Ichthyology on the 2011 Philippine Biodiversity Expedition

M/V DA-BFARIchthyology staff participated in several ventures as part of the Academy's 2011 expedition to the Philippines.  Senior Collections Manager David Catania dove in shallow waters off the southern coast of Luzon Island, along with other scientists from the Academy and the Philippines.  They also made excursions to Taal Lake in search of a freshwater sardine and new species of freshwater gobies.  Finally, the Department's Curator Emeritus, Tomio Iwamoto, and Department of Aquatic Biology Curator, John McCosker, joined Dave and other marine scientists on the vessel M/V DA-BFAR (pictured) to trawl in the deep waters around Lubang Island.  Among other things, they found a new species of snake eel, Myrichthys paleracio, described by Dr. McCosker.  All told, Academy and Philippine scientists discovered over 300 species that are likely new to science.

We are finally here, and the most important piece of equipment onboard, the compressor to fill our scuba tanks, breaks down. It is unfortunate, and we will certainly be more prepared next time. But there are still some things we can do just snorkelling. Large schools of fish were a common sight. And with that […]
The Parcel Manuel Luiz is a marine State Park, and it is truly amazing how different it is to dive in a protected area. During our first dive we saw many large fish, usually not seen in areas frequented by fishermen. Our first dive also brought a welcome surprise. During my last trip to the […]
