“…It has already been documented that in fish with ctenoid scales, the occurrence of both cycloid and ctenoid scales in a given fish body region is possible because all ctenoid scales evolved from cycloid scales (Roberts, 1993). During the developmental process of these scales, cycloid scales found above the lateral line (here the normal scale of region ii) do not develop ctenii until they attain the first year of their lives but in some scales from above the head, cheek, and opercle, they developed ctenii late in life or not at all (Matondo, Torres, Gorospe, & Demayo, 2012). Therefore, variation in the scales from above the head region concerning the presence of ctenii is probably related to the development of those scales from above the head region.…”

The normal and lateral line scales from above the head and four flank regions were investigated in two goatfishes by using light microscopy to evaluate the microscopic characteristics of scale surface ornamentation from different body parts of these fishes and to add new morphological data for their discrimination. The body scales were removed and digital images captured with a Dino‐Lite digital camera connected to a Leica compound microscope. The presence of both transverse and longitudinal radii was a distinctive characteristic for the scales of studied goatfishes. The most distinctive features of the key scales discriminating the two goatfishes were the scale shape, the presence of irregular grooves in scale surface, the presence of transverse radii in the lateral fields, and the availability of lepidont at the anterior field. The lateral line scale ornamentations were almost similar in two species; however, the lateral line canal was branching in Parupeneus heptacanthus. Scale extension index indicated that in both species, the dimension of normal key scales tends to the right, while the dimension of lateral line scales tends to the left. This study accentuated that scales from different body regions may exhibit variation in surface ornamentations, that scale morphology could successfully be used to discriminate the examined goatfishes, and that the use of fish scale microscopy is an easy and relatively rapid method and does not require fish sacrifice. Since fish identification is essential for the conservation and management of species, the use of scale morphology to this purpose appears particularly promising.

“…(3) Fossil ctenoid scale possess significantly more RDS than their extant counterparts. The direction of the radii aligns with the flow, and a higher number of radii suggests that the fish may have increased swimming speed and greater scale flexibility [10,36,37]. Thus, the main body of this ctenoid scale likely possessed exceptional flexibility.…”

The study of morphological characteristics and growth information in fish scales is a crucial component of modern fishery biological research, while it has been less studied in fossil materials. This paper presents a detailed morphological description and growth analysis of a fossil ctenoid scale obtained from the Upper Cretaceous Campanian lacustrine deposits in northeastern China. The morphological features of this fossil scale are well-preserved and consistent with the structures found in ctenoid scales of extant fish species and display prominent ring ornamentation radiating outward from the central focus, with grooves intersecting the rings. A comparative analysis of the morphological characteristics between the fossil ctenoid scale and those well-studied extant fish Mugilidae allows us to explore the applicability of modern fishery biological research methods to the field of fossil scales. The scale length, scale width, the vertical distance from the focus to the apex of the scale, and the total number of radii have been measured. The age of the fish that possessed this ctenoid scale has been estimated by carefully counting the annuli, suggesting an age equal to or more than seven years. The distribution of growth rings on the scale potentially reflects the warm paleoclimatic condition and fish-friendly paleoenvironment prevalent during that period. This paper, moreover, serves as a notable application of fishery biological methods in the examination of fossil materials.

“…Although G . aureus is widely distributed in East and Southeast Asia and serves as an important food fish [ 11 ], the current knowledge about this species is limited to its feeding habits [ 20 ], scale shape [ 21 ], population biology [ 22 ], and reproductive traits [ 11 ]. To date, there are no studies yet on the genetic diversity and population genetic structure of G .…”

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.
