“…The lowest values of dissolved oxygen recorded in both nursery and grow-out rearing during the first week of the experiment in all the treatments are characteristic of water with predominant heterotrophic food production (Moriarty, 1997). Ammonia, nitrite, nitrate, phosphate and alkalinity values recorded in the present study were generally within the suitable limits for fish culture (Azim, 2001;Mridula et al, 2005).…”

Effect of artificial substrates on growth and survival of giant freshwater prawn Macrobrachium rosenbergii (de Man, 1879) in the nursery and grow-out rearing was evaluated. Nursery rearing was conducted for a period of 35 days in nine 1 m 3 cement tubs with 15 cm soil base. Three tubs without substrates served as control (C) while three tubs each with 200 g of sugarcane bagasse (SB) or 200 g of paddy straw (PS) formed the treatments. Each tub was stocked with 15 post-larvae (mean weight, 0.01 g). Grow-out rearing was conducted for 90 days in six 25 m 2 cement cisterns, of which three cisterns without substrate served as control (C) and three with 5 kg sugarcane bagasse (SB) served as treatment. Each cistern was stocked with 25 juveniles (mean weight, 0.55 g). The average phytoplankton and zooplankton abundance in water as well as algae and food organisms attached on the substrate in the nursery phase was greater in bagasse than in paddy straw treatments. Addition of substrate resulted in higher growth and survival both in nursery and grow-out phase. Prawns grown in cisterns provided with substrates were of more uniform size than those in control cisterns. The study recommends the use of substrate based aquaculture for nursery and grow-out rearing of M. rosenbergii.

“…Soil microorganisms play a unique role in the processes of nutrient cycling [1], carbon and nitrogen turnover [2,3], and greenhouse gas emissions [4]. Agricultural management practices, such as cropping rotation, irrigation, and fertilization are known to have significant effects on microbial community structure in soils [5e9], which thereby influence the overall agroecosystem functions [10e12].…”

a b s t r a c tA short-term experiment was carried out in southern China to investigate the effects of land-use conversion from rice paddies to vegetable fields and fertilization on soil microbial community structure by analyzing soil phospholipid fatty acid (PLFA) profiles. A split-plot design with four replicates was adopted, in which land use (paddy and vegetable field) was the first-level treatment and fertilization (conventional fertilization and no fertilization) was nested as the second level. Our results showed that both land-use conversion and fertilization had significant effects on microbial community structure. After 2 years of land-use conversion, the total amount of PLFAs were 3.54 and 2.97 nmol g À1 for fertilized (VeF) and unfertilized (VeNF) vegetable fields, respectively, and 3.19 and 2.32 nmol g À1 for fertilized (R eF) and unfertilized (ReNF) rice paddies, respectively. Soil fungal PLFAs were 1.04 and 0.87 nmol g À1 for VeF and VeNF, respectively, which were significantly increased by 13.9 and 11.4 times compared with those of ReF and ReNF, respectively. The ratio of fungal to bacterial PLFAs significantly increased in vegetable fields compared with rice paddies. No significant differences were found in the total, bacterial, and actinomycetic PLFAs between vegetable fields and rice paddies. The application of fertilizer significantly increased the amount of total PLFAs and bacterial PLFAs. With land-use conversion and fertilization, soil physicochemical properties also changed, and microbial community structure showed a significant relationship with soil water content, NH 4 þ -N, and pH, which explained the land-use conversion and fertilization effects on soil microbial community composition.
