“…False positives stemming from inadequate field and laboratory controls or insufficient testing for contamination of negative controls (e.g. relying on no visible bands on an agarose gel; see Simpfendorfer et al, 2016; Bonfil et al, 2021) in historically occupied, non‐core range habitats could have substantial, and potentially damaging, repercussions for the management of P. pectinata ; for example, they could prematurely suggest full recovery. A high frequency of samples in a study area of interest that meet some, but not all three analysis criteria may merit further investigation however, through additional eDNA surveys and other lines of research.…”

“…ddPCR™ assays offer greater sensitivity (Baker et al, 2018; Lehman et al, 2020; Drymon et al, 2021) and more precise quantification of target DNA when compared to conventional PCR (e.g. Simpfendorfer et al, 2016; Bonfil et al, 2021) or quantitative PCR approaches (see Wood et al, 2019; Cooper et al, 2021), making them ideal for ‘early detection’ surveys targeting highly threatened species.…”

1. Formerly common in tropical and subtropical waters of the Atlantic Ocean, the Critically Endangered smalltooth sawfish, Pristis pectinata, underwent severe declines over the past century, restricting population(s) to south and south-west Florida in the US, and Bahamian waters.2. Anecdotal evidence (e.g. encounter reports from the public) suggests that P. pectinata have recently been observed in historically occupied US waters; however, no directed surveys have been conducted to verify their extent of occupancy.3. Here, environmental DNA (eDNA) surveys were used to investigate the occurrence of P. pectinata in three formerly occupied estuaries in US waters.Water samples were collected in the summer from the Indian River Lagoon and

State-of-the-art of data analyses in environmental DNA approaches towards its applicability to sustainable fisheries management

2023

View full text Add to dashboard Cite

An increasing number of studies using marine environmental DNA (eDNA) approaches are showing its potential application in marine fisheries management by helping and simplifying some of the labor-intensive traditional surveys required to assess exploited populations and ecosystem status. eDNA approaches (i.e. metabarcoding and targeted) can support to ecosystem-based fisheries management by providing information on species composition; surveillance of invasive, rare and/or endangered species; and providing estimates of species abundance. Due to these potential uses in fisheries and conservation sciences, the number of studies applying eDNA approaches in marine habitats has expanded in the very last few years. However, a lack of consistency across studies when applying pipelines for data analyses, makes results difficult to compare among them. Such lack of consistency is partially caused by poor knowledge in the management of raw sequences data, and analytical methods allowing comparative results. Hence, we review here the essential steps of eDNA data processing and analyses to get sound, reproducible, and comparable results, providing a set of bioinformatics tools useful for each step. Altogether this review presents the state of the art of eDNA data analyses towards a comprehensive application in fisheries management promoting sustainability.

“…Específicamente en Tecolutla, Veracruz hay escasos reportes sobre la riqueza biológica y el estado de salud de los organismos acuáticos y no existe reporte sobre la vulnerabilidad de los organismos marinos del sistema. Así mismo, es una zona descuidada y desprotegida en materia de legislación ambiental y estudios de protección a los recursos acuáticos (Bonfil et al, 2021;Jerónimo-Juárez et al, 2020;Ramírez-Trejo et al, 2019;Rivera-Arriaga, 2017).…”
