RESUMO. Devido à escassez de trabalhos relacionados ao parasitismo no mundo, sendo assim, percebe-se a importância de realizar uma revisão bibliográfica em artigos científicos, dissertações e teses em bancos de dados e periódicos de fácil acesso para os estudantes e pesquisadores acerca das ocorrências de parasitas em M. mola entre os anos de 1904 -2017. A espécie de peixe conhecida popularmente como peixe lua (Mola mola: Molidae) são encontrados em todos os oceanos do mundo. O parasitismo pode ser uma das possíveis causas de encalhe desta família no Brasil, uma vez que existe um número de publicações cientificas reduzida de relatos de ocorrência da espécie M. mola. Foram encontrados 51 trabalhos relacionados a parasitos da espécie Mola mola no mundo, no estudo foram registradas 44 espécies de parasitos e 9 espécies são sinônimos, ou seja, são parasitos conhecidos por mais de um nome. O estudos possibilitou encontrar a ocorrência de parasitária em M. mola nos cinco filos e nos cinco continentes, destes houve maior registro de ocorrência parasitária na Europa nos filos Platylhelminte (n=28), Arthopoda (n=15) e Nematoda (n=1) e na América os filos Acanthocephala (n=1), Platylhelmintes (n=27) e Arthopoda (n=15), Oceania Platylhelmintes (n=7), Nematoda (n=1) e Arthopoda (n=14), na Ásia foram registrados os filos Platylhelmintes (n=3) e Arthopoda (n=5), na África foram registrados estudos apenas no filo Arthopoda (n=10) e algumas espécies os artigos científicos não identificaram o localidade do parasito encontrado impossibilitando de registrar o continente (NI) apresentou registro de parasitos nos filos Platylhelmintes (n=7), Arthopoda (n=3). Percebe-se a importância dos trabalhos de revisão de literatura, pois facilita o trabalho de futuros pesquisadores em agilizar a pesquisa.Palavras chave: Parasitismo, peixe sol, platelmintos, sunfish Check List of the parasites of the ocean sunfish (Mola mola: Molidae) fish in the world ABSTRACT. Due to the scarcity of works related to parasitism in the world, it is important to carry out a bibliographic review of scientific articles, dissertations and theses in databases and journals that are easily accessible to students and researchers about the occurrence of parasites in M. spring between the years of 1904 -2017. A species of fish popularly known as moon fish (Mola mola: Molidae) has been found in every ocean in the world. Parasitism may be one of the next causes of family sweeping in Brazil, since there are a number of reduced scientific reports of occurrences of M. mola species. The studies made it possible to find parasitic occurrence in M. mola in the five phyla and in the five continents, of which there was a higher parasitic occurrence in Europe in the Platylhelminte (n = 28), Arthopoda (n = 15) and Nematoda (n =1), and in America the phyla Acanthocephala (n = 1), Platylhelmintes (n = 27) and Arthopoda (n = 15), Oceania
The coast of the semi-arid region of Brazil is known for the presence of large estuaries inhabited by numerous species of edible bivalve mollusks. The oyster C. rhizophorae is naturally found in estuarine environments along the Brazilian coast, fixed on substrates, mainly in the roots of mangroves. Protozoa of the genus Perkinsus are important parasites of marine bivalves, sometimes causing significant pathological damage throughout the world. This study reports the occurrence of parasites Perkinsus sp. in mangrove oysters from Porto de Mangue estuary (Rio Grande do Norte state) and Icapuí estuary (Ceará state), two estuaries of the semi-arid region of Brazil. In Porto do Mangue estuary, oysters were collected in December 2016, January and February 2017. In Icapuí estuary, oyster sampling occurred in September, October and November 2017. Two fragments of the gills were incubated in Ray's Fluid Thioglycollate Medium - RFTM. The ecological and parasitological parameters were calculated. Five of the ninety oysters collected in Porto do Mangue estuary were parasitized, which corresponded to a mean prevalence of 5.6%, and in Icapuí estuary 18 of the 120 oysters collected were parasitized, which corresponded to a mean prevalence of 15.0%. The intensity of infection by Perkinsus sp. ranged from very mild to mild.
Ictioparasitology is a science that has, among its objectives, assisted in the understanding of the interactions between fish and their parasites. Crustaceans are one of the most popular invertebrate groups exhibit a striking diversity of forms, habits and sizes, are found at all depths in the various marine and freshwater of the earth, and Copepod class are the largest group crustacean parasites in fish, with economic importance, which may result in high mortality. In the present work the biodiversity of the parasitic copepods of skipjack tuna (Katsuwonus pelamis) from the Southwest Atlantic Ocean -Rio Grande do Norte, Brazil, is reported. Parasitic ecological indexes (prevalence, mean intensity and mean abundance) were also calculated. Fish were collected in the coastal area of Areia Branca (state of Rio Grande do Norte) from 2015 to 2016. Standard biometrics of the hosts was also taken. Four species were identified infecting branchial chamber and body skin of K. pelamis.: Caligus pelamydis (17.65%), C. bonito (36.27%), C. productus (37.25%) and Pseudocycnus appendiculatus (8.82%).
On rocky shores, macroalgae play an ecological role as organizer of community structures, since they are source of food for many invertebrate species inhabiting their fronds, as well as providing shelter from predators, enhancing environment conditions and reducing water movement. With this in mind, detecting new species on a regional scale is of major importance for biodiversity monitoring and conservation. In the current study, a first record of the seaweed species Acetabularia myriospora was made in the offshore of Ceará state, Brazil. The frequency of occurrence of A. myriospora (1.62%) is considered low whether compared to that of A. calyculus (17.43%). This study is the first record of the species Acetabularia myriospora (Polyphysaceae, Chlorophyta) in the coastline of Ceará state.
The aquatic environment facilitates the horizontal transmission of pathogenic agents. The protozoa parasites of the genus Perkinsus cause an epidemic disease of marine bivalves throughout the world, often causing mortality in populations of molluscs. This study reports for the first time the presence of Perkinsus sp. infecting Crassostrea rhizophorae from the coast of the state Rio Grande do Norte. The samples of mangrove oysters (Crassostrea rhizophorae) occurred in summer, in December (N = 10) of 2016, January (N = 40) and February (N = 40) of 2017 from the estuary Porto do Mangue. Two fragments of the gills were incubated in Ray's Fluid Thioglycollate Medium -RFTM. The ecological parameters parasitological were calculated. Were found parasitized five of the ninety oysters collected in porto do mangue estuary, which corresponded to a mean prevalence of perkinsose of 5.56%. The intensity of infection by perkinsose ranged from very light the mild.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
