Live plankton supplementation improves growth and health status of marron (Cherax cainii Austin 2002)

Effects of carbon source addition in rearing water on sediment characteristics, growth and health of cultured marron (Cherax cainii)

“…Results of the current study reveal that molasses treatment increased protease activity in marron hepatopancreas, resulting in the highest moult weight increment and specific growth rate of marron which is in line with the results documented in other studies 29,30 . The lower specific growth rate of marron in the current study is in contrast to the findings of Tulsankar et al 8 , which might be associated due to a larger size of marron used as experimental animal. Moisture and immunological parameters have been widely used as robust indicators of marron health conditions 2 .…”

“…In the present study, all three exogenous carbon sources included in the marron culture did not significantly affect marron survival, marron weight gain; however specific growth rate, and moult weight increment were improved. The survival rate of the marron in this study was comparable to those reported in a previous study 8 , which may be due to the same approach of housing the marron individually to prevent cannibalism. Moreover, heterotrophic bacteria presented in the carbon-enriched treatments could assimilate nitrogenous waste and convert it into protein-rich microbial biomass, thereby supplying the nutrients for the growth www.nature.com/scientificreports/ of aquatic organisms 30,43 .…”

“…Like other decapods, the natural habitat of marron is the sediment–water interface which is the boundary between the bottom and overlying water column. The detritus/sediment is recognised as a vital in-situ food source for marron nutrition 8 . However, research efforts to decode the sediment characteristics in marron aquaculture is still in infancy stage, and its effects on marron growth and health parameters are obscure.…”
