Significant measures at improving aquaculture health have to be taken since disease outbreaks commonly occur in the fast-growing industry. This study aimed determine immunomodulatory properties of an indigenous Malaysian microalgae species, Isochrysis galbana (IG), on red hybrid tilapia (Oreochromis spp.). Then, potential biomarkers for were identified through metabolic changes spleen using pro...

After an exceptional hydroclimatic year, a “massive green algae bloom”, dominated by the autotrophic picoeukaryote Picochlorum sp, was observed in 2018–2019 Thau lagoon. Oyster farmers informed decision-makers and scientists about alarming halt to growth, loss of flesh weight abnormal mortality commercial size oysters, whereas mussel no adverse effects. Two hypotheses were tested. First, Medite...

We describe the results of a laboratory scattering experiment performed to investigate differences in the optical scattering properties between five common phytoplankton species (Dunaliella tertiolecta, Isochrysis galbana, Nanochloropsis, Skeletonema costatum, and Thalassiosira weissflogii). Data sets were taken at scattering angles 1u to 170u at incident polarizations parallel and perpendicula...

To reveal the biosynthetic pathway of long-chain polyunsaturated fatty acids (LC-PUFA) in Ruditapes philippinarum , herein, two acid desaturases (Fads, including one Δ5 Fad and Δ6 Fad-like) three elongases very (Elovls, Elovl2/5 Elovl4-like) genes were firstly cloned from this bivalve their tissue distributions examined. Results showed that newly Fads Elovls contained corresponding conserved fu...

Numerous recent studies have identified microalgae biofuel as one of the major renewable energy sources for sustainable development due to their high biomass productivity, lipid content, and availability locally adapted strains in various geographical locations. There been minimal on fatty acid composition production local species Sabah, Malaysia. Thus, screening capable producing biodiesel can...

The need to replace petroleum fuels with alternatives from renewable and more environmentally sustainable sources is of growing importance. Biomass-derived biofuels have gained considerable attention in this regard, however first generation biofuels from edible crops like corn ethanol or soybean biodiesel have generally fallen out of favor. There is thus great interest in the development of met...

Effects of salinity, temperature and food concentration on early development of the polychaete Hydroides elegans (Haswell) were examined in 4 laboratory experiments. Three 2-factor experlments tested the effects of salinity (15 to 35sl,,] and temperature (15 to 30°C ) on the survival and duration of development of H elegans from newly-released oocyte to 2-cell, 2-cell to blastula, and blastula ...
