      Recent improvements in hatchery production technology for high-value marine finfish species such as groupers have led to an increased interest in setting up hatcheries to produce fingerlings for aquaculture. Small-scale hatcheries make this technology available to poor people in developing countries. Capital costs for small-scale hatcheries are relatively low, and the profitability of these ventures ensures rapid payback of capital investment.

      This guide provides an outline of the requirements to establish a small-scale marine finfish hatchery, particularly the economic aspects. It is intended to provide sufficient information for potential investors to decide whether investment in such ventures is appropriate for them. The guide provides some basic technical information in order to give an indication of the level of technical expertise necessary to operate a small-scale marine finfish hatchery. However, it is not intended as a detailed technical guide to the operation of small-scale hatcheries. Additional resources, such as training courses in marine finfish hatchery production, are available and these are listed in this document.

      Development of small-scale hatcheries may be more appropriate where there are existing marine hatchery operations, e.g. for shrimp or milkfish. By definition, small-scale hatcheries do not have broodstock facilities, so a supply of fertilised eggs (usually from a larger hatchery) is essential. Access to fertilised eggs and experienced hatchery staff will limit the application of small-scale hatchery technology. Despite this, there is considerable potential for this technology to be widely adopted.

      This guide has been written by a team of experts in marine finfish aquaculture who have been involved in a multinational collaborative research project since 1999.

      Shrimp culture and the environment 

      MJ Phillips - In TU Bagarinao & EEC Flores (Eds.), Towards sustainable aquaculture in Southeast Asia and Japan: Proceedings of the Seminar-Workshop on Aquaculture Development in Southeast Asia, Iloilo City, Philippines, 26-28 July, 1994, 1995 - Aquaculture Department, Southeast Asian Fisheries Development Center
      This paper reviews the interactions between shrimp culture and the natural environment. It considers and gives details of the effects of shrimp culture on the environment and the effects of environmental change on shrimp culture. Examples are given where the environmental impacts on and of shrimp culture have caused serious economic losses to shrimp farmers. The paper concludes that economic sustainability is and will continue to be closely related to how the shrimp farming industry deals with environmental problems. Strategies are considered for improved environmental management of shrimp aquaculture, and priorities are highlighted for future research on the relations between shrimp culture and the environment.
