Perspectives on culture-based fisheries developments in Asia

Author(s): De Silva, S., Ingram, B.A., Wilkinson, S. | Published: 12/5/2015 | 4671 views

This book is the proceedings of the “Regional Consultation on Culture-Based Fisheries Development in Asia”, held in Siem Reap, Cambodia, 21-23rd of October 2014, under the auspices of the Australian Centre for International Agricultural Research (ACIAR), the Mekong River Commission (MRC) and the Network of Aquaculture Centres in Asia-Pacific (NACA). The consultation was jointly organised by NACA and the Fisheries Administration of the Royal Government of Cambodia.

Food and nutritional security remains problematic in many developing countries.  There are many initiatives underway which are designed to increase food supply, employment and income opportunities, most of which require considerable capital inputs (for instance cropping, livestock production and aquaculture). Often overlooked, are the opportunities to produce more food from the natural productive ecology of lakes and forests. Culture-based fisheries are one example of a relatively simple and low cost technology which can deliver nutritional and economic benefits to communities which often have few livelihood options.

Culture-based fisheries are based in lakes and reservoirs, where fish populations are supplemented by hatchery-produced fingerlings. The stocked fish may breed naturally in the lakes, or they may be species which are desirable but which do not breed in the still-water environments. Fish growth is driven by the natural productivity of the water bodies. Generally, local communities have ownership of the fish, with the benefits shared or used for communal purposes. However, there are other options for management and ownership depending on local needs, cultural arrangements and other uses of the water.

Research and development of culture-based fisheries has been a major endeavour for NACA and ACIAR since the mid-1990s. This has involved projects in Sri Lanka, Indonesia, Vietnam, Lao PDR and Cambodia, the results of which have been reported in previous publications, as noted below. In this volume, we bring together an update from research conducted in those countries and others. We trust the information will foster further development and spread of culture-based fisheries in Asia and beyond, and in doing so, bring livelihood and nutritional benefits to otherwise resource-poor communities.

Construction and installation of hexagonal wooden cages for fish farming

Author(s): Fabrizio Piccolotti | Published: 21/10/2013 | 2664 views

This document was prepared following the implementation of the Food and Agriculture Organization of the United Nations of a project in support of marine aquaculture development in the Republic of Djibouti.

During a series of field missions undertaken by the lead author, all the necessary materials for constructing a number of hexagonal wooden cages were assembled and cages were constructed and placed in the sea. The advantages of using locally available materials and the reasonable costs and ease of construction suggest the value of replicating this experience in other environments for the development of artisanal aquaculture. The basic knowledge and instructions provided in this manual are intended for present and future workers in aquaculture development dealing with the construction of small-scale artisanal floating cage for fish farming.

Public Sector Regulatory Systems for Ecosystems Based Management of Aquaculture - a GAP Analysis Tool

Author(s): Perera, R.P. | Published: 4/9/2013 | 2417 views

This document presents a tool, in the form of an audit table that can be used to broadly screen and identify gaps in the management systems of government agencies responsible for regulating aquaculture. These gaps, once identified, can be a first step toward building regulatory frameworks that can better deliver on jurisdictional ecologically sustainable development (ESD) and ecosystems approach to aquaculture (EAA) objectives. The end product of an assessment is a report for consideration by decision makers that lists the identified systems deficiencies and recommends aspects of aquaculture regulatory systems that should be developed, improved or subject to closer investigation. The audit tool is intended for self-assessment by interested government jurisdictions and should ideally be conducted by a small team comprising individuals with relevant expertise taken from within government agencies, external consultants or a combination thereof.

A fresh ethical perspective on the use of fishery resources in animal feeds

Published: 23/3/2009 | 3211 views
Fish is a biological resource, indispensable for the equilibrium of the entire food chain in many ecosystems, but also indispensable as a source of nourishing food and raw material for feed preparation. Unfortunately, this resource is limited and its over-exploitation will ultimately lead to a global collapse. Hence, there is a pressing need for initiating a global debate on the ethical nature of current practices on the use of this precious natural resource.
