An acoustic and trawl pilot survey using a small vessel was conducted in Jinhae bay of the South Sea of South Korea on April 13~14, May 11~13 and June 8~10, 2015. During the survey, acoustic data was collected and bottom trawls were conducted at the same time. First, various noises were eliminated by using the Park method based on the Wang method (Wang et al., 2015;Park et al., 2015), the species compositions and catch rate from each bottom trawl were observed, and spatial distribution of fishery resources in the water column and their nautical area scattering coefficient (NASC) were investigated through acoustic data. During the entire survey period, 12 orders, 33 families and 41 species were caught.The most caught species in April, May and June were Okamejei kenojei, Zoarces gilli and Pholis nebulosa, respectively.

“…Most nutrient limitation assessments using bioassay experiments in estuaries with these characteristics have been conducted in laboratories rather than in field cultures that reflect real-world conditions [2,14,15,[19][20][21]. Furthermore, nutrient limitation assessments in the study site have only been conducted in the freshwater zone, and no assessments have been conducted in Mokpo Port, a saltwater zone.…”

The Yeongsan River estuary is experiencing increased concentrations of nutrient and organic matter due to its estuary bank (sea dike). The opening of floodgates at the estuary bank leads to a substantial inflow of freshwater into the saltwater zone, thereby resulting in water quality changes. Our study evaluated spatiotemporal variations in nutrient limitation in the freshwater and saltwater zones in the Yeongsan River estuary, which is expected to fluctuate with the changing seasons. We utilized the N:P ratio to evaluate the potential nutrient limitation and conducted bioassay experiments to directly assess actual nutrient limitation. The N:P ratio showed that P was the limiting nutrient in both the long-term (2004–2008) and during our field investigation. However, the bioassay experiment revealed that in the freshwater zone, P was limited in spring and winter (p < 0.05), while no nutrient was limited in summer and fall. In the saltwater zone, we observed P limitation in spring and winter (p < 0.05) and N limitation in fall (p < 0.05), whereas no nutrient limitation was observed in the summer. These results demonstrate that actual nutrient limitation, which directly influences phytoplankton growth, varies spatiotemporally in response to freshwater discharge in the Yeongsan River estuary.
