Data for CKMR abundance estimation for thornback ray (Raja clavata) in the central Bay of Biscay

input data, tmb (c++) and r code for close-kin mark recapture (ckmr) abundance estimation for two subpopulations of thornback ray (raja clavata) in the central bay of biscay (offshore and gironde estuary, see figure). samples were taken between 2015 to 2020. parent-offspring pairs were identified using snp genotype information. birth years of individuals were estimated using length information and growth curves by sex.

输入数据、TMB（C++）和R代码，用于估算中央比斯开湾（包括离岸和吉龙德河口，见图）中两种刺鳐（Raja clavata）亚种近缘标记重捕（CKMR）的丰度。采样时间介于2015年至2020年之间。通过SNP基因型信息识别亲子对，利用长度信息和按性别划分的生长曲线估算个体的出生年份。
