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. A series of need based location specific technology intervention plans have been introduced to overcome the social and biological constraints on farming practices in fisheries, livestock and agriculture, and implemented with the active participation of the stakeholders. The inferences drawn from IVLP ultimately form a package suitable for enhanced production in the costal agro ecosystem for replication to other areas with similar characteristics. This paper gives a brief account of the treatment packages applied in fisheries through various technological interventions and discusses the consequent yield and benefits obtained. The ‘integrated whole village development’ through the involvement of multi institutional teams and a participatory approach was accorded prime importance in the IVLP of Elamkunnapuzha, with a greater emphasis on marginal and small farmers and specifically focusing on women for poverty alleviation and equity under the coastal agro ec

Growth and survival rates of hatchery-produced and wild milkfish fry grown to fingerling size in earthen nursery ponds

Growth and survival rates of hatchery-produced and wild milkfish (Chanos chanos ) fry grown to fingerling size were compared. Data show no significant difference between the 2 fry. At a recommended stocking density of 30 fry/m super(2), hatchery-produced milkfish fry could attain fingerling size of almost 2g with a survival of 68%. The study indicates that hatchery-produced fry/fingerlings can equal the culture performance of the wild fry. Comparative performance of hatchery-bred and wild fry should encourage intensified research on milkfish broodstock development and refinement of induced spawning methods.
