E-book Threats to Our Ocean Heritage: Bottom Trawling

Trawling has been recognised as a profoundly damaging practice with lasting nega-tive consequences on seabed ecology and marine life since its first mention in a 1376 parliamentary petition. Mobile fishing gear (including any dredge, trawl, or similar device) is used to tow or push a net with a boat to catch fish. Bottom trawl-ing, in particular, grew from a need to keep up with declining fish stocks and devel-oped further with technological changes and increased demands, though it created ‘anger and resentment’ within the fishing communities (Bolster, 2012, p. 236). All three trawling revolutions—invention, mechanisation, and later deep-water expan-sion—have been met with controversy and pushback by the public and environmen-talists alike (Roberts, 2008).There is no doubt that trawling has decimated fish stocks globally which has brought hardship on fishing communities. Today’s boats must work an estimated 17 times harder than in the past because there are literally fewer fish in the sea (Roberts, 2012; Thurstan et al., 2010). Every year trawlers plough areas of the seabed roughly equal to half of the world’s continental shelves and convert the rich seafloor below into a bleak landscape of flat nothing (Watling & Norse, 1998). With one pass by a trawler, boulders can be displaced, large epifaunal invertebrates removed and dam-aged, and sediment re-suspended (Freese et al., 1999). Yet little has been done to seriously limit the practice and protect the underwater landscape.Crucially, archaeological impacts and data are also missing from biological reports and published articles on the practice. Trawling also has dramatic impacts on maritime archaeology sites, though these effects are less well known. The sea-floor landscape includes historical information and sites of cultural significance. Bottom trawling does not just destroy the physical fish habitats—important ship-wrecks and artefacts are lost too and ostensibly have been since the inception of trawling. Trawling gear damages wrecks when their nets snag and are tangled with shipwreck structures, often destroying components, and the trawl doors and chains can destroy and scatter artefacts and vessel components (Brennan, 2016). Archaeologists have recently begun raising awareness about the impact of trawling on their sites, and more work is needed.
