O estado de Sergipe não dispõe de uma versão eletrônica oficial do banco de dados de estatística de captura  disponível em boletins nacionais impressos. Assim, o objetivo desse trabalho foi atualizar a parte referente ao estado  de Sergipe de um banco de dados nacional eletrônico reconstruído, a fim de obter uma série histórica para 1950-2010,  analisando a composição da captura com maior resolução taxonômica e estimando componentes ausentes da pesca. As  capturas totais reconstruídas foram sempre mais elevadas do que as originais e indicaram um aumento nas capturas  de 1950 a 1979. Nas décadas de 1980 and 1990, foi observada uma estabilização nas capturas, e uma queda de 2005 a  2010. As capturas foram extraídas quase exclusivamente pela frota artesanal. A melhor resolução taxonômica permitiu  a identificação das seguintes espécies com as de maiores capturas em 2010 : Xiphopenaeus kroyeri, Mugil curema,  Ucides cordatus, Goniopsis cruentata  e Macrodon ancylodon . As capturas para essas espécies representaram cerca  de 50% do total extraído em Sergipe em 2010. Capturas recreativas foram estimadas em 16 t em 2010, e descartes anuais  em 818 t nas décadas de 1980 e 1990. Capturas ornamentais e de subsistência não foram estimadas. Nossa análise indicou  que perdas taxonômicas foram observadas em duas etapas: quando dados locais são incorporados em um banco nacional e  posteriormente, de um banco nacional para um internacional.

Efetuou-se estudo sobre os lipídios totais, ácidos graxos e colesterol presentes resíduos desidratados de camarão, visando o aproveitamento total do crustáceo na alimentação humana. Resíduos de camarão-sete-barbas (cefalotórax, segmentos abdominais e caudas) foram lavados com água clorada, cozidos, desidratados, moídos e o produto final analisado. O teor de lipídios totais encontrado foi de 2,66% e o de colesterol de 98,82 mg/100 g. Do total dos ácidos graxos 34,43% corresponderam aos ácidos graxos saturados, 30,30% aos monoinsaturados e 35,26% aos polinsaturados. Os resíduos desidratados de camarão podem ser destinados à alimentação humana como flavorizante natural, conferindo sabor e aroma característicos ao alimento. LEVELS OF TOTAL LIPIDS, CHOLESTEROL AND FATTY ACIDS IN THE DEHYDRATED RESIDUES OF THE SEVEN-BEARDS-SHRIMP (Xiphopenaeus kroyeri, HELLER 1862) CAPTURED IN THE STATE OF RIO DE JANEIRO Abstract The production of shrimps in Brazil grew significantly in the last years and with excellent conditions for expansion. Although it is appreciated in the cookery, the shrimp is considered a food of high cholesterol tenor. The shrimp residues, when submitted appropriately to the cooking process, following by dehydration and reduction of particles can be destined to the human feeding as a natural flavor substance, checking to the food, flavor and aroma characteristic of shrimp. Occurred study on the total lipids, fatty acids and cholesterol, presents in total use of the crustacean in the human feeding. Residues of seven-beards-shrimp (cephalotorax, abdominal segments and tails) were washed with chlorinated water, cooked, dehydrated and grinded. In the obtained product the levels of total lipids, cholesterol and fatty acids were determinated. The total lipids and cholesterol contents were 2,66% and 98,82 mg/100g. From the total of the fatty acids 34,43% corresponded to the saturated, 30,30% to the monoinsatured and 35,26% to the polinsatured fatty acids.

Landing data are the most basic information used to manage fisheries, although they are often unavailable or incomplete. The objective of this work was to reconstruct the national database of marine commercial landings for the Brazilian industrial and artisanal fisheries, from 1950 to 2015. Total landings increased strongly from 1950 to mid-1980s and suffered sharp decline in the early 1990s, mainly associated to the collapse of sardine fisheries. After that, another period of increasing landings was observed, but at a much lower rate. Industrial landings always surpassed artisanal landings in Brazilian waters, except for the beginning of the time series, when many industrial fleets had not started yet, and in the early 2000s, when a change in the methodology for collecting landing statistics was implemented in the state of Pará leading to an overestimation of artisanal landings. Artisanal fisheries have been declining since 2005, which is worrisome due to the social impact it may have on local income and food security. Regional differences were also observed, with industrial landings being always higher than artisanal landings in southeastern-southern Brazil, while the opposite was true for the northern-northeastern regions. Higher landings were observed in the southeastern-southern regions when both artisanal and industrial fleets were combined. Sardine and demersal fishes were the main resources landed by industrial fishers. Artisanal fishers caught more species than their industrial counterpart, featuring Xiphopenaeus kroyeri, Cynoscion acoupa, and Ucides cordatus. Although the fishing of Epinephelus itajara was banned in Brazil, it continues to be landed. Yet, catches of this species and others under some threat status are still not properly registered, including: Carcharhinus longimanus, Galeorhinus galeus, Sphyrna lewini, Sphyrna mokarran, Pristis pectinata, and Pseudobatos horkelii. Fishing resources not identified in previous landing reconstruction efforts, such as sea urchins and sea cucumbers, have now been reported. The database presented here should be continuously updated and improved. It is of paramount importance to resume the collection of landing statistics, including information on fishing effort, to assess the relative impact of fisheries and environmental factors on the main Brazilian fishing stocks.

O estado da arte dos estudos sobre a carcinofauna economicamente relevante para o Ecossistema Babitonga (EB) foi analisado a partir da compilação dos estudos publicados até o ano de 2016. No total foram compilados 21 trabalhos, incluindo periódicos científicos (57%), literatura cinza (33%) e livro (10%). O texto sintetiza o atual conhecimento sobre as espécies de siris (Callinectes danae e C. sapidus), caranguejo-uçá (Ucides cordatus) e seis espécies de camarão (Artemesia longinaris, Farfantepenaeus brasiliensis, F. paulensis, Litopenaeus schmitti, Pleoticus muelleri, Xiphopenaeus kroyeri), destacando aspectos bioecológicos, socioeconômicos, ameaças naturais e antrópicas bem como instrumentos para a gestão destes recursos pesqueiros. Espera-se que esta revisão forneça subsídios que contribuam com o direcionamento de estudos futuros, buscando a boa gestão destes recursos no Ecossistema Babitonga.

Various authors have emphasized the spatial information resident in an electron micrograph taken with adequately coherent radiation. In view of the completion of at least one such instrument, this opportunity is taken to summarize the state of the art of processing such micrographs. We use the usual symbols for the aberration coefficients, and supplement these with £ and 6 for the transverse coherence length and the fractional energy spread respectively. He also assume a weak, biologically interesting sample, with principal interest lying in the molecular skeleton remaining after obvious hydrogen loss and other radiation damage has occurred.

Two methods of identifying language disordered children are examined. Traditional approaches require attention to relatively superficial morphological and surface syntactic criteria, such as, noun-verb agreement, tense marking, pluralization. More recently, however, language testers and others have turned to pragmatic criteria focussing on deeper aspects of meaning and communicative effectiveness, such as, general fluency, topic maintenance, specificity of referring terms. In this study, 54 regular K-5 teachers in two Albuquerque schools serving 1212 children were assigned on a roughly matched basis to one of two groups. Group S received in-service training using traditional surface criteria for referrals, while Group P received similar in-service training with pragmatic criteria. All referrals from both groups were reevaluated by a panel of judges following the state determined procedures for assignment to remedial programs. Teachers who were taught to use pragmatic criteria in identifying language disordered children identified significantly more children and were more often correct in their identification than teachers taught to use syntactic criteria. Both groups identified significantly fewer children as the grade level increased.
