Spawning pattern of the Nematopalaemon hastatus (Crustacea: Palaemonidae) (Aurivilius, 1898), exploited in the artisanal shrimp fishery in the outer Cross River estuary

Some aspects of the reproduction of Nematopalaemon hastatus in the artisanal shrimp fishery in the outer Cross River estuary (Nigeria) was investigated. 2 kg samples were taken from the daily catch of the N. hastatus fishery on a twice-weekly basis. The N. hastatus in the sample were then observed for gravidity, using a hand lens, and their post-orbital carapace length (POCL) taken. This was done over a 12-month period. The eggs in formalin-fixed samples showed colour changes from light orange to dark brown with maturation. Gravid females with eggs in different stages of maturation, from light orange to dark brown were observed in the samples. The reproduction occurs all year-round. The proportion of gravid females observed in samples had two distinct peaks in June and November, and two distinct troughs in May and October. The lowest length at which gravidity was observed was 6.0 mm POCL. There were no Penaeus notialis in the samples

Regulation in Uganda's Lake Victoria fishery: historical and contemporary conditions

This paper sets out to explore how Uganda's lake Victoria fishery has been managed. It explores the management of the fishery during the protectorate period, and argues that the apparent success of regulation during this time may be attributed to the very heightened controls arising from Sleeping Sickness Controls. Once these were removed, entry into the fishery was rapid and uncontrolled, and the resultant impact on fish stocks was quickly felt. With its huge area, considerable shoreline, and innumerable islands, the lake Victoria fisheries service was quickly overwhelmed and disbanded as a result. In the early independence years, the Republic's government focused on developing the fishery, plans thwarted by turmoil of, and following, Idi Amin's reign. More recently, the fishery has prospered from Uganda's entry into the Nile perch fillet export market, which ahs adversely affected stocks. We present and comment on recently collected data that considers fishers' impressions of the status of the fishery, regulations and future managerial possibilities, and comment on these in the light of recent changes to Uganda's fisheries administration

Absorption of food in the black-jaw tilapia, Sarotherodon melanotheron (Ruppell) from a small tropical man-made lake in Ibadan, Nigeria

The carbohydrate, protein and lipid contents of the food ingested and their absorption in the intestine of Sarotherodon melanotheron inhabiting Awba lake in Ibadan, Nigeria, were investigated. Total carbohydrates of the ingested food ranged from 39.33 to 55.38% (mean = 48.70% while total protein and total lipid ranged from 10.10 to 17.13% (mean = 12.91%) and 7.79 to 8.96% (mean = 8.28%) dry weight, respectively. Calculated total percentages absorbed were 54.86-62.01 (mean 58.07) carbohydrates 47.33-54.06 (mean = 50.43) protein and 43.27-52.23% (mean 46.56) lipid. Absorption of protein and carbohydrate occurred mostly in the fore-gut (the first one-third of the intestine), while lipid was mostly absorbed in the mid-gut (the second one-third of the intestine). Dietary carbohydrate, protein and lipid contents of the food as well as the absorptive capacity of the intestine for these components of the food varied with size of fish

Valoración nutricional en pacientes quirúrgicos

[ES] Numerosos estudios han demostrado que muchos de los pacientes que ingresan en Cirugía presentan signos de malnutrición. En el presente trabajo se estudió re t rospectivamente la valoración nutricional de 116 pacientes. Los resultados muestran que sólo en el 29,3% de los enfermos se determinaron parámetros antropométricos, en el 19% parámetros bioquímicos y en el 25% parámetros inmunológicos de interés nutricional. Cabe destacar que, como también indican otros autores, la valoración nutricional no constituye todavía un procedimiento habitual en la práctica clínica.

Manuais do professor do ensino médio: imagens discursivas de professor e de ensino de ELE

O estudo situa-se no âmbito das investigações voltadas para documentos que sistematizam o trabalho do professor, dentre eles, o manual do professor que organiza a atividade docente junto ao livro didático. A dissertação analisa manuais do professor dos livros de espanhol selecionados pelo MEC para serem distribuídos a professores, em 2005, em função da lei 11161 da obrigatoriedade do ensino da língua espanhola para o ensino médio em todo o território nacional. O objetivo foi identificar imagens discursivas de docente e de ensino de espanhol como língua estrangeira neles construídas. Os fundamentos teóricos adotados advêm da Análise do Discurso de base enunciativa, além de recorrermos aos conceitos de dialogismo (BAKHTIN, 1979) e de polifonia (BAKHTIN, 1979; DUCROT, 1987). Os resultados nesses manuais apontam para a construção de imagens de professor como: aquele que necessita ser guiado em sua tarefa, incapaz de realizar suas escolhas em sala de aula, um professor recebedor de ordens; desatualizado com as metodologias de ensino atuais, necessitando, portanto, de atualização profissional; há ainda um professor que busca instruções facilitadoras para seu trabalho. Já no que se refere à visão de língua, deparamo-nos com um manual que dá ênfase ao trabalho com a leitura, voltado para uma concepção que valoriza aspectos discursivos; outros que afirmam seguir a abordagem comunicativa, com um olhar para a língua em uso, porém adotam procedimentos pautados numa concepção de língua como estrutura e/ou misturam ambas perspectivas

Französische Bemühungen um Erhaltung des Störbestandes sollten unterstützt werden

Der vereinzelte Fang markierter Störe (Acipenser sturio L.) im Bereich der Deutschen Bucht - die bisher letzte Meldung stammt aus dem Juni 1989 - gibt Anla0, auf französische Bemühungen zur Erhaltung dieses stark vom Aussterben bedrohten "Naturdenkmals" hinzuweisen und die deutsche Fischerei, insbesondere die kleine Hochsee- und Küstenfischerei um Unterstützung der Erhaltungsmaßnahmen zu bitten.
