Abstract

Mabini, Batangas known for its diving attractions and diverse marine life, highlights the potential of its macroalgae as bioindicators for marine conservation. This paper aimed to establish baseline information on macroalgae distribution in Mabini, Batangas. The population of macroalgae were assessed through a single evaluation at each site (Anilao Proper, San Jose, Bulacan), using line transect-quadrat method. There transects were laid as replicates at each site between September – October (Southwest monsoon). The physicochemical characteristics (pH, salinity, dissolved oxygen, temperature, nitrate, and phosphate) were measured using a multi-parameter probe and laboratory analysis to assess correlation with macroalgae abundance through Principal Component Analysis (PCA). Results showed that in terms of seaweed composition, Bulacan, having the most expansive rocky substratum, and least exposure to the southwest moon, has higher species richness (45) than San Jose (22) and Anilao Proper (18). Bulacan was the most diverse (3.11), followed by Anilao Proper (2.13) and San Jose (1.97). Notably, Amphiroa foliacea (28.62%), Actinotrichia fragilis (15.60%), and Ceratodictyon spongiosum (8.80%) dominated in Anilao Proper. In San Jose, A. fragilissima (9.66), Halimeda tuna (5.22), Gracilaria edulis (7.81), Halimeda cylindracea (7.55), Padina sp. (9.43), and Ulva reticulata (6.43) dominated. Substrate condition in all sites varied from sandy, coralline and rocky. Aggregated results of seaweed composition across all sites revealed Chlorophyceae as the most speciose class. Physicochemical conditions exhibited minimal variation across sites. PCA revealed positive negative correlation between abundance of seaweed species and physicochemical parameters.

In celebration of Verde Island Passage Center for Oceanographic Research and Aquatic Life Sciences’ (VIP CORALS’) 1^st Anniversary on February 14, 2019, the center conducted a seminar series entitled “Waves and Ripples at the Heart of the Coral Triangle”. The event tackled about the importance of the different marine-related topics by invited speakers from different institutions.

The seminar was commenced by Dr. Tirso A. Ronquillo, Batangas State University’s President, with his welcoming remarks who conveyed his acknowledgement of the existence of the center in protecting and researching in the Verde Island passage. It was followed by Dr. Renan U. Bobiles from Bicol University, who discussed about the importance of marine protected areas. Dr. Emma Ballad, from BFAR Region II, incorporated the connection between socio-environmental economics and the marine protected areas in the Philippines. Dr. Vanessa Baria-Rodriguez, from the University of the Philippines Marine Science Institute (UP MSI), highlighted the significance of coral reefs to the oceans, its inhabitants and even to us, humans. While Dr. Wilfred Santianez from the same University emphasized on seaweed farming ecological and economic value. Southern Cross University researcher, Dr. Dexter Dela Cruz’s main discussion was concerned on coral reef restoration and some of its consequences. SEA-VIP personnel, Mr. Joal Ascalon, share up some of their institution’s work-related activities in engaging citizens to the science world and the importance of their contribution in battling climate change. Meanwhile, Ms. Talna de la Cruz, from UP MSI, tackled the input of science and communication. Moreover, National Museum of the Philippines’ staff,  Mr. Nero Burner, opened his discussion on maritime archeology.

The event was then concluded by Dr. Jayvee A. Saco, Center Head of VIP CORALS, with his warm message towards the invited speakers as well as to the students, faculty and others that have attended to the said event.

The VIP CORALS expands its network with a meeting with Dr. Shan He (person in middle wearing blue), Associate Dean of College of Food and Pharmaceutical Sciences, Ningbo University, Ningbo, China last February 11, 2019. He presented the different colleges in Ningbo University; programs offered, international collaboration, funding and its connection with the Philippines.  He also discussed the importance of the scientific diving training, different marine drug discovery and marine healthcare products where he is affiliated. Lastly, he offered future collaborations between Ningbo University and Batangas State University through collaborative agreements, students exchange and recruitment, marine drug discovery and healthy food development and exploring twilight zone resource by scientific deep diving.
