Preface
Seaweeds are among the fishery resources abundant in shallow coastal waters. However, maintenance of its maximum sustainable yield appears to be difficult to achieve at present because the coastal zone has been heavily damaged by man - overfishing and overharvesting of marine life, habitat destruction brought by illegal fishing, pollution, siltation, and excessive deforestation which stem from increasing population and greed for money. The emergence of Western Visayas as a potential site of Kappaphycus and Eucheuma farming can contribute to the country's seaweed production and provide additional livelihood to marginal fishermen especially since coastal production has been declining in recent years. Indeed, several reports have attested to the profitability of seaweed farming. Thereby, farming other economically important seaweed species in areas where cultivation is possible must be encouraged. Towards this end, the taxonomy, ecology, and distribution of seaweeds must be known. The seaweed resource of Panay is rich but very little information is available on its taxonomy, distribution, ecology, and economic importance. This practical book on the seaweeds of Panay acquaints and provides information to members of the academe and research institutions, policy makers, fishermen, and businessmen regarding these aspects. The book consists of four major parts: (1) Introduction - reviews the literature, habitat, distribution, morphological structure, and reproduction; (2) Classification - describes the classes to which seaweeds generally belong; (3) Collection and Preservation - explains the procedure used in treatment of specimens; and (4) Taxonomic List. A glossary is included to enlighten the reader of technical terms used. A list of references is also added to widen the user's literature. All species listed and described in this book are macrobenthic and were collected in Panay and Guimaras Islands.
