Publikováno v: ICES Journal of Marine Science. 77:581-592

Biomass of the yellowtail Seriola quinqueradiata, an important fishery resource in Japan, has increased about threefold over the past 20 years to ∼300 thousand metric tons. We examined the interannual variations in distribution and abundance of S.

Publikováno v: Ichthyological Research. 64:45-53

The new generic name Nemoossis is proposed for the albulid species Pterothrissus belloci Cadenat 1937, a species endemic to the eastern Atlantic Ocean. Nemoossis differs from other genera in the family Albulidae as follows: longer dorsal-fin base, ab

Interannual variations in rates of larval growth and development of jack mackerel (Trachurus japonicus) in the East China Sea: implications for juvenile survival

Autor: Chiyuki Sassa, Youichi Tsukamoto, Motomitsu Takahashi, Kou Nishiuchi

Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 73:155-162

Interannual variability in somatic growth rate during the larval stage and age at the onset of metamorphosis as a proxy for the development rate of jack mackerel (Trachurus japonicus) were examined in relation to habitat conditions during 2005 to 201

Publikováno v: Fisheries Science. 81:663-671

The biological characteristics of Conger myriaster in the East China Sea were studied in May and June (summer), and in November and December (winter), from 2009 to 2010. C. m yriaster was collected mainly at stations in the survey area contained with

Distribution, hatch-date, growth, and mortality of larval Benthosema pterotum (Pisces: Myctophidae) in the shelf region of the East China Sea

Autor: Chiyuki Sassa, Youichi Tsukamoto, Motomitsu Takahashi

Publikováno v: Journal of the Marine Biological Association of the United Kingdom. 95:161-174

We examined the distribution, hatch-date, growth, and mortality of larval Benthosema pterotum, a dominant pseudoceanic myctophid in the shelf region of the East China Sea, during early autumn when the main spawning has been predicted. This species is

Publikováno v: Journal of Plankton Research. 36:542-556

Distribution, growth and mortality of jack mackerel Trachurus japonicus larvae ,10 mm standard length (SL) were investigated in relation to habitat conditions in the southern East China Sea (ECS) in 2005, 2007 and 2009. In all the years, the center o

Reproductive biology of Benthosema pterotum (Teleostei: Myctophidae) in the shelf region of the East China Sea

Autor: Chiyuki Sassa, Seiji Ohshimo, Hiroshige Tanaka, Youichi Tsukamoto

Publikováno v: Journal of the Marine Biological Association of the United Kingdom. 94:423-433

Benthosema pterotum is a dominant myctophid in the shelf region of the East China Sea (ECS). They are a key species linking secondary producers and upper trophic levels. We examined the reproductive biology of B. pterotum in the ECS, based on 3065 sp
