Item Metadata only Description of a new species of the genus Acropoma (Acropomatidae) from the Arafura Sea with a redescription of Acropoma leobergi Prokofiev 2018 and the first record of Acropoma boholensis Yamanoue and Matsuura 2002 from the South China SeaMakoto, Okamoto; Williams, Jeffrey T.; Carpenter, Kent; Santos, Mudjekeewis; Kimura, Seishi (Springer, 2020-01)A new species of the genus Acropoma, A. arafurensis sp. nov., is described based on two specimens (57.3–76.2 mm standard length: SL) collected from the Arafura Sea. The present species is distinguished from other congeners by a combination of the following characters: luminous gland U-shaped extending from throat to posterior tip of pectoral fin; luminous-gland length 29.5–32.0% SL; symphysis of lower jaw not sharply protruded; proximal radial of first anal-fin pterygiophore with concavity on anterior surface; anus situated closer to pelvic-fin insertion than to origin of anal fin; cycloid scales on lateral side of posterior half of body; vertical line on cheek absent; scales between first dorsal-fin base and lateral line 4; pectoral-fin rays 15; and gill rakers 20–21. Acropoma leobergi is redescribed based on 60 specimens (38.6–143.5 mm SL) from Taiwan, Philippines, and northern and west coast of Australia. Additionally, two specimens (94.9–103.1 mm SL) of A. boholensis collected from Luzon, Philippines, represent the first record of this species from the South China Sea.Item Metadata only Development and application of the fisheries vulnerability assessment tool (Fish Vool) to tuna and sardine sectors in the PhilippinesJacinto, Melchor R.; Songcuan, Al Jayson G.; Yip, Graceous Von; Santos, Mudjekeewis (Elsevier, 2015-01)Climate change studies in the Philippines are emerging fast, focusing on different fields of sciences. However, studies that address the fisheries sector remain insufficient. Here, we described a sector-based fisheries vulnerability assessment tool (Fish Vool) to evaluate the vulnerability of primary fishery commodities. Tool demonstration and validation were conducted in General Santos and Zamboanga City, which are the primary producers of tuna and sardine, respectively. Fish Vool revealed an overall medium vulnerability (low exposure, medium sensitivity, and low adaptive capacity) for both sectors. The vulnerability assessment of the tuna and sardine sectors emphasizes the potential of Fish Vool to assess climate change vulnerability for primary commodities and other fishery sectors.Item Open Access Hidden diversity in sardines: Genetic and morphological evidence for cryptic species in the goldstripe sardinella, Sardinella gibbosa (Bleeker, 1849)Thomas, Rey C.; Willette, Demian; Carpenter, Kent; Santos, Mudjekeewis (Public Library of Science, 2014-01-08)Cryptic species continue to be uncovered in many fish taxa, posing challenges for fisheries conservation and management. In Sardinella gibbosa, previous investigations revealed subtle intra-species variations, resulting in numerous synonyms and a controversial taxonomy for this sardine. Here, we tested for cryptic diversity within S. gibbosa using genetic data from two mitochondrial and one nuclear gene regions of 248 individuals of S. gibbosa, collected from eight locations across the Philippine archipelago. Deep genetic divergence and subsequent clustering was consistent across both mitochondrial and nuclear markers. Clade distribution is geographically limited: Clade 1 is widely distributed in the central Philippines, while Clade 2 is limited to the northernmost sampling site. In addition, morphometric analyses revealed a unique head shape that characterized each genetic clade. Hence, both genetic and morphological evidence strongly suggests a hidden diversity within this common and commercially-important sardine.Item Open Access New species of redbait from the Philippines (Teleostei, Emmelichthyidae, Emmelichthys)Girard, Matthew; Santos, Mudjekeewis; Bemis, Katherine (Pensoft Publishers, 2024-03-22)We describe a new species of redbait in the genus Emmelichthys collected from fish markets on Panay and Cebu islands in the Visayas region of the Philippines. The species is externally similar to E. struhsakeri but is diagnosable by two prominent fleshy papillae associated with the cleithrum and fewer pectoral-fin rays (18–19 vs. 19–21) and gill rakers (30–33 vs. 34–41). Additionally, mitochondrial DNA differentiates this taxon from other species of Emmelichthys. We generate mitochondrial genomes for two of the three type specimens and several other emmelichthyids to place the new taxon in a phylogenetic context. Analysis of the protein-coding mitochondrial loci calls into question the monophyly of two emmelichthyid genera (Emmelichthys and Erythrocles) and highlights the need for subsequent analyses targeting the intrarelationships of the Emmelichthyidae.
