Young-of-the-year Baltic flounder otolith chemistry collection information from 2014 to 2017 at Baltic Sea sites in Sweden and Latvia.

Abstract:

Young-of-the-year (YOY) flounder were collected by beach seines at Baltic Sea sites in Sweden and Latvia. Fish were stored frozen until they were processed. This dataset is comprised of collection data information, which associates each individual fish with a particular collection date and location, provides fish length, etc. The corresponding chemistry data is found in the YOY chem dataset (https://www.bco-dmo.org/dataset/775428)

Description

Methods & Sampling

Young-of-the-year (YOY) flounder were collected by beach seines at Baltic Sea sites in Sweden and Latvia. Fish were stored frozen until they were processed. Processing consisted of measuring total lengths and extracting their sagittal otoliths. The otoliths were cleaned, dried, mounted on glass slides, and then polished to expose the core. Chemical analyses were conducted by laser ablation-inductively coupled plasma mass spectrometry (LA-ICPMS) at the SUNY College of Environmental Science and Forestry. A USGS carbonate standard (MACS-3) was used to calibrate and correct for instrument drift. Spot size was 35 microns, and transects were run from core to outer edge at 5 microns/second.
