Pacific bluefin tuna (PBF), Thunnus orientalis (Temminck and Schlegel, 1844), is highly migratory capable of traversing large distances throughout the North Ocean. The majority spawning activity has been reported only from Sea Japan western parts We have conducted larval surveys in these areas since 2009 (late period), used generalized additive models (GAM) with presence/absence data to analyze distribution respect oceanographic conditions, such as sea surface temperature chlorophyll-a...
Abstract We evaluated the behavior of skipjack ( Katsuwonus pelamis ), yellowfin Thunnus albacares ) and bigeye tuna T. obesus associated with drifting fish aggregating devices FAD s) in equatorial central Pacific Ocean. A total 30 [34.5–65.0 cm fork length FL )], 43 (31.6–93.5 32 (33.5–85.5 were tagged coded transmitters released near two s. At one s, we successfully monitored all three species simultaneously. Several individuals remained around same for 10 or more days. Occasional...

A central question in community ecology is how the number of trophic links relates to species richness. For simple dynamical food-web models, link density (the ratio species) bounded from above as increases; but empirical data suggest that it increases without bounds. We found a new upper bound on large marine communities with emphasis fish and squid, using novel methods avoid known sources bias traditional approaches. Bounds are expressed terms diet-partitioning function (DPF): average...
Yellowfin tuna Thunnus albacares is a commercially important fish species widely distributed between 40° S and N. Mixing rates tropical temperate areas of the western Pacific Ocean were investigated using stable carbon (δ 13 C otolith ) oxygen isotopes 18 O in whole otoliths small juveniles (mean: 5.8 cm standard length, SL) cores large (32.4 SL). The density distribution δ values for showed significant difference areas, whereas patterns almost identical areas. In addition, modal spanned...
[Longnose lancetfish (Alepisaurus ferox) were caught in a longline survey and from their stomach contents Phronima sedentaria observed to be associated with gelatinous organism that occurred at high frequency. A simple regression analysis was performed between the number of barrels P. sedentaria, highly positive correlation resulted (r2 = 0.978, p < 0.001, n 118). Although quantitative prevalence association zooplankton community study area can not discussed these limited seasonal data, it...
Sex-identification DNA markers are useful tools for sexing organisms that lack externally visible sexual dimorphism, and thus, they provide biological information ecological evolutionary studies. Tunas of the genus Thunnus (Scombridae), which comprises 8 species, dimorphism external morphology or coloration. In this study, we applied recently developed genotypic sex-identification Pacific bluefin tuna to other species evaluate their effectiveness in sex identification. A marker named ‘primer...
Abstract Age-reading protocols for tuna species using annual growth zones in thin-cut transverse otolith sections have produced greater age estimates than previous methods. Lifespan yellowfin (YFT) and bigeye (BET) (Thunnus albacares T. obesus) were validated up to 16–18 years the western North Atlantic Ocean bomb 14C dating current study extends approach YFT BET of central Pacific (WCPO). Archived otoliths from young-of-the-year (YOY) caught WCPO analysed establish a reference chronology...
