Early mortality syndrome of the type more accurately known as Acute Hepatopancreatic Necrosis Disease is causing major losses in marine shrimp in a number of Asian countries. The disease is associated with infection by a strain of the bacteria Vibrio parahaemolyticus. Here we describe a project to reduce the incidence of disease and improve crop outcomes for small-scale farmers in Thailand via an adaptive learning approach, implemented in association with farmer societies and collectives.

This report summarises the proceedings of the 16th meeting of the Advisory Group, held 26-27 August 2017 in Bali, Indonesia.

The practice of collecting penaeid shrimp seed and prawn seed from inundated agricultural fields adjacent to the Rupnarayan River has become a supplementary source of income for local communities. During the wet season each year, the river floods the extended open tract of unsown paddy fields. This article describes the traditional fishing practices, gear and livelihoods associated with capture and grow out of shrimp and prawn seed in this region of West Bengal, India.
