The endogenous models of economic exploration observed in the Brazilian Amazon reflect a scenario of inequality and poverty. Rural aquaculture activity is being promoted, as a good source of protein and income diversification to try to reduce these disparities. Thus, the present work intends to address the difficulties and potentialities to achieve endogenous development through aquaculture. It is known that local development is dedicated to seeking self-sustainable growth in backward regions, which should occur based on the intensive use of science and appropriate technologies. Institutions are fundamental, as they allow for the incorporation of innovations that lead to the diversification of productive activities. Local actors need to be involved in strategies and goals, while communities need to participate in the management and control of development initiatives. In the Amazon, it is observed that endogenous development is generally involved in a slow process, which requires specific initiatives for the reality of each territory.

Recirculation aquaculture systems require proper food management, and feeding frequency is one of the most important factors to obtain optimal results in production. The tambaqui Colossoma macropomum presents satisfactory zootechnical performance in Pará State, but research related to its food management in recirculation aquaculture systems are scarce, in view of this, this work aimed to evaluate the zootechnical performance of tambaqui juveniles raised in Recirculation aquaculture systems. A total of 324 tambaqui juveniles with an average initial weight of 24.7 g were used in a recirculation system with three treatments in triplicate, with fish fed two, three and four times a day. The fish were fed with commercial ration with 32 and 36% of crude protein for 40 days and with a feeding rate of 4%. During the experiment were measured: temperature; pH; dissolved oxygen; pH; conductivity; turbidity; salinity, dissolved solids and nitrogen compounds of the system water, and these had a low variation between treatments. The fish fed with higher frequencies had higher final average weight and higher specific growth rate, with this, from the results obtained, it is concluded that the best feeding frequency for tambaqui juveniles is three times a day.

Artisanal or small-scale fishing is one of the oldest extractive activities in the lower Amazon region, generating income and subsistence for a good part of the riverside population. In this sense, the objective of the research was to characterize the fishing activity and socioeconomic structure of artisanal fishermen in the Costa Tapará community, Santarém, Pará State. Data collection was carried out through interviews with semistructured forms to 82 fishermen out of a total of 302 registered fishermen, during the period from March to November 2019. Data analysis was performed using descriptive statistics. The results showed that the average age of the fishermen was 37.6 (81.7%) years (± 11.5), 70.7% had incomplete primary education and 91.5% had fishing as their main source of income. The fishing activity is presented as artisanal and on a small scale, practiced in small wooden rowing and/or motorized boats, employing multiplicity of equipment highlighting the reed, mesh, and net. July and August stood out as the best fishing season. The biggest problems identified in the community were socioenvironmental conflicts. Understanding how this community dynamic works will directly contribute to the development of management alternatives and regional fishing sector planning.

The objective of the present work is to present the bioecological characteristics of the angelfish Pterophyllum scalare (Schultze in Lichtenstein, 1823) from a bibliographic review carried out through the search portals in CAPES Periodicals, Google Scholar, Scielo and ScienceDirect, using the scientific and common names of the species as keywords. After the selection and reading of the articles, the taxonomy, biology, ecology, fisheries and conservation status of the species were characterized. The angelfish is a freshwater fish from the Amazon basin that has great commercial importance, acquired mainly due to its exuberance (morphology and color) and for adapting very well to other species. It is an omnivorous fish, which inhabits bentho-pelagic environments, being easily found in rivers and streams with a high density of vegetation. It has a small size, reaching up to 15 cm in standard length. It presents several varieties of coloration commercialized in Brazil and in the world. It is a species that is not at risk of extinction, and its fishing and trade is permitted in accordance with current legislation. The angelfish is widely studied, but there is a gap regarding aspects of fishing.
本研究的目的是通过CAPES期刊、Google Scholar、Scielo和ScienceDirect等搜索门户网站对天使鱼Pterophyllum scalare (Schultze in Lichtenstein, 1823)进行文献综述，以该物种的学名和常用名称为关键词，展示天使鱼的生物生态学特征。通过文献的筛选和阅读，对该物种的分类学、生物学、生态学、渔业和保护现状进行了综述。神仙鱼是一种来自亚马逊盆地的淡水鱼，具有重要的商业价值，主要是由于它的丰富(形态和颜色)和适应其他物种的能力。它是一种杂食性鱼类，生活在底栖-远洋环境中，很容易在植被密度高的河流和溪流中找到。它的尺寸很小，标准长度可达15厘米。它介绍了几种在巴西和世界上商业化的色素。它是一种没有灭绝危险的物种，根据现行立法，它的捕捞和贸易是允许的。神仙鱼被广泛研究，但在捕捞方面还存在空白。

This study provided was carried out with the objective of determining the ideal stocking density for the rearing of tambaqui juveniles Colossoma macropomum, a fish native to the northern region of the Brazil that has favorable zootechnical and market characteristics for the development of regional fish farming. For this purpose, three stocking densities (100 fish per m³, 200 fish per m³ and 300 fish per m³) in triplicate, were evaluated in a completely randomized design for 68 days. The fish, with an initial average weight of 077 ± 0.01 g, were fed daily according to the feeding rate. Regarding the results, the growth variables showed a significant difference (P> 0.05), except for survival and feed conversion, with the treatment with animals stored in 100 fish per m³ showing the best performance between treatments. The stocking density of tambaqui juveniles is inversely proportional to weight gain, specific growth rate and average feed consumption. Therefore, it is suggested to cultivate the tambaqui juveniles in a water recirculation system at the stocking density of 100 fish per m³.

The objective of this study was to characterize the socio-economic profile of fish farming in the municipality of Bujaru (PA), through information of a social nature for producers and zootechnics of the production of the activity. Through non-probabilistic snowball sampling, questionnaires were applied to 30 fish farmers, performing image records during visits. The results were entered into the specific database, and submitted to descriptive statistical analysis (mean and standard deviation) in the BioEstat 5.3 program. Fish farming in Bujaru is carried out by male fish farmers (100%), most of whom are married (75%), with low education, exercising the activity for 5.10 ± 3.68 years. The production in the municipality is directed to species such as tambacu, pacu, tambaqui, pirapitinga, pirarucu and Nile tilapia, being carried out extensively, mostly in a family character, in excavated nurseries and igarapé channels, aiming at subsistence, commercialization and leisure. In addition to fish farming, producers develop other creations such as beef cattle, swine and poultry, as well as the planting of cassava, bananas and açaí. Regarding the inputs, the cost of the feed was costly and as for the acquired juveniles, many showed high mortality and heterogeneity in the lots. It also verified whether producers' dissatisfaction with public management in the activity, as well as their individualism, causing an obstacle to the development of the sector. The profile of the fish farming in Bujaru presented several obstacles, showing no potential for producers, due to the lack of technical assistance, lack of organization and incentive on the part of public policies in the activity.

Establish a minimum capture size to amazon catfish fished by bottom trawl nets in Northern Brazil is an alternative in order to reduce the impact on ichthyofauna and contribute to income generation for the fishing sector. Thus, this paper aims to discuss the need to standardize a minimum size of capture and propose alternatives for your use with commercial value, without increasing the current fishing effort and the impact on stock. Previous papers define that the size ranges of zoological length from 28 to 39 cm may present sexually mature individuals, its possible to use individuals with a size of 30 to 35 cm that are currently discarded at random, according to the fisherman's decision. The lack of pattern of minimum size represents a waste of fishing effort and usable protein of around 14%, which could have been used if the 30 cm length had been adopted. For this, we highlight the need for greater research efforts on the reproduction of piramutaba, considering the immense migration area of the species and the intense fishing pressure, which reflects on the life cycle of the species.
