Determism of Fish Assemblage Structure in Neotropical Floodplain Lakes: Influence of Internal and Landscape Lake Conditions  

Determism of Fish Assemblage Structure in Neotropical Floodplain Lakes: Influence of Internal and Landscape Lake Conditions

In the neotropics, seasonal flooding renders the floodplain an open system in which many fish species can disperse freely.Consequently, it has been suggested that fish assemblage structure in floodplain lakes is largely stochastic.

Dependence of Tropical River Fisheries on Flow  

Dependence of Tropical River Fisheries on Flow

Much work has been done on the flow requirements for maintenance of fish populations and fisheries in temperate rivers but few equivalent studies are available upon which to base criteria for the management of water regimes for fishes and fisheries in large river systems, particularly in the tropics.

The Flood Pulse Concept: New Aspects, Approaches, and Applications   An Update  

The Flood Pulse Concept: New Aspects, Approaches, and Applications - An Update

The flood pulse concept (FPC), published in 1989, was based on the scientific experience of the authors and published data worldwide.Since then, knowledge on floodplains has increased considerably, creating a large database for testing the predictions of the concept.

An Overview of Legal Issues and Broad Legislative Considerations for Community Based Fisheries Management  

An Overview of Legal Issues and Broad Legislative Considerations for Community-Based Fisheries Management

The fertile literature on community-based natural resource management (CBNRM) in general and in the fisheries sector in particular, shows that the implementation of such approaches to management will have a broad range of implications including policy, technical, institutional and legal implications.

The Plata River Basin: International Basin Development and Riverine Fisheries  

The Plata River Basin: International Basin Development and Riverine Fisheries

Environmental changes in large river basins are subject to forces external to the water and to biological issues.Before 1960, the Plata River Basin was almost undeveloped.The regulation of the Parana for hydroelectricity has been increasing since the early 1970s.
