Analysis of a coastal North Sea fish community: Comparison of aquatic environmental DNA concentrations to fish catches

“…A second fyke (53°00′28.42″N, 04°47′51.42″E) at Schanserwaard is located 1 km northeast of the jetty. Results of daily Stuifdijk catches over almost 60 years are available (van der Veer et al, 2015), and for the majority of the fish species, yearly trends were similar among kom fykes at three locations including Stuifdijk and Schanserwaard (van der Meer et al, 1995; der Veer et al, 1992).…”

“…The sampling procedure for the Stuifdijk fyke catches has already been described in detail (van der Veer et al, 2015). Catches based on 24-hr fyke fishing were collected daily over 10 weeks, from 16 April till 2 July 2015.…”

“…Continual measurements of fish fauna are essential to track the use of the area and to detect changes over time. Therefore, fish fauna has been monitored (figure 1 in Jager et al, 2009) for nearly 60 years by various types of annual trawl (e.g., Bolle et al, 2009;Tulp, Bolle, & Rijnsdorp, 2008), acoustic surveys (e.g., Couperus et al, 2016), and a daily fyke net catch program in the Marsdiep, at the border of the coastal North Sea and the western Wadden Sea (van der Meer, Witte, & van der Veer, 1995;van der Veer et al, 2015). Each sampling strategy has its own specific bias.…”

Shifts in trait-based and taxonomic macrofauna community structure along a 27-year time-series in the south-eastern North Sea

“…Significant long-term changes to taxonomic community variability in marine ecosystems have been documented worldwide [41–43], including in North Sea pelagic [44–46] and benthic [47–49] communities.…”

The dynamics of suspended particulate matter (SPM) and chlorophyll- a from intratidal to annual time scales in a coastal turbidity maximum

“…The majority of the northward transport of SPM along the coast, and also of nutrients, plankton, fish larvae and other juvenile marine fauna, may be concentrated in this small region. The TMZ is likely to control the distribution of macrobenthos, and the prey items of higher trophic levels such as predatory fish or birds (Van der Veer et al, 2015), by its high turbidity and nutrient levels. It is in this same zone that high densities of the benthic bivalve Ensis directus have been observed (Witbaard et al, 2015), which is a filter feeder thriving on suspended (phytoplankton) particles.…”
