The sap of Acer mono has been called 'bone-benefit-water' in Korea because of its mineral and sugar content. In particular, the calcium concentration of the sap of A. mono is 37.5 times higher than commercial spring water. In the current study, we examined whether A. mono sap could improve or prevent osteoporosis-like symptoms in a mouse model. Male mice (3 weeks old) were fed a low-calcium die...
The freshwater angelfishes (Pterophyllum) are South American cichlids that have become very popular among aquarists, yet scarce information on their culture and aquarium husbandry exists. We studied Pterophyllum scalare to analyze dietary effects on fecundity, growth, and survival of eggs and larvae during 135 days. Three diets were used: A) decapsulated cysts of Artemia, B) commercial dry fish...
Biofloc systems in Pacific white shrimp (Penaeus vannamei) culture generate floccules that remove wastes, and hence, biofloc formation is promoted for production. This study evaluated the induction of using microalgae probiotic bacteria hyper-intensive culture. The experiment was performed six weeks tanks (28,000 L each) stocked 350 ind m-3 weight 1400 ± 30 mg. Three treatments were assessed: 1...
Abstract Biofloc technology is much highlighted these days because of its tremendous effects on aquaculture. Microbes were enriched cheapest organic carbon source i. e., powdered banana peels and incorporated in different aquaria rearing grass carp fingerlings under C/N treatments (10:1, 15:1 20:1) 10% water daily exchange. The initial growth was recorded. experiment settled triplicates for 60 ...
Onfarm trial were conducted to evaluate the effects of feeding on pellets with different protein levels in the presence and absence of the bioflocs on water quality, survival and growth of the green tiger shrimp (Penaeus semisulcatus) in intensive types of shrimp culture systems. Five different feeds were formulated. Four biofloc treatments (BFT) and one control were managed in 10 greenhouses e...

Effect of different feeding levels on water quality, growth performance, survival rate and body composition of Pacific white shrimp Litopenaeus vannamei post larvae were studied in zero water exchange system. Shrimp post larvae with mean weight of 74.46± 6.17 mg were fed for 32 days in 300L fiberglass tanks containing 130L water at density of 1 post larvae L-1. There were five treatments includ...
