PUBLICATION: A Guide to Small-Scale Marine Finfish Hatchery Technology

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.

This research project, funded by the Australian Centre for International Agricultural Research (ACIAR), has made an important contribution to improving the sustainability of marine finfish aquaculture by improving hatchery production of high-value species, particularly groupers.

Further details of research undertaken as part of project FIS/97/73 Improved hatchery and grow-out technology for grouper aquaculture in the Asia-Pacific region are available from the project website: http://www.enaca.org/aciar/

Backup - Backyard Aquaponics

Backup - Backyard Aquaponics | Aquaponics~Aquaculture~Fish~Food | Scoop.it
This means you will need to have your backup system already thought out before hand, and it will need to be automatic. There are a couple of simple ways you can do this. We like to use AC/DC aerators, these are air pumps with internal rechargeable batteries in them. Normally they run while plugged into the power, pumping air through air lines and air stones in the fish tank. When the power goes out they switch automatically over to their internal batteries and continue to pump air into the water keeping the fish alive for the life of the battery within the unit, often up to 10 hours. When the power comes back on, the internal battery is recharged.
Charlie Dare's insight:

Also you can have a pressure switch that automatically turns on a backup water pump if two are installed in sump return to fish tank pipes~.Gensets generally need starting in a power failure but oxygen is most important to keep the fish alive

Charlie Dare's insight:

"

It is not complete and it is brief, but it is a good starting place to get an understanding of the role of various microbes in the lives of tropical fish and the gardening of plants.  Without them, there would be no way to sustain the higher forms of life like tropical fish and the organic vegetables they fertilize. 

A good understanding of the Nitrogen cycle and the way that toxic wastes created by lifeforms are eliminated from the habitat is important when dealing with closed systems such as an Aquaponic home garden, just as it is in a commercial endeavour.  I certainly hope that additional parts will be published. "I cant add further to comments but brightagrotech.com has much more valuable information at their site.This has also been discussed by others in their blogs like Murray Hallam and others as all cover much of the same topics~
