“…The 10 most prevalent families in the latter (Pomacentridae, Labridae, Lutjanidae, Chaetodontidae, Epinephelidae, Carangidae, Acanthuridae, Gobiidae, Scaridae, and Apogonidae) closely align with those in this study, with the exception of Muraenidae and Nemipteridae, which hold higher proportions in our findings. Balisco et al 64 reported a higher number of nemipterids (24 vs. 16 in this study), while the count of muraenid species is lower (11 vs. 19). The predictable underestimation of reclusive taxa like moray eels is a recognized limitation of using UVC to assess fish diversity 64 .…”

“…Balisco et al 64 reported a higher number of nemipterids (24 vs. 16 in this study), while the count of muraenid species is lower (11 vs. 19). The predictable underestimation of reclusive taxa like moray eels is a recognized limitation of using UVC to assess fish diversity 64 . On the other hand, moray eels are an important component of popular local dishes and have been regarded as one of the main targets of commercial fisheries in the Central Visayas region 65 , resulting in more species obtainable from fish markets.…”

“…Moreover, six families (Atherionidae, Bembropidae, Cynoglossidae, Myctophidae, Sillaginidae, and Zenarchopteridae) were absent from Bemis et al 5 , demonstrating the significant contribution of this study in expanding the barcode reference library for Philippine marine fishes. Likewise, the Cebu market survey and a recent fish checklist in Palawan, based on underwater visual census (UVC) in coral reefs 64 , show a very similar composition of speciose families. The 10 most prevalent families in the latter (Pomacentridae, Labridae, Lutjanidae, Chaetodontidae, Epinephelidae, Carangidae, Acanthuridae, Gobiidae, Scaridae, and Apogonidae) closely align with those in this study, with the exception of Muraenidae and Nemipteridae, which hold higher proportions in our findings.…”

“…We followed the taxonomic classification by Betancur-R et al 29 for the order level, and by Eschmeyer's Catalog of Fishes 72 for the family, genus, and species levels. The final species list was cross-referenced with records from FishBase 73 , Eschmeyer's Catalog of Fishes 72 , Balisco et al 64 , and Bemis et al . 5 to ascertain the number of newly recorded species in the Philippines.…”

A morphology-based barcoding library of market teleost fishes (Teleostei) in Cebu is built based on cytochrome c oxidase subunit I (COI) sequences and voucher specimens which aimed to establish a reliable reference of frequently traded fishes in the province, a biodiversity hotspot at the center of the Philippine archipelago. A total of 1721 specimens were collected from 18 fish markets and landing sites around the province, in which 538 specimens were sequenced belonging to 393 species from 229 genera, 86 families, and 37 orders. Most speciose families are coral reef or reef-related shallow-water species. Twelve species from 11 families are newly recorded in the Philippine waters, among which 7 species are deep-sea inhabitants, while 3 species have expanded their distribution range. Only 20 taxa could not be identified to the species level due to the difficulty in morphological examinations, absence of matched reference sequences in online databases, and/or problematic species awaiting further studies. This first comprehensive DNA barcoding survey of Cebu fishes can facilitate further taxonomic research as well as the conservation and management of fisheries in the Philippines.

“…FMAs cover an estimated combined area of 4,640 km 2 (about 21% of the country's total reef area); diversity is comparable with that of the Coral Triangle and higher than that of the rest of the SCS (DENR-BMB 2020; Quimpo et al 2019citing Dorman et al 2015Juinio-Meñez 2015;Licuanan et al 2021;Quimpo et al 2019citing Huang et al 2015. A recent report identified 1,056 marine fishes in FMA 5, comprising 32 elasmobranchs and 1,024 bony fishes in two classes, 42 orders, 115 families, and 366 genera (Balisco et al 2023).

Geopolitical issues pose a challenge to the holistic management of fisheries and associated ecosystems in two Philippine fisheries management areas (FMAs 5&6) encompassing the West Philippine Sea. One way to allay these issues is through a common values approach based on heritage. This paper presents evidence of the heritage value of FMAs 5&6 that could be integrated into an ecosystem approach to fisheries management to manage conflicts. This presupposes a common understanding of their heritage value and the fundamental principle that sustaining this value is good—in fact, essential—for everyone and our planet. Heritage value is assessed as a composite and dynamic unity of human gains and investments in the ecological value, economic value, and value to society of ecosystem services, which create cultural significance and socioeconomic worth for communities and peoples. Ecological value is assessed by way of selected indications of the ecosystem services of the two FMAs; economic value is assessed using published estimates of the monetizable and nonmonetizable value of these services; and value to society is evaluated based on influences on cultural identities, ways of life, and amenities in surrounding lands and contiguous waters. The values are highly significant and beneficial not only to Filipinos but also to others around the South China Sea and beyond. However, the ecosystem services underlying these values—and users’ access to them—are at risk. They need to be protected from climatic and anthropogenic threats, including illegal, unreported, and unregulated fishing, pollution, coastline modifications, island building, and violations of the United Nations Convention on the Law of the Sea provisions on safeguarding the marine environment and fishers’ safety.

An annotated checklist of 67 species of sharks, rays, and chimaeras (Chondrichthyes) confirmed to be present in Palawan waters was described based on (1) market visits in Puerto Princesa, Aborlan, Brookes Point, and Roxas between October 2021 and March 2022; (2) contributory citizen science soliciting photographs and video footage validated by the authors; and (3) review of various ichthyologic types of research in Palawan that include museum collection records, taxonomic papers, results of DNA analysis, institutional project reports, and related literature, particularly on the occurrence and distributional range of the species. An additional 24 species were placed on the unconfirmed list due to insufficient evidence collected and thus required further investigation. The Province of Palawan exercises environmental jurisdiction over its surrounding marine areas under Republic Act No. 7611, known as the Strategic Environmental Plan for Palawan, with the Palawan Council for Sustainable Development (PCSD), as its regulatory, enforcement, and policy-making authority. In response to the Wildlife Act (Republic Act 9147), the PCSD drafted Resolution 15-521(s. 2015), which updated the list of terrestrial and marine wildlife species in Palawan for protection and management and included only 15 shark and ray species. This paper provides an updated list of Palawan Chondrichthyes (with notes on the conservation status based on the IUCN Global Red List Assessment), suggests a prescriptive approach to enhancing conservation policies in the province, and addresses some critical issues of conservation and management of the Philippine sharks and related species, in particular, and the Philippine fisheries in general.
