1. Summary
Laguna de Bay has been found to have exceptional potential for fish culture in pens or ponds within the lake. This method of fish culture is relatively new and requires extensive work on an experimental basis to establish commercial feasibility. The Laguna Lake Development Authority (LLDA), as the authorized Government development agency for Laguna de Bay, is ready to undertake experimental and pilot programmes, to be followed by commercial ventures, for fish culture development on Laguna de Bay.
An FAO/UNDP assisted fish culture programme is proposed. The programme would extend
over three years at an estimated cost of U.S. $229 400 and local costs of 544 000. The
LLDA is designated as the cooperating body for the Government.

2. Background
Purpose of Study
The proposed programme is intended to assist the Authority in development of fish production through aquaculture techniques in enclosed areas in Laguna de Bay. The programme itself is not oriented to development of the lake fishery and it is intended that such development proposals be separately programmed.
Scope
The project would be undertaken at the existing Bay Fishery Station of the Philippine Fisheries Commission which would be made available to the LLDA for operation and management during the course of the study. The cooperating body for the Government would be LLDA. The study would be concerned with these programmes:
To improve the existing fish hatchery and experimental facilities of the station. The fish hatchery would raise fingerlings of the fish species needed for experimental work in the station in pens and enclosures in the lake. The station would also raise fingerlings for sale to commercial fish pen and pond operators.
To experiment with introduction of new species, mainly Tilapia nilotica, and balanced combinations of species for utilization of natural foods in the lake waters. Propagation and suitability for culture in Laguna de Bay would be developed on an experimental basis and would include work with local species such as Manila catfish, grey mullet, snakehead and others. The feasibility of utilizing locally available food sources would be studied.
To develop economical and durable designs of fish pens and various types of enclosures for use within the lake.
To initiate continuing studies of the dynamics of the aquatic biota for utilization in fish culture. Studies would also include analysis of changing ecologic conditions caused by the proposed hydraulic control structure on Laguna de Bay and by continuing development of the lake shoreland.
To establish management techniques in fish pen culture for all aspects of operation from stocking to cropping and marketing.
To assist the LLDA in establishment of extension services and the planning and organizing of cooperatives as soon as experimental findings warrant commercial development of fish pen culture on the lake.
Reference Studies
The proposed programme is based on conclusions and recommendations contained in this report and also in part on the LLDA Preliminary Programme of Work included as Appendix 1 of this report.

5. Availability of Housing for Experts
The LLDA will make available suitable rental housing for international experts at the University's College of Agriculture compound or equivalent area. The housing shall be in reasonably close proximity to the fishery station in order to avoid excessive time loss in daily travel from residence to place of work.
6. Related Projects
Previous assistance
Limnological studies were made under FAO experts Dendy and Morawa in 1959–60. A freshwater fishery investigation was made by FAO expert Parsons in 1961. A statistical analysis of the Laguna de Bay fishery was made by Shimura and Delmendo in 1968–69 (see (FAO/UN, 1961; FAO/UN, 1962, and Shimura and Delmendo, 1969). A United Nations feasibility survey of Laguna de Bay was made in 1968–70 on multipurpose development of the area (see UN, 1970).
7. Follow Up
It is anticipated that the results obtained from this project will form a basis for development of 5 000 ha or more of commercial fish pen operation on Laguna de Bay. These operations would be undertaken by fishery cooperatives assisted by the LLDA and it is anticipated that additional assistance in the fields of extension work and management of cooperatives and follow up will be desirable. In addition, some continuing assistance on fish culture development will probably be desirable. After findings become available from the experimental work proposed in this study, major improvements may be possible in the overall lake fishery, which covers an area of 70 000 to 80 000 ha. The nature of the follow up action would be determined in the course of the third year of the proposed FAO/UNDP project.
