The objective of this study is to determine the infection status of nematode larvae and record epidemiological molecular data in commercial fish from the southeast Pacific off the central coast of Peru. Anisakiasis is a fish-borne zoonosis caused by Anisakis larvae, parasites of relevance in the fishery resources that have negative impact on public health. Between January 2012 to December 2014, 345 specimens of four fish species (Trachurus symmetricus murphyi, Scomber japonicus peruanus, Merluccius gayi peruanus and Seriolella violacea) were examined for Anisakis sp. larvae. A total of 997 Anisakis sp. larvae were found in the body cavity of 196 fish (total prevalence 53.7%, total mean intensity 5.08). After morphological analysis, 958 (96.08%) larvae were identified as Type I and 39 (3.92%) as Type II. Specimens were identified by molecular analysis of the mitochondrial cytochrome c oxidase subunit II (cox2) gene, confirming that A. pegreffii is the predominant species and the most important agent of human anisakiasis off the Peru Central Coast. In addition, we revealed the occurrence of A. physeteris (s.l.) in S. japonicus peruanus (P = 18.0%; MI = 2.17). Therefore, the results obtained in the present study improve the knowledge of the occurrence of Anisakis species in the commercial fish from the Southeastern Pacific Ocean, highlighting the importance of considering a potential hazard for humans and the necessity of further research in other fishes of greater preference by the Peruvian population. © 2021 Elsevier B.V., All rights reserved.
Socioeconomic impact of COVID-19 on Peruvian amazon aquaculture: a survey to fish farmers of the San Martín region

"The pandemic produced by COVID-19, is affecting all sectors worldwide. Aquaculture and fishing are not the exception. The measures taken by governments in order to dissipate contagions prevent supporting the economy. Faced with this situation, governments and state entities are taking measures to cushion and strengthen companies. However, to make correct decisions regarding aid, it is necessary to diagnose the state of the productive sectors in order to carry out interventions and manage solutions to priority problems. The objective of the present study was to establish information on the aquaculture production units in the San Martín region, which enables the aquaculture sector to be managed efficiently, promoting efforts and public interventions in the region. The results show that more than 90% of the aquaculture producers in the San Martín region are affected, mainly by logistical difficulties in the delivery of supplies, which have stopped the operation of approximately 18% of fish production. During the COVID-19 dormancy period, aquaculturists implemented some biosecurity measures, mainly handwashing, but it is necessary to establish protocols for good aquaculture production practices to strengthen health aspects that prevent the spread of the disease."
