bt.zhang.2022b.RdDetermining the movement and migration patterns of fish between different environments is crucial for understanding the distribution of fish populations and the ecological mechanisms underlying their spatial dynamics. This study is the first to employ otolith Sr:Ca and Ba:Ca profiles to elucidate habitat use by the commercially valuable estuarine species Eleutheronema rhadinum.
bt.zhang.2022bThe data frame 89,170 × 8 contains the following columns:
| fish_id | integer | fish identifier |
| distance | numeric | distance from otolith core (um) |
| oto_sr_ca | numeric | otolith sr:ca (mmol/mol) |
| oto_ba_ca | numeric | otolith ba:ca (mmol/mol) x10^2 |
| fork_length | numeric | fork length (cm) |
| weight | numeric | body weight (kg) |
| location | character | location of capture |
| region | character | region of capture |
This dataset contains 22 otolith microchemistry (Sr/Ca and Ba/Ca) profiles of East Asian fourfinger threadfin Eleutheronema rhadinum from the East China Sea and South China Sea, caught off China in October to December of 2019.
Instrument: LA-ICP-MS (laser ablation-inductively coupled plasma mass spectrometry)
Beam diameter: 20um
Scan speed: 5um/s
Reference materials: NIST-610,NIST-612 (National Institutes of Standards and Technology glass standard)
