The role of inland fisheries in livelihoods, food security and sustainable development is often overshadowed by the higher profile interest in ocean issues. Whilst inland fisheries' catch and contribution to global nutrition, food security and the economy, are less than that of marine fisheries, global‐level comparisons of fish production obscure considerable livelihood impacts in certain countries and sub‐national areas. To highlight these contributions, this paper synthesizes recent data and innovative approaches for assessing such livelihood contributions and their importance in countries with limited access to ocean resources and aquaculture. Inland fisheries are crucial for many socially, economically and nutritionally vulnerable groups of people around the world, but the challenges in monitoring inland fisheries preclude a complete understanding of the magnitude of their contributions. This situation is rapidly improving with increasing recognition of inland fisheries in development discourses, which has also encouraged research to enhance knowledge on the importance of inland fisheries. We review this work, including collated information published in a recent Food and Agriculture Organization report, to provide an up to date characterization of the state of knowledge on the role of inland fisheries.

“…High dependence for jobs was more common in countries with sizeable small-scale fisheries (Teh & Sumaila, 2013). Future analyses could assess fishing effort by foreign vessel fleets, the EEZs targeted by those fleets (Pauly & Zeller, 2016), export data on volume (FAO, 2014), and fish price databases (Tai, Cashion, Lam, Swartz, & Sumaila, 2017) to better understand how international harvesting patterns and trade may affect economic dependence.…”

Many human populations are dependent on marine ecosystems for a range of benefits, but we understand little about where and to what degree people rely on these ecosystem services. We created a new conceptual model to map the degree of human dependence on marine ecosystems based on the magnitude of the benefit, susceptibility of people to a loss of that benefit, and the availability of alternatives. We focused on mapping nutritional, economic, and coastal protection dependence, but our model is repeatable, scalable, applicable to other ecosystems, and designed to incorporate additional services and data. Here we show that dependence was highest for Pacific and Indian Ocean island nations and several West African countries. More than 775 million people live in areas with relatively high dependence scores. By identifying where and how people are dependent on marine ecosystems, our framework can be used to design more effective large‐scale management and policy interventions.

“…The authors estimated missing ex‐vessel prices using the country‐product‐dummy model, which uses within‐year prices for estimation to address year‐specific differences in market prices of commodities (Summers, ). Reported price input data are then linked by taxonomic classification based on a step‐wise schematic of broader taxonomic classifications (for a detailed description see Swartz et al ., ; Tai et al ., in revision). Available yearly data on country‐specific prices of course would be the first best‐option, yet the price database uses a robust interpolation algorithm to determine ex‐vessel prices, and includes several controls to avoid under‐ or overestimations of prices.…”

“…This study uses available fish ex-vessel prices (Sumaila et al, 2007;Tai et al, 2017) to assign (market and shadow) economic values to unreported catches using data from Panama's fisheries (Harper et al, 2014). Potential values of unreported catches were broken down by source and sector to identify when economic opportunities were lost or undervalued.…”

Fisheries catches are known to be widely underreported, and much of their value flows in informal markets. Goods and services that are not directly sold in a market also have a corresponding economic value, here termed ‘shadow value’, which can apply to discarded fish—or those that are consumed but not sold (e.g., subsistence catches). Here, we estimate the monetary value of fisheries catches in Panama that are landed but not reported, or that are discarded at sea; this includes catches from artisanal and industrial fleets, as well as recreational and subsistence fisheries. Based on available data, we estimate that the market and shadow value of unreported catches in Panama in 2010 was around US$92 million, equal to approximately 43% of the total reported landed value. In the case of discarded fish, the shadow value represents the potential but entirely unrealized economic benefit of landing such fish; in the case of unreported landings, unreported market value represents only the first link in the potentially sophisticated informal seafood economy. One must be careful in considering these results for policy. It is possible that, rather than seeking to capture these ‘lost’ benefits, fish that are discarded or unreported should not have been caught at all, for example, if they are juveniles or of threatened species; conversely, unreported subsistence catches are crucial for food security throughout the world. These results help contextualize the scale of unreported fisheries in economic terms, and can inform subsequent policies and strategies to ensure social, ecological, and economic sustainability.
