Changes in marine environments affect fishery resources at different spatial and temporal scales ecosystems. Predictions from species distribution models are available to parameterize the environmental characteristics that influence biology, range, habitats of interest. This study used generalized additive (GAMs) fitted two spatiotemporal data sources, namely 1° grid observer record longline 2006 2010, investigate relationship between catch rates yellowfin tuna oceanographic conditions by...
Abstract Tseng, C-T., Su, N-J., Sun, C-L., Punt, A. E., Yeh, S-Z., Liu, D-C., and W-C. 2013. Spatial temporal variability of the Pacific saury (Cololabis saira) distribution in northwestern Ocean. – ICES Journal Marine Science, 70: 991–999. Logbook data for Taiwanese fishery multi-sensor satellite images 2006–2010 were used to characterize habitat (NWP). An empirical cumulative function (ECDF) approach identified that high cpue (catch per unit effort) occurred when sea surface temperature...

Modelling the impacts of environmental variation on distribution blue marlin, Makaira nigricans, in Pacific Ocean. – ICES Journal Marine Science, 68: 1072–1080. Blue marlin are distributed throughout tropical temperate waters The preference this species for particular habitats may affect its vulnerability to being caught. relationships between spatial pattern abundance oceanographic conditions, which be influenced by...
Abstract Chang, Y.-J., Sun, C.-L., Chen, Y., Yeh, S.-Z., DiNardo, G., and Su, N.-J. 2013. Modelling the impacts of environmental variation on habitat suitability swordfish, Xiphias gladius, in equatorial Atlantic Ocean. – ICES Journal Marine Science, 70: 1000–1012. We developed a index (HSI) model to identify optimal habitats swordfish (Xiphias gladius) Environmental variables, including sea surface temperature (SST), mixed layer depth (MLD), chlorophyll-a concentrations, height anomaly, as...
Abstract Blue marlin is distributed throughout tropical and temperate waters in the Pacific Ocean. However, preference of this species for particular habitats may impact its vulnerability to being caught. The relationship between spatio‐temporal patterns blue abundance environmental factors examined using generalized additive models fitted catch effort data from longline fisheries. presence marlin, rate given presence, are modeled separately. Latitude, longitude, sea‐surface temperature...
Offshore wind power is a valuable renewable energy source. However, the development of offshore farms facing many challenges, including understanding their impacts on ecosystems and society, as well knowledge gaps in research. In this study, bibliometric analysis was performed with aim providing comprehensive current global progress farm Three stages were considered for comparison research characteristics outcomes. Based total number scientific publications international collaboration ratio...
Taiwan Bank (TB) is located in the southern Strait (TS), where uplifted continental slope and bottom currents result formation of upwelling areas, which serve as crucial fishing grounds. Climate-induced fluctuations fish populations occur TS. However, how predation competition affect interspecies relationships TB ecosystem warrants clarification. In this study, we collected high-grid resolution data on fishery activity (2013–2019) constructed models by using Ecopath with Ecosim (EwE). Three...
Black sea bream, Acanthopagrus schlegelii, is among the most commercially valuable species in coastal fishery industry and marine ecosystems. Catch data comprising capture locations for gillnet fisheries, remotely sensed environmental (i.e., surface temperature, chlorophyll-a concentration, current velocity), topography (bathymetry) from 2015 to 2018 were used construct a spatial habitat distribution of black bream. This concentrated waters (<3 nm) December April (spawning season). The...
Swordfish, Xiphias gladius (Linnaeus, 1758), is a commercially important species that widely distributed throughout three oceans. This inhabits oceanic waters with preferred environmental ranges and migrates vertically to the surface layer for feeding. However, spatial distribution pattern habitat preferences of swordfish have been rarely studied in Pacific Ocean due wide geographic range this species. study examined variables using two approaches, generalized additive models suitability...
Blue marlin are sexually dimorphic in size-at-age and other biological characteristics. However, few studies have examined the possible impact of sexual dimorphism on population parameters ratios fishing to total mortality (the exploitation ratios) for this species. We analyzed sex-specific catch-at-length data blue collected from Taiwanese tuna longline fishery northwest Pacific Ocean, ranging between 100–311 cm eye fork length (EFL) females 100–236 EFL males, show that proportion catch sex...

Blue marlin, widely distributed throughout the Pacific Ocean, are sexually dimorphic, have certain preferred habitats, and migrate seasonally. These characteristics been ignored in previous stock assessment models. A population dynamics model that includes spatial structure, sex age structure was therefore constructed fitted to fisheries data for blue along with information on relative density of over space derived from a habitat preference uses oceanographic biological variables sea-surface...
Length and mass data for 1260 (536 females, 683 males, 41 sex unknown) striped marlin Kajikia audax were collected at the fish markets of Tungkang, Singkang Nanfangao from July 2004 to September 2010. Of these samples, 534 gonads (236 females 298 males) ranging 95 206 cm in eye‐to‐fork length ( L EF ) 8 88 kg round M R ), collected. Chi‐square tests indicated ratios homogeneous among months 2006–2008, but not 2005, 2009 2010; there significant differences ratio by size. The overall S...
To gain a better understanding of the trophic ecology Pacific blue marlin Makaira nigricans off eastern Taiwan, nitrogen and carbon stable isotopes (δ 15 N δ 13 C) Bayesian mixing models were used to explore dynamics potential ontogenetic feeding shifts across M. different size classes. samples from east Taiwan ( n = 213) Palau 37), as well their prey 70), collected during 2012 2013.

Mixed fisheries refer to fishing activities that catch more than one species simultaneously, and a may be fished using different gear. A trawl fishery shares these features exploit multiple with diverse gear strategies. The situation becomes complex when interactions among fleet dynamics, activities, resources are involved influence each other. Information regarding the operational patterns hidden in set of long-term big data. This study aims investigate structure dynamics Taiwan for spatial...
Abstract Su, N.-J., Sun, C.-L., Punt, A. E., Yeh, S.-Z., DiNardo, G., and Chang, Y.-J. 2013. An ensemble analysis to predict future habitats of striped marlin (Kajikia audax) in the North Pacific Ocean. – ICES Journal Marine Science, 70: 1013–1022. Striped is a highly migratory species distributed throughout Ocean, which shows considerable variation spatial distribution as consequence habitat preference. This may therefore shift its range response changes marine environment driven by climate...
