The study was conducted to determine the anthropogenic activities and water
quality in relation to the abundance of greasyback shrimps (Metapenaeus ensis, De Haan,
1844) in Ylang-Ylang Estuary in Noveleta, Cavite. Anthropogenic activities including
fishing and aquaculture practices, and discharge of untreated wastewater from household
and transport system were occurring near the estuary. Physico-chemical of water
parameters such as temperature, turbidity, pH, total dissolved solids, salinity,
conductivity, dissolved oxygen, nitrates, phosphates and total coliform were monitored
for five months from June to November 2018. Temperature and pH from two sampling
stations in five-month sampling periods falls within the standard set by the DENR for
Class SB waters except phosphates and total coliform. Nitrates also passed the standards
for Class SB water except from the month of June in brackish water. Mann-Whitney U
test revealed that the physico-chemical quality of water of the two sites are not
significantly different while Friedman test showed that quality of water including
temperature, turbidity (only site 2), conductivity, salinity and phosphate fluctuate across
five sampling periods. Statistical analysis also showed that the abundance of greasyback
shrimps is positively correlated with significant effect with pH and TDS.
