Acoustic surveys were used to locate coastal Pacific herring (Clupea pallasii) spawning grounds, and the spatial and temporal patterns of their spawning in Jinhae Bay, Korea were examined. We deployed mooring with a newly designed autonomous echosounder for ~70 days during the Pacific herring spawning season in Jinhae Bay, from January to April 2018. At the same time, ship-based acoustic surveys were conducted to identify the spatial distribution twice, at 38 and 120 kHz, onboard the fishing vessel in January and April 2018 in the bay. Fish school signals, including those from adult Pacific herring, are often detected through ship-based acoustic surveys in January, from outside the bay. In the spring, weak scattering signals from fish larvae and zooplankton were continuously detected inside the bay. Backscatter at the mooring in the center of Jinhae Bay was low from mid-January to early March, gradually increasing to higher levels until the end of March. The backscatter observed from the mooring correlated well with ship-based acoustic surveys in the center of the bay. This study proposes that the mooring type acoustic echosounder is a valuable tool for temporal abundance information and other aspects of fish behavior.

Embryological development is followed over a period of ten weeks after hatching. The mode of formation of the components of the vertebral column is compared with that in Clupea harengus, and is described in detail where differences are observed or additional information is available. Development appears essentially similar in the two species, although in general more rapid relative to length in C. pallasii. At hatching, myotome formation is complete and the ultimate vertebral number of an individual is presumably determined by that time. During ossification of the vertebral column, complex growth gradients from one or more centres are observed.

The Pacific

The food of the Pacific herring Clupea pallasii consists during the larval stage principally of ova of various kinds with circular diatoms. No food was found in fish less than 9 mm. in length. Postlarvae and fry take the greatest variety of food, Copepoda and Cirripedia larvae being the most important items. Apparently the most readily available of suitable foods is taken. Adults confine themselves to a crustacean diet (except herring ova occasionally), Copepoda and Euphausiacea comprising the bulk of the food, Calanus predominating in the spring and Euphausia during the remainder of the year. Purse seined herring rarely contained any food. Copepoda are on the whole the most important food of the Pacific herring.

Timing Of Spawning

Acoustic surveys were used to locate coastal Atlantic cod (Gadus morhua) spawning grounds and examine spatial and temporal patterns of spawning in Placentia Bay, Newfoundland, Canada. The same three grounds were used in 1997 and 1998 (Bar Haven in the inner bay and Cape St. Mary's and Oderin Bank in the outer bay). Grounds had densities >0.1 fish·m-2 over scales of 100 m and >13% of mature females in spawning condition. Ground use and spawning timing differed between years. Mean spawning female densities were highest at Cape St. Mary's in 1997 (1.6 × 10-2 fish·m-2) and Oderin Bank in 1998 (1.0 × 10-2 fish·m-2). At all grounds, spawning peaked earlier in 1997 (April) than in 1998 (June-July). In both years, cod spawned at sub- or near-zero temperatures. "Spawning columns" were observed at sites and times having high densities of spawning females. Sex ratios suggested that males arrived first and stayed later, while females followed when ready to spawn, accompanied by juveniles. Older females spawned earlier and later than younger females. Peaks in density of spawning females and the proportion of females spawning did not coincide. Hence, the location and timing of spawning cannot be quantified solely from the proportions of females in spawning condition.
