World population is projected to increase drastically in the coming decades which might bring about shortage of food. Freshwater fish are considered to be one of the most promising commodities that can contribute to increased food production in a sustainable manner. Common in the Asia-Pacific region, freshwater aquaculture provides diverse benefits to rural farmers including income generation, improved nutrition and sustainable livelihoods through integrated farming system.
The main objective of this symposium was to provide a venue for information sharing on extension of small-scale aquaculture, specifically targeted to those individuals and relevant organisations involved in various aquaculture development projects. The symposium also assessed and presented the effectiveness of “farmer-to-farmer extension” approaches in the implementation of relevant aquaculture development projects in the region.
The symposium was organised by the Japan International Cooperation Agency (JICA), NACA and the Thai Department of Fisheries for stakeholders involved in the JICA-assisted projects in Cambodia, Lao PDR, Myanmar, Benin and Madagascar. The symposium was also attended by representatives from other countries in Asia and Africa including Cote d’ Ivoire, Indonesia, Malaysia, Nepal, Philippines and Zambia.

Small scale aquaculture profile in Lao PDR
The Lao government has set a target to increase fish supply to 24 kg/year/person by 2020. In most cases of aquaculture extension, exotic species have been used as target species. In view of biodiversity, establishment of habitat and hybridizations with indigenous species in the natural water body, this practice may cause deterioration of the natural biodiversity. Therefore, to protect the diversifications, aquaculture extension using indigenous species should be promoted.
Small-scale freshwater aquaculture extension development in Indonesia
Freshwater aquaculture production in Indonesia has significant contribution to the total aquaculture production. In 2012 freshwater aquaculture production was 2.15 million tons or 68% of the total aquaculture production of 3.16 million tons (excluding seaweed). The major commodities cultured are common carp, tilpia, pangasius, giant gouramy, African catfish, java carp, and freshwater prawn. Small-scale freshwater aquaculture extension is very important to assist the fish farmers in the region.
The emergence of the cheapest farmed freshwater food fish in the Philippines
In the context of aquaculture technological extension, this paper and accompanying presentation reveal how the government and key UN partners, initiated the farming and breeding of Asian and Indian major carps in the country between 1965 up to late 1970s. Emphasis is given on bighead carp Aristichthys nobilis, which as per 2011 and 2012 official agricultural statistics, ranked 3rd in freshwater aquaculture (17,464 MT) and 6th on inland capture fisheries output (12,119 MT).
Small-scale freshwater aquaculture in Nepal
Modern aquaculture practices in Nepal started around the 1950s). Since then, aquaculture has contributed about 1% of GDP. The national average production from pond aquaculture is about 3.6 million tons/ha. However, the range of fish production varies from about few hundred kilograms to 7.0 million tons/hectare depending upon different farming and management system. Aquatic resources located at different altitudes can offer potential for different fisheries and aquaculture activities in Nepal.
Small-scale aquaculture extension in Cote d'Ivoire
Promoting small-scale freshwater fish farming in Côte d’Ivoire was done in two stages. First was awareness and establishment stage (1974-1990) implemented by dense and diverse state support. The second was the professional stage (1992-2002) executed by specific regional projects. Activities targeted small-scale fish farming including promotion of quality amenities, reproducible by the promoters; marketing; and the promotion of research and development focused on the needs of stakeholders.
Small scale aquaculture development in Malawi
Fisheries resources play a very important role in Malawi’s national economy, in terms of food and nutritional security of the population. It contributes about 60-70% of annual animal protein supply of the nation. In fact, fish is the readily available source of animal proteins consumed in small amounts among Malawian daily meals, thereby nutritionally supplementing essential amino acids in their diet. Fisheries provides source of employment to over 300,000 people through fishing and associated activities.
Status of small-scale aquaculture in Zambia
The largest percentage of aquaculture production in Zambia comes from small-scale fish farmers. This is mainly because there are many small scale fish farmers compared to other categories. In comparison to small-scale fish farmers, there are very few commercial or large-scale fish farmers. This situation suggests that one of the ways for effectively increasing aquaculture production is to improve fishpond productivity and commercialization of aquaculture production systems.
