We adopted a participatory action learning approach aimed at improving pond productivity through engagement of 17 small-scale fish-farmer cooperators to adopt different ulang culture systems—ulang monoculture, ulang-rice polyculture, and ulang-tilapia polyculture. This paper focuses on comparing the production and profitability of ulang monoculture and ulang-tilapia polyculture. The cooperators were guided to follow proper protocols in pond preparation, feeding, and water management. Results showed an average survival rate of 65 percent for ulang monoculture; and 59 percent and 77 percent survival rates for ulang and tilapia in polyculture system, respectively. The major problems encountered across regions were unavailability of post-larvae; distance of post-larvae source; water av...

Twelve farmer-cooperators employed ulang monoculture and eight employed ulang -tilapia polyculture. In Region 8, all farmer-cooperators conducted both monoculture and polyculture systems. This paper is focused on comparing ulang monoculture and ulang -tilapia polyculture. The cooperators were asked to follow protocols recommended by the project for both culture systems. Results showed an average survival rate of 65.00 ± 9.07% for ulang monoculture; while 58.79 ± 15.23% and 76.54 ± 11.72% survival for ulang and tilapia in polyculture, respectively. The major problems encountered across regions were: a) unavailability of post-larvae (PL), b) distance of PL source, c) water supply, d) presence of predators, and e) inconsistent implementation of technical interventions by the cooperators. Unless the farmers realized that the profit...

Hence, the national government initiated the implementation of Philippine National Aquasilviculture Program aimed to achieve food security, promote sustainable development of fisheries resources, and reduce poverty incidence among fisherfolk and other disadvantaged groups. To this, the Mindanao State University at Naawan served as the academic partner of the Bureau of Fisheries and Aquatic Resources Region 10 in implementing three major projects namely, mangrove plantation, aquasilviculture and king crab hatchery in the community. Several people’s organizations in Misamis Oriental, Misamis Occidental and Lanao del Norte served as the project beneficiaries and implementors, particularly on mangrove plantation and aquasilviculture projects. After a year of mangrove planting, 621,852 living propagules survived (48.47%) from 1,282,7...

Two patches of Cochlodinium sp. bloom, associated with fish kills in Kalangahan Pt.-Manticao Pt., Iligan Bay, caused localized water discoloration from the usual ocean blue to rusty brown or reddish brown to blackish. The first patch, located near fish-aggregating device (FAD) areas, spanned 2 km wide, while the second patch, located near a fish corral, spanned 500 m wide. These patches occupied the water column from surface to 5 m depth, but a thick mat formed at 0.5 m to surface. Patches decreased as the bloom began to decline. The observed dead demersal and pelagic fishes coincided with highest bloom density of 3.1 x 10 4 to 3.8 x 10 4 cells ml-1 of Cochlodinium. Dissected gills and stomach contents of fishes killed in HAB-affected areas did not reveal any indication ...
