Plans and programmes of the SEAFDEC Leganes Station with emphasis on varied layouts and design of ponds

As the importance of engineering to aquaculture becomes more apparent it is also realized that the physical properties of a pond have a strong influence on its productivity. This article reports the plans and programmes of the SEAFDEC Leganes station on pond design with reference to site location, ponds and supportive facilities, their general layout, design and specifications and construction. Shrimp and milkfish culture is mentioned. Problems are considered and finally recommendations are made

Milkfish culture in brackishwater ponds

The manual is intended as a guide for operation in milkfish farming. It is presented under the following major sections: 1) Handling of fry - counting, storage and transport; 2) Pond layout and construction - selection of farm site, layout, construction, plan and specification; 3) Pond operation, culture and management - nursery pond management and rearing pond operation; 4) Harvest and post-harvest - harvest, post harvest, and processing; and 5) Economics and costing - cost of construction, cost of operation, and production/yield

Comparison of the silo and broadcast methods of applying organic fertilizer in milkfish, Chanos chanos (Forsskal), ponds

The efficacy of the silo and broadcast methods of applying organic fertilizers in ponds for the production of pond-floor, microbenthic biological complex, a natural food source known as lablab, was tested in 1-ha ponds, replicated thrice in time. Although there were no statistically significant differences (P > 0.05) in milkfish growth, survival and production between the two treatments tested, after 90 days production tended to be higher in ponds prepared with the silo method. Advantages of the silo method are that it is less laborious, cheaper, and less time consuming than the broadcast method and results in consistent lablab growth until the end of the culture period

Polyculture of bighead carp, common carp and Nile tilapia in cages in Laguna lake.

Increasing fish production through polyculture was clearly demonstrated to the fishfarmers in Laguna lake. The rearing of different species of fish of proper number and species combinations had resulted to the efficient utilization of all the available food niches/zones in the lake. Fish production is site specific in Laguna lake. Wide variation in growth increment and fish yield were observed among the different bays and among farm sited within a bay. The final mean weights of the fish species were 355 mg to 2300 g for bighead carp, 32 g to 103.3 g for tilapia and 8.3 g to 1800 g for common carp
