The blue shark ( Prionace glauca ) is the most frequently captured shark in pelagic oceanic fisheries, especially pelagic longlines targeting swordfish and/or tunas. As part of cooperative scientific efforts for fisheries and biological data collection, information from fishery observers, scientific projects and surveys, and from recreational fisheries from several nations in the Atlantic and Indian Oceans was compiled. Data s...

The feeding ecology of two dominant lanternfishes Diaphus garmani and Diaphus chrysorhynchus was studied in the continental slope region of the East China Sea, off western Kyushu (31–33° N; 128–130° E). Stomach contents of D. garmani were composed mainly of crustacean zooplankton, such as copepods, euphausiids, decapod larvae and amphipods, and also of appendicularians. Stomach contents of D. chrysorhynchus were composed mainl...

Growth and reproductive characteristics of gold striped amberjack Seriola lalandi collected in the waters off western Kyushu from April 2003 to March 2008 were determined based on vertebral centrum readings and gonad histology, respectively. Translucent and opaque zones on vertebral centrum were identified, and the number of opaque rings counted. Von Bertalanffy growth parameters did not significantly differ between males and...

Feeding habits and gill raker morphology were examined for the three major planktivorous pelagic fishes, Japanese anchovy Engraulis japonicus , Pacific round herring Etrumeus teres and Japanese jack mackerel Trachurus japonicus , off the northern and western coasts of Kyushu, in the north‐eastern part of the East China Sea in the summer months of 2001. Using fishes in the same size range (80–140 mm, standard length), the stoma...
