FOREWORD

LIBFISH Technical Briefing Notes (TBN) are intended as preliminary communications about ongoing or recently completed work undertaken through the various Project components. This eighteenth number in the series outlines model proposals for small-scale fish farming units, as prepared by F. Vallet, FAO Senior Aquaculture Advisor.

TBN No. 18 thus documents further contributions towards the fulfillment of Project terms of reference related to aquaculture in Libya. The Project's Aquaculture Working Group is concerned, amongst other things, with: assessment of national aquaculture potential and existing capacity and requirements; site visits and evaluation; training activities in a wide array of aquaculture techniques including fry and feed trials, operation of experimental feed, hatchery, and supporting laboratory and production-related facilities; and the preparation of advisory reports to the Secretariat of Marine Wealth.
