JOINT SCSP/SEAFDEC WORKSHOP ON AQUACULTURE ENGINEERING (with emphasis on small-scale aquaculture projects) VOLUME 1 - GENERAL REPORT


REGIONAL

VOLUME 1 - GENERAL REPORT

Held at SEAFDEC Aquaculture Department Facilities
Tigbauan, Iloilo, Philippines
27 November – 3 December 1977

A priority activity of the SCSP is to stimulate the development of aquaculture as an integrated part of the total development of fisheries. Based on its work to date, one of the major constraints found is the lack of practical, sound, workable, engineering practices to guide development. It is felt that all the expertise required exists in the region, but that it is unevenly distributed and not well known among the countries.
This Workshop has provided a vehicle for the exchange of very useful engineering practices and further it has given valuable guidance to the Programme in its future activities to assist the region particularly in small-scale fisheries development.
It has been carried out with close cooperation of SEAFDEC in providing its facilities and staff and as well as the lodging and living expenses of the participants while attending the Workshop. The Philippine Bureau of Fisheries and Aquatic Resources assisted also in the organization and implementation. Close collaboration, support and participation was given by the private sector, through the Philippine Federation of Fishfarm Producers, Inc.

PREPARATION OF THE GENERAL REPORT

This General Report of the Workshop proceedings was prepared by the South China Sea Fisheries Development and Coordinating Programme, based in Manila, in consultation with SEAFDEC Aquaculture Department, Tigbauan, Iloilo, Philippines. It presents the recommendations and a condensed version of principal events and technical matters related to the Workshop. A separate Technical Report presents the Contributed Papers and technical discussions of the Workshop. The Workshop was jointly sponsored by the SEAFDEC Aquaculture Department and the SCSP. The Philippines, through the Bureau of Fisheries and Aquatic Resources, was the host country. The reports were compiled/prepared and edited by Mr Robert H. Gedney, Workshop Director and Dr Herminio R. Rabanal, Fishery Officer (Aquaculture Development) of the SCSP staff.

This Workshop was an important milestone in relating the Technical aspects of the on-going and emerging programmes of SEAFDEC with the needs of the countries participating in the Workshop. It is through these kinds of dialogues that we can keep our efforts in tune with the problems being encountered in the field and which need special attention. It has been our pleasure to furnish the use of our facilities and resources to support the logistics of the Workshop.
