“…Rice bran also serves as a direct food source for cladocera (De Pauw et al 1981 ), provides satisfactory and stable water quality, and reduces the incidence of filamentous algae ). In the present study, higher survival and significantly greater yields were obtained in ponds fertilized with RB than those in ponds fertilized with DS.…”

fro agro-industrial by-products, rice bran (RB) and distillers dried solubles (DS), and a prepared diet (PD) were evaluated as organic fertilizers for the production of juvenile paddlefish in nine 0.02-ha earthen ponds over a 40-day culture period. Paddlefish yield from ponds fertilized with RB (209 kgha) was significantly greater (P S 0.05) than that from ponds fertilized with DS (129 kgha), but it was no1 significantly greater than yields from ponds fertilized with PD (258 kgha). Fish survival from ponds fertilized with PD (79%) was significantly higher than from ponds fertilized with RB (55%) or DS (50%). There was no signif~cant difference in Agricultural Experiment Station, Auburn University, AL 36849. USA.

“…This interest increased dramatically during the last two decades toward (1) the management and optimal use of natural systems for rearing aquatic organisms (Geiger, 1983), and (2) the use of various freshwater and marine planktonic organisms as food, their culture, automatic sampling, and nutritional quality (e.g. Barnabe, 1980;De Pauw et al, 1981;Kahan etal., 1981;Turk etal., 1982;Watanabe etal., 1983;Lubzens, 1987;Cruz & James, 1989;Villegas, 1990).…”

Sampling and experiments were performed in brackish fishponds, located near the Ebrie Lagoon, Ivory Coast. Moina developed here at salinities up to about 4 g -1. Mean embryonic and juvenile development times in experimental conditions were 0.82 and 0.80 day, respectively, with 2 juvenile stages at 30 C (salinity of 3 g l-1; 29 ytg chlorophyll-a 1-1) and 1.22 and 1.37, with 2 stages for most individuals and 3 or 4 stages for some of them at 26 C (2 g l-1 and 36 yug 1-1). The corresponding Q o for embryonic development was relatively high (2.7). Growth rates in weight at 30 C were 2.11 and 1.37 bg /xg-g d-, respectively, for the embryonic and juvenile stages, 0.21 for mean somatic growth of the five first female adult stages, and 1.00 for primipara, summed for somatic growth, production of eggs, and embryonic growth. Consequently, differences in growth rates between young and adults were small. M. micrura also was a high fecundity species according to its size, fecundity in nature varying from 2.2 to 7.7 eggs per adult female. Rates of population increase evaluated for some sequences of parthenogenetic growing periods, reached up to 0.9. Most of the daily P/B evaluated by the cumulative growth method reached values above 1.0 (28 to 31 C), minima being about 0.7 for lower temperatures (approximatively 26 °C ). Populations were also characterized by low juvenile to adult ratios (down to 0.9) and high daily birth rates (up to 1.2). Overall, M. micrura is a highly productive, opportunistic species, well adapted to the low salinities that occur during part of the year in the ponds.Biological and population characteristics of this species, and literature data on regulation mechanisms, possible use for aquaculture, and on size in tropical species are discussed.

“…Rice bran was used as feed in both Daphnia and Artemia cultures (Sorgeloos et al, 1980;Depauw et al, 1981). Rice bran and cassava bran could directly be used as M. macrocopa feed, although they have to be proccessed into small particles suspension in order to fit the the mouth of M. macrocopa.…”

Moina macrocopa culture density can be improved by optimizing the fecundity, and somatic growth through the regulation of quality and quantity of feed. The purpose of this study were to determined how to use effectively the rice bran and cassava bran Manihot utilisima suspension on Moina, based on population, neonates production, adult percentage, biomass, metabolisme and nutritional state. In this study, Moina were cultured for eighth days using four concentrations of rice bran suspension and three concentrations of cassava suspension. This research found that M. macrocopa culture with rice bran suspension has higher population, neonates production, adult percentage and biomass than its culture with cassava bran suspension (P<0.05). This study also found that Moina culture with rice bran suspension has higher total value of RNA, total value of DNA, the ratio RNA/ DNA, FCR, and concentration of protein and amino acid than Moina culture with cassava bran suspension. Treatment D with the initial rice bran suspension concentration was 0.3 mL/L and was increased starting the second day and the end concentration on the eighth day was 1.2 mL/L has highest peak population of Moina 17,975 ind/L in seventh day, weight wet biomass 439 mg/L in eighth day and lower FCR 0.94.Keywords: suspension, rice bran, cassava, population, ratio RNA/DNA ABSTRAK Kepadatan populasi dalam budidaya Moina macrocopa dapat ditingkatkan dengan mengoptimalkan fekunditas dan pertumbuhan somatik melalui pengaturan kualitas dan kuantitas pakan. Penelitian ini bertujuan untuk menganalisis efektifitas pengunaan pakan suspensi dedak dan tepung ketela pohon Manihot utilisima dalam budidaya M. macrocopa terhadap populasi, produksi anak per induk, persentase dewasa, biomasa, FCR, dan metabolismenya (asam amino, DNA, RNA, dan RNA/DNA). Di dalam penelitian ini, M. macrocopa dibudidayakan selama delapan hari menggunakan empat konsentrasi suspensi dedak dan tiga konsentrasi suspensi tepung ketela pohon. Hasil penelitian ini menunjukkan bahwa, budidaya M. macrocopa dengan pakan suspensi dedak menghasilkan populasi, produksi anak/induk, persentase dewasa dan biomasa yang lebih tinggi dibandingkan budidaya Moina dengan pakan suspensi ketela pohon (P<0,05). Budidaya M. macrocopa dengan pakan suspensi dedak juga menghasilkan total RNA, total DNA dan nisbah RNA/DNA, konsentrasi protein, dan asam amino yang lebih tinggi dibandingkan Moina dengan pakan suspensi ketela pohon. Perlakuan D dengan pakan suspensi dedak awal 0,3 mL/L dan meningkat mulai hari kedua dengan konsentrasi hari kedelapan 1,2 mL/L menghasilkan puncak populasi tertinggi pada hari ketujuh sebanyak 17.975 ind/L, berat basah biomasa hari kedelapan kultur 439 mg/L, dan FCR yang rendah yaitu 0,94.Kata kunci: suspensi, dedak, ketela pohon, populasi, nisbah RNA/DNA
