    Major forage fishes spend their vulnerable early life stages in the Kuroshio and its neighboring waters where phytoplankton standing stocks are much lower than in coastal areas. Nevertheless, little is known of how mesozooplankton and fish larvae with their high biodiversity are supported in the Kuroshio ecosystem. Here we report stable isotope ratios of carbon (δ13C) and nitrogen (δ15N) for mesozooplankton and fish larvae from coastal to pelagic sites in the East China Sea to evaluate trophic sources and pathways at lower trophic levels in planktonic food webs under different environmental regimes. Although δ13C and δ15N in mesozooplankton and fish larvae varied among taxonomic groups and sites, mesozooplankton δ13C and δ15N tended to be lower for particle-feeders than carnivores and fish larvae and at more pelagic sites than in coastal waters. There were significant linear regressions between δ15N and δ13C of mesozooplankton communities, with the similar slopes among sites and lower intercepts at more pelagic sites. The δ15N and δ13C of small copepods, euphausiids, ostracods, appendicularians and fish larvae were aligned close to the regression line covering all regions, indicating that these were trophic sources and pathways to mesozooplankton and fish larvae. Our results suggest that trophic sources of mesozooplankton and fish larvae are supported through copepods and appendicularian-integrated microbial production and are more dependent on diazotrophic production in more pelagic waters.

    <p>Post-harvest freshness of trawl-caught deep-water mud shrimp <i>Solenocera melantho</i> was assessed by measuring the concentration of ATP-related compounds in the tail muscle. In the field study, trawls were towed touching the seabed to catch the shrimps for 15 min, and then the tows were continued off the seabed for 35 and 65 min to prevent more shrimps being caught and to simulate trawling with <i>S. melantho</i> in the codend at the towing speed of 2.0 knots. Underwater video camera was connected to record the behavior of the catches inside the codend during towing. <i>S. melantho</i> were stored on ice for 5 days after harvesting. <i>S. melantho</i> were observed to move toward to the codend, and continued to be stationary without moving after reaching the codend during the trawling. The concentrations of ATP-related compounds during the storage were not different significantly in the tow duration of 35 and 65 min. ATP were found when the catches were retrieved from the codend on the deck of the vessel. Decomposition speed of ATP is high, and AMP and IMP were accumulated during the storage. The onset of HxR was observed after 2-day storage, and Hx was not found during the storage of 5 days.</p>
