Manila Bay is not positive for red tide
Following the high shellfish mortality in Cavite, the Department of Agriculture’s (DA) Bureau of Fisheries and Aquatic Resources (BFAR) said Manila Bay isn’t positive for red tide.
“Having no latest advisory saying that Manila Bay is positive for red tide, consumption of shellfish from the said fishing ground is safe,” BFAR said.
“The general public is advised, however, to collect only live shellfish and wash them properly before cooking,” it added.
Following the reported shellfish mortality in the growing areas of Bacoor and Sangley Point in Cavite, the DA-BFAR dispatched again its Fisheries Protection and Law Enforcement Group (FPLEG), together with the BFAR National Fisheries Laboratory Division (BFAR-NFLD) and technical personnel from BFAR 4A to investigate the incident.
Based on the initial laboratory report, the level of salinity in the areas which ranged from 19-25 ppt is lower than the required level for shellfish survival which is 27-35 ppt. The heavy rainfall in the past few days may have triggered the salinity of the water to drop.
Test also showed that dissolved oxygen levels in the sampling areas are low. High concentrations of ammonia and phosphates were likewise detected. These chemicals, at high levels, may cause detrimental effects to fish and other marine life.
