Influence Of The Marine Environment Variability On The Yellowfin Tuna (Thunnus Albacares) Catch Rate By The Taiwanese Longline Fishery In The Arabian Sea, With Special Reference To The High Catch In 2004, Kuo-Wei Lan, Tom Nishida, Ming-An Lee, Hsueh-Jung Lu, Hsiang-Wen Huang, Shui-Kai Chang, Yang-Chi Lan Oct 2012

Influence Of The Marine Environment Variability On The Yellowfin Tuna (Thunnus Albacares) Catch Rate By The Taiwanese Longline Fishery In The Arabian Sea, With Special Reference To The High Catch In 2004, Kuo-Wei Lan, Tom Nishida, Ming-An Lee, Hsueh-Jung Lu, Hsiang-Wen Huang, Shui-Kai Chang, Yang-Chi Lan

Journal of Marine Science and Technology

In this study, we collected Taiwanese longline (LL) fishery data and environment variables during the period of 1998- 2004 to investigate the relationship between LL catch data of yellowfin tuna (YFT) and oceanic environmental factors using a principal component analysis (PCA). Results of the PCA showed that monthly variations in catch per unit effort (CPUE) values were significantly correlated with the sea surface temperature (SST), subsurface temperature at 105 m, thermocline depth (horizontal) gradient magnitude, chlorophyll-a concentration, and fish size. April and May were the warmest months of the year in terms of the SST, and the thermocline was generally …


Use Of Real-Time Pcr To Detect Surimi Adulteration In Vegetarian Foods, Ching-Yang Cheng, Yeu-Ching Shi, Sin-Rong Lin, Chi-Chiang Chou, Chin-Cheng Huang Oct 2012

Use Of Real-Time Pcr To Detect Surimi Adulteration In Vegetarian Foods, Ching-Yang Cheng, Yeu-Ching Shi, Sin-Rong Lin, Chi-Chiang Chou, Chin-Cheng Huang

Journal of Marine Science and Technology

Vegetarian foods are abundant in the domestic market. It is found that animal ingredients have been added into vegetarian products to improve the texture and taste. Surimi adulteration in vegetarian food is an area of concern for vegetarians. The α-skeletal actin gene of aquatic animals as novel specific primers and probe of Actinopterygii in 36 fish species are tested using real-time PCR method. It was found that all of the 36 fish species of Actinopterygii showed positive results. The 10 surimi products, 10 surimi-based products containing fish components showed positive results. All of the 10 fresh foods containing no fish …


Effect Of Mulberry Lees Addition On The Quality Of Bread And Anthocyanin Content, Jean-Yu Hwang, Wen-Chieh Sung Oct 2012

Effect Of Mulberry Lees Addition On The Quality Of Bread And Anthocyanin Content, Jean-Yu Hwang, Wen-Chieh Sung

Journal of Marine Science and Technology

Mulberry lees were added to bread dough at levels of 10%, 20%, and 30%. Loaves were prepared using the straight dough procedure. Bread volume, crust and crumb color, crumb texture, flavor and overall acceptability were evaluated. Anthocyanin content of crumbs was determined for 5 days storage duration. The volume of bread was decreased (p < 0.05) as the mulberry lees addition amount increased. Overall acceptability of 10% mulberry lees addition bread was highest among all breads. There was no significant difference in crumb texture except the firmness of 30% mulberry lees addition was higher than other groups. Addition of mulberry lees increased the anthocyanin content of crumb. Oxidation of anthocyanin occurs in crumbs during storage. Mulberry lees could be added to bread within 20% level for enhancing the nutritional quality and characteristics of bread.


Fragmentation And Characteristics Of Recombinant Endochitinase Expressed In Escherichia Coli, Wei-Ming Chen, Gen-Hung Chen, Shann-Tzong Jiang Aug 2012

Fragmentation And Characteristics Of Recombinant Endochitinase Expressed In Escherichia Coli, Wei-Ming Chen, Gen-Hung Chen, Shann-Tzong Jiang

Journal of Marine Science and Technology

A recombinant endochitinase fused with hexahistidine (rEC-H) was expressed and characterized. After Ni affinity chromatography, the recovery, purification-fold and specific activity of rEC-H were 88.8%, 13.4 and 142.1 U/mg, respectively. The purified rEC-H had optimal pH and temperature at pH 7.5 and 60°C, respectively and was stable at pH 4.0-9.0 and


Double-Power Double-Heterostructure Light-Emitting Diodes In Microalgae, Spirulina Platensis And Nannochloropsis Oculata, Cultures, Yean-Chang Chen, Meng-Chou Lee Apr 2012

Double-Power Double-Heterostructure Light-Emitting Diodes In Microalgae, Spirulina Platensis And Nannochloropsis Oculata, Cultures, Yean-Chang Chen, Meng-Chou Lee

Journal of Marine Science and Technology

The growth conditions of two microalgae, Spirulina platensis and Nannochloropsis oculata, were tested under various light sources including white cold DDH GaAlAs LED, traditional fluorescent lamps and natural light cultures, with no difference found in the growth of biomass, indicating that white cold DDH GaAlAs LED could replace traditional fluorescent lamps, thus providing for large saving on electricity costs and preservation of cultural space. To date, the use of white cold DDH GaAlAs LEDs as light source for microalgal cultures seems to be largely unstudied.


Thermal Impacts Of A Coal Power Plant On The Plankton In An Open Coastal Water Environment, Keun-Hyung Choi, Young-Ok Kim, Joon-Baek Lee, Soon-Young Wang, Man-Woo Lee, Pyung-Gang Lee, Dong-Sik Ahn, Jae-Sang Hong, Ho-Young Soh Apr 2012

Thermal Impacts Of A Coal Power Plant On The Plankton In An Open Coastal Water Environment, Keun-Hyung Choi, Young-Ok Kim, Joon-Baek Lee, Soon-Young Wang, Man-Woo Lee, Pyung-Gang Lee, Dong-Sik Ahn, Jae-Sang Hong, Ho-Young Soh

Journal of Marine Science and Technology

Over a five-year period, this study examined the overall impact of coal power plant cooling processes on entrained copepods and the local plankton community on the west coast of Korea. Mortality differences between the intake and discharge water of the single most dominant copepod, Acartia hongi, were positively correlated with temperature differences between the two locations. Laboratory tests showed copepod sensitivity to temperature increase, and with very low chlorine concentration applied, thermal stress was the major source of copepod mortality. Chlorophyll a concentration, ciliate abundance, and total copepod abundance at the intake showed no discernable differences from the values at …


Additions To The Taiwan Marine Eel Fauna With First Records Of Three Rare Moray Eels (Anguilliformes: Muraenidae), Kar-Hoe Loh, Kwang-Tsao Shao, Hong-Ming Chen Apr 2012

Additions To The Taiwan Marine Eel Fauna With First Records Of Three Rare Moray Eels (Anguilliformes: Muraenidae), Kar-Hoe Loh, Kwang-Tsao Shao, Hong-Ming Chen

Journal of Marine Science and Technology

The specimens of three new records of moray eels (Anguilliformes: Muraenidae) were identified for the first time off the eastern (Changbin) and southern (Kenting) coast of Taiwan. They were Enchelynassa canina (Quoy and Gaimard), Gymnothorax elegans Bliss and Gymnothorax fuscomaculatus (Schultz). The monotypic genus Enchelynassa which had only one species in the genus was also a newly recorded genus to Taiwan. In this paper, we reported the three rare moray species, included diagnostic characters and the fresh coloration on whole body, head, dorsal and ventral sides; as well as their dentitions; and the key to the relative species.
