Antibiofilm Activities Of Extracts Of The Macroalga Halimeda Sp. From The Red Sea, Alaa Aref Abdullah Gadhi, Mohsen M. O El-Sherbiny, Abdul Mohsin A Al-Sofyani, Mohammad Abdulaziz Ba-Akdah, Sathianeson Satheesh
Journal of Marine Science and Technology
Marine macroalgae generally keep their surface free from fouling organisms by their antifouling defence. Antifouling activity has been attributed to the production of secondary metabolites. In the present study, antifouling performance of the macroalga Halimeda sp., collected from the Red Sea coastal waters, was assessed using extracts prepared through various methods, including surface extraction, wet sample extraction and dried sample extraction. The solvents methanol and hexane were used to assess the effect of solvents on bioactivity. Results indicated that extracts of the macroalga inhibited growth and settlement of a biofilm-forming bacterial strain. Though the extracts prepared using different methods and …

The Effects Of Different Dietary Protein Sources On The Growth Performances And Body Composition Of The Rock Porgy, Oplegnathus Fasciatus, I-Hao Huang, Jen-Hong Chu, Angela Chien, Shyn-Shin Sheen
Journal of Marine Science and Technology
This study investigated the effects of different dietary protein sources on the growth performance and muscle composition of the rock porgy, Oplegnathus fasciatus. Four isonitrogenous (48% crude protein) and isolipidic (10% crude lipid) diets were formulated with Peruvian fishmeal (PFM), Taiwanese fishmeal (TFM), poultry by-product meal (PBM) and meat and bone meal (MBM), respectively. The rock porgy (mean initial weight 10.58 g) were reared in 12 tanks and fed with one of the four treatment diets in triplicate for six weeks. The rock porgy fed with diet TFM had significantly higher weight gain than those fed with the other treatment …

Tank hygiene is an essential aspect for successful fingerling production but can involve substantial workload to maintain. The purpose of this research is to develop and test a new version of a flow-driven, self-rotating tank deposit remover to automatically and quickly remove the deposit for grouper nurseries. The deposit remover has a suction tube lying on the bottom of the tank. Water flowing through the suction tube drives a propeller to rotate the tube while sucking up the solids on the bottom. Previous versions of the deposit remover suffer from incomplete solid removal and a long operating time. An integrated …
Seasonal Variations In Trophic Links Between Microzooplankton And Nanoflagellates In A Coastal Ecosystem, An Yi Tsai
Seasonal Variations In Trophic Links Between Microzooplankton And Nanoflagellates In A Coastal Ecosystem, An Yi Tsai
Journal of Marine Science and Technology
Using incubation experiments with size-fractionated coastal waters, this study calculated the growth and loss rates of nanoflagellates in a coastal ecosystem of the subtropical western Pacific along a rocky shore in northeastern Taiwan. Samples were taken monthly from September 2014 to August 2015. Seasonal variations in growth rates of heterotrophic nanoflagellates (HNF) and pigmented nanoflagellates (PNF) ranged from 0.17 to 1.13 d-1 and 0.05 to 1.21 d-1, respectively. This study found that grazing had a significant impact on nanoflagellate community (PNF: 0.14 to 0.39 d-1; HNF: 0.12 to 0.52 d-1), accounting for about 15-30% for PNF and 18-60% for HNF …

We aimed to investigate biofouling characteristics on the surfaces of adsorbents and reservoirs used for lithium recovery from seawater. Three types of adsorbents (type 1, 2 m sphere-shaped; type 2, 2 mm circular; and type 3, 2 mm rod-shaped) and a reservoir (polyurethane sponge) were immersed in seawater for 30 days. Biofouling on the surface of adsorbents and the reservoir was initiated by Vibrio, Alteromonas, and Pseudoalteromonas, suggesting that primary colonization of Gammaproteobacteria was an important feature of the biofouling on the surface. We observed pore size-dependent bacterial composition on the adsorbents; only Alteromonas was found on type 1 adsorbent, …

Winter Abundance And Species Composition Of Anchovy Larvae Associated With Hydrological Conditions In The Coastal Waters Of Tanshui, Taiwan, Yi-Chen Wang, Wen-Yu Chen, Yu-Kai Chen, Yi-Chun Kuo, Ming-An Lee
Journal of Marine Science and Technology
The present study investigated changes in the winter abundance and composition of anchovy larvae associated with hydrological conditions in the coastal waters of Tanshui, Taiwan. A survey during the period of 2008-2014 revealed that the abundance of larvae caught using fyke nets varied from 123.9 to 28,314 ind/1000 m3 , whereas the surface water temperature and salinity ranged from approximately 17C to 18C and 32.84 psu to 33.72 psu, respectively. Engraulis japonicus (Japanese anchovy), Encrasicholina punctifer (buccaneer anchovy), and E. heteroloba (shorthead anchovy) were the dominant species of anchovy larvae, accounting for 0.17%-93.56%. In the La Niña years 2008 and …

Effect Of Different Algal Lees On Physicochemical Qualities Of Baked Potato Chips, Wen-Chieh Sung, Chang Jer Wu, Chorng Liang Pan, Yu Chin Lin
Journal of Marine Science and Technology
Lees of three different algae (a green alga Ulva fasciata, a brown alga Sargassum cristaefolium and a red alga Kappaphycus contonii), representing the leftovers from a seaweed polysaccharide extraction process using hot water and enzymes, were added separately to potato chip dough at a level of 2.5%. Antioxidant activity, water activity, color, firmness, overall acceptability and proximate composition of baked potato chips prepared from these dough and from dough without algal lees were evaluated. The rehydration capacity (49.87%) of red algal lees was significantly higher than that of the other lees. The firmness of baked potato chips with red algal …

Journal of Marine Science and Technology
This paper describes the application of a coupled surge-wave model for simulating storm surge and wave along Taiwan coast. The simulations were conducted with an integrated surge-wave modeling system using a large coastal model domain wrapped around the island of Taiwan, with a grid resolution of 50-400 m. Simulations were made with tide only, with wind and tide, and with tide and wind and wave. The first part of the paper describes the hindcasting of historical typhoons. Hindcasting of Soudelor in 2015 revealed the significant effect of waves on storm surge when wave exceeded 11 m. Both the water level …

Many marine organisms have developed the capability of producing unique metabolites and thus are highly likely to contain anti-infective agents. This study was conducted to investigate extracts of three seaweeds (Caulerpa racemosa, Caulerpa sertularioides, Kappaphycus alvarezii), two soft corals (Lobophytum microlobulatum, Sarcophyton auritum) and a marine sponge (Spheciospongia vagabunda) collected from Malaysian coast for antibacterial, antifungal, antiviral and cytotoxic activities. The samples were subjected to sequential solvent extraction in order to obtain hexane, chloroform, ethyl acetate, ethanol, methanol and water extracts. The antibacterial and antifungal activities were studied using a colorimetric broth microdilution method. The hexane extract of L. microlobulatum …

Chlorophyll Concentration Derived From Microwave Remote Sensing Measurements Using Artificial Neural Network Algorithm, Young-Heon Jo, Dae-Won Kim, Hyuna Kim
Journal of Marine Science and Technology
Ocean color optic remote sensing has been used to estimate various biogeochemical constituents to monitor ocean environmental changes in coastal regions and global open oceans. However, the most problematic issue in utilizing ocean color measurements is cloud coverage. Thus, this study introduces a neural network (NN) algorithm to derive Chlorophyll a (Chl) concentrations, which are unavailable due to the presence of clouds. Because ocean color remote sensing depends on cloud coverage, microwave measurements, including sea-surface temperature, cloud, water vapor, precipitation, and winds, were used as inputs for the NN algorithm. Accordingly, the NN algorithm was designed to predict Chl using …

Journal of Marine Science and Technology
The proximate composition, pH, free amino acids, ammonia and nucleotide-related compounds of raw abalone, commercial processed abalone and abalone analogues were investigated. Taurine was the dominant free amino acid (FAA), accounting for 61.4% of the total FAA in raw hybrid abalone and 29.9% in processed abalone. Abalone analogue products had a high amount of free amino acids, but only 0.3-2.5% taurine. The proximate composition and pH value of abalone changed only slightly after blanching and processing, while the taurine and glycogen content decreased by 50%. FAA profiles were significantly different between commercial processed abalone and analogue products, both of which …
