This dataset, derived from two OR3 research vessel surveys conducted at seven nearshore sites off the western coast of Taiwan in May (late spring) and November (late autumn) 2019, offers a record of small demersal fish assemblages. The data includes 1,809 fish, covering 37 families, 67 genera, and 99 taxa. While the number of fish species recorded in May (26 families, 47 genera, 65 taxa) and November (31 families, 46 genera, 63 taxa) are similar, there is a significant difference in the fish composition. Thirty-six species, belonging to 19 families and 30 genera, were exclusively observed in May, whereas 34 species from 25 families and 28 genera were only recorded in November.

The fish specimens caught by each trawl haul were immediately extracted from the catches, roughly classified by species and frozen at − 20°C on board. Subsequently, all fish specimens were transferred to the laboratory on land for taxonomic identification.
Two seasonal cruises, on 25th to 27th May (late spring) and 16th to 18th November (late autumn), 2019 were conducted at seven sites along the western coastal waters off Taiwan. From north to south, these sites were Wuchi (Wuqi) (WC) (24°15’N), Wanggong (WG) (23°59’N), Taisi (Taixi) (TS) (23°39’N), Chiku (Qigu) (CK) (23°09’N), Jiading (Qieding) (JD) (22°52’N), Linyuan (LY) (22°28’N), and Fangliao (FL) (22°18’N). These sites were chosen according to their topographic features and environmental conditions.
The surveys were conducted by R/V Ocean Researcher No.3 using a beam trawl (width 6 m, body length 8 m, body mesh 4.5 cm, and cod end mesh 2.5 cm) operating at a water depth of between 15 and 35 m, approximately 3 nautical miles off the coastline. At each site, two sampling locations were set at a water depth of ca.15 m and ca.25 m, respectively. In total, 27 trawling hauls were conducted . For each trawl haul, the beam trawl was deployed to touch the seafloor at the sampling site, with a towing speed of ca. 2 knots for a period of 30 min.
The identification of fish specimens was conducted to the lowest level of taxonomic hierarchy possible based on the following reference books of Shen et al. and Nakabo et al., and the fish databases of Froese and Pauly and Shao.
