Obando milkfish farms suffer P29M worth of losses due to fish kill
Bureau of Fisheries and Aquatic Resources (BFAR) said that 40 fish pen operators across seven barangays in Obando, Bulacan suffered from combined losses worth P29 million due to fish kill.
Based on the actual damage assessment results of BFAR Region III and the local government unit, the fish kill hit an estimated 130 hectares of milkfish farms in Obando, affecting a total of 250 metric tons of milkfish stocks.
According to BFAR, the fish kill happened on May 6, 2018 noontime triggered by unfavourable environmental factors particularly due to intense heat, which registered at 34 o C which coincided with low tide level at 0.050 meters.
“Light rain showers, prolonged cloudy skies and thermal fluctuations in the water due to changing weather conditions have been found to be the causes of dissolved oxygen depletion which, in turn, caused the fish kill,” BFAR said.
But the agency also noted that these factors only aggravated the already high risk of fish kill in some milkfish farms that have been found to follow a practiced stocking rate that is much higher than the BFAR recommended stocking rate of 3,000 fish per hectare.
“The local government unit in coordination with BFAR has initiated proper disposal of dead fish to ensure that these will not reach the market and cause any public health-related concerns,” BFAR said.
