Mobile Hatchery: A New Tool for Fisheries Extension  

Mobile Hatchery: A New Tool for Fisheries Extension

In 2002, staff from the Aquaculture of Indigenous Mekong Fish Species sub-component, Thailand (AIMS-Thailand) developed a mobile hatchery for use in remote rural areas. The performance of the hatchery in the field exceeded expectations. It proved more flexible than anticipated and the percentages of eggs produced, fertilized, and hatched, were comparable with results achieved in a standard hatchery. The hatchery allows artificial wild fish breeding in locations where transportation of these fish from the main hatchery is impossible. Demonstrations of the hatchery have taken place in Nakhonphanom, Udonthani, Mukdahan and Nam Houm (Lao PDR). . A hatching hapa measuring 2x2x0.5 m with flow-through water supply can be used to hatch 3.4x106 eggs of Barbodes gonionotus (93% fertilization rate and 86% hatching rate), 1.5x106 eggs of Labeo rohita (74% fertilization rate and 95% hatching rate) or 1 x106 eggs of Cirrhinus microlepis (60% fertilization rate and 30% hatching rate). Funnel-type incubators with 15 L volume can be used to hatch 1.0x105 eggs of Probarbus jullieni (60% fertilization rate and 40% hatching rate). Demonstrations of the mobile hatchery attracted a lot of interest from local people and helped to raise awareness of issues concerning fish conservation.
