“…In the Lower Mekong Delta, there is a 221% discrepancy between the official yield figures of 1.2 million tonnes and estimated consumption of 2.6 million tonnes (Hortle 2007). While yields from small-scale artisanal fishing (e.g., subsistence, local trade) do not often enter a market economy and consequently are not often recorded (Bartley et al 2015), they represent the primary animal protein source for many of the rural poor and are crucial to global food security.…”

“…More than 60 million people in low income countries rely upon inland fisheries as a source of livelihood and women represent over half the individuals in inland fisheries supply chains (FAO 2014b). While still a large number, this is widely accepted to be an underestimate given the difficulties with reporting in the sector (Bartley et al 2015). Inland fish and fisheries provide cultural and recreational services and contributions to human health and well-being.…”

“…In discussions of global capture fisheries, inland fisheries are often overwhelmed by marine fisheries because of the sheer magnitude of reported marine catches (marine catches are approximately seven times higher than inland catches; FAO 2014b). However, several lines of evidence (e.g., consumption studies) suggest that inland fisheries harvest is often unrecorded or drastically underreported, particularly with reference to the prevalence of small-scale or artisanal fishing (i.e., subsistence and local trade) in inland waters (Hortle 2007;FAO 2010aFAO , 2012Welcomme et al 2010;Bartley et al 2015). In addition to harvest, inland aquaculture has experienced considerable growth over the past decade.…”

Though reported capture fisheries are dominated by marine production, inland fish and fisheries make substantial contributions to meeting the challenges faced by individuals, society, and the environment in a changing global landscape. Inland capture fisheries and aquaculture contribute over 40% to the world's reported finfish production from less than 0.01% of the total volume of water on earth. These fisheries provide food for billions and livelihoods for millions of people worldwide. Herein, using supporting evidence from the literature, we review 10 reasons why inland fish and fisheries are important to the individual (food security, economic security, empowerment), to society (cultural services, recreational services, human health and well-being, knowledge transfer and capacity building), and to the environment (ecosystem function and biodiversity, as aquatic "canaries", the "green food" movement). However, the current limitations to valuing the services provided by inland fish and fisheries make comparison with other water resource users extremely difficult. This list can serve to demonstrate the importance of inland fish and fisheries, a necessary first step to better incorporating them into agriculture, land-use, and water resource planning, where they are currently often underappreciated or ignored.Key words: food security, freshwater ecosystems, importance of fish, inland fisheries.Résumé : Bien que la capture de poissons rapportée par les pêcheries soit dominée par la production marine, les poissons et les pêcheries de l'intérieur des terres apportent des contributions substantielles pour rencontrer les défis rencontrés par les individus, les sociétés et l'environnement dans un paysage en changement global. Les captures des pêcheries de l'intérieur et l'aquaculture contribuent à la hauteur de 40 % à la production mondiale rapportée pour les poissons à nageoires, à partir de moins de 0,01 % du volume total de l'eau sur terre. Ces pêcheries fournissent de la nourriture pour des milliards et un moyen de subsistance pour des millions de gens, partout au monde. Dans cette revue, en utilisant des preuves venant de la littérature, les auteurs examinent 10 raisons pour lesquelles, les pêcheries et les poissons de l'intérieur sont importants pour les individus (sécurité alimentaire, sécurité économique, l'autonomisation), pour la société (services culturels, services récréatifs, santé humaine et bien-être, transfert de connaissances et capacité à construire) et pour l'environnement (fonction écosystémique et biodiversité, comme « canaris » aquatiques, pour le mouvement « aliments verts »). Cependant, les limitations actuelles pour évaluer les services fournis par les poissons et les pêcheries intérieures rendent les comparaisons avec les autres utilisateurs de la ressource en eau extrêmement difficile. Cette liste peut servir à démontrer l'importance des poissons et des pêcheries de l'intérieur, une première étape essentielle pour mieux les incorporer avec l'agriculture, l'utilisation du territoire e...

“…Targeted analyses have been conducted on certain river systems such as the Mekong [10,11], or regions such as Southeast Asia [12] but the approaches (e.g., consumption surveys, intensive field sampling) would not be feasible at a global scale due to the cost and effort involved [13]. Most river fisheries are highly diffuse and small-scale in nature and in areas lacking necessary infrastructure for regular reporting, so the data collection that is occurring is generally not systematically distributed, but instead tend to be focused in the most developed countries [14]. Understanding the catch trends and predictions of river fisheries harvests is critical for the future of stakeholders who depend on these systems for food and livelihoods, but these fisheries harvests have not yet been quantitatively assessed at the global level in the ways that marine fisheries have been [15,16].…”

Background: Although surface freshwater comprises < 0.01% of the total water volume of earth, freshwater inland capture fisheries and aquaculture represent 40% of the global reported finfish harvest. While the social, economic, and ecological importance of inland fish and fisheries is difficult to overstate, they are often undervalued and underappreciated. Accurate information about these highly dispersed fisheries is inherently difficult to acquire, often unreported, and not collected in a standardized format globally. A standardized river fishery database is needed for managing aquatic systems as well as for defining relevant development policies. Here, we describe our methodology to search, identify, and describe available river fisheries information to create a harmonized global database of river fisheries harvest. This database will provide the first global database of spatially and temporally explicit river fisheries data. The database can be used to identify locations, hotspots of data collection, and gaps in existing knowledge and will be especially important to inform studies and management at larger spatial scales (i.e., watershed, regional, or global scales). This database will also be critical for developing fish biomass models for rivers, which can provide managers with information critical for decision-making, such as improved valuation methods for river fish and fisheries.Methods: This systematic map protocol describes the methodology to search, identify, and describe available information on river fish and fisheries across the globe. We define river fisheries as "both capture and aquaculture of river finfish species for food, income, or recreation". River fish species are those finfish that live part, or all of their lives in rivers. The searches will be conducted for the period from 1950 to present using bibliographic databases and grey literature sources. To identify relevant evidence, pre-defined inclusion and exclusion criteria will be used to screen articles at title, abstract, and full text. A searchable database containing extracted meta-data from relevant included studies will be developed and presented as a geodatabase. The final systematic map will consist of a descriptive narrative report of the distribution and content of river fish literature including a geodatabase of available information.

“…It is composed primarily of small-scale fishermen and provides employment for approximately 61 million people, 50% of whom are women (Bartley et al, 2015). Although inland waters commercial fisheries have declined throughout northern and eastern Europe, they still have some significance in several eastern European countries (Cowx, 2015).…”

The official data on recreational and artisanal fisheries in Croatia and Hungary were analysed. The data from Croatia relates to the entire Croatian section of the Danube River and to the section of the Sava River along the border with Bosnia and Herzegovina. The data from Hungary covers 60 km of the Danube River north of the Croatian border. Absolute catches in kilograms, as well as CPUE (kg per fisherman per year) by both groups in all three river sections varied from year to year without dramatic changes. Fishing with nets, artisanal fishermen differ from the anglers in two major ways: they are less selective and they catch bigger specimens. According to the official data, the existing ratio between recreational and artisanal fishermen in these three river sections does not negatively affect each other's or overall fishing. Therefore, a conclusion can be drawn that medium-intensive artisanal fisheries qualify to co-exist with recreational fisheries. How to CiteTreer, T., Kubatov, I.
