Which future scenario is more sustainable?Intro Literature review  Framework  Case study  Uncertainty  Conclusions

• Scenario 2 (+DHC) maximises socio‐economic performance. It seems to be the best alternative among the three scenarios modelled

• Scenario 3 (Diversification) improves ecosystem health but decreases socio‐economic performance. 

• Scenario 3 seems less preferable than Scenario 1 (Status quo) and• Scenario 3 seems less preferable than Scenario 1 (Status quo) and Scenario 2, despite some ecological and environmental improvements

Any future scenario modelling featuring reduction of anchovetamortality should feature sensitivity analyses to estimate the optimal level of reduction according to the response of all species in the ecosystem, including seabirds and mammals, and their usefulness and potential use (e.g. tourism)

Ecological indicators: inverse fishing pressureIntro Literature review  Framework Case study  Uncertainty  Conclusions

“1/(landings/biomass)” measures the inverse level of exploitation or total fishing pressure on an ecosystem. This indicator is considered as a measure of resource 

i l b i fl h f h i d i d di d fi hipotential because it reflects the part of the community production dedicated to fishing. It is more commonly expressed as landings/biomass (as a proxy for exploitation rate), but it was inverted here so that it should decrease under increasing fishing pressure, hence varying theoretically in the same direction as the other indicators in the selected y g ysuite. Notwithstanding, care needs to be taken in interpreting trends in this indicator because variations in total biomass and catch are not only the result of fishing (Bundy et al., 2010). Further, it is influenced by changes over time in the selectivity of fishing gear and in the species targeted b fishing sectors as ell as b inconsistencies in reportedand in the species targeted by fishing sectors, as well as by inconsistencies in reported catches (Bundy et al., 2010). 

Retained species (landings): these are species caught in fishing operations, although not necessarily targeted by a fishery (i.e. including by‐catch species), and which are retained because they are of commercial interest, i.e. not discarded once caught, although this does not imply that sometimes certain size classes of those species may not be discarded A non‐retained species is considered to be one that would never be retained

Ecological indicators: TL of landingsIntro Literature review  Framework Case study  Uncertainty  Conclusions

“TL of landings” measures the weighted mean TL of species exploited by the fishery, representing the trophic position of the whole catch, and is expected to decrease in response to fishing because fisheries tend to target species at higher TLs first (Paulyresponse to fishing, because fisheries tend to target species at higher TLs first (Paulyet al., 1998). Initially, catches increase as the foodweb is fished down and because lower TLs are ecologically less expensive (production is greater at lower TL and there is less loss of productivity by trophic transfer up the foodweb), catches may ultimately stabilize or decline (Pauly et al., 1998). Fishing can change the structure of marine foodwebs by reducing the mean TL and potentially also ecosystem functioning by shortening the length of food chains and releasing predation on low‐trophic‐level organisms TL is considered to be a measure of ecosystem structuretrophic level organisms. TL is considered to be a measure of ecosystem structure and functioning and is used to measure state and trend.

TL can vary with fish age because fish are life‐history‐dependent omnivores. By considering TL of landings (vs. TL of the community), however, we focus on the recruited/adult stages of the populations to which the species TL estimates better correspond

Ecological indicators: Proportion of predatory fishIntro Literature review  Framework Case study  Uncertainty  Conclusions

“Proportion of predatory fish” in the biomass is a measure of the di i f fi h i h i d fl h i l ff f

(back)

diversity of fish in the community and reflects the potential effects of fishing on the functioning of marine foodwebs. The resilience of predator species is particularly threatened by intense exploitation (Hutchings 2000; Christensen et al 2003; Myers and Worm 2003)(Hutchings, 2000; Christensen et al., 2003; Myers and Worm, 2003), but their role in the ecosystem is essential because they act as dampeners of the whole foodweb (Sala, 2006), and their depletion can lead to trophic cascades (Frank et al., 2005, 2006; Daskalov et al.,can lead to trophic cascades (Frank et al., 2005, 2006; Daskalov et al., 2007). Restoring the declining abundance of predator functional groups should be a target of EAF implementation (Daskalov, 2008). The indicator is used to measure state and trend. For its calculation here, predatory fish were considered to include all fish species surveyed that are piscivorous or feed on invertebrates >2 cm.

Uncertainty managementIntro Literature review  Framework  Case study  Uncertainty Conclusions

Issues category

Description Treatment

Data issues associated to cut‐off criteria and multiple data sources.  The use of weighted averages to harmonise multiple data sources may reduce deviations in results due to uncertainty.Sensitivity analyses of input data should be applied to various ranges of key contributors to environmental impacts (e.g. fuel use). Both treatments were applied

Toxicity calculation issues arise from diverse implementations featured in existing toxicity methods.

Comparing various toxicity methods, for instance ReCiPe/USES‐LCA vs. USEtox(scientific consensus method), would clarify toxicity contribution of studied systems. Relevant LCIA methods are described in Appendix C: A comparison of 

LCA related 

current Life Cycle Impact Assessment methods. This treatments was applied

Allocation issues occur in multi‐species fisheries and multi‐function fishfood processes, as extensively discussed in fishfood LCA literature.

Contrasting diverse allocation methods, as practiced in literature, would highlight sensitivity of results to allocation. A specific approach for allocation in fisheries LCA studies is described in section 2.4.1. For fishfood co products energy based allocation was practiced and other

issues*  For fishfood co‐products, energy‐based allocation was practiced, and other allocation criteria for other situations

Impact assessment issues due to the fact that fishfood‐specific categories are not implemented in LCIA methods, namely species removal and seafloor damage (for fisheries) and biotic resource use (for fishfood products in general).

Calculation of those impact categories contributes to more complete and relevant LCA studies. Moreover, additional impact categories and LCIA methods should be included, when relevant, to offer a more multi‐criteria comparison (i.e. BRU including discards, complemented with energy efficiency and ( p g ) ( g p gy ynutritional indicators). A variety of fishfood‐specific impact categories were computed

Differences in system boundary setting and cut‐off criteria among LCA studies make difficult the nesting of studies to cover large segments of a fishfood supply chain (e.g. integration of studies on 

System boundaries and cut‐off criteria must be clearly described and justified. All life cycle stages of the system under study should be included, despite any perceived negligibility in contribution to environmental impacts (e.g. in

fisheries, both construction and end of life of vessels should be included).Whole cradle to gate LCAs were modelled, as well as distribution/retailing for final products
