“…Changes in nucleic acid related to growth have been reported earlier (Mustafa & Jafri 1977). RNA/DNA ratio serves as an index of growth per cell and higher ratios indicate growth increment (Sable 1974). It has been reported that the ratio of ribonucleic acid concentration in body tissues can be used to monitor protein synthesis activity and growth in fish (Bulow 1970; Khan & Jafri 1981).…”

Sugarcane bagasse (T1), paddy straw (T2) and their mixture (T3) were added to mud‐bottomed, manured cement tanks in triplicate to study the effect on bacterial biofilm production and growth and survival of rohu, Labeo rohita. All tanks were stocked with fingerling rohu at 10 000 ha−1. The total plate count (TPC) of bacteria in water and on substrate did not differ significantly between treatments. The mean phytoplankton and zooplankton density in water was the highest in T2, followed by T3 and T1. The growth of fish was significantly (P<0.05) higher in T2 and T3 compared with T1. Significantly higher RNA values were recorded in T2 and T3 compared with T1. Similarly, T2 and T3 registered higher DNA values than T1. RNA:DNA ratio was higher in T2 compared with T1. However, T3 did not differ significantly from T1 and T2. Both intestinal and hepatopancreatic protease and lipase activity was higher in T1 and T2 compared with T3 and both differ significantly from T1. Intestinal amylase activity was higher in T2 and T3 compared with T1, whereas hepatopancreatic amylase activity was higher in T2 compared with T1 and T3. The results demonstrated that production of L. rohita can be significantly increased by the introduction of biodegradable substrates into culture systems where fertilization is employed.

“…The role of growth promoters in enhancing RNA/DNA ratio is supported by earlier findings of Manoj Kumar (1994) and Srinivasa (2000) in common carp and rohu fed with Gprobiotic. The increase in protein synthesis may be reflected in the RNA/DNA ratio, which is basically an index of growth per cell (Sable, 1974;Mustafa and Jafri, 1977;Shyama and Keshavanath, 1991). In conclusion, supplementation of biogut at 0.5% in the basal diets improved growth, weight gain, FCR, PER, net production, RNA/DNA, and digestive enzyme activity in common carp.…”

As from January 2010 The Israeli Journal of Aquaculture-Bamidgeh (IJA) will be published exclusively as an on-line Open Access (OA) quarterly accessible by all AquacultureHub (http://www.aquaculturehub.org) members and registered individuals and institutions. Please visit our website (http://siamb.org.il) for free registration form, further information and instructions. This transformation from a subscription printed version to an on-line OA journal, aims at supporting the concept that scientific peer-reviewed publications should be made available to all, including those with limited resources. The OA IJA does not enforce author or subscription fees and will endeavor to obtain alternative sources of income to support this policy for as long as possible.
