“…The best conservation option for populations of G . aureus that are carnivorous [ 20 ], genetically diverged, and geographically separated is to protect them in their native habitats [ 119 ]. Conservation efforts must also address other threats like pollution, habitat fragmentation or loss, and introduction of invasive species.…”

The golden flathead goby Glossogobius aureus is a native species in the Philippines, Australia, Japan, Taiwan, and many other countries in Asia. In the Philippines, it is an important food fish as it is commonly caught in major lakes. In this study, a total of 307 specimens morphologically identified as G. aureus were sampled from nine major lakes in the Philippines and were sequenced for their mitochondrial cytochrome b (cyt b) gene. Two hundred sixty of the 307 cyt b sequences had sequence similarities of ≥ 99% with G. aureus reference sequence in GenBank, while the remaining 47 (all from Lake Lanao) had sequence similarities of only 95% and were thus designated as Glossogobius cf. aureus and treated as a separate population. The sequences were then analyzed to examine the pattern of genetic diversity, relatedness, divergence, and demographic history among native and translocated populations of the species. Twenty-nine haplotypes were recovered, of which four haplotypes were shared among three to seven populations. Only one haplotype each was found in the native population in Lake Buhi and translocated population in Lake Paoay. Low haplotype and low nucleotide diversities were found for the populations in Laguna de Bay, Lanao, Bato, Buhi, Paoay, and Sebu lakes, which indicate founder event for the introduced populations in Lanao, Paoay, and Sebu lakes and recent genetic bottleneck for the native populations in Laguna de Bay, Bato, and Buhi. In contrast, high haplotype but low nucleotide diversities were found for the native populations of Taal, Naujan, and Buluan lakes, signifying a recent bottleneck followed by population expansion. Pairwise FST values showed generally large (FST = 0.168–0.249) to very large (FST = 0.302–1.000) genetic divergence between populations except between Laguna de Bay and Lake Bato, Laguna de Bay and Lake Buhi, and Lake Bato and Lake Buhi populations, which showed nonsignificant genetic differentiation. Lake Buluan and Lake Sebu populations showed moderate genetic differentiation (FST = 0.098). Neutrality tests showed significant negative Tajima’s D and Fu’s FS values only for the population from Laguna de Bay, which suggests that the population is undergoing expansion. These results are important for establishing scientifically sound strategies for effective conservation and sustainable exploitation of G. aureus in the Philippines.

“…in the digestive tract of G. aureus may be attributed to the life history patterns of species in the genus Azygia with 2 hosts: a snail as intermediate host and a fish as definitive host (Sillman, 1962). In turn, G. aureus and other species of Glossogobius which are carnivorous, rely primarily on small fishes (Hossain et al, 2016; Phan et al, 2023) then transfer the worms to the gut of gobies.…”

One hundred eighty-three individuals of Glossogobius aureus, native to Lake Taal, Philippines, were collected in 2021-2022. Of these, 4 endohelminths were found and identified: Andracantha gravida (Acanthocephala: Polymorphidae), Schyzocotyle acheilognathi (Platyhelminthes: Bothriocephalidae), Azygia sp. (Platyhelminthes: Azygiidae), and Opegaster minima (Platyhelminthes: Opecoelidae). These helminths represent new host records for G. aureus and provide novel contributions to the recent Philippine parasite biodiversity listing. Among these 4 helminths, Azygia sp. was the most prevalent, had the highest percent dominance and mean intensity, and had a broader range followed by S. acheilognathi, A. gravida, and O. minima, respectively. These findings highlight the need to further explore Lake Taal's parasitofauna, especially with regard to the invasion of S. acheilognathi, and the transmission specificity of O. minima, which can be utilized as a keystone parasite biomarker and in return aid in the management and conservation efforts in Lake Taal.
