonadosomatic... |
