“…The regional differences in the species composition of tidepool fish assemblages are consistent with other studies on shallow water and subtidal fishes (e.g. Shao et al, 2002;Hsiao et al, 2011). Interestingly, pairs of species within the same genera were occurring in parallel in subtropical and tropical Taiwan.…”

“…The island of Taiwan is located at the northern point of a marine biodiversity hotspot in the western Pacific Ocean (Chen and Shashank, 2009) and is divided into tropical and subtropical climatic regions (south and north). Subtidal reefs in northern and southern Taiwan have distinctly different species compositions (Shao et al, 2002;Hsiao et al, 2011), and these differences extend beyond Taiwan to other nearby countries (i.e. Japan and the Philippines, Liu et al, 2008;Chen and Shashank, 2009).…”

Spatial and temporal variations in the species composition of assemblages are common in many marine organisms, including fishes. Variations in the fish species composition of subtidal coral reefs have been well documented, however much less is known about such differences for intertidal fish assemblages. This is surprising, given that intertidal fishes are more vulnerable to terrestrial human disturbances. It is critical to evaluate the ecology and biology of intertidal fishes before they are severely impacted by coastal development, especially in developing countries such as those in the tropical western Pacific region where coastal development is rapidly increasing. In this study, we investigated the species composition, abundance, biomass and species number (richness) for intertidal fish assemblages in subtropical (northern) and tropical (southern) Taiwan across four seasons by collecting fishes from tidepools using clove oil. We also examined the gut contents of collected fishes to identify their trophic functional groups in order to investigate regional and seasonal variations for different trophic groups. We found significant differences in the species composition of tidepool fish assemblages between subtropical and tropical Taiwan. Bathygobius fuscus, Abudefduf vaigiensis and Istiblennius dussumieri were dominant species in subtropical Taiwan, whereas Bathygobius coalitus, Abudefduf septemfasciatus and Istiblennius lineatus were dominant in tropical Taiwan. Other species such as Bathygobius cocosensis, Abudefduf sordidus and Istiblennius edentulus were common in both regions. For trophic groups, omnivores and detritivores had or showed trends towards higher species numbers and abundances in the subtropical region, whereas herbivores, planktivores and general carnivores had or showed trends towards higher species numbers and biomass in the tropical region. Overall, many intertidal fish species and trophic groups showed differences in abundance, biomass and species number between subtropical and tropical Taiwan. Further studies on large scale geographical gradients in trophic groups and species compositions in the Indo-west Pacific region are encouraged to assist with ecosystem monitoring and assessment.

“…Taenioides anguillaris is known to have head length longer than the pelvic-fin posterior end to anus (P-A) length (e.g., Shen and Wu 2011). However, Koreeda and Motomura (2021) and the presently reported study found that T. anguillaris and T. snyderi shared that character, and consequently the record of T. anguillaris in Taiwan cannot be confirmed, pending examination of additional specimens.…”

Four gobiid specimens collected from the western coast of Taiwan were identified as Taenioides snyderi Jordan et Hubbs, 1925, being characterized by 51–55 (total) dorsal-fin rays, 44–46 (total) anal-fin rays, 17–19 pectoral-fin rays, 10 + 21 = 31 vertebrae, 3 paired barbels on the chin surface, the pelvic-fin base fused by membrane to the abdomen, and the pattern of the dermal folds with sensory papillae on the head and body. Taenioides snyderi has been recorded to date only from Japanese waters, although the likelihood of a wider distribution has been suggested by molecular analysis. This study represents the first specimen-based records of the species outside Japan, with data adding to our knowledge of a poorly known fish group.

“…Although only at the family level, the high numbers of Sciaenidae, Gobiidae, and Soleidae were roughly similar to the fish composition found in modern western Taiwan (Kuo and Shao 1999;Shao et al 2002;Shao 2021), suggesting closely related environments. On the basis of a few otoliths from the same area, Lin (2010b) first interpreted the palaeoenvironment as being reflective of a shallow coastal sea.…”

“…At generic level, however, the sciaenid composition in Shulin is distinct. The modern fish fauna of western Taiwan includes large numbers of small Johnius and Pennahia (Shao et al 2002), both of which are absent in Shulin. Otoliths of Johnius are known from the Pliocene of Japan (Ohe 1976(Ohe , 1981, and those of Pennahia are known from the Pleistocene (Ohe 1976).…”

Knowledge of Neogene fish diversity in Taiwan is extremely limited. In this paper, we present a collection of 1716 fish otoliths recovered from the late Miocene Tapu Formation. The abundance and density of otoliths vary across the sites. Although the preservation of samples is considerably limited, our sample coverage is sufficient and reveals the presence of at least 34 otolith-based taxa belonging to 13 families. Four new species are introduced: Larimichthys koae sp. nov., Nibea chaoi sp. nov., Taosciaena jiangi sp. nov., and T. hui sp. nov. Among the earliest fossil records, this collection features a remarkable abundance of Larimichthys spp. The assemblage is dominated by otoliths of Sciaenidae, Gobiidae and Soleidae, and it is indicative of a coastal shallow-water palaeoenvironment with muddy to sandy bottoms, perhaps adjacent to a river mouth. We hypothesise that the differences in the taxonomic composition between the fossil assemblage and modern fauna are mainly chronological and evolutionary, and only a moderate turnover of certain lineages has occurred since the Miocene. Our study provides a unique 'window' to a rarely visited fossil fish community that exclusively documented by fossil otolith data, and reveals a past coastal fish diversity that otherwise could not be recognised.
