Jaime, I agree that BFAR could have done more with the data that was collected through the CDT laboratories. Last February there was a CDT workhshop sponsored by NOAA/NMFS held in Orlando, FL that BFAR attended along with others including myself. The two papers submitted by Mr. Gil Adora Deputy Director of BFAR indicates their willingness to reimplement cyanide testing. However, they also identified their need for external funding to establish and run a network of CDT laboratories similar to the network that was maintained by the IMA.
It is true that no exporter has been prosecuted for exporting cyanide-caught fish. Corruption does exist in the Philippines and may have affected the ability of BFAR to enforce Philippines laws.
Some exporters maintain state of the art filtration systems, others do not. I don't believe there is any law that requires exporters to maintain certain water quality standards. The MAC created standards but I don't believe thay had any way of forcing compliance (under ISO it is voluntary).
I have advised several companies that exported net-caught fish. AMRI exported net-caught fish when I visited the Philppines in 1999 and 2000. They admitted that the water used by many exporters came from Manila Bay and was seriously polluted (despite being treated before delivery to the export faciltiies). AMRI paid to have clean water taken from Subic Bay at a site I viisited in the Duty-Free Trade Zone.
Imperial worked with Ferdinand Cruz and I visited their Manila facility in 2005. They bought treated water that came from Manila Bay. I did some water testing on their water (using reagent test strips to measure ammonia, pH, nitrates, and total hardness). I also did quite a lot of testing of the water arriving in bags with marine aquarium fishes from the field using the test strips and using a Hanna pH and temperature hand-held meter. I also supplied them with kits by which they could do bacterial testing, copper, and chlorine testing.
Following my advice, staff added powdered alum (aluminum sulfate) to the concrete vat where the water coming by tanker truck from Manila Bay delivered saltwater to Imperial. After the alum precipitated the organics, the supernatant water was pumped to another large concete vat where liquid chlorine bleach (similar to Clorox) was added. The chorine residual was then neutralized using sodium thiosulfate pellets that I provided. These methods are similar to methods applied for sewage treatment. They can easily be applied by the exporters.
