Article Synopsis
- * Researchers found an average of 100,376 pieces of plastic per km and 446.16 grams of plastic per km on the sea surface, with significant accumulation in a specific area between the northern Kuroshio edge and Shikoku's coast.
- * The dominant type of plastic observed was small, white, fragmented particles (≤1 mm) made of polyethylene and polypropylene, with larger polystyrene plastics becoming more prevalent in the southern Kuroshio area due to fresh inputs from western Japan influenced by the northwest mon
Many laboratory experiments on aquatic vertebrates that inhabit closed water or coastal areas have highlighted negative effects of fast growth on swimming performance. Nonetheless, field studies on pelagic fishes have provided evidence of survival advantages of faster-growing individuals. To reconcile this contradiction, we examined the relationship between growth rate and swimming performance as a continuous function for juveniles of chub mackerel (Scomber japonicus) using 3D tracking analysis.

However, even when individual species are identified, the accurate estimation of their abundances by traditional eDNA analyses has been still difficult. We previously developed a novel analytical method called HaCeD-Seq (Haplotype Count from eDNA), which focuses on the mitochondrial D-loop sequence.
