Scientists Support the Closed Season for Tawilis from March to April

Dr. Francis Magbanua, President of the Philippine Society for Freshwater Science (PSFS) stated their support regarding the declaration of the Tawilis as an endangered species and supports the ordinance issued by the Protected Area Management Board (PAMB) to implement the closed season of Taal Lake during March to April, including the implementation of a proper mesh size and establishment of sanctuaries.
 
Dr. Magbanua also emphasized the need for enforcement in the area. He reminded that not only it is a job for the DENR and Bureau of Fisheries and Aquatic Resources (BFAR), but also for the Local Government Units and other stakeholders. He also called for the need for continuous monitoring of the Tawilis and the lake to see if the implementation is successful.
 
During the Tawilis Summit held on February 19, with the theme: “4TS: Talakayan Tungkol sa Tawilis at Taal”, the stakeholders of Taal Volcano Protected Landscape gathered at the University of Sto. Tomas in España, Manila. The whole day event targeted to inform the public about the rationale and other related researches about the Sardinella Tawilis and Taal Lake. The summit provided the venue for stakeholders to discuss the current status and future management prescriptions to conserve the Tawilis population. Tawilis is the only freshwater sardine and can only be found in Taal Lake. According to a study of Reproductive Biology of the Tawilis done by Associate Professor Alicia Pagulayan, “Sardinella Tawilis breeds the whole year round with peak spawning activities from December to March and a less pronounced spawning during the months of July to October”.
 
A study about the Tawilis fishery reserves and spawning grounds were discussed by Dr. Ma. Theresa Mutia. Both studies done by Prof. Pagulayan and Dr. Mutia showed the same results on the most active spawning months, which is March to April.
 
Dr. Mudjekeewis Santos, explained the assessment of the International Union for Conservation of Nature (IUCN) of the Tawilis as an endangered species. Dr. Santos disclosed that the goal of the IUCN is to “provide knowledge and tools that enable human progress, economic development and nature conservation to take place together.” One tool that the IUCN provides is the Red List of Threatened Species. The goal of the Red List is “to provide information and analyses on the status, trends and threats to species in order to inform and catalyze action for biodiversity conservation”.
 
Santos also said that as early as 2011, there is already a paper published depicting the depletion of the Tawilis. He said that every time an animal goes endangered, “we did not do enough and we are failing”.
 
Threats for the Tawilis include overfishing, pollution, invasive fish species, fish kills, habitat modification, invasive planktons, climate change-related impacts and unsustainable fishing practice.
 
On the other hand, the home of the Tawilis, Taal Lake, was discussed by Dr. Rey Donne Papa. He said that it is a tropical caldera lake, with an active Volcano and has intensive Aquaculture with very little scientific data. Dr. Papa also said that the changes and improvements in Taxonomy of the lake, the introduced and invasive species, the impact of Aquaculture and climate change makes the Taal Lake worthy to be studied again and again.
 
Atty. Maria Paz Luna, Regional Executive Director of Department of Natural Resources, shared that the Taal Volcano Protected Landscape (TVPL) Management Plan has undergone public consultations, a task force has been created, a revised plan has been drafted and has an active Protected Area Management Board (PAMB). Despite these, there are challenges due to increasing population and the absence of sewerage and septage systems in the Municipalities and Cities surrounding it and the problem on solid waste management. To add to that, there are illegal discharges of livestock farms that drain to the lake. She continued on discussing the penalties and fines under the Expanded National Integrated Protected Areas System (E-NIPAS) Act which may be served to violators. However, she also highlighted that because of the uniqueness and issues within TVPL, a law needs to be crafted to address these challenges. She also stressed that Tawilis harvested by fisherfolk for subsistence may be allowed during the closed season.

The Tawilis Closed Season will be implemented from March to April this year and the years after. The DENR is urging the public to report establishments who will be selling Tawilis in large or commercial scale, during the closed season.

DENR CALABARZON celebrated the World Mangrove Day

Mangrove calatagan 

          In line with the celebration of World Mangrove Day on June 26, 2019, the DENR CALABARZON Conservation and Development Division organized a mangrove tree planting activity, conducted at Barangay Talisay, Calatagan, Batangas.

         The mangrove tree planting activity was participated in by 60 volunteers from the DENR CALABARZON, CENRO Calaca, Batangas, Ecosystems Research and Development Bureau (ERDB), Local Government Unit of Brgy. Talisay, and the Samahan ng Nagkakaisang Mangingisda sa Barangay Talisay (SNMBT) People’s Organization. A total of 1,200 propagules of Bakawang Lalaki and Bakawang Bato species were planted.

           According to Ms. Violy Gulapo, Senior Science Research Specialist from the ERDB, a total number of 500,000 hectares of mangrove forest in 1918, has drastically gone down to only 117,000 hectares in 1995. In 2011, it has gradually increased to 257,362 hectares which may be attributed to coastal rehabilitation programs implemented by government, NGO and communities. She added that three main functions of the Mangrove Ecosystems are for fishery production, for environmental protection, and as a carbon sink. She commended the Agency for conducting Mangrove rehabilitation programs but she reminded that people conducting planting activities should have enough knowledge in proper zonation of the mangrove. She emphasized that we have to monitor the success rate of every planting activity.

           Mr. Rodrigo de Jesus, president of the SNMBT, disclosed that their organization does regular mangrove planting activities since 2007.
