Cestóides da ordem Trypanorhyncha em peixes de importância comercial capturados no litoral amazônico
(Universidade Federal do Pará, 2008) DIAS, Lilian de Nazaré Santos; MATOS, Edilson Rodrigues; http://lattes.cnpq.br/7895814591867510; PAIVA, Rosildo Santos; http://lattes.cnpq.br/0510818763187669
The purpose of this study was to identify the parasite fauna, particularly the cestode Trypanorhyncha the order, which affects market value of fish caught in Amazon coastal and assess the possible impacts on fisheries production industry. We examined 328 samples of five species of fish: Cynoscion acoupa, Macrodon ancylodon, Plagioscion squanosissimus, Centropumus undecimalis, Arius Parkeri. It made the measurement of its total length and weighing fish, filleting in the regions examined body, muscles and serous. The blastocyst, Trypanorhyncha were removed and sent for laboratory Azevedo Carlos. All species surveyed were parasitized by Trypanorhyncha, totaling 283 (73.78%) parasitized copies. The species Callitetrarhynchus gracilis showed higher prevalence parasite. Poecilancistrium caryophyllum was the most infect the species of fish studied, followed by Pterobothrium crassicolle and Pterobothrium heteracanthum and Callitetrarhynchus speciosum, infected Cynoscion acoupa and Arius Parkeri respectively. The regions abdominal muscles and backside were the most affected.

Dinâmica espaço-temporal da pesca industrial de camarão-rosa Farfantepenaeus subtilis na plataforma continental do Amazonas
(Universidade Federal do Pará, 2011-05-18) MARTINS, Déborah Elena Galvão; SOUZA FILHO, Pedro Walfir Martins e; http://lattes.cnpq.br/3282736820907252; CAMARGO-ZORRO, Mauricio; http://lattes.cnpq.br/5423657235023988
Knowledge of spatial distribution of fishing resources is essential to fisheries management. The southern brown shrimp Farfantepenaeus subtilis (Perez-Farfante, 1967) is an industrial fishing fleet target on the Amazon Continental Shelf. This study aimed to evaluate F. subtilis relative abundance spatial-temporal patterns from commercial fishery data, using Geographic Information System tools. Catch per unit effort (CPUE), used as index of relative abundance, was related to bathymetry, substrate characteristics, Amazon river flow and the oceanographic variables obtained by remote sensing: sea surface temperature and chlorophyll-a concentration. Analyzing substrate characteristics, the commercial shrimp trawls were concentrated at the mottled mud region, where the overlap of environmental factors was crucial for a higher incidence of F. subtilis. In this region, features such as substrate (mud), sedimentation rate (<1 cm.yr-1) and salinity (> 30) are the ideal habitat for F. subtilis. Higher CPUE values were associated with lower temperatures and higher values of chlorophyll-a concentration, which occur at the greatest flow of the Amazon river, during the first six months of the year. It was observed the occurrence of three periods with different levels of production along the year: from February to April, with higher CPUE of southern brown shrimp, from May to July, and August to September, with lower CPUE. The results showed that relative abundance of F. subtilis is not distributed uniformly in space nor in seasonal variation.

A importância da inovação e seus desdobramentos sobre a pesca industrial dos estados do Pará e Santa Catarina (Brasil)

Innovation is crucial to reach the socioeconomic development pursue by each country. Those that do not innovate or link innovation to their development agenda are left behind to the “centre”. This is so true, that developed countries are all more industrialized and innovative than those not developed. In Brazil this is also the case, despite being the sixth largest economy in the World, she is not a developed country, mainly because it occupies an intermediate position regarding manufacturing and innovation. This reflects throughout all activities including fisheries. Despite having a high productive potential extractive fishing when compared to other countries presents low production capacity, mainly due to the (un)willingness to adopt/develop innovative techniques that may enable a better performance. Another aspect that should be highlighted is its weak institutional capacity to promote sectorial development. In order to find alternatives to the current institutional structure of fisheries, Brazilian government, following institutional structures adopted by major fishing production countries, in 2003, adopted a new governance pattern for the sector. However, it did not change former structures. Therefore, remains relevant to identify those factors that make this important socioeconomic activity, hostage of market nuances and local circumstances that lead to inequality of the production assets of agents. In order to deeply understand it, this research in Brazilian states of Para (in the North/Amazon region) and Santa Catarina (in the South). Besides being the largest fishing producing states, are largely vulnerable to market behaviour and, at the same time present very unequal institutional frameworks and positions towards innovation. In order to compare the two states having in mind the role of innovation in the production process, an Innovative Performance Index was created based on multivariate analysis. Thus, primary data collected in the two states was submitted to a factor analysis. Results show that Santa Catarina's companies showed better results confirming the guiding hypothesis that innovation is the key to good performance at least in the fishing activity. Not forgetting that other context factors matter, including those institutional agents that closely follow domestic and international market dynamics. Another result that need to be highlighted refers to strategic skills of the entrepreneurs, that may perform better because can better cope with market complexity. Santa Catarina's entrepreneurs showed greater commitment to innovation reflected in the behaviour of their companies. These empirical results allow saying that a better integration of the institutions that coordinate agents involved in the fishing activity can create an environment that may promote a sound development of the activity and that this may apply to other sectors. This research deepened the discussion of the intricacies of innovation and its implications on development policy, allowing for strategic hints for those involved in regional and sectorial policy making.

Trabalho e trabalhadores da pesca industrial no Pará face à metamorfose do capital

Labor is going through a phase of transformation due to new types of technology and organization of the production process that in turn shape the production of goods worldwide. New organization models have taken place and have been connected with fordist practices, which have caused a major impact on the work force utilization in the production process. This study analyzed the fishery industry taking into account development features of this activity, the structure possessed by companies of this sector to be on the market and earn new markets, and the way workers are placed in activities such as fish catching and processing. Companies comprising the fishery industry from the Icoaraci District (the Iargest one in Pará State) were analyzed through the study of how the strategy adopted by processing companies and small fishery companies, in Iight of changes in customer market and decreasing of the main resources exploited, have an effect on the workers involved in such activities.
