“…Regardless of salinity, the maximum density was very low in C. ellipsoidea at 30°C in this study. This result probably indicates that high temperature is not optimum for growth of C. ellipsoidea , and agrees with Hur's 19 study. SGR and maximum density of C. ellipsoidea linearly decreased with an increase in salinity at 15°C and 20°C, but maximum density linearly increased with increase in salinity at 25°C and 30°C (Table 2).…”

“…The relatively high maximum density of N. oculata at high temperature (25 and 30°C) rather than low temperature (15 and 20°C) at all salinities tested in this study indicate that high temperature is better for achieving the maximum density of N. oculata . Similarly, Hur 19 mentions that N. oculata is more stable than marine Chlorella as food for rotifers above 30°C.…”

“…Green algae commonly used for marine fish hatcheries are Chlorella ellipsoidea and Nannochloris oculata , class Chlorophyceae, 23 because of the ease of mass culture and management, and high nutrient content leading to improvement in larval fish production 5,9,24–28 . Hur 19 demonstrated that N. oculata was superior to C. ellipsoidea as food for rotifers in terms of rotifer growth rate and fatty acid composition during summer. However, no study on the combined effect of temperature and salinity on growth of C. ellipsoidea and N. oculata have been reported.…”

The effects of temperature and salinity on growth of green algae Chlorella ellipsoidea and Nannochloris oculata were determined to compare the optimum culture conditions. A fourtemperature (15, 20, 25, and 30°C) ¥ three-salinity (10, 20, and 30) factorial design with triplicates was applied. Specific growth rate (SGR), maximum density, and duration to reach maximum density of C. ellipsoidea were significantly affected by both temperature and salinity. The highest SGR was observed in C. ellipsoidea at 25°C and salinity 10, but the maximum density was very low. The highest maximum density was achieved in C. ellipsoidea at 15°C and 10. The slope constant of the linear relationship between semilogarithmic growth of C. ellipsoidea and day of culture was highest at 15°C and 10. The SGR and duration to reach maximum density of N. oculata were significantly affected by both temperature and salinity. However, maximum density of N. oculata was significantly affected by temperature, but not salinity. The highest maximum density was achieved in N. oculata at 25°C and 30, but SGR was significantly lower than that of N. oculata at 25°C and 10. The slope constant of the linear relationship between semilogarithmic growth of N. oculata and day of culture was highest at 25°C and 30. Based on these results, the condition of 15°C and salinity 10 seemed to be optimal for maximum density of C. ellipsoidea, and the condition of 25°C and 10 and 30 for SGR and maximum density for N. oculata, respectively.

“…From the mid‐1980s, however, both marine fish and crustacean culture production increased rapidly thanks in part to the advancement of aquaculture technologies. Thus, the production of crustaceans reached 575 tonnes in 1994, a remarkable expansion when compared with production in the 1980s (Hur 1997). On the other hand, shrimp farmers in Korea unfortunately suffered major losses due to viral disease outbreaks, environmental pollution and inadequate pond management (Park, Lee, Lee & Lee 1998; Jee & Kang 2004).…”

This study investigated the e¡ects of di¡erent types of diet and sediment on the growth parameters of juvenile tiger crab Orithyia sinica under laboratory conditions, focusing on survival, growth and moulting. In the ¢rst set of experiments, juvenile tiger crabs were reared with ¢ve di¡erent types of sediment, i.e., soft sand, coarse sand, soft sand mixed with coarse sand, mud or bare bottom. Soft sand resulted in not only the highest survival rate of 78% but also the best rate of growth and feed intake. Crabs reared with a mud substrate showed the worst results in these parameters. The intermoult period, however, was not affected by sediment types. In the second set of experiments, crabs were fed di¡erent types of diet to determine their e¡ects on the same growth parameters. Diets were composed of di¡erent combinations with Manila clam (Ruditapes philippinarum), brine shrimp (Artemia nauplii), microencapsulated feeds and marine diatom (Chaetoceros gracilis). Survival and growth in crabs fed Manila clam as a diet component were signi¢cantly higher than in those on other diets. The highest survival and growth were achieved with a diet that included all four components. These results provide valuable information on the appropriate bottom substrates and diet types necessary for arti¢cial mass culture of the tiger crab.
