The serial remote sensing based imageries clearly revealed large scale of upwelling within regional enhancement chlorophyll‐ a (Chl‐ ) concentration in the southern East China Sea (ECS) after passage super typhoon Hai‐Tang July 2005. After on 22 July, area (<26°C) expanded rapidly to 9146 km 2 shelf‐break. increased persisted for more than week. Ocean color images also reveled that high Chl‐ >3.0 mg/m 3 appeared shelf region, where pattern matched terms location and time. On other...
We present wintertime variations and distributions of sea surface temperature (SST) fronts in the Taiwan Strait by applying an entropy‐based edge detection method to 10‐year (1996–2005) satellite SST images with grid size 0.01°. From climatological monthly mean maps gradient magnitude winter, we identify four significant Strait. The Mainland China Coastal Front is a long frontal band along 50‐m isobath near Chinese coast. sharp Peng‐Chang appears Peng‐Hu Channel extends northward around...
Abstract The Yellowfin Tuna Thunnus albacares is one of the major fish species caught around subsurface aggregation devices (FADs) in waters southwest Taiwan. However, how it interacts with other organisms FADs poorly known. In this study, diet and feeding habits juvenile were estimated from analysis stomach contents 1,477 specimens FLs ranging 24 to 108 cm stable isotope (202 specimens) collected indicated that FL < 50 mainly feed on larval purpleback flying squid Sthenoteuthis...
Abstract The environmental processes associated with variability in the catch rates of bigeye tuna Atlantic Ocean are largely unexplored. This study used generalized additive models (GAMs) fitted to Taiwanese longline fishery data from 1990 2009 and investigated association between variables identify influencing distribution Ocean. present findings reveal that year (temporal factor), latitude longitude (spatial factors), major regular target species albacore catches significant for...
Abstract A commercially significant small coastal forage fish, moonfish ( Mene maculata ), accounts for almost 98% of Taiwanese purse seine capture, primarily in the southwestern Taiwan region. Research indicates that climate indices affect fish catch and dispersal, while link between climatic variability this region is still unclear. This study found delayed period Pacific Decadal Oscillation (PDO), North (NPO) Gyre (NPGO) distribution rates off Taiwan. Understudied are environmental...
ABSTRACT Climate change poses a significant threat to marine ecosystems, potentially altering the distribution of organisms and causing many species migrate towards poles. The habitat changes targeted for fishing are likely affect activities livelihoods coastal communities. Hence, present study analyzed Indo‐Pacific king mackerel (IKM) in Taiwan Strait (TS) by using ensemble modeling considering two representative concentration pathway (RCP) scenarios (2.6 8.5) assess implications predicted...
Albacore tuna (Thunnus alalunga) is one of the important commercial species longline fishery in southern Indian Ocean (SIO). The satellite-based oceanographic data net primary production (NPP), sea-surface temperature (SST), sea surface salinity (SSS), mixed layer depth (MLD), height (SSH) and eddy kinetic energy (EKE), were used to evaluate effects conditions on hotspot habitat for explore spatial variability these features SIO using generalized additive model (GAM) maximum entropy models...
Albacore tuna (Thunnus alalunga) is one of the important commercial species longline fishery in South Indian Ocean (SIO). The satellite-based oceanographic data sea-surface temperature (SST), sea surface chlorolyll-a (SSC), salinity (SSS), mixed layer depth (MLD), height (SSH) and eddy kinetic energy (EKE), were used to evaluate effects conditions on potential fishing zones explore spatial variability these features SIO using maximum entropy models (MaxEnt). results revealed its for...
