“…The ratio of Ba:Ca changes across salinity gradients and maybe the proxy of choice for identifying the movement of fish into low-salinity waters (Walther and Nims, 2015). In this study, the ratio of Ba:Ca was much higher in estuary-dependent C. lucidus than those in Scomberomorus niphonius, which spends most of its lifetime in marine (Liu et al, 2015;Pan et al, 2020). This could be partially explained as a consequence of rivers that flow to the coast, as the element Ba has higher concentrations in freshwater (Secor et al, 2001).…”

An integrated approach including analyses of different biological traits is a proven and powerful tool used to assess the population structures of fish species, which is vital for fishery stock conservation and management of wild resources. This study evaluates the use of three natural tags (i.e., microsatellites, parasites, and otolith nucleus chemistry) in order to describe the population structure of the spinyhead croaker, Collichthys lucidus, in the coastal waters of China, on evolutionary and ecological time scales. Spinyhead croaker was assigned with 86% accuracy to its regional origin (northern China vs. southern China) using all three natural tags. Accuracy decreased when incorporating only one type of natural tag (genetics: 19–69%; parasites: 30–60%; otolith chemistry: 51–86%) or when assigning the fish to a fine scale (sea areas: 44–64%; sampled estuaries: 19–66%). However, the overall accuracy assignment improved slightly compared with otolith chemistry (estuaries: 55 vs. 51%; sea areas: 66 vs. 64%; regions: 86 vs. 86%). Three natural tags and integrated results show that C. lucidus in Chinese coastal waters can be separated into distinct northern and southern Chinese stocks. Finally, this information should promote the development of effective conservation strategies and integrated fisheries management plans for this commercially important species.

“…Environmental conditions can affect the presence of fish and plankton in the waters. These parameters affect both metabolism, migration, food availability for fish [8][9]. Therefore, the purpose of this study was to map the horizontal and vertical distribution of plankton and small pelagic fish in Humbold Bay, Jayapura equipped with the distribution of environmental parameters.…”

Research on the distribution of fish and plankton in waters that are equipped with environmental parameters is needed to obtain maximum results and increase accuracy also it provides comprehensive information. The research, which was conducted in Humbold Bay, aimed to map the fish and plankton distribution data both vertically and horizontally and combine it with environmental parameters in the bay. Fish and plankton’s data was the volume backscattering strength (Sv) value obtained using the SIMRAD EK-15 device while environmental parameter data, such as temperature, salinity, and chlorophyll obtained from marine.copernicus.eu which processed in the 5-80 m depth range. The results showed that Humbold Bay had the highest average surface temperature distribution was 30 °C, with the highest average salinity from 35.89 ppt and the highest average chlorophyll value from 0.3859 mg/m3. The horizontal distribution of plankton had an average SV value of -76.63 dB, while the fish was -56.00 dB that evenly distributed. Vertically, the Sv of plankton decreased with increasing depth as well as the Sv of fish which its’ also did not have a distribution pattern in certain environmental parameters.

“…Several studies have indicated that mackerel in Japanese waters appears to have evolved a spawning strategy of short-term spawning timed to correspond to the seasonal peak abundance of their prey (Shoji et al, 1999;Shoji & Tanaka, 2001, and few studies have focused on the spawning strategy of mackerel in response to prey dynamics using in situ survey data in the China Sea, where the stock size is even larger (Pan et al, 2020).…”

“…Anchovy is the mackerel's dominant prey, particularly during the spawning migration of mackerel (Huh et al, 2006;Jin et al, 2010;Kishida, 1986), and larval anchovy is the important prey items for larval mackerel from the first feeding stage (Nakajima et al, 2013;Shoji et al, 1997Shoji et al, , 1999, which is why anchovy is commonly known as the "food of Japanese Spanish mackerel". Both mackerel and anchovy are among the most important fishery resources in the China Sea (Pan et al, 2020;Zhang et al, 2020;Zhao et al, 2003). Despite the overexploitation of many commercially important species in the China Sea under warming and intensive fishing, the catches of both mackerel and anchovy maintained a high yield (i.e., the fifth and second in China's marine fishery, respectively) in F I G U R E 1 Migration routes of (a) Japanese anchovy and (b) Japanese Spanish mackerel in the coastal China seas (these were redrawn from Zhang, 1965 andWei, 1980, respectively) recent years (Pang et al, 2018;Yu et al, 2020).…”

Japanese Spanish mackerel Scomberomorus niphonius and Japanese anchovy Engraulis japonicus are typical predator and prey species, respectively, with high commercial values in the China seas. However, the interspecific interaction, particularly the relationship between the two species during early life stages, is unclear. Here, based on ichthyoplankton surveys in the coastal Yellow Sea during 2013–2018, we analyzed the relationship between the two species based on egg occurrence and abundance in the context of species interaction. Spawning optimal temperature were examined for anchovy (13.0–18.0°C) and mackerel (15.0–20.0°C) based on egg occurrences and abundances in relation to sea surface temperature. We confirmed the peak spawning periods (May and June) and primary spawning areas (Haizhou Bay) for both mackerel and anchovy based on spatiotemporal distributions of two species eggs. Mackerel showed a high spawning overlap with anchovy, and anchovy egg abundance were also higher in overlap areas. Anchovy egg abundance may be more important for mackerel spawning than environmental variables, suggesting the significance of prey for predators during early recruitment. The temperature also has important effects on mackerel spawning and could be a threshold affecting mackerel spawning activity. Mackerel might have evolved a spawning strategy of short‐term spawning timed to coincide with the peak spawning of anchovy in the coastal Yellow Sea. These results highlight the effects of interspecific relationships on spawning strategy of anchovy and mackerel in the coastal Yellow Sea and may provide some insights for early recruitment studies of piscivorous fishes in the context of the match–mismatch hypothesis.
