地理涵蓋範圍

Description: We downloaded the Landsat8 satellite image on 18 September 2022 and drew the investigation scope by using the ArcGIS 10.7 software. Our survey covered central western areas of Taiwan Island, such as inshore and offshore coastal waters. Coordinates samplings site: Changhwa: 24.1579N, 120.3837E; Miaoli: 24.6179E, 120.6221E; and Yunlin: 23.7029N; 120.1022E.

分類群涵蓋範圍

Six species of Johnius were recorded in the dataset based on site collection and Johnius species composition, namely Bearded croaker, Johnius amblycephalus (Bleeker, 1855) - Bearded croaker, Belanger's croaker, J. belangerii (Cuvier, 1830) Belanger's croaker, Sharpnose hammer croaker, J. borneensis (Bleeker, 1850), Sharpnose hammer croaker, croaker, J. distinctus (Tanaka, 1916), Distinct's croaker, Taiwan's croaker, J. taiwanensis Chao et al., 2019, Taiwan's croaker, and Trewavas croaker, J. trewavasae Sasaki, 1992, Trewavas croaker. Only one sole Johnius species, J. grypotus Sasaki, 1990, described by Yu and Shen (1987) occurrences in Keelung, northern Taiwan, and resurrected by Sasaki (1990), was not found in this study. The most abundant species in the dataset were J. belangerii, J. distinctus, and J. taiwanensis (23.2%, 29.7%, and 30.4%). A photograph of sample material of Johnius species was cited by Hanafi et al. (2023b). Comparison data with Shao et al. (2012) collection sample are also provided, as comprehensive information on Johnius spatial distribution stretching from northern to southern western Taiwanese coastal waters was integrated into the present study. A finding of the present study was the occurrence of J. trewavasae in Miaoli and Changhwa, which Shao et al. (2012) did not collect in their sampling survey. In addition, the collection data did not acquire any J. grypotus samples occurrences in Taiwanese coastal waters during the sampling survey series.

計畫資料

Johnius are short migratory coastal species that travel less than 100-200 meters between estuaries and neritic water during their life cycle (Mok et al. 2009). Fricke et al. (2023) identified 35 legitimate Johnius species found in the Indo-West Pacific area, and classified them into two subgenera: Johnius (Johnius) and Johnius (Johnieops), the latter distinguished by a row of larger teeth on the lower jaw (Lal Mohan 1975). Among the Indo-West Pacific Sciaenidae, Johnius is the biggest and most taxonomically perplexing genus. Moreover, Johnius has remarkable diversity and is a global species, the monophyly of which has been established (Trewavas 1977, Lo et al. 2017, Lo et al. 2015). In Taiwan and Southeast Asia particularly, several studies have been conducted on the reproduction ecology and biological organism of Johnius (Lin et al. 2007, Zhang et al. 2019, Mok et al. 2009, jan et al., 2006, Jan et al., 2010), owing to the significant accessibility of the dispersal and migration between spawning sites. Nonetheless, understanding of their abundance, diversity, and ecological function is still limited in this region.

取樣方法

The sampling design for collecting bottom trawl harvest from coastal waters around central western Taiwan is shown. The abbreviations of locality names of the sampling sites are outlined below. Several series of extensive monthly samples collected from Miaoli, Changhwa, and Yunlin were analyzed starting in 2009, followed by the Yunlin collection from 2012-2016, and Miaoli fish landing ports in north-western Taiwan waters between March 2019 and March 2020. The fresh fish samples were used as identification species by morphological characters with specimen vouchers.

方法步驟描述:

1. Data collection. The integration of Johnius distributional data started in 2009 to 2010 in Changhwa county, while data from 2012 to 2016 were acquired from the master’s dissertation of Liou (2016). Data from both were collected seasonally by trawling method. Meanwhile, from March 2019 to March 2020, the samples collected in Miaoli were collected monthly by either trawling in the coastal waters of Taiwan or from fish markets. A total of 2,566 Johnius samples were used to investigate their spatial distribution in Taiwanese waters. After the sample collections had been sorted, all the specimens were identified to the species level (Chao et al. 2019, Hanafi et al. 2023), and their length (in mm) and weight (in g) were measured.
2. Open data preparation: We converted the occurrence data into Darwin Core Archive standard in Google Sheets, an online spreadsheet tool, using the Darwin Core Archive Assistant Add-on (Salim and Saraiva 2020). The data were then made available on the IPT TaiBIF and GBIF for the public to access.
