Item Value chain analysis of Lampirong (Placuna placenta) in Oton, IloiloBito-on, Edrian T.; Haro, Errielle Nicole M. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2023-06)Lampirong (Placuna placenta) is a highly valued bivalve in the Philippines due to its economic value. It was once abundant in Oton and was overexploited, leading to its stock depletion. Southeast Asian Fisheries Development Center’s (SEAFDEC) efforts to enhance the stock in Oton resulted in the resurgence of lampirong stock and industry. The lack of transparency in the lampirong industry and studies on the linkages between the actors in the lampirong business have gotten little to no attention following the resurgence of lampirong and the recovery of the shell craft industry after the depletion. A Value Chain Analysis (VCA) was conducted to evaluate the overall performance of the local lampirong industry following the stock enhancement. Using an interview schedule, the researchers gathered primary data from a total of 20 study participants. They were interviewed in the month of May and were grouped according to the tasks they carried out. The biggest player of the chain turned out to be the Institutional Buyers as they are the bulk buyers and sellers of lampirong in the market. The industry resembles a competitive market as the majority of participants were price takers and the products are homogenous. As the lampirong transforms from raw to processed forms, its net added value increases as it goes through the various actors. Lampirong processing incurred the highest cost but also generated the highest value-added. Diving lampirong was performed by men while processing and trading were dominated by women.Item Diversity and population structure of sea cucumber species in Taklong Island Marine Reserve, GuimarasBearnod, Christine F. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2014-04)The increasing demand of sea cucumbers in the market leads to the global exploitation of this animal. Marine reserve protects the marine biodiversity and teaches the people in the communities to manage their marine resources wisely. This study examined the diversity, species characteristics and population structure of sea cucumbers in five sites around Taklong Island Marine Reserve namely, Binabaywan, Kalirohan, south side of 2nd sandbar, north side of 2nd sandbar and Tarakpan. The species composition and abundance were determined through transect walks and plot along transects. Sea cucumber density was estimated by randomly positioned 1 square meter plots in each site. There were 11 sea cucumber species found. There were 9 species under Order Aspidochirota all in 1 Family Holothuriidae and 2 species in Order Apodida in 1 Family Synaptidae. A total of 64 individuals were sampled in 5 sites. The most widespread and the dominant species was the non-commercially valuable Synapta maculata (n = 32) followed by the low-value Holothuria pulla (n = 9) and Holothuria atra (n = 8). Kalirohan had the most number of species (Σs = 6) and individuals of sea cucumbers. The low number of holothurian species encountered in the Marine Reserve might be due to the limited sites surveyed, cryptic behaviour of the species and the possibility of poaching in the area.Item Value chain analysis of sergestid shrimp (Acetes Spp.) in Oton and Tigbauan, IloiloAndres, Junaelle Kyla B.; Iguban, Myra Marie B. (Division of Social Sciences, College of Arts and Science, University of the Philippines Visayas, 2014-04)The sergestid shrimp industry in the municipalities of Oton and Tigbauan has contributed to income and employment of the local shrimp catchers, traders, and processors. This study described and analyzed the value chain of sergestid shrimp in these municipalities. Specifically, the study described the market actors, their marketing practices, and the value chain; determined the revenues received, costs incurred, and gross margins received by the market actors; identified roles performed by the men and women in the sergestid shrimp value chain; and identified the problems facing the market actors. Data were collected from personal interviews of 14 shrimp catchers, 9 raw shrimp traders, 11 shrimp processors, and one shrimp product trader. The shrimp catchers caught an estimated 132,758 kilograms of shrimp in a year. Most were sold (129,182 kilograms, 97.31%), with only the three commission houses handling an estimated 128,702 kilograms (96.94%). The major outlets of the commission houses included raw shrimp retailers and different types of shrimp processors. The highest average selling price (P372.73/kg), gross margin (P168.65/kg), and net returns (P161.39/kg) was received by one shrimp product retailer. Generally, the shrimp catchers were price takers, with the commission people as quantity leaders and seemingly price leaders. The net added value of shrimp increases as it is transformed into new forms such as the shrimp paste, dried shrimp, and shrimp mill. The men performed more strenuous roles (such as catching, hauling, and loading shrimp) while the women performed more time-consuming roles (buying inputs in catching or processing and selling). Adding value to the raw shrimp through processing can increase returns. Creative ways to create demand for raw and processed shrimp should be introduced. New processing technology, new market outlets for processed shrimps, and better packaging can increase demand for processed shrimp. With more players in the market, price can be set by more players.
