“…Analytical techniques used to decipher ontogenetic changes via otolith chemical time-series typically entail spot, line, or plane analyses of scans made with an electron probe micro-analyzer (EPMA) (H.

Otolith microchemistry provides valuable information about the environmental history of individual fish, but few studies have considered the influence of population or stock on life history traits. This study used the Sr/Ca ratio as an index of habitat use of spinyhead croaker Collichthys lucidus from 2 different populations (northern and southern China populations), including lifetime otolith microchemistry profiles (n = 63 fish) and determinations of natal habitat selection (n = 352 fish). The otolith data revealed 3 life history patterns in C. lucidus: Pattern 1 individuals spent most of their lifetime (>95%) in mesohaline waters (Sr/Ca range: 3-7 mmol mol-1), particularly during early growth; Pattern 2 individuals migrated from hyperhaline waters (Sr/Ca ≥ 7 mmol mol-1) to mesohaline waters; and Pattern 3 individuals migrated from oligohaline waters (Sr/Ca < 3 mmol mol-1) to mesohaline waters. Pattern 2 and Pattern 3 were specific to the northern and southern China populations, respectively, and Pattern 1 was shared by the 2 populations. The otolith core Sr/Ca ratios showed that most C. lucidus selected mesohaline waters as their natal habitat (i.e. 90.6% of 352 total individuals); 12.5% (19 of 152) selected hyperhaline waters and fell within the northern China population, and 7% (14 of 200) selected oligohaline waters and fell within the southern China population. These results indicate that life history diversity exists in this species, as the pattern of habitat use largely differed between the northern and southern China populations. The overall findings highlight that the behavior of different populations should be considered when determining fish migration histories.

The detailed population genetic structure of the rare endangered latid fish akame Lates japonicus with extremely low genetic diversity revealed from single-nucleotide polymorphisms

Accurate knowledge of spatial population structure is crucial for species conservation and management, but low genetic diversity of endangered species makes it di cult to ascertain this information. In the Japanese lates or akame, Lates japonicus, an endangered sh known to have extremely low genetic diversity among vertebrates, mtDNA and AFLP marker analyses failed to clearly partition individuals into the two main distribution areas (Kochi and Miyazaki prefectures), although a weak but signi cant genetic difference between these regions was detected. Here, we conducted individual-based clustering analysis and sibship reconstruction to evaluate the species' population genetic structure by using 282 yearlings collected from four sites in Kochi and Miyazaki prefectures. We used single nucleotide polymorphism (SNP) markers from double-digest restriction-site-associated DNA sequencing (ddRAD-seq). Although our data revealed extremely low genome-wide nucleotide diversity (π = 0.00006) in akame, the clustering analysis showed a clear genetic difference between the two regions, with a small number of migrants and individuals with admixed ancestry. Sibship analysis estimated that the only full-sib pairs of individuals were from the same prefecture and no pairs were from different prefectures. From these results, we conclude that the akame population of Kochi and Miyazaki prefectures are different management units, and for revealing detailed population genetic structure of endangered species which has low genetic diversity, it is effective to conduct individual-based analysis and sibship reconstruction by using juvenile samples and many SNPs from ddRAD-seq.
