Among users of the water resource are fishes and fishermen. Given the importance of fisheries in the Lower Mekong River Basin, water management schemes must take the fish resource into consideration. Therefore hydrological modelling must encompass hydrobiological issues of critical importance for fisheries. This presentation is an overview of the practical aspects of modelling the relationship between water flow and fish production. The different ways of addressing this issue are listed, together with their corresponding data requirements.
To enable an understanding of the dynamics of fishing overcapacity, conflicts and security issues in the Philippines, a case study is drawn of the fisheries conflicts arising from zoning regulations. A semi-structured questionnaire was used within an interview context to gather information on the study variables. These were complemented by key respondents interviews and focus group discussions.
This report from WorldFish is divided into two sections, with annexes. Section One contains the workshop report, including the workshop results and outputs. Section Two contains summary papers of the workshop presentations with a record of relevant points of discussion. The annexes contain additional information such as the participant list, detailed findings and speeches.
This paper is arranged in two parts. The first summarizes technical issues surrounding such assessments, briefly reviews the water requirements of river fish and fisheries, and examines some of the ways for predicting these requirements. The second part examines practical experiences in southern Africa by outlining ten general principles that can guide the environmental flow assessment process.
This review showed that the contributions from inland fisheries and aquaculture in economic and social development are undervalued and warrant integrated water management approach to address the various challenges presented effectively.
This article presents the methodological aspects of the development of a decision support system (DSS) based on Bayesian networks and aiming at assisting in the management of water-dependent resources (rice, fish, shrimp and crab). The principles of Bayesian networks are introduced, then the steps of model development are detailed and illustrated by the BayFish model being developed in the inland coastal zone of Bac Lieu Province (Vietnam). The particular feature of this DSS is that it is based on the contribution of local stakeholders.
An experiment to rear carp seed was conducted in Tamil Nadu, India during October 2001 to April 2002 as a part of an ambitious programme aimed at standardization of pen fish rearing technology for production of stocking material of desired size at a lower cost. The experiment used six pens erected using locally available materials in the exposed marginal area of an existing reservoir.
For the people of Africa. Asia and Latin America the fisheries of inland lakes, rivers and other freshwater ecosystems provide an important source of food and income, and for many these are the principal source of animal protein.
The general goals of the research of this paper are 1. To develop a broad framework for addressing approaches for reducing overcapacity in the fisheries of Southeast Asia; and 2. To examine where conflicts may arise and to provide plans to ameliorate these conflicts and its role in reducing conflicts and enhancing national and regional security. The research will attempt to meet these broad goals by pursuing the following specific objectives: 1. To describe the socio-economic conditions of fishers in selected areas around the Visayan Sea. 2.
