UPM-VCC-JSPS Workshop on Zooplankton Biodiversity in Southeast Asia

Institute of Bioscience, Universiti Putra Malaysia

Serdang, Selangor, Malaysia

27-29 November, 2006

Summary Report (Final Version: 061212)

The entitled workshop was held on 27-29 November 2006 at the Institute of Bioscience of the Universiti Putra Malaysia with support of UPM, VCC and JSPS and convened by Fatimah MD Yusoff (UPM) and Othman BH Ross (UKM).

The first day was devoted to review of the project’s accomplishments to date.

Following the opening address by F.M.D. Yusoff, the overall activity of the project was reviewed by S. Nishida (ORI, Japan) as follows. The training courses on methods of zooplankton ecology and identification have been successfully held as originally planned in four countries: Thailand (2003), Philippines (2004), Vietnam (2005) and Malaysia (2006). The discovery of new species and their publication have also been accomplished with high pace as expected, with a total of 18 papers describing1 new family, 4 new genera, and 28 new species of crustaceans from Asian waters published during 2005 and 2006. The number of papers published in refereed journals in the same term totals > 40 including those on taxonomy, distributional ecology, community structure, production ecology, molecular genetics, pollution, and toxicology. The whole project (Coastal Marine Science) received the mid-term evaluation by JSPS and was scored A, with expectations for future improvement in outreach activities, collaboration among sub-projects, and contribution from SE Asian scientists to publications. The Census of Marine Zooplankton (CMarZ) cooperating with the present project had its Second Steering Member Meeting at ORI, Japan, during 6-8 November 2006, wherein the contribution from the present project was reported and future cooperation was agreed with respect, in particular, to SE Asian activities on the field research, database establishment, and training courses and outreach. The following challenges were identified to be discussed on day 2: (1) publication of identification manual and photographic album, (2) geographic survey of zooplankton deformities as indicator of environmental health, (3) more function-oriented (e.g. biomass structure, production, food-web), advanced collaborative researches on zooplankton biodiversity.

The research activities of the co-operating countries to date were reported by the members of Malaysia (Yusoff and Ross), the Philippines (L.V. Castillo), Vietnam (Nguyen Thi Thu and Nguyen Cho), and Indonesia (I.F.M. Rumengan and Mulyadi), followed by reports on the activities of Japanese members (H. Sekiguchi, S. Sawamoto, S. Nishida, N. Iwasaki, and J. Nishikawa). The topics of particular interest included those on the trophodynamics of coral-reef ecosystem and species diversity of coastal waters in Malaysia, the researches on giant-jellyfish fisheries and recruitment of palinurid lobsters in Vietnam, distribution of epipelagic zooplankton in the Sulu Sea in the Philippines, Hg contamination study in Sulawesi, Indonesia, and copepod and mysid diversity in SE Asia. The oil-spill accident in last August in the Philippines and the present circumstance with the post-accident monitoring were reported by Castillo on behalf of W. L. Campos, the leader of the biophysical aspects of the monitoring.

In the morning of the second day, the planning for 2007-2010 was discussed on the basis of the review on the first day, as follows.

1. Training Course

1) The planning for the training course in 2007 was introduced by Mulyadi and agreed with the following points:

・Dates and duration: Middle Nov. or late Oct. (e.g. 20-30)

・Venue: Div. Zoology, Cibinong

・Field sampling: Jakarta Bay (1hr from Cibinong), boats available by rental.

2) The planning for the training course from 2008 to 2010 was discussed as follows. Advanced courses including practical techniques of, e.g., photography, TEM/SEM, molecular genetics, might be possible candidates. However, having such advanced courses with similar number of trainees as in the previous courses may not be practical, given that need for such techniques still lags behind that of more basic techniques, such as morphological identification. Techniques on more ecological aspects, such as biomass estimates (at carbon basis), chlorophyll measurements, and physiology (oxygen consumption, etc.) are other options. However, these techniques are readily available in published books/manuals (e.g. ICES Manual), commonly educated in many university courses, and require special laboratory facilities out of scope of the project. In summary, it will be most practical and efficient to have future courses as semi-open workshops on advanced techniques and laboratory observation on particular topics of the project, with the JSPS members plus some outside scientists as participants. The topical techniques may include: molecular genetics, TEM/SEM techniques, photography, stable-isotope ratios, identification of taxonomic groups not yet covered in the previous courses, and field sampling to more wide coverage of coastal waters of particular countries. All these should be discussed further.

2. Species list

1) It was agreed that each member(s) submit a revised list of zooplankton species of SE Asia by the end of November 2007 as assigned below.

In the afternoon of the second day a tour was held in the Institute of Bioscience, around the UPM campus and to the Putra Jaya Area. In the rest of the second day and the third day the members made detailed examination of the samples (copepods, gelatinous plankton, and mysids) collected during the Training Course or brought by the members from different countries. A total of 40 copepod species were identified from the Malaysian waters, including 3 species (belonging to the genera Oithona, Labidocera, and Pseudodiaptomus) suspected to be new to science and more than 10 species new to the fauna of the Straits of Malacca. Analysis of the mysids and gelatinous plankton are now in progress and will be reported later. The original samples collected during the Training Course are deposited at the Institute of Bioscience, UPM, with accompanying metadata of sampling.
