Layout and design of aquaculture project: pen and cage systems
MetadataShow full item record
Various floating cage and fishpen designs are employed to meet enclosure requirements of shrimp and milkfish brood-stock, and for rearing of other finfish at the lgang Substation of the SEAFDEC Aquaculture Department in Nueva Valencia, Guimaras Island. In addition, support facilities are constructed like pontoon catwalks, wet laboratory, pumphouse, power house and researchers' quarters. With the establishment of the Department's Naujan Substation in Mindoro in 1978, floating cages and transport cages are also designed and installed. Following encouraging results of milkfish broodstock studies leading to natural spawning, rematuration and re-occurrence of natural spawning and completion of the milkfish life cycle, a development plan for the lgang Substation was prepared for full development of the Substation as a mariculture center. Specific recommendations towards this end are presented.
