(Universidade Federal do Pará, 2012) ARAÚJO, Glauco Rivelino Ferreira de; SILVA, João Márcio Palheta da; http://lattes.cnpq.br/5356047514671129
This work deals with the migration process and the consequent territorialization of Northeastern fishermen Augusto Corrêa from the 1990s, that is, in the context of the lobster fishery that from this period was located in that municipality. The main objective was to analyze the influence of the lobster fishery in the migratory dynamics, population and spatial Augusto Correa municipality from 1990 to 2010. In addition to discussing and analyzing the relationship between growth rates and / or population decline and identify and understand the factors that contributed to the migration toward the northeast Pará, especially for the municipality mentioned; and also carrying out a mapping of the migratory dynamics of lobster fishing and its actors. Therefore, it held literature searches on specific institutions, followed by field visits, which empirically embasaram this work. The result was the realization of hypotheses on the subject, except one. Among the findings are the growth of the urban area of the municipal headquarters and its population and the existence of territorial conflicts in the local fishing scene. It is expected, therefore, that the analyzes and reflections in this work contribute to the knowledge and raise new and necessary inquiries and interpretations of the regional sociospatial.

The early larval development of the tropical reef lobster Enoplometopus antillensis Lütken (Astacidea, Enoplometopidae) reared in the laboratory
(2007-06) ABRUNHOSA, Fernando Araujo; SANTANA, Max William de Pinho; PIRES, Marcus Alexandre Borges
The early stages of the tropical reef lobster Enoplometopus antillensis Lütken, 1865 were described and illustrated in detail from specimens reared in the laboratory. Ovigerous females were captured in their habitat, at a depth of about 15 meters and transported to the laboratory. The larvae were reared in a recirculation water tank for approximately 15 days and then transferred to four 10 liters aquariums. The larvae were fed on Artemia sp. nauplii. Microalgae Dunaliella viridis was added daily to the culture. The larvae moulted seven times progressing through the zoea VIII. Megalopa stage was not achieved. The intermoulting period of each stage averaged from eight to 12 days. Morphological comparisons with previous reports are briefly discussed.

The early phyllosoma stages of spiny lobster Panulirus echinatus Smith, 1869 (Decapoda: Palinuridae) reared in the laboratory
(2008-02) ABRUNHOSA, Fernando Araujo; SANTIAGO, André Prata; ABRUNHOSA, Jacqueline Pompeu
The early stages of the Panulirus echinatus were hatched and reared in the laboratory. Ovigerous females were captured in their habitat and carefully transported to the laboratory. Larvae were transferred in a recirculation water tank at a density of 10 larvae.L–1. The larvae were fed on Artemia and gonads of mussel Brachydonts sp. Microalgae Dunaliella viridis was added at a concentration of 150 x 104 cel.mL–1. Larvae and exuviae of each zoeal stage were preserved in an alcohol 70% + glycerin (1:1) solution. The phyllosomas moulted eight times; the intermoulting period of each instar averaged about 7 to 10 days. The main morphological changes of each appendage were described in detail, illustrated and compared with previous reports.
