Assessing The Vulnerability Of Fishery Villages Influenced By Climate Change And Anthropogenic Activity In The Coastal Zone Of The Tamsui River, Sheng-Yuan Teng, Ming-An Lee, Jhen Hsu, Tzu-Ping Lin, Yu-Chen Lin, Yi Chang
Journal of Marine Science and Technology
Coastal zones located in populated and rapidly developing areas face high risks of natural and anthropogenic disasters. In this study, a framework was developed to determine the indicators of vulnerability to natural and anthropogenic disasters in Chuwei and Tamsui, two northern Taiwanese fishing villages in the coastal zone of the Tamsui River. The analytical hierarchy process (AHP) was used to determine the vulnerability indices of the locations, with experts evaluating the weights assigned to a range of criteria, namely hydrological data (such as sea surface temperature and sea level), stakeholder perceptions, and fishery data. These two villages have a considerably …
Predicting The Catch Potential Of Skipjack Tuna In The Western And Central Pacific Ocean Under Different Climate Change Scenarios, Kuo-Wei Yen, Nan-Jay Su, Tooreka Teemari, Min-An Lee, Hsueh-Jung Lu
Predicting The Catch Potential Of Skipjack Tuna In The Western And Central Pacific Ocean Under Different Climate Change Scenarios, Kuo-Wei Yen, Nan-Jay Su, Tooreka Teemari, Min-An Lee, Hsueh-Jung Lu
Journal of Marine Science and Technology
Skipjack tuna (Katsuwonus pelamis) constitute an important migratory species that contributes significantly to the economy and the global fishery industry. Skipjack tuna play a vital role in the marine ecosystem, particularly in tropical waters of the western and central Pacific Ocean (WCPO). However, climate change may affect the characteristics of fishery resources, leading to substantial reallocation and reduction of the biomass of this species in the WCPO. In this study, catch and effort data for skipjack tuna were collected from a purse seine fishery and subsequently analyzed in combination with remote-sensing environmental variables and simulation data from climate models under …
Impact Of Climate Change On Shihmen Reservoir Water Supply, Tai-Yi Chu, Jyun-Long Lee, Wen-Cheng Huang
Impact Of Climate Change On Shihmen Reservoir Water Supply, Tai-Yi Chu, Jyun-Long Lee, Wen-Cheng Huang
Journal of Marine Science and Technology
This study evaluated the impact of climate change on the water supply of the Shihmen reservoir in northern Taiwan. Five downscaled general circulation models that represent the daily meteorological data of 2046-2065 were adopted. The future inflow of the Shihmen reservoir was estimated using the tank model. Subsequently, the water supply risk under the given demand and operating conditions was simulated and assessed. Compared with 2004-2011, the average annual precipitation of the Shihmen watershed in 2046-2065 is lower, particularly during the wet season (May-October). Therefore, the risk to the water supply will increase in the first cropping season (from March …
Seasonal Abundance Of Epiphytic Dinoflagellates Around Coastal Waters Of Jeju Island, Korea, Md. Mahfuzur Rahman Shah, So-Jeong An, Joon-Baek Lee
Seasonal Abundance Of Epiphytic Dinoflagellates Around Coastal Waters Of Jeju Island, Korea, Md. Mahfuzur Rahman Shah, So-Jeong An, Joon-Baek Lee
Journal of Marine Science and Technology
The seasonal abundance of epiphytic dinoflagellates in the intertidal zone of Jeju Island, Korea was quantitatively estimated by monthly collection of macroalgal samples (Rhodophyta, Phaeophyta, and Chlorophyta) from six sampling locations from July 2012 to June 2013. Ten epiphytic dinoflagellate taxa, including eight potentially toxic species Amphidinium carterae, A. operculatum, Gambierdiscus sp., Ostreopsis ovata, Prorocentrum concavum, P. emarginatum, P. lima, and P. rhathymum, were identified. Two Amphidinium and three Prorocentrum species are newly recorded in Korean coastal waters. A significant change in seasonal abundance was recorded with maximum (751.82 ± 223.12 cells g-1 wet weight of algae; cells g-1 hereafter) …
Fishing Vs. Climate Change: An Example Of Filefish (Thamnaconus Modestus) In The Northern East China Sea, Sukgeun Jung, Hyung Kee Cha
Fishing Vs. Climate Change: An Example Of Filefish (Thamnaconus Modestus) In The Northern East China Sea, Sukgeun Jung, Hyung Kee Cha
Journal of Marine Science and Technology
The main cause of annual fluctuations in catch and species composition of fisheries is usually uncertain, but a prevailing view has been that fishing effects are more critical than environmental variability. Filefish is a good anecdote: many Korean fisheries scientists have attributed the sudden collapse of Korean filefish fisheries in the early 1990s to overfishing, especially by trawl fisheries in the northern East China Sea (NECS). However, interdisciplinary researches have revealed that climate-driven, multi-decadal variability in oceanic conditions impacts both fish and fisheries around the world. To test the two alternative hypotheses (i.e., fishing and climate) as the major cause …
