We are all aware of the increasing pressure on our coastal resources to supply food and
income to many people living in the coastal areas in the region. Signs of over-exploitation of
many important marine resources are evident. The fishermen’s daily catch has dwindled and the
sizes of their catch have become smaller; they now have to go farther and spend a longer time at
sea to get some catch. This means that the rate of extracting the natural resources is faster than
their capability to reproduce and replenish themselves. This imbalance of resource extraction
and natural recruitment will ultimately result in the extinction of many of these important
species. Management measures need to be properly implemented to allow the resource to recover
and continue to support future generations. In addition, aquaculture practices that take into
consideration the health of the environment need to be promoted to ensure the sustainability of
the activity and maximize benefits for all in the long term.
With financial support from the Government of Japan Trust Fund, experts and representatives
from SEAFDEC member countries were gathered in a workshop to share experiences and
exchange ideas on resource enhancement and sustainable aquaculture practices. The proceedings
of the workshop are contained in this publication. This will be helpful as a guide and as an
additional source of information to those who are embarking on or engaged in resource
enhancement and aquaculture activities.

It is with pleasure that we launch the proceedings of the “International Workshop on Resource
Enhancement and Sustainable Aquaculture Practices in Southeast Asia”, held in Iloilo City from 5
to 7 March 2014.
This international workshop aimed to promote and augment regional initiatives on resource
enhancement and sustainable aquaculture practices, and to contribute to poverty alleviation,
livelihood and food security. A total of 149 participants attended the workshop, composed of
aquaculture and resource enhancement experts, scientists, representatives and observers from 11
Member Countries of SEAFDEC. It also featured 42 oral presentations and 15 poster papers. This
meeting was organized through the funding support of the Government of Japan.
The relationship of resource enhancement, sustainable aquaculture and healthy environment
is vital to the future development and sustainability of fisheries and aquaculture. For sustainable
aquaculture, we have to consider not only fish biomass for feeds, and broodstock for seeds in
natural resources, but also the healthy environment for their habitats. Stock releases in the wild
for enhancing depleted aquatic populations, are one of the effective ways to increase our natural
resources.
I hope that this proceedings will be utilized for the dissemination and promotion of
environment-friendly resource enhancement and sustainable aquaculture in the Southeast Asian
region.

The Aquaculture Department of the Southeast Asian Fisheries Development Center
(SEAFDEC/AQD) implemented regional programs on Resource Enhancement of Internationally
Threatened and Over-exploited Species in Southeast Asia through Stock Release (or Resource
Enhancement) and Promotion of Sustainable and Region-Oriented Aquaculture Practices
(Sustainable Aquaculture), these being important programs under the Fisheries Consultative
Group of the ASEAN-SEAFDEC Strategic Partnership (FCG/ASSP) Mechanism. These R&D
programs along with other two regional programs on Fish Health and Food Safety, were
conducted from 2010 to 2014 with financial support from the Government of Japan (GOJ-Trust
Fund). In March 2014, SEAFDEC/AQD, organized an international workshop on Resource
Enhancement and Sustainable Aquaculture (RESA) Practices in Southeast Asia at Iloilo City,
Philippines, as the milestone of these aforementioned regional programs. The workshop gathered
several distinguished local and international speakers and about 150 participants from 14
countries comprising of national and local government officers, academicians, as well as industry
stakeholders. It was a great opportunity for the participants to exchange timely information and
discuss research gaps and issues on broad topics under RESA practices in the Southeast Asia to
reduce poverty and secure livelihood in the region through further development of fisheries and
aquaculture.
As the program manager who launched these regional programs in 2010 and the chairperson
of the said international workshop, I am so happy that the invaluable information included
in this proceedings with full papers orally presented at the workshop, have become available
for use as reference by students, fisherfolks, aqua-farmers, practitioners, researchers, policy
makers, etc. Taking this opportunity, please allow me to say thank you very much to the authors
for their respective contribution to this proceedings. I would also like to express my sincerest
acknowledgements to Dr. Ma. Rowena R. Eguia, Dr. Fe Dolores Parado-Estepa, Dr. Nerissa Salayo,
Dr. Junemie Lebata-Ramos and other editorial staff of this proceedings for their hard work to
launch this issue after I left Iloilo as I ended my term in March 2014.
Finally, I hope for the further development of RESA practices in Southeast Asia, and I wish to
believe that this proceedings will make a great contribution to the pursuit of that aim.

By Dr. Chumnarn Pongsri, SEAFDEC Secretary-General
At the International Workshop on Resource Enhancement and Sustainable Aquaculture Practices
in Southeast Asia, 5-7 March 2014, Iloilo City, Philippines
This Workshop is important as it reiterates the critical fisheries scenario faced by the Southeast
Asian region as well as at the global level where the supply of fish and fishery products has been
limited by the deterioration of fishery resources and habitats; however, it should be noted that
the demand side has continued to increase over the years. The situation on deterioration of
fishery resources has called for improved utilization of fishery resources in a more responsible
and sustainable manner. Several initiatives were undertaken by countries in the Southeast Asian
region toward this, both on the aspect of capture fisheries and aquaculture. For aquaculture,
initiatives undertaken in the region cover ranges of R&D to come up with appropriate aquaculture
technologies; aquatic animal health management including disease surveillance and control;
safe use of chemicals and antibiotics in aquaculture; research on alternative protein sources
for aquaculture; and development and application of appropriate quality assurance systems in
order to comply with requirements of importing markets, etc. In addition to direct production
of aquaculture commodities, aquaculture technologies have also been developed and applied to
support resources enhancement.
SEAFDEC has also undertaken activities to support sustainable utilization of aquatic species
under international concerns, including scientific studies on the status of fishery resources in
order to serve as a basis for their conservation and management. SEAFDEC also has programs
and projects that aim to develop practical aquaculture technologies for species under international
concerns, including appropriate releasing strategies for resources enhancement. In addition,
SEAFDEC also takes leading roles in providing discussion forum among countries in the region
to come up with common conservation and management approaches for important species;
and the available scientific information and evidences on initiatives undertaken by the region
are envisaged to provide strong justification during further discussion at relevant international
fora in order to safeguard the fisheries sector of the region. As SEAFDEC Secretary General, let
me therefore encourage active inputs from the Workshop participants in order to come up with
fruitful results.
