“…sublittoralis. These taxa were selected because they are widely distributed in intertidal sediments (Mitbavkar and Anil 2002, 2004, Du et al 2009) and have been found to be a major natural food source in some shellfish aquaculture industries (Qi-hua et al 1997, Onitsuka et al 2007, Parker et al 2007).…”

Temperature and irradiance are the most important factors affecting marine benthic microalgal photosynthetic rates in temperate intertidal areas. Two temperate benthic diatoms species, Amphora cf. coffeaeformis (C. Agardh) Kütz. and Cocconeis cf. sublittoralis Hendey, were investigated to determine how their photosynthesis responded to temperatures ranging from 5°C to 50°C after short-term exposure (1 h) to a range of irradiance levels (0, 500, and 1,100 μmol photons · m(-2 ) ·( ) s(-1) ). Significant differences were observed between the temperature responses of maximum relative electron transport rate (rETRmax), photoacclimation index (Ek ), photosynthetic efficiency (α), and effective quantum yield (ΔF/Fm' ) in both species. A. coffeaeformis had a greater tolerance to higher temperatures than C. sublittoralis, with nonphotochemical quenching (NPQ) activated at temperatures of 45°C and 50°C. C. sublittoralis, however, demonstrated a more rapid rate of recovery at ambient temperatures. Temperatures between 10°C and 20°C were determined to be optimal for photosynthesis for both species. High temperatures and irradiances caused a greater decrease in ΔF/Fm' values. These results suggest that the effects of temperature are species specific and that short-term exposure to adverse temperature slows the recovery process, which subsequently leads to photoinhibition.

“…Second, three light intensities, including 100 mmol•m −2 •s −1 , 200 mmol•m −2 •s −1 , and 350 mmol•m −2 •s −1 , were tested to explore the optimal illumination intensity appropriate for the isolated epiphytic diatoms grown in the exclusively optimized media (Table 3). The optical density (OD 680 , Multiskan GO, Thermo Fisher Scientific, Waltham, MA, USA; Wang et al, 1997) of diatom inoculum was Experimental design for optimized cultivation and screening of five marine epiphytic diatoms. Four batches of diatom cultures in 10-mL tubes or 5-L flasks were performed in triplicate.…”

IntroductionMarine epiphytic diatoms are natural diets for multiple marine invertebrates, including sea cucumbers, sea urchins, etc. They also act as bioindicators in marine waters to assess water quality of coastal ecosystems. Material and methodsWe isolated three strains of Navicula and two strains of Nitzschia from macroalgal epiphytes. Combined concentrations of four macroelements, five trace metals, and three vitamins in f/2 medium were optimized for these diatoms using single-factor and orthogonal tests. Results and discussionThe biomass productivities for 4-L enlarged cultures of the five isolated diatoms in their exclusively optimized f/2 media all increased by nearly 10-fold relative to f/2 medium, and that of Navicula-1 and Nitzschia-2 reached the highest, i.e., 29.52 ± 1.98 and 30.68 ± 2.84 g m-2 d-1, respectively. Moreover, the relative abundance of C20:5n3 in the exclusively optimized f/2 medium-cultured Navicula-1 notably rose by 24%, and that in Nitzschia-2 held stable at > 25%. Thus, Navicula-1 and Nitzschia-2 were screened out with outstanding growth traits and improved fatty acid compositions at high levels of combined nitrogen, phosphorus, iron, and silicon. The two diatoms have potential for becoming quality diets for marine aquaculture, and ideal candidates for effective nutrient removal.

“…Algae growth is affected by both physiological characteristics and the external driving factors, including light, temperature, nutrients and etc. It was obvious that nitrogen and phosphorus concentration and their ratio in the water body influence the growth velocity, abundance and species of the algae (Fairchild, 1985;Wang Qi hua et al, 1997 and1998;ZHANG Dongpeng, 2000). When the ratio rises from 1.15:0.16 mg/L to 4.45:0.16 mg/L, the benthic diatom biomass increases abruptly (Austin A P, 1990).…”

Every year since 2003, algae bloom has broken out in the branch bay of the Three Gorges Reservoir in Spring. The area affected by the algae bloom is often subject to disturbance which resulting from shipping, storm-runoff event, water conservancy scheduling and wind-wave etc. With its focus on effect of the disturbances on algae growth, this paper took the Xiangxi River Bay as an example. Water was sampled in the duration of algae bloom and compared the chlorophyll-a concentration variation with time under the combined conditions of disturbance, temperature and light through lab experiment, on basis of which the rule of algae growth and the probability of controlling the algae bloom by disturbing the water body was analyzed.
