José Antonio Marinho nasceu em Minas Gerais, em 1803, e morreu no Rio de Janeiro, em 1853. Em 1823, de passagem pela Bahia, envolveu-se nas lutas políticas daquele ano. Seguiu depois para Pernambuco, onde tomou parte, em 1824, na Confederação do Equador. Entrou para o Seminário de Olinda, mas denúncias de sua participação nos acontecimentos de 1824 impediram sua ordenação. Voltou, então, para Minas Gerais e conseguiu concluir sua formação sacerdotal. Ordenado em 1829, voltou às lides políticas, tornando-se advogado, jornalista e deputado provincial. Em 1836m elegeu-se deputado-geral por Minas Gerais, em 1842, tomou parte na Revolução Liberal, da qual foi primeiro historiador. Apesar de ter participado dos acontecimentos que historiou, tendo sido, por isso, acusado de parcial, o autor primou “pela verdade da exposição dos fatos”, como disse o Barão Homem de Melo. Com a autoridade de historiador da Revolução Liberal de 1842, Aluísio de Almeida afirmou que, sem a Historia do movimento politico, que no anno de 1842 teve lugar na Provincia de Minas Geraes, seria impossível escrever sobre aquele movimento. Obra rara, valorizada por treze litografias, que Aluísio de Almeida considera, com razão, “preciosas” : nove retratos, quatro vistas e uma planta, estas desdobradas. As litografias do primeiro volume se constituem de retratos do autor e de J. Feliciano, J. P. Dias de Carvalho e T. B. Ottoni, vistas da Praça de Barbacena, da Vila de Queluz e do Arraial da Lagoa Santa e planta do Arraial de Santa Luzia e suas imediações; e as do segundo volume de retratos de R. T. d’Aguiar, D.J. C. de Mendonça Franco, J. G. Teixeira de Carvalho, Diogo Antônio Feijó e Manuel Alves Branco e vista de Sabará.

Pisidium obtusale in the neighbourhood of Borka occurs in deep pools on upland bogs. The majority of water-bodies where this mollusc lives are temporary. Their bottoms are covered with sedges, and sometimes mosses occur. Evidently there is a marked attraction of P. obtusale to places overgrown by willow. In pools remote from scrub or woody vegetation it does not appear. Temporary water-bodies fill up with melt water in the middle or the end of April and finally dry up at the end of July or the beginning of August. Observations on the life cycle of P. obtusale started on 21 April 1966, following on the filling-up of the water-body by melt water. The findings of the study are presented in this paper.

Studies on the nutrient composition of smoked-dried Clarias gariepinus were carried out, to assess the effects of pest infestation on the dried catfish from two different market (Abakpa and Kpirikpiri market) area in Abakaliki Metropolis, Ebonyi State, Nigeria. Fish samples from the two markets where kept for pest to infest it and it were taken to Biochemistry Laboratory of Food Science and Technology in Ebonyi State University to assess the damage of pest on dried catfish using standard methods. There was a significant different among the mean weight of fish from the two markets (Abakpa and kpirikpiri; 19.13kg and 18.98kg respectively) compared with the mean weight of the control 20.09kg. There was a variation in the proximate composition of the fishes from the two markets compared with the control, the decreases of the proximate composition are: crude protein from 60.07% to 40.27%; fat from 8.35% to 5.90%; moisture content from 11.67% to 10.67; fiber from 12.93 to 11.93; ash from 4.02% to 3.54% and carbohydrate 12.67% to 5.89%. The longer the storage periods of the infested smoked fish the more the tissue was degraded. Proper handling and storage of dried catfish are required to prolong the shelf life and nutrient content of dried catfish.

The Quaternary cold periods in the Northwestern Pacific are thought to have heavily influenced the amount and distribution of intraspecific genetic variation in marine fishes. To estimate the demographic history and genetic structure of Lateolabrax macula

East African sun-dried fish infested by Dermestes maculatus were exposed to tropical sunlight at ambient temperature and analysed for insect mortality and weight losses. Solar treatment for 6 to 8 lo was highly effective for one layer of split sun-dried fish and 100% insect mortality was toted, while pest species were still present in the four layer batch. Weight losses between 1.2% and 10.2% were recorded, the top layer suffering the highest loss. The high surface temperature of 60°C caused fish to become brittle and quality losses occurred. A reduction in length of exposure/temperature is probably a presupposition for application of the method to local conditions.

East African sun-dried fish dipped for 4 seconds in different solutions of pyrethrum and piperonyl butoxide were analysed for insecticide residue limits. All analyses showed residues above the FAO/WHO MRL; exceeding factors of between 7.6 (22.9 ppm) and 1.6 (5.3 ppm) were found for pyrethrum while exceeding factors between 5.1 (102 ppm) and 1.7 (33.1 ppm) were common for piperonyl butoxide after 6 months storage at ambient temperature. All insecticide treated fish, regardless of dip concentration, were observed to be less susceptible to infestation by Dermestes maculatus than samples of untreated fish. No dry weight losses due to insect infestation were recorded, however moisture evaporation caused weight losses between 6 and 8% during the period. Further investigations showed that careful handling and a dip concentration more in accordance with FAO/WHO MRL than the commercial practice will reduce the cost of insecticides from K.sh. 0.72 to K.sh. 0.23 per kg pyrethrum treated fish.

Previously an asteroid starfish Astropecten indicus has been described by Tahera (1996), and another species of the genus Astropecten i.e. A. polyacanthus Muller and Troschel, 1842 has been collected from the subtidal region of a sandy shore of Clifton (24°47'42"N 66°59'6"E), Karachi. The latter species is here reported for the first time from the Pakistan coast of the northern Arabian Sea and fills the gap in the known distribution. The species is briefly described and illustrated.

Phyllophorus (Phyllophorus) maculatus new species is described from a depth of 22-45 meters near the western edge of the Yellow Sea. The body is cylindrical, with body wall ossicles present only in the anal region. Ossicles are four-pillared tables with low spires and indented disc margin. A revised key to the eleven phyllophorine (Family Phyllophoridae, Subfamily Phyllophorinae) species now known from China is presented.

La anchoveta es la especie clave de la cadena alimentaria del sistema de afloramiento del mar peruano, que se caracteriza por sus altos niveles de productividad no superados por ningún otro ecosistema marino. Se analizaron los principales aspectos biológicos de la anchoveta en periodos de abundancia del recurso, y cuando disminuyeron los niveles poblacionales de esta especie. La recuperación de la población de la anchoveta es rápida después de los eventos cálidos debido a que la población responde a la normalización de las condiciones ambientales, disminuyendo también su mortalidad
