“…This is particularly important in areas where recreational fishing is a component of large tourism industries (Cisneros‐Montemayor et al ., ; Coleman et al ., ; Freire et al ., ). It is also crucial to recognize the social drivers of fishing behavior, as ‘bycatches’ may in fact contribute significantly to fisher incomes, and non‐target catches in industrial fisheries may still be sold informally, potentially to artisanal fishers (Nunoo et al ., ). Ultimately, any possible solution must involve re‐aligning economic incentives so that discarding is strongly discouraged or penalized (Arnason, ; Hall and Mainprize, ; Stanley et al ., ), in combination with a range of policies to foster and reward compliance with sustainable practices (Cisneros‐Montemayor et al ., ; Hosch, ; Stanley et al ., ).…”

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.

“…Ghana has historically been the major fishing country in the region, but the activity has been affected by variations in pelagic catches (Atta-Mills et al, 2004, Nunoo et al, 2014, Pauly and Zeller, 2015). Ghana, Nigeria and Sierra Leone were the major fishing countries in the Guinea Current LME during 2000–2010 with 31%, 16% and 14% of the pelagic catches (Pauly and Zeller, 2015).…”

HighlightsSatellite data were used to characterize the oceanography of the Gulf of Guinea.Ocean color CCI Chla offered unprecedented data coverage of the Gulf of Guinea.Chla was modeled as a function of SST, SLA, winds, currents, EKE, eddies and fronts.Chla was higher in upwelling conditions with cold SST, negative SLA, strong fronts.The impact of river outflow on Chla was significant mostly from Nigeria to Gabon.

“…As an approximation, linear interpolation was performed for filling data gaps in 1991-1992 because we did not find evidence of noticeable and short-lasting change in fishing operations at that period in available reports. Records of the Western and Central Pacific Fisheries Commission (WCPFC) were used as estimates of the annual catches in the Vanuatu EEZ since 2000 as reported in VFD national reports to the WCPFC (VFD, 2009(VFD, , 2015Nunoo et al, 2014). The reports cover the fishing activities in the Vanuatu EEZ and operations of the Vanuatu flag vessels that were active in the WCPFC and other regional fisheries management organization (RFMO) areas.…”

“…This industrial sector started in 1957 with the establishment of the South Pacific Fishing Company Limited (SPFC) in Palekula on Santo Island. It was dominated by longliners although some pole-and-line vessels and purse seiners sporadically fished in the area in the 1970s and 2000s, respectively (Nunoo et al, 2014;Pauly et al, in press). The fishery was mainly operated by foreign vessels from Japan, Korea, Taiwan, China, and Fiji under joint-venture or bilateral fishing agreements.…”

An Improved Reconstruction of Total Marine Fisheries Catches for the New Hebrides and the Republic of Vanuatu, 1950–2014

For many small island nations, fisheries provide residents with both food security and economic stability. However, in order to create effective and sustainable fisheries policies and management that will ensure a growing population can prosper, policy makers need to know what is being fished and how much is fished. Vanuatu, the smallest country in Melanesia, has a declared and claimed Exclusive Economic Zone (EEZ) of over 820,000 km 2 and fisheries resources play a large part in the food security and economic stability of this country. This reconstruction of the total marine fisheries catch of Vanuatu for 1950-2014 faced major data gaps. It showed that the reconstructed total catches of nearly 1.4 million tonnes (metric tons) 40% higher than the 977,997 tonnes reported by the Food and Agriculture Organization (FAO) on behalf of Vanuatu for the same period. However, if large-scale industrial catches are excluded, the reconstructed small-scale fisheries catches (∼270,000 tonnes) were over 200% higher than the 114,862 tonnes of reported catch that were assumed to represent the small-scale sector in FAO data. Subsistence catches made up almost 93% of small-scale catches, followed by artisanal and recreational catches with ∼7 and <1%, respectively. By continuously improving the fisheries data of Vanuatu for both the past and the present, policy makers, stakeholders, and fishers can make better decisions that will maintain the benefits of marine fishery resources.
