Effect of garlic, Echinacea, organic green and vet-yeast on survival, weight gain and bacterial challenge of overwintered Nile Tilapia fry (Orechromis niloticus)

The purpose of this study was to examine the effect of some immunostimulants and probiotics on the survival rate, final weight, and disease resistance of overwintered tilapia fry. There were five treatments: T1 (control) fed a balanced diet (35% protein) without additives. Treatments 2 to 5 were fed diets supplemented with 4% garlic, 4 g/kg Echinacea, 4 g/kg Organic Green or 4 g/kg Vet-Yeast, respectively.

Diversification of aquaculture for empowerment to fisheries through institution village linkage programme (IVLP) in Kerala, India

Technology Assessment and Refinement through the Institution Village Linkage Programme (IVLP) is the latest participatory extension model successfully undertaken by the Indian Council of Agricultural Research in India. The Central Marine Fisheries Research Institute has been implementing IVLP since 2001 to assess and refine the technologies of the coastal agro ecosystems at Elamkunnapuzha village (Vypeen Island) in the Ernakulam District of Kerala.

Dissemination and adoption of milkfish aquaculture technology in the Philippines

This publication is adapted from the report of the project "Dissemination and adoption of milkfish aquaculture technology in the Philippines. 2007" The key lessons learned are highlighted: 1)Strengthen extension systems to better disseminate improved milkfish hatchery and nursery technologies. 2) Enhance the efficiency of milkfish grow-out culture by introducing restrictive feed management and polyculture with shrimp. 3) Train producer communities to add value by processing their milkfish harvest. 4) Improve milkfish farmers access to credit.

Development of sustainable aquaculture project: progress report (1 July 2001 - 30 Sept 2001)

The Development of Sustainable Aquaculture Project (DSAP) was authorized by USAID. This report covers activities for the three months of the project, 1 June 2001 through 30 September 2001. The main thrust of the DSAP is to sponsor on-farm aquaculture production demonstrations implemented through co-operating NGO partners. These demonstrations are expected to show farmers and their neighbors the profitability of managed aquaculture systems as small business operations.

Culture of prawn in rotation with shrimp.

A progressive farmer in Tamil Nadu state, India experimented with crop rotation and successfully cultured Penaeus monodon during the dry season and Macrobrachium rosenbergii during the wet season. The details of M. rosenbergii culture are discussed in this article. Rotation with M. rosenbergii did help the farmer overcome the disease problem since farmers who exclusively cultured P. monodon in the nearby areas during the same season suffered losses due to white spot disease.

Community management of Mekong River resources in Laos

The Mekong River is one of Asia's greatest rivers. It is the lifeblood of millions of small-scale farmers and fishers in China, Burma, Thailand, Laos, Cambodia and Vietnam. In the Lao People's Democratic Republic (Lao PDR), the river is particularly important because for the landlocked country, the Mekong is "the Sea of Laos." In southern Lao PDR, fisheries for native fish species constitute an extremely important source of subsistence protein and income for local people.

Community-based fish culture: a viable coping strategy for farmers in the Mekong Delta?

Floodplains are characterized by a period of several months when the land is not available for agriculture and large and open areas are used for fisheries. Enclosures in the flooded areas can be utilized to produce a crop of stocked fish, in addition to naturally occurring self-recruited species. The WorldFish Center and the Research Institute for Aquaculture no2 (RIA 2) tested options for community-based fish culture in floodplain enclosures in the Mekong Delta. The trials yielded fish production in the range of 61–179 kg ha-1.

Clam farming in the Mekong Delta, Vietnam.

The Mekong Delta region in southern Vietnam has high potential for coastal aquaculture, including mollusc culture. Many mollusc species are cultured for domestic and export markets including white clam (Meretrix lyrata Showerby) and blood cockle (Arca granosa). Techniques for clam farming include the nursery and grow-out phases. At present, there are approximately 600 coastal families engaged in clam farming over a total area of 1,870 ha, of which 82.63% is used for the grow-out phased and 17.7% for the nursery phase.

Aquaculture technology transfer to smallholder farmers in Malawi, Southern Africa.

Details are given of activities conducted in Zomba, Malawi, in order to demonstrate new aquaculture technologies and encourage their use by smallholder fish farmers. The following technologies were introduced: napier grass as a pond output; use of a reed fence for harvesting fish; developing a high-quality compost as a pond input; vegetable-pond integration; chicken-pond integration; smoking kiln; pond stirring; and rice-fish integration. The reactions of the farmers to these technologies and their testing by the farmers are outlined briefly.

Aquaculture options for alternative livelihoods: the experience of the Adivasi Fisheries Project in Bangladesh

The Adivasi Fisheries Project (AFP) set out in 2007 to help Adivasis in the north and northwest of Bangladesh find new and more sustainable livelihoods. It is based on 2 decades of WorldFish Center research in Bangladesh on aquaculture techniques for smallholders and community fisheries management and targeted disadvantaged rural miniorities called Adivasi. The project significantly improved Adivasi households’ livelihoods. Monitoring survey results found all of the fishery-related livelihood options profitable.
