“…[ 2 ] and de Graaf [ 3 ] reported positive correlations of yield with flooding indices occurring earlier in the same year, from the Tonlé Sap bag fishery in the Mekong and from a Bangladesh floodplain fishery, respectively. Welcomme [ 4 ] reported greatest correlations from varying proportions of a flooding index for one and two preceding years among three African floodplains, but the index was correlated negatively to a drawdown index.

Response of Prochilodus nigricans to flood pulse variation in the central Amazon

et al. 2018

The influence of the flood pulse on fish populations has been posited, but infrequently tested or quantified. Here, we tested the effect of habitat on population size, using Prochilodus nigricans as a case study species. Floodplain habitat was based on the littoral zone area occupied by P. nigricans to feed. The magnitude of this habitat in each hydrological year, the moving littoral (ML), was expressed as the sum of daily littoral areas during the advancing flood pulse, using satellite-based passive microwave data. Annual population size was estimated by age class, using a dynamic age-structured model (MULTIFAN-CL) based on catches, effort and fish length frequencies from the Manaus-based fishery over 12.75 years. The principal null hypothesis was that the ML, using three lag times, had no effect on population size of a single age class of P. nigricans. The population size at 29 months of age was positively related (p = 0.00030) to floodplain habitat (ML) earlier in the same year, when the fish were 21–27 months old. The result implies a density-dependent relationship for the population with respect to its feeding habitat. Potential mechanisms governed by flood pulse variation and habitat quality for this and other species using floodplain habitats are discussed.

“…Conversely, a monocentric administration would have a centralized organization overseeing the entire basin with an apex authority that coordinates collection of data and resource allocation over a hierarchy of subbasins (Molle, 2009), and seeks to manage basin-wide fisheries with broad-scale standards and procedures. Successful basin management of water resources (Lankford & Hepworth, 2010) and their fisheries (Welcomme, 2016) (Lehner et al, 2011) the and participation (Chen, Duan, Liu, & Shi, 2004;Zhou, 2006), resulting in ineffectual monocentrism due to weak polycentrism.…”

“…Conversely, a monocentric administration would have a centralized organization overseeing the entire basin with an apex authority that coordinates collection of data and resource allocation over a hierarchy of sub‐basins (Molle, 2009), and seeks to manage basin‐wide fisheries with broad‐scale standards and procedures. Successful basin management of water resources (Lankford & Hepworth, 2010) and their fisheries (Welcomme, 2016) require a sensible balance between polycentrism and monocentrism, as a monocentric basin‐wide vision may be needed for polycentric local management to function. This principle is implemented by the North American Waterfowl Management Plan and may apply to reservoir fisheries.…”

A bird's‐eye view of reservoirs in the Mississippi Basin tips a need for large‐scale coordination

et al. 2020

Reservoirs are mostly managed at local scales as spatially independent units. A basin‐scale perspective may increase awareness at a broader scope and generate insight not evident at local scales. We examined the array of reservoir attributes and fisheries in the Mississippi Basin to identify management opportunities. The basin is the third largest in the world and includes over 1,700 reservoirs >100 ha, the most of any river basin. Our bird's‐eye view shows a piecemeal approach where reservoirs are mostly administered at the local level. Basin‐wide or catchment coordination to holistically address problems that recur across the basin is mostly lacking. A basin‐wide coordination arrangement could facilitate various facets of reservoir management. We reviewed governance arrangements in major river basins across the globe and concluded that the basin‐wide administrative layer we encourage for the Mississippi Basin may already exist in some basins but may not be directly applicable everywhere.

“…In South America, the largest fluvial continent in the world, deterioration of floodplains, agricultural and cattle development, fishing pressure, water diversion, pollution and particularly damming are challenges to the maintenance of fisheries in a sustainable state (Barletta et al 2010). Conflicts in freshwater fisheries are commonplace, as there are different objectives and priorities among user groups even in the same fishery or basin (Welcomme 2016). Most fluvial fisheries still exhibit low management performance or are still managed under a conventional approach.…”

Most small‐scale fisheries of large floodplain rivers are still managed under conventional top‐down regulations that limit the application of an ecosystem approach to fisheries (EAF) due to inappropriate legal frameworks. Using the Parana–Paraguay River fisheries (Argentina) as an example, this study examines the extent to which existing provincial legislations can be prepared for the adoption of an EAF. An Ecosystem Fishing Legal Approach (EFLA) framework is proposed based on different criteria across an environmental–ecological, fishing, social, economic and institutional template. Policy Component Scores (PCS) and an Integrated Policy Legal Index (IPLI) were applied to assess the degree of compliance by current provincial legislations to EAF implementation. Cluster analysis was used to recognise the potential for articulating a legal framework at a basin scale. The EFLA framework, which provided an accurate picture of how provinces were poorly prepared to adopt an EAF for the Paraguay–Parana fisheries, and represents a suitable tool that can be adapted and extended to other basins around the world.
