ABSTRACT
Introduction: Anisakidosis is a zoonotic disease caused by the consumption of raw or undercooked fish or crustaceans parasitized by nematode larvae of the Anisakidae family. In this study, the presence of anisakid larvae was identified in fish species of consumer of the Pacific coast in Ecuador and Colombia. Methods: We obtained 438 samples grouped into twenty species of fish caught in the fishing ports of Manta, Santa Rosa, Buenaventura and Tumaco. The morphological identification of the larvae was made by taxonomy and the percentage of infection, were calculated. For the identification of species, a multiplex PCR was carried. Results: The taxonomic review identified eight species of fish as hosts of the genders Anisakis and Pseudoterranova. The larvae were isolated mainly from the intestine with a percentage of infection between 18 and 100%. The percentage of infection and identification of anisakids in these fish will aid in the prevention and control of anisakiasis as a possible emerging disease for this area of the Pacific. With the multiplex PCR, A. pegreffii, A. physeteris, and P. decipiens were identified. Conclusion: The identification of these species is reported for the first time in this geographical area, providing the basis for future research into the Anisakidae family.
Introducción: La anisakidosis es una enfermedad zoonótica causada por el consumo de pescado o crustáceos crudos o poco cocinados parasitados por las larvas de nematodos de la familia Anisakidae. En este estudio, se identificó la presencia de larvas de anisakidos en especies de peces de consumo de la costa del Pacífico en Ecuador y Colombia. Métodos: Obtuvimos 438 muestras agrupadas en veinte especies de peces capturados en los puertos pesqueros de Manta, Santa Rosa, Buenaventura y Tumaco. La identificación morfológica de las larvas se realizó por taxonomía y se calculó el porcentaje de infección. Para la identificación de las especies, se llevó a cabo una PCR múltiplex. Resultados: La revisión taxonómica identificó ocho especies de peces como huéspedes de los géneros Anisakis y Pseudoterranova. Las larvas se aislaron principalmente del intestino con un porcentaje de infección entre 18 y 100%. El porcentaje de infección e identificación de anisakidos en estos peces ayudará a prevenir y controlar la anisakiasis como una posible enfermedad emergente en esta área del Pacífico. Con la PCR múltiplex, se identifico A. pegreffii, A. physeteris y P. decipiens. Conclusión: La identificación de estas especies se informa por primera vez en esta área geográfica, proporcionando la base para futuras investigaciones sobre la familia Anisakidae.

BACKGROUND: The objective of this study was to report on the prevalence of musculoskeletal pain in lobstermen in the northeast USA. METHODS: Crews were randomly selected from those licensed to fish in Maine and Massachusetts and followed prospectively. The survey used a Nordic Musculoskeletal Questionnaire format to characterize musculoskeletal disorders. RESULTS: A total of 395 individuals participated. One half of the respondents reported low back pain. Back pain was attributed to or exacerbated by lobstering. Low back pain was prevalent among both captains and sternmen, while sternmen reported more hand/wrist pain than captains. Multiple locations for pain were common in individual participants. CONCLUSION: Equipment or technology to assist material handling should be a priority, as the body segments with high prevalence of pain (back, hand/wrists, shoulders, knees) are all affected by the repetitive and forceful handling of the lobster traps.

Resumo Introdução: a pesca é uma atividade perigosa, associada à elevada morbimortalidade. Entretanto, são escassos os estudos sobre lesões oculares em trabalhadores desta atividade. Objetivo: identificar lesões oculares relacionadas à exposição ocupacional na pesca comercial e possíveis fatores de risco e de proteção relacionados. Métodos: revisão de literatura nas bases bibliográficas MedLine, LILACS-BIREME, SCOPUS, Web of Science e Cochrane, utilizando os termos de busca "pesca" e "lesão ocular". Foram incluídos: artigos completos disponíveis escritos em inglês, português ou espanhol, publicados de abril de 1993 a abril de 2013; e estudos em seres humanos. Resultados: foram incluídos 18 artigos, provenientes de 12 países. O desenho de estudo mais prevalente foi o de corte transversal. Discussão: as lesões mais frequentes se relacionavam com a exposição solar excessiva, como a catarata e a degeneração macular senil, e com traumas oculares, principalmente as lesões perfurantes pelo gancho de pesca ou por fragmentos de animais marinhos. Esses agravos foram relacionados com fatores de risco como o manuseio de peixes e frutos do mar e as jornadas prolongadas de trabalho. De acordo com os estudos, a maioria das doenças oftalmológicas relacionadas ao trabalho da pesca é prevenível, o que indica a necessidade de políticas de promoção de saúde direcionadas para a população envolvida com esse ramo.
Abstract Introduction: commercial fishing is a dangerous activity which is associated with high morbimortality. However, there are few studies on fishing workers' eye injuries. Objective: to identify occupational ocular injuries in commercial fishing and possible related risk and protection factors. Methods: literature review on the databases MedLine, LILACS-BIREME, SCOPUS, Web of Science, and Cochrane through the searching terms "fishing" and "ocular/eye injury". Both were taken into account: full articles available in English, Portuguese or Spanish, published from April 1993 to April 2013, and research involving human beings. Results: 18 articles from 12 countries were included. Most studies were cross-sectional. Discussion: the most frequent injuries were due to excessive solar exposure, such as cataract and senile macular degeneration, and to ocular trauma, mainly perforations by fishhook or by fragments of marine animals. These injuries were associated with risk factors like fish and other seafood handling and long working time. According to the studies, most of the eye injuries related to fishing can be prevented, indicating the need for health promoting policies aimed at the population involved in this activity.
ABSTRACT
Este trabajo examina la relación entre el desarrollo de la pesca comercial marítima y el estudio de la fauna marina en la Argentina de fines del siglo XIX y las primeras décadas del siglo XX. Se analizan las investigaciones ictiológicas, la comercialización de productos marítimos frescos y las oportunidades que ofrecieron los mercados urbanos para la formación de colecciones. También se focaliza en los inicios de la pesca de altura que posibilitaría la captura y estudio de nuevas especies así como la acumulación de información sobre el ambiente marino.
This paper examines the relationship between the development of commercial maritime fishing and the study of marine fauna in Argentina between the end of the nineteenth century and the first decades of the twentieth century. It analyzes ichthyological research, the commercialization of fresh maritime products and the opportunities that urban markets offered for the creation of collections. It also focuses on the beginnings of deep-sea fishing, which would make it possible to capture and study new species as well as gather information about the marine environment.
