The participation of women in different areas of society is important for human reproduction and the development of various economic, social and cultural activities. The objective of this study was to reflect on woman participation in aquaculture in the Marajó archipelago (Pará - Brazil). The study was based on reports from five women who practice fish farming in the municipality of Curralinho, in March 2020. This methodology was the result of an extension project “Transfer of technology through training and technical assistance for fish farmers of tambaqui, Colossoma macropomum, in the archipelago of Marajó/PA”, from the Federal Institute of Education, Science and Technology of Pará (IFPA) Campus Breves. We observed that the creation of tambaqui in the region is also practiced by women, for subsistence. They have approximately 2 years of experience with fish farming. Most aquaculture companies are between 18 and 66 years old, have 2 to 4 children, with elementary education and are not part of any social organization. The training course on Good Management Practices in Fish Farming (BPM) aimed at strengthening the activity for the female group. In conclusion, women are protagonists of their own history and are present in the aquaculture universe, being important figures in the productive context in Marajó, Eastern Amazon.

The freshwater prawn Macrobrachium equidens, which is native species of the Indo-Pacific Region, was recorded for the first time on the Amazon coast of Brazil. This species was found to inhabit the same environment as two native Macrobrachium species, M. amazonicum and M. acanthurus, and is morphologically very similar to the latter. The identification of the species was confirmed by the genetic analysis of sequences of the mitochondrial Cytochrome Oxidase (COI) gene. A detailed description of the morphological features and reproductive biology of M. equidens in this new environment is presented.

The present study describes the morphological changes of the mouthparts and foregut of the freshwater prawn M. acanthurus that occur during the development of the larvae and first juvenile. The results indicate that the zoeae I have mouthparts with reduced setae and a structureless foregut that indicates obligatory lecithotrophic behaviour. There is an increase in the number of setae in these structures between the zoea II and the juvenile stage, indicating the adaptation of the organism for feeding. More complex structural alterations were observed in the first juvenile, which acquires benthonic habits, which ensure the capture and ingestion of a diversity of feeding resources found in the substrate.

Este trabalho teve como objetivo aplicar técnicas de Educação Ambiental (EA) aos estudantes da escola Adventista de Breves, Arquipélago do Marajó (Pará, Brasil), integrada aos assuntos da pesca e aquicultura. Foi utilizada a abordagem qualitativa e quantitativa. Para coleta de dados foi aplicado um questionário, palestras, atividade virtual de ensino/aprendizagem, demonstrativa e aplicação da escala hedônica facial, para 29 discentes do ensino fundamental. Os resultados indicam que o uso das técnicas de EA são importantes na escola, assim como o direcionamento para gerar mudanças de comportamento em relação ao meio ambiente. Foi possível identificar que 91% estudantes possuem conhecimentos sobre EA, uma parcela considerável não sabe que a pesca predatória pode acarretar a extinção de peixes, demonstrando que projetos de Educação Ambiental voltados para aquicultura são necessários para uma melhor conscientização ambiental.

The project "Technology transfer through training and technical assistance for tambaqui breeders (Colossoma macropomum) in the Marajó/PA archipelago is characterized by the opportunity for training, dissemination of technologies, quality academic professional training to students and others involved. For this, the municipality of Curralinho was the stage of extensionist actions realized by Instituto Federal de Educação, Ciência e Tecnologia do Pará (IFPA), Campus Breves. Active methodologies were used through the participation of teachers, fish farmers and students in the construction of pedagogical models. Thus, the objective of this work was to evaluate the use of different models for tambaqui creation. Three models were produced with perspective of implantation in different environments for the region of Marajó: floodplain area, dry land area and field area. A total of 13 fish farmers participated in this action, with whom the power of fixation attention, the understanding, the reflection and the sufficiency of time for each type of model built was evaluated. The Likert scale was used to analyze the data. The results showed that fish farming in floodplain areas presented the highest rates in the parameters studied, while the dry land area and field area models were less interesting in the opinions of the participants. In conclusion, the use of active methodologies through models improved the learning process of the fish farmers during the educational actions of the extension project in aquaculture.
