“…In addition, required reduction in biomass and expected ecological improvements to aquatic ecosystems can take a number of years to eventuate following exclusion or removal (e.g., Chumchall et al., 2005; Loughheed et al., 1998) and may be unmeasurable over shorter timescales especially where underlying catchment or hydrological issues are unaddressed (Tempero et al., 2019). Consequently, innovative self‐funded, or cost‐recovering, programmes have the potential to provide long‐term solutions, especially where captured IAF biomass can be converted into products to support other environmental initiatives, generating an income stream or cost savings to organizations that support sustained localized removal efforts (e.g., David et al., 2018).…”

“…Strategic deployment of connectivity filters at the floodplain scale, coupled with reinstatement of migration cues for native galaxiids at key times, offers the opportunity to enhance resilience of native fish assemblages to flood control infrastructure and IAF. Additionally, active manipulation of these filters provides opportunities to limit IAF access to spawning habitats and even harvest IAF after they have been trapped or stranded (David et al., 2018). Control of non‐migratory littoral species such as Gambusia by regulating connectivity can be more challenging, as they are able to rapidly colonize and recruit in waterbodies, often reaching very high densities over short periods, especially amongst littoral vegetation in lakes (Pingram, 2005) and other permanent floodplain waterbodies utilized by native fish (Wu et al., 2013).…”

“…Although it is quite difficult to change market forces, there is a need to first increase awareness among dealers and buyers that diversification strategies are a powerful way to buffer risk. Specifically, management strategies should aim to encourage the seasonal supply of multiple species and the production of high‐value or new value‐added fishery products, and to create new opportunities to use low‐value or unutilized species (David, Özkundakci, Pingram, Bergin, & Bergin, ). An example of the latter involves invasive species.…”

Catch diversification provides multiple benefits in inland fisheries

Diversification of fisheries and agroecosystems can increase and stabilize production and revenue, despite unpredictable changes in ecosystems and markets. Recent work suggests that diversification can provide multiple benefits simultaneously, but empirical evidence of relationships between catch or crop diversification and the provision of multiple benefits is scarce. The effect of diversification on multiple benefits may vary temporally and among systems. Using long‐term (11–54 years) capture fishery statistics from five Japanese lakes, we examined whether catch diversity increased multiple benefits, including revenue, nitrogen and phosphorus removal, and seasonal commercial species diversity. We also assessed whether catch species diversity increased the stability of each benefit via a portfolio effect (PE). Our study revealed positive relationships between catch diversity and the bundle of benefits (the mean of all normalized benefits; i.e., the provisioning of multiple benefits) in all five lakes, even after controlling for the total catch. The effects of catch diversity on individual benefits were positive or insignificant and differed among the study lakes. These differences were likely caused by the range and variation of functional characteristics among catch species. The influence of the annual mean price on revenue suggested that market forces did have an effect. We also found that aggregated revenue as well as N and P removal were 1.6–2.1 times (four lakes), 1.5–2.2 times (four lakes), and 1.4–2.2 times (all five lakes) more stable, respectively, than would be expected if only a single species were harvested. This greater stability suggests that maintaining catch species diversity may increase the stability of multiple benefits through PEs. Synthesis and applications. Our analysis suggests that catch diversification has great potential to increase the magnitude and stability of multiple benefits. Although total catch alone was sufficient to provide multiple benefits, a goal of maximization with specialization may decrease stability and deplete resources. Under fluctuating environmental and economic conditions, diversification strategies promise to be a potential management option for achieving resilient and sustainable inland fisheries.

“…Many lakes in New Zealand have been under increasing anthropogenic pressures such as the intensification of land use, urbanisation and the introduction of invasive species. Declining water quality, biodiversity loss, and cyanobacteria blooms are now observed frequently (Ministry for the Environment and StatsNZ 2017; David et al 2018). In this special issue, attention is directed towards the implications of those pressures for lake ecosystem dynamics, under the unifying theme of 'Lake Resilience'.…”
