Knowledge about fish behavior is crucial to be able to influence the capture process and the composition of the captured species. The rapid expansion of the use of underwater cameras made it easier to study the behavior of species. The videos made in this project were the result of several trawlings with six types of exclusion devices in artisanal trawlers with double-rig system. About 200 hauls were carried out between 2017 and 2020, during the implementation of the FAO/REBYCLAC-II - Sirinhaém-Pernambuco-Brasil project. The videos show that exclusion devices are effective in allowing fishes to escape, but they can nevertheless provide an escape opportunity for prawns. The fish showed a more regular pattern, they followed the meshes of the codend towards the mouth of the net until they found the devices, in all of them they forced the passage with caudal propulsion, with the exception of the aluminum grid where they presented three types of differents behaviors. The prawn, in the six devices, showed four patterns of behavior: “Front swimming”, “Escape to the back”, “Inert” and “Fixed in the inner meshs of the codend”. Observations with videos on the behavior of the species are essential to improve the efficiency of the bycatch exclusion devices.

The analysis of morphometry and length-weight relationships (LWR) contribute to the expansion of the set of information available for the conservation of fishery resources, being fundamental to mitigate the anthropogenic effects caused in the natural environment by artisanal shrimp fishing. The aim of this study was to analyze the morphometry and estimate the LWR for two species of fish of the family Carangidae (Oligoplites spp.) in an estuarine Amazon region, Northern Brazil. In the Guajará-Mirim estuary, the seasonality of the seasons (rainy and dry periods) mainly affects water salinity, with greater frequency of the O. saurus species in the rainy season and O. palometa in the less rainy one, the differences between the morphometric measures of the species of the genus Oligoplites captured by the shrimp trawl, indicate the occurrence of small individuals, with the species O. palometa showing negative allometric growth and O. saurus positive allometric, , being the first records of LWR estimates, contributing to the bioecological knowledge of the species.

In this review, we selected information necessary for epidemiological assessment of nutritional health. The review is divided into six themes: legislation that supports food and nutrition policies; the importance of epidemiological studies; evaluation criteria for the epidemiological profile of nutritional health; references for classification and assessment of nutritional health status; nutritional status related to the risk of nontransmissible chronic morbidities and methods for assessing the risk of malnutrition. Through this kind of study, it is possible to identify the nutritional health profile through anthropometric measurements and possible risks of malnutrition in the population.

This study aimed to review the scientific literature on studies carried out on the “discus” (Symphysodon aequifasciatus Pellegrin 1904). For this, a search for publications was carried out in four scientific databases (Periodicos da CAPES, Google Scholar, Scielo, ScienceDirect and Web of Science Core Collection), using the scientific and common names of the species as keywords. Articles were selected when they presented any of the keywords used in the title or abstract, excluding works from gray literature. After the selection of the articles in the scientific bases, a careful reading was carried out in order to characterize the biology, fishing and commercialization of the species. S. aequifasciatus, popularly known as discus, is an endemic species of the Amazon basin and its exuberant beauty makes it a target of great demand in the aquarium hobby. However, studies on the exploitation of this animal are scarce in free-living environments in the scientific literature. With the great demand for S. aequifasciatus, the production market grew mainly in Southeast Asian countries with a great demand for exports. From 2006 to 2015 S. aequifasciatus was exported a volume of 225,139 individuals and its price exceeds US$ 50 per unit value. Due to the great demand for S. aequifasciatus, its production method has been improving, from the cultivation of wild strains. It is noteworthy that, even being a highly commercialized species, the threat status is classified as "least concern", mainly due to the numerous studies carried out with the species.
本研究旨在回顾有关“铁饼”(Symphysodon aequifasciatus Pellegrin 1904)研究的科学文献。为此，在四个科学数据库(Periodicos da CAPES, Google Scholar, Scielo, ScienceDirect和Web of Science Core Collection)中进行了出版物搜索，以物种的科学名称和常用名称作为关键词。当文章出现标题或摘要中使用的任何关键词时，文章被选中，不包括灰色文献中的作品。在科学基地的文章选择之后，进行了仔细的阅读，以表征该物种的生物学，捕捞和商业化。S. aequifasciatus，俗称铁饼，是亚马逊盆地的特有物种，其旺盛的美丽使其成为水族馆爱好的巨大需求的目标。然而，在科学文献中，对这种动物在自由生活环境中的开发利用的研究很少。由于对水鱼的需求量很大，其生产市场主要增长在东南亚国家，出口需求量很大。从2006年到2015年，出口达225,139条，每单位价格超过50美元。由于对水棘鱼的需求量很大，其生产方法从野生菌株的培养开始不断改进。值得注意的是，即使是高度商业化的物种，其威胁状况也被列为“最不关注”，这主要是由于对该物种进行了大量的研究。

The use of photos and descriptions of fish otoliths is a useful tool for studies that include: systematics, taxonomy, identification of fish in the contents of stomachs and classification of the trophic chain. In this study. we characterized the morphology of the otoliths in nine species of fish, distributed in five families and two orders from the Verde River in the Upper Paraná Basin. An atlas was prepared depicting, by species, photography of the front and rear perspectives of each pair of sagittae otoliths. This visual atlas will help in later works that address ecology and, especially, in the distinction of species, thus contributing as an instrument to be applied to the taxonomic identification of species and fish populations.

We evaluated the structure of the ichthyoplanktonic assemblage (taxonomic composition, abundance, developmental stages, and relationship with local environmental variables) in marginal lagoons located in the clearwater Tapajós and Trombetas rivers, Amazon Basin, Brazil during periods of high water (rising waters and flooding). Samples were collected by means of horizontal drags in the subsurface of the water with a plankton net (300 µm mesh). Sorting, counting, identification of biological material, and classification of embryonic and larval stages were performed under a stereoscopic microscope. A total of 122 eggs and 2,813 fish larvae were captured and distributed in nine orders, 18 families, 20 genera, and 26 species. Of these, more than 75% are considered sedentary or short-distance migrants and more than 50% are of commercial interest. The results revealed fluctuating patterns of abundance and species composition between the lagoons of the two rivers. The ichthyoplankton community in the lagoons consisted mainly of larvae of native pelagic fish belonging to the Engraulidae family and larvae of benthic fish such as Eleotridae, making up more than 85% of the individuals captured in the study area. In addition to these two groups, some larvae of piranha species (Pygocentrus nattereri) stood out due to their high densities in the Tapajós river lagoons and croaker larvae (Plagioscion spp.) in the Trombetas river lagoons. The highest larval densities were recorded during the night with significant variations recorded in species composition. The presence of all stages of larval development indicates that these biotopes enable growth and are essential for the biological recruitment of fish species in the region. The ichthyoplankton showed a low correlation with the limnological variables, however, the patterns of abundance and composition of fish larval assemblages in the lagoons of the Tapajós and Trombetas rivers were preliminarily elucidated, although additional work is needed to assess the effects on survival and recruitment

The objective of the present study was to evaluate the effects of the aqueous extract of three herbal plants, Terminallia catappa, Camellia sinensis and Mentha piperita on the productive performance of Pyrrhulina brevis larvae. For the tests, a random design was used with five concentrations of aqueous extract of each plant (0, 0.25, 0.5, 0.75 and 1g L-1 ) and density of 10 larvae L-1 , with 4 replications, during 20 days of larviculture. The results showed that the use of the aqueous extract of T. catappa does not influence the increase in the zootechnical performance of the larvae, however, its use promotes better survival and uniformity of the batch. The use of aqueous extract of C. sinensis improves zootechnical performance at concentrations of 0.5 and 0.75g L-1 with an increase in weight and length, but does not influence the other parameters evaluated. And the use of M. piperita, in addition to promoting weight and length increment, improves uniformity and survival rates when used in concentrations equal to or greater than 5g L-1.

Sphenia fragilis is a bivalve mollusk, belonging to the family Myidae, which has a habit of digging unconsolidated or consolidated substrates. Its estimated distribution indicates the presence of the species in the eastern Pacific and western Atlantic oceans. The present study indicates the first occurrence of S. fragilis on the Amazon coast (Urindeua River, Salinópolis, State of Pará). Additionally, it presents updated data on the species biogeography on the Brazilian coast. Altogether, 309 specimens of S. fragilis were found between the years 2013 and 2016, at depths between 1 and 4 meters, always associated with the surface of oysters. Based on these occurrences, added to the records made available on the Global Biodiversity Information Facility - GBIF platforms and the speciesLink network, it indicates an expansion of the biogeography of S. fragilis on the Brazilian coast, extending between the state of Pará and Rio Grande do Sul
脆弱蝶是一种双壳类软体动物，属于蛹科，具有挖掘未固结或固结基质的习惯。其估计分布表明该物种存在于东太平洋和西大西洋。本研究表明脆弱S. fragilis首次出现在亚马逊河沿岸(Urindeua River, Salinópolis, State of par)。此外，它还提供了巴西海岸物种生物地理的最新数据。在2013年至2016年期间，在1至4米的深度(通常与牡蛎表面有关)发现了309个脆弱链球菌标本。基于这些事件，加上全球生物多样性信息设施(GBIF)平台和speciesLink网络提供的记录，表明巴西海岸脆弱沙螺的生物地理范围正在扩大，从帕尔州延伸到南里奥格兰德州

Based on these occurrences, added to the records made available on the Global Biodiversity Information Facility - GBIF platforms and the speciesLink network, it indicates an expansion of the biogeography of S. fragilis on the Brazilian coast, extending between the state of Pará and Rio Grande do Sul","PeriodicalId":338824,"journal":{"name":"ACTA OF FISHERIES AND AQUATIC RESSOURCES","volume":"21 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123570624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study reports the first occurrence of the invasive gastropod Melanoides tuberculata (Müller, 1774) in the state of Amapá. M. tuberculata was first detected in a lake in Praça Floriano Peixoto, a city park located in Macapá, the state capital, on May 2, 2022. The lake has a substantial amount of foliage on the banks and relatively turbid water (with a green tint). This environmental characteristic is similar to that found in existing literature. As a consequence of this detection, it can be surmised that M. tuberculata is spreading through the Amazon region – thus far, its presence was restricted to the states of Pará, Mato Grosso, and Tocantins. Due to the potential ecological and economic impact, it is considered necessary to monitor the population density of M. tuberculata in Amapá, as well as to investigate possible mitigation measures, such as the introduction of a native fish that is capable of feeding itself on this invasive species.
本研究报道了在美国阿马普州首次发现的侵袭性腹足类黑素瘤(Melanoides tuberculata, m ller, 1774)。结核分枝杆菌于2022年5月2日首次在位于该州首府马卡帕的城市公园普拉普拉塔弗洛里亚诺佩克托的一个湖泊中被发现。湖边有大量的树叶和相对浑浊的水(带有绿色的色调)。这种环境特征与现有文献中发现的相似。由于这一发现，可以推测结核分枝杆菌正在亚马逊地区蔓延——迄今为止，它的存在仅限于帕尔州、马托格罗索州和托坎廷斯州。由于潜在的生态和经济影响，人们认为有必要监测amapap的结核分枝杆菌种群密度，并研究可能的缓解措施，例如引入能够以这种入侵物种为食的本地鱼类。
