Gillnets and stomach content metabarcoding - sharks and rays
<p>Gillnets are the world's most common net-based fishing gear, comprising walls of light mesh designed to entangle fish. Gillnets are often retrieved with holes in the netting, which means some animals escape or are depredated unseen, but with some mortality. To effectively manage fisheries around the world, information is required on not only the harvested and discarded mortalities, but also problematic interactions and mortalities caused by the fishing gear and especially those involving protected species. This study sought to assess a novel method for determining such interactions by sampling five adjacent pieces of netting around each of ten holes in two bather protection polyethylene gillnets for environmental DNA or 'eDNA'. Here we show that eDNA correctly identified all previously entangled-and-landed species. Also, eDNA from three uncaptured taxa were recorded: bull shark, <i>Carcharhinus leucas</i>, white shark, <i>Carcharodon carcharias</i> and dolphins (Delphindae), illustrating the potential to reveal previously cryptic gillnet interactions. We propose that as scientific methods evolve and autonomous real-time DNA surveillance becomes routine, eDNA testing of fishing gears and vessels could provide a novel, complementary fishery-monitoring tool.</p>
Data for: Size and abundance of stomach contents from Chatham Island lake smelt
<p><span>Sea level rise threatens ecosystem function in coastal lakes by increasing salinity and altering community composition. As mobile generalists, fish have considerable influence on the stability of a system by impacting trophic network structure. Understanding their diet across abiotic gradients, including salinity, can show key characteristics of their ecological role, and predator diet shifts may serve as warning signs of food web restructuring. Stomach contents analysis was used to look at the diet of <em>Retropinna retropinna</em> (common smelt) across shallow coastal lakes on Rēkohu (Chatham Island). Smelt stomachs from 10 lakes (seven freshwater; three salt-influenced) were analysed. Comparisons of salt-influenced and freshwater lakes showed shifts in composition, with reduced beta diversity with salinity.</span><span> Smelt</span><span> in freshwater lakes predominantly consumed herbivorous, omnivorous, or predatory insect larvae while diet in salt-influenced lakes was d</span><span>ominanted by crustacean shredders. The between lake taxonomic variation amongst salt-influenced lakes was lower than between freshwater lakes, suggesting homogenisation of smelt diet with salinity. Differences in composition and heterogeneity did not translate to consistent differences in total niche width or individual specialisation between freshwater and salt-influenced lakes. </span><span>Further development of knowledge on biological structure across</span><span> </span><span>salinity gradients is essential to understand </span><span>ecosystem function under future climate scenarios.</span></p>
