Title: Growth and absorption response of Perna viridis(Lin, 1758) to fish farm water quality in Valladolid, Carcar, Cebu, Philippines


The extractive species, green mussel (Perna viridis) has been integrated into the existing commercial finfish culture of Chanos chanos and Trachinotus blochii in Valladolid, Carcar Bay, Eastern Cebu, Philippines, following the Integrated Multitrophic Aquaculture (IMTA) concept. Two sampling sites (573 m apart) were selected; the experimental site, and control site. Biomass and growth rates of this species was measured monthly, along with physico-chemical parameters in the two sites, monitored for a period of up to one year. Results showed that P. viridis was adopted to the fish farming site where physico-chemical parameters like temperature, salinity, pH, dissolved oxygen were within the optimal range. Growth of P. viridis was mainly affected by predators and fouling organisms present during culture which reduced their potential biomass and growth rates. The introduction of green mussels in the fish farm appeared to have checked the adverse effects of fish culture activities daily inputs of commercial feeds, could led to the suspended solids. Transplanted green mussels grew into marketable after 7 months with average specific growth rate (SGR) reached highest level at 1.03% in February 2019. The use of IMTA concept, following the culture of green mussels within the cages area is found to work well in the culture of milkfish/pompano, and should be promoted and expanded in the Philippines.
