Potentiometry for Cyanide Detection Applied to Fisheries Regulation

Paul Bryan Karlo R. Cudia*, Marc Lawrence J. Romero

Illegal cyanide fishing is practiced by some fishers to capture agile and otherwise inaccessible reef fishes easily. Economic incentives had prevented discontinuation of the practice despite regulations present. Aside from the well-known toxicity of cyanide, it is a concern whether the fish is for ornamental purposes or human consumption that cyanide is being used because of the environmental damage it can cause by killing off non-target species.

Method Standardization and Guidance Value Determination for Regulation on Formaldehyde in Round Scad (Decapterus spp.)

James Dela Cruz*, Paul Bryan Karlo R. Cudia, Aira Mae M. Seguerra, Marc Lawrence J. Romero

There are reports of traded Galunggong (Fil.), Decapterus spp., adulterated with formaldehyde (FA) to lengthen shelf life. FA is a noxious substance with negative repercussions to general consumer health. This warrants the determination of a guidance value due to a lack of a local regulatory value specific to Galunggong amidst rising Filipino public concern in the wake of importations complicated by the natural occurrence of FA in the marine fish post-mortem.

The farming of black-lip pearl oyster Pinctada margaritifera (Linnaeus, 1758) has been a viable industry for small and large-scale farmers in the South Pacific, but not in the Philippines, where it is monopolized by large-scale farms primarily based on the gold-lip pearl oyster Pinctada maxima.

The establishment of marine protected areas (MPAs) managed by the community has been a popular tool for coastal and resource management in the Philippines.

Vulnerability to Climate Change of “Giant Squid” (Thysanoteuthis rhombus) Fishery in Marinduque, Philippines

The Philippine fisheries sector has been affected by the impacts of climate change. Vulnerability to climate change pertains to a natural system's ability to cope with the negative impacts of climate change, variability, and extremes. Vulnerability assessment (VA) provides a framework for climate change impacts evaluation over a broad range of systems.

Utilization of Shrimp Head Wastes into Powder Form as Raw Material for Value-Added Products

Shrimp processing industries produce large amounts of wastes in the form of shrimp heads, shells, and tails, which are more or less 50% of the raw materials. Improper disposal of these nutrient-rich wastes can cause environmental problems if not duly managed.
