A subadult female Spinner Dolphin (Stenella longirostris) was found dead along the beach by residents of Brgy. Balanga in Lemery, Batangas last Monday.
Bureau of Fisheries and Aquatic Resources (BFAR) 4A PFO Batangas headed by Mr. Aljon Andrade together with Marco E. Espiritu, DVM, BFAR-4A Veterenarian, and PFO staff Donna Fe Valenzuela, responded to a call from LGU of Lemery, Batangas, that a marine mammal was stranded at the coastal barangay.
Dr. Espiritu immediately conducted a necropsy to identify the possible cause of death and collected samples subject for laboratory testing.
According to the results after the examination of tissues, the first possible cause of death is capture myopathy, resulting from the extreme stress suffered during and after capture, handling, restraint and transport.
There are numerous gross visible signs that the dolphin is a possible bycatch of a certain fishing gear as characterized by linear to reticular abrasive patterns on the skin. Second is stress myopathy secondary to separation from pod, stranding and inanition is also a potential cause of death.
“It was unfortunate that a marine mammal was found dead at Balayan Bay, since the bay is known to have pods of dolphin because of its rich marine biodiversity,” BFAR said in a statement.
The BFAR, in its mandate to protect and conserve our marine biodiversity, is continuously reminding locals, coastal residents and fisherfolks to report any information regarding the stranding of any marine mammals observed as well as unusual occurrence of aquatic wild life in their area.
