Culture of Moina macrocopa Using Different Types of Organic Wastes

Abstract

Moina macrocopa was cultured with different animal manures (chicken manure, pig manure and cow manure) and food waste to determine the impact of these food sources on its mass production. All diets were provided at five different concentrations: 500, 1000, 2500, 5000 and 10000 ppm. Gross and net reproductive rates were higher in 1000 ppm concentration of food waste medium and the highest average population growth was obtained of about 9 org mL-1 whereas pig manure treatment showed the lowest among all the culture medium. The highest population density was observed in low concentration treatments, on the contrary, higher concentrations showed an adverse effect on M. macrocopa cultivation. The results of this study suggest that 1000 ppm concentration of food waste produces better results than other animal manures which showed the highest population density and exhibited a comparatively higher percentage of highly unsaturated fatty acids than the other treatments and could be an inexpensive and sustainable cultivation approach of Moina macrocopa.

Enhancement of protein, lipid and fatty acids in copepod, Oithona rigida for the improvement of growth, development and survival of early‐stage mud crab larvae ( Scylla olivacea )

“…(Roustaian et al, 2001) reported similar declines in the fatty acid composition of the larval freshwater prawn, Macrobrachium rosenbergii , as well as the use of caloric‐rich lipids to sustain swift morphology and consistent swim‐like behaviour correlated with food selection. These results were supported by research in P. pelagicus larvae, which decreased the level of EPA, DHA and ARA, suggesting that the HUFAs requirement decreased when the larval stage increased (Kabery et al, 2019). This form of the metabolism of fatty acids has also been reported for larvae of marine crustaceans, S. serrata and for species with life‐cycle close to that of S. olivacea , the reductions in tissue lipids during ontogeny can be related to larval buoyancy (Holme et al, 2009; Vadher, 2020).…”
