Overview

An ever-growing number of small, medium and large reservoirs are being built in the world for irrigation or hydro-power purposes. While some fishing activities take place on these water-bodies, the productivity of their fisheries is in many cases far below the identified biological potential. Yet, fisheries and their associated activities (fish processing and fish trading) have been recognized to play a critical role in terms of food security and economic development.

Reservoirs are only semi-natural ecosystems, usually being the result of humans having transformed a river into a lake, with a sometimes poorly adapted and consequently highly dynamic aquatic fauna. The productivity from reservoir fisheries can be increased through a number of approaches combining better harvesting strategies, carefully adapted stock enhancements, and aquaculture activities. To achieve this untapped potential while securing ecosystem services such as water quality and biodiversity, a holistic approach and improved understanding involving both bilogical principles and stakeholder participation is necessary. The natural biophysical constraints of the reservoirs define the ecological production processes and the socio-economic settings shape the human production enhancement possibilities. By synthesizing these mechanisms into general principles and predictive indicators it should be possible to provide various options and scenarios for improved productivity that can be adapted to the local cultural and institutional settings. The main objective of this 3.5 year CPWF project was to increase the productivity of reservoir fisheries and provide sustainable livelihoods to the rural poor through a series of interventions in tropical reservoirs.

The main project activities focused on two reservoirs in the Indo-Gangetic basin (Dahob in Madhya Pradesh, and Pahuj in Uttar Pradesh, both in India), the Lake Nasser in Egypt as part as the Nile basin, and the Volta Lake in Ghana as part as the Volta basin. For each of those sites the specific objectives of the project were:-          Objective 1: To identify, develop, and test in collaboration with the main stakeholders, fisheries enhancement tools and strategies leading to increased fish productivity and better community livelihood prospects;-          Objective 2: To improve the understanding about the overall human contexts of those reservoirs and identify potential socio-institutional obstacles to the adoption of increased fishery productivity innovations;-          Objective 3: To facilitate the implementation of these fisheries productivity interventions by improving the stakeholders’ management skills and fostering their institutional capacities;In addition to those objectives, the project encompassed an initial data inventory from a wide variety of tropical reservoirs within the three basins, and the detailed assessment of the selected reservoirs, including market evaluation and post-capture improvements.
