Bait worms: a valuable and important fishery with implications for fisheries and conservation management

Bait is an integral part of coastal life, but is perceived as a low‐value resource as fisheries are data‐limited, locally focussed and largely unregulated even though the ecological impacts of collection are considerable. An empirical assessment of three UK‐based ragworm fisheries combined with an analysis of published literature has produced the first global assessment of polychaete bait fisheries. The five most expensive (retail price per kg) marine species sold on the global fisheries market are polychaetes (Glycera dibranchiata, Diopatra aciculata, Nereis (Alitta) virens, Arenicola defodiens and Marphysa sanguinea). We estimate that 1600 t of N. virens per annum (worth £52 million) are landed in the UK with approximately 121 000 tonnes of polychaetes collected globally valued at £5.9 billion. Using remote closed circuit television (CCTV) cameras to monitor collectors, activity at local sites is considerable with a mean of 3.14 collectors per tide (day and night) at one site and individuals digging for up to 3 h per tide, although intensity differed seasonally and between sites. Collectors removed on average 1.4 kg of N. virens per person per hour, walking a considerable distance across the intertidal sediment to reach areas that were usually already dug. The implications of these human activity and biomass removal levels are explored in the context of fisheries and conservation management. At local, regional and national scales, polychaete bait fisheries are highly valuable, extract significant biomass and have considerable impacts; therefore, they urgently require governance equivalent to other fisheries.

“…and lugworms (Arenicola cristata), are reported to naturally have higher DHA than EPA (Lytle et al 1990;Marsden et al 1992), whereas polychaetes that are avidly promoted for this use tend to have much higher EPA ratios and sometimes to extreme (e.g. Nereis diversicolor: Bischoff et al 2009;Glycera dibranchiata and N. viridens: Lytle et al 1990) (see Table 10). Nereis diversicolor in particular has been studied in this regard by several researchers.…”

“…Nereis diversicolor in particular has been studied in this regard by several researchers. It appears to have higher ratios of EPA under natural conditions, but reduced EPA relative to ARA and DHA when fed fish food or aquaculture sludge (GarciaAlonso et al 2008;Bischoff et al 2009). In the present study, levels of EPA and ARA in fish-meal-fed P. helleri were not significantly reduced, but their DHA content was significantly increased.…”

“…Bischoff et al . () cultured N. diversicolor in settlement tanks receiving wastewater from a sea bream recirculation system. Moreover, in 2010, Palmer assessed the ability of two intertidal polychaetes, Perinereis helleri and Perinereis nuntia , cultured in sand beds to remediate wastewater resulting from a prawn farm and produce harvestable polychaetes biomass without supplemental feeding using ‘polychaete‐assisted sand filters’.…”

The growing demand for fish products and the dwindling productivity of marine fish stocks due to the overexploitation of fisheries place the aquaculture industry as a key contributor to the global fish supply. The intensive development of aquaculture has raised a range of environmental concerns such as effluent discharge, excessive use of resources and dependence on commercial feed. In this context, the development of sustainable aquaculture systems is becoming the cornerstone for long-term aquaculture expansion, and to achieve environmental sustainability. Integrated multitrophic aquaculture (IMTA) is regarded as a suitable approach to limit aquaculture nutrients and organic matter outputs through biomitigation. The cocultured species are used as biofilters, and each level has its own independent commercial value, providing both economic and environmental sustainability. Here, environmental issues of aquaculture and the current status of IMTA are reviewed and its future prospects discussed. Also, the opportunities to expand this systems' complexity with increased added-value and trophic levels are introduced.
